I love using the crockpot for spiral ham because it makes a tender, juicy centerpiece with almost no fuss, and I’ll show you how to pick the right size, prep it, and make glazes that really stick between the slices.
I’ll walk you through classic brown-sugar and maple-mustard options, a low-sugar choice, and timing tips so nothing dries out—plus quick sides and storage ideas—so you can relax and still serve something that looks and tastes special.
Why a Crockpot Is Perfect for Spiral Ham

A crockpot is ideal for cooking a spiral ham because it gently reheats and infuses the meat with glaze while keeping it moist; the low, even heat prevents drying and allows flavors to penetrate between the slices, and the hands-off cooking means you can prepare glaze and sides while it warms slowly to perfect serving temperature.
- 1 fully cooked spiral-cut ham (6–8 lb)
- 1 cup brown sugar
- 1/2 cup honey or maple syrup
- 1/4 cup Dijon mustard
- 1/4 cup orange juice or apple cider
- 2 tbsp apple cider vinegar
- 1 tsp ground cloves or 6 whole cloves
- 1/2 tsp black pepper
- 1/4 cup water or reserved ham juices
- Fresh rosemary or thyme sprigs (optional)
Place the ham cut-side down in a 6-quart crockpot and tuck rosemary if using; whisk brown sugar, honey, mustard, orange juice, vinegar, cloves and pepper with water and pour over and between slices as much as possible, cover and cook on LOW for 3–4 hours (until heated through to 140°F), basting once or twice and brushing additional glaze on top in the last 20 minutes, then remove and tent with foil for 10 minutes before serving.
Tip: For best results, reserve any juices during carving to mix with remaining glaze and spoon over slices, and avoid high heat which will dry the ham. A slow cooker also helps maintain consistent low heat to keep the spiral ham tender and evenly warmed throughout.
Choosing the Right Spiral Ham Size for Your Slow Cooker

Choosing the right-sized spiral ham for your slow cooker guarantees even reheating and room for glaze to penetrate; pick a ham that fits comfortably (cut-side down) with a little space around it so heat circulates—typically a 6–8 lb ham for a 6-quart crockpot, smaller hams (3–5 lb) for 4–5 quart units, or consider trimming the bone to fit larger hams or using a roasting pan if necessary.
- 1 fully cooked spiral-cut ham (choose size to fit your crockpot)
- 1 cup brown sugar
- 1/2 cup honey or maple syrup
- 1/4 cup Dijon mustard
- 1/4 cup orange juice or apple cider
- 2 tbsp apple cider vinegar
- 1 tsp ground cloves or 6 whole cloves
- 1/2 tsp black pepper
- 1/4 cup water or reserved ham juices
- Fresh rosemary or thyme sprigs (optional)
Place the ham cut-side down in the slow cooker, trimming a bit of the bone if needed so the lid closes; whisk the remaining ingredients into a smooth glaze, pour and work some between slices, cook on LOW for 3–4 hours until internal temperature reaches 140°F, baste once or twice and brush extra glaze on top during the last 20 minutes, then remove and tent with foil for 10 minutes before carving.
Tip: If your ham is oversized, remove and reserve the bone then lay slices in layers with glaze between them or use a larger oven method; always check fit before heating and avoid HIGH settings to prevent drying.
Slow cooking a whole ham shares similarities with preparing a whole chicken in that gentle, low heat helps keep the meat tender and juicy.
Preparing Your Ham: Trimming, Scoring, and Placement

Preparing your ham for the crockpot guarantees even heating, easy glazing, and an attractive final presentation; trim excess skin and large fat flaps so the lid fits, remove and reserve the bone if you need to layer slices later, and score the ham’s fat in a shallow diamond pattern about 1/4 inch deep to let glazes seep between slices.
- 1 fully cooked spiral-cut ham sized to fit your slow cooker
- Trimming knife and kitchen shears
- 1 cup brown sugar (for glaze or rubbing into scores)
- 1/2 cup honey or maple syrup (for glazing)
- 1/4 cup Dijon mustard (optional for tang)
- 1/4 cup orange juice or apple cider (for moisture)
- 2 tbsp apple cider vinegar (for brightness)
- 1 tsp ground cloves or 6 whole cloves (optional for aroma)
- 1/2 tsp black pepper
- 1/4 cup water or reserved ham juices
- Fresh rosemary or thyme sprigs (optional for aromatics)
- Aluminum foil and a meat thermometer
Trim off any loose skin and excess fat so the crockpot lid closes, use kitchen shears or a sharp knife to remove large fat flaps and, if necessary, remove and reserve the bone to lay slices in layers; lightly score the remaining fat in a diamond pattern about 1/4″ deep to accept glaze, place the ham cut-side down in the slow cooker with a splash of water or reserved juices in the bottom, whisk glaze ingredients together and spoon some between slices, cook on LOW for 3–4 hours until the internal temperature reads 140°F, baste once or twice and brush extra glaze on during the last 20 minutes, then remove and tent with foil for 10 minutes before carving.
Tip: If your ham barely fits, trim the bone and layer slices with glaze between them, avoid HIGH heat to prevent drying, and always confirm fit before turning the cooker on.
Always check that the ham is marked as fully cooked before reheating to ensure safe and proper preparation.
Classic Brown Sugar and Honey Glaze Recipe

A classic brown sugar and honey glaze brings sweet, glossy richness to a crockpot spiral ham, seeping into the scored fat and between slices as it cooks slowly; this recipe balances brown sugar and honey with a touch of mustard and citrus for brightness, giving a caramelized finish without drying the meat.
- 1 fully cooked spiral-cut ham sized to fit your slow cooker
- 1 cup packed brown sugar
- 1/2 cup honey
- 1/4 cup Dijon mustard
- 1/4 cup orange juice or apple cider
- 2 tbsp apple cider vinegar
- 1 tsp ground cloves or 6 whole cloves
- 1/2 tsp black pepper
- 1/4 cup water or reserved ham juices
- Fresh rosemary or thyme sprigs (optional)
- Aluminum foil and a meat thermometer
Place the trimmed, scored ham (cut-side down) in the slow cooker with 1/4 cup water or reserved juices, whisk brown sugar, honey, mustard, orange juice, vinegar, cloves, and pepper until smooth and spoon some glaze into the scored cuts and between slices; cook on LOW for 3–4 hours, basting once or twice, brushing extra glaze on during the last 20 minutes, and remove when the internal temperature reaches 140°F, then tent with foil for 10 minutes before serving.
Tip: If your ham is tight in the crockpot, trim the bone and layer slices with glaze between them, avoid HIGH heat to prevent drying, and always confirm fit before turning the cooker on.
Crockpots allow for hands-off cooking and gentle heat that helps keep large cuts, like turkey, moist and tender—consider using a low-and-slow approach when adapting recipes for similar results.
Maple-Mustard Glaze With a Tangy Twist

A maple-mustard glaze with a tangy twist brightens a crockpot spiral ham by combining sweet maple syrup, Dijon mustard, and apple cider vinegar with a splash of citrus and a hint of horseradish for warmth; cooked slowly, the glaze permeates into the scored fat and between slices, producing a glossy, slightly tangy finish that complements the ham’s natural saltiness without overpowering it.
- 1 fully cooked spiral-cut ham sized to fit your slow cooker
- 3/4 cup pure maple syrup
- 1/3 cup Dijon mustard
- 2 tbsp whole-grain mustard
- 1/4 cup apple cider vinegar
- 2 tbsp orange juice
- 1 tbsp prepared horseradish (optional, for tang)
- 2 tbsp brown sugar
- 1/2 tsp ground allspice or 4 whole cloves
- 1/4 tsp black pepper
- 1/4 cup water or reserved ham juices
- Fresh parsley or thyme for garnish (optional)
Place the ham cut-side down in the crockpot with 1/4 cup water or reserved juices; whisk maple syrup, Dijon, whole-grain mustard, apple cider vinegar, orange juice, horseradish, brown sugar, allspice, and pepper until smooth, spoon and work some glaze into the scored cuts and between slices, cover and cook on LOW for 3–4 hours, basting once or twice and brushing additional glaze on during the last 20 minutes, and remove when the internal temperature reads 140°F, tent with foil for 10 minutes before slicing and serving.
Tip: If the ham is a tight fit, trim the bone or layer slices with glaze between them, avoid HIGH heat to prevent drying, and check internal temperature with a meat thermometer to guarantee perfect doneness.
For a richer, more savory base you can brown the ham briefly in a hot skillet before transferring to the crockpot to enhance flavor development.
Sweet-And-Spicy Glaze With Pineapple and Chili

A sweet-and-spicy glaze with pineapple and chili enlivens a crockpot spiral ham by blending canned pineapple juice and brown sugar with chili paste and red pepper flakes for heat, plus a touch of soy sauce and vinegar to balance sweetness; the glaze seeps into the cut slices as it cooks low and slow, and finishing with fresh pineapple chunks gives bursts of bright acidity that contrast the ham’s savory richness.
- 1 fully cooked spiral-cut ham sized to fit your slow cooker
- 1 cup canned pineapple juice (reserve 1/4 cup)
- 1/2 cup brown sugar (light or dark)
- 1/3 cup pineapple preserves or crushed pineapple with syrup
- 2 tbsp soy sauce or tamari
- 1–2 tbsp gochujang or sambal oelek (adjust to taste)
- 1 tsp red pepper flakes (optional)
- 2 tbsp apple cider vinegar
- 1 tbsp Dijon mustard
- 1 tbsp cornstarch mixed with reserved 1/4 cup pineapple juice (slurry)
- 1 cup fresh or canned pineapple chunks
- 1/4 tsp ground ginger or 1 tsp grated fresh ginger
- 1/4 tsp black pepper
Place the ham cut-side down in the crockpot with 1/4 cup water or reserved ham juices, whisk together pineapple juice, brown sugar, preserves, soy sauce, gochujang or sambal, red pepper flakes, apple cider vinegar, Dijon, ginger and pepper until smooth and pour over the ham, cover and cook on LOW for 3–4 hours basting once or twice; during the final 20–30 minutes, stir the cornstarch slurry into the glaze in a small saucepan and simmer until slightly thickened, spoon the thickened glaze and pineapple chunks over the ham, continue cooking until the internal temperature reaches 140°F, then tent with foil for 10 minutes before serving.
Tip: Taste and adjust heat and sweetness before glazing, avoid high heat to prevent drying, and remove excess glaze from the crockpot to use as a sauce for serving. A slow cooker is ideal for retaining moisture and ensuring even reheating when finishing a pre-cooked ham, especially with low-and-slow cooking.
Low-Sugar and Keto-Friendly Glazing Options

For a low-sugar, keto-friendly glaze that still delivers savory-sweet depth on a crockpot spiral ham, swap out cane sugars and fruit syrups for sugar-free sweeteners, concentrated flavor boosters, and a touch of acid and fat to carry flavor; this version uses erythritol or monk fruit, unsweetened pineapple extract (or a few drops of liquid smoke and pineapple flavor), Dijon, soy or tamari, a little mustard and apple cider vinegar, butter or olive oil to round the mouthfeel, and optional chili for heat—glaze seeps into the slices as the ham cooks low and slow, giving classic taste without the carbs.
- 1 fully cooked spiral-cut ham sized to fit your slow cooker
- 1 cup water or reserved ham juices
- 1/4 cup sugar-free pineapple extract or 2 tsp unsweetened pineapple-flavor concentrate
- 1/3 cup powdered erythritol or equivalent monk fruit sweetener
- 2 tbsp Dijon mustard
- 2 tbsp soy sauce or tamari (or coconut aminos)
- 1 tbsp apple cider vinegar
- 2 tbsp butter or 2 tbsp olive oil
- 1–2 tsp liquid smoke (optional)
- 1–2 tsp hot sauce or 1/2–1 tsp red pepper flakes (optional)
- 1/4 tsp ground ginger or 1 tsp grated fresh ginger
- 1/4 tsp black pepper
Place the ham cut-side down in the crockpot with 1/2 cup water or reserved ham juices, whisk together water, sugar-free pineapple extract, erythritol, Dijon, soy/tamari, apple cider vinegar, butter (melted), liquid smoke (if using), hot sauce, ginger and pepper until smooth and pour over the ham, cover and cook on LOW for 3–4 hours or until heated through (140°F internal), basting once or twice.
If you want a thicker glaze, dissolve 1 tsp glucomannan or 1/2 tsp xanthan gum into a small amount of warm water and whisk it into the glaze in the last 15–20 minutes of cooking to slightly thicken, then spoon over the ham and tent for 10 minutes before slicing and serving.
Tip: Taste and adjust sweetness and saltiness before glazing, avoid cooking on HIGH to prevent drying, and use a small amount of xanthan or glucomannan to thicken without adding carbs.
You can also adapt timing and liquid amounts when cooking other proteins like turkey breast in the crockpot to maintain juiciness and even heating.
Timing and Temperature Guidelines to Keep Ham Juicy

Keeping a spiral-cut crockpot ham juicy means gentle, consistent heat, plenty of moisture, and timing keyed to internal temperature rather than clock hours; this recipe outlines low-and-slow cooking with a light glaze/broth base, thermometer checks to reach 140°F, and brief rest time so the juices redistribute for tender, flavorful slices.
- 1 fully cooked spiral-cut ham sized to fit your slow cooker
- 1 cup low-sodium chicken broth or reserved ham juices
- 1/2 cup low-sugar glaze (see previous subtopic or use 1/3 cup erythritol-based glaze + 2 tbsp Dijon)
- 2 tbsp butter or olive oil
- 1 tbsp apple cider vinegar or lemon juice
- 1 tsp liquid smoke (optional)
- 1 tsp garlic powder
- 1/2 tsp ground black pepper
- 1–2 sprigs fresh thyme or 1/2 tsp dried thyme
- Thermometer (instant-read or probe)
Place the ham cut-side down in the crockpot, pour the broth and glaze mixture over and around the ham, tuck thyme sprigs into the cavity, cover and cook on LOW until an instant-read thermometer inserted into the thickest slice (not touching bone) reads 140°F—this typically takes 3–4 hours for most hams but check after 2½ hours to avoid overcooking; baste once at halfway point and, if desired, switch to WARM for up to 30 minutes once 140°F is reached while tenting with foil to rest before serving.
Tip: Monitor temperature not time, keep liquid in the crockpot to maintain humidity, avoid HIGH heat, rest ham 10–15 minutes tented to let juices redistribute, and remove foil briefly to glaze/broil if you want a caramelized finish.
This method pairs well with a slow cooker pork loin for complementary low-and-slow cooking techniques and flavors.
Serving Suggestions and Easy Sides for Holiday Meals

For a complete holiday plate that complements a juicy crockpot spiral ham, this recipe pairs the ham with simple, make-ahead sides that reheat well and can be mostly assembled before guests arrive: maple-roasted sweet potatoes, a bright mustardy green bean salad, and soft dinner rolls. These dishes balance the ham’s saltiness and glaze, require minimal active cooking during your dinner service, and scale easily for larger gatherings.
- 2 lb sweet potatoes, peeled and cut into 1-inch cubes
- 2 tbsp olive oil
- 2 tbsp pure maple syrup
- 1 tsp kosher salt
- 1/2 tsp ground black pepper
- 1 lb green beans, trimmed and blanched
- 1/4 cup toasted sliced almonds
- 2 tbsp Dijon mustard
- 1 tbsp apple cider vinegar
- 2 tbsp olive oil (for dressing)
- 1 tsp honey
- 12 soft dinner rolls (store-bought or refrigerated dough)
Preheat oven to 425°F (220°C); toss sweet potato cubes with 2 tbsp olive oil, maple syrup, salt and pepper and spread on a rimmed baking sheet and roast 20–25 minutes until caramelized, turning once;
meanwhile blanch green beans 2–3 minutes in boiling salted water, shock in ice water, drain and toss with Dijon, apple cider vinegar, 2 tbsp olive oil and honey, then fold in toasted almonds and refrigerate until serving;
warm dinner rolls in a 350°F oven for 8–10 minutes wrapped in foil just before serving and reheat roasted sweet potatoes on a sheet pan at 350°F for 10–12 minutes if made ahead.
Tip: Assemble sides ahead—roast potatoes and prep beans up to 2 days in advance and reheat gently; dress beans just before serving for best texture and hold rolls wrapped to keep soft. Slow cookers are great for stretching your holiday budget and feeding a crowd, especially with cheap crockpot meals that maximize flavor on a small budget.
Make-Ahead, Storage, and Reheating Tips

Make-Ahead, Storage, and Reheating Tips for a crockpot spiral ham and its suggested sides help you enjoy a relaxed holiday meal by prepping components in advance, storing them safely, and reheating gently to preserve texture and flavor; follow the timeline and temperatures below to cook, cool, refrigerate or freeze, and reheat the ham, roasted sweet potatoes, green bean salad, and rolls with minimal last-minute work.
- Fully cooked spiral ham (6–8 lb)
- 1 cup glaze (maple Dijon or brown sugar mustard)
- 2 lb sweet potatoes, peeled and cubed
- 2 tbsp olive oil
- 2 tbsp maple syrup
- 1 tsp kosher salt
- 1/2 tsp black pepper
- 1 lb green beans, trimmed and blanched
- 1/4 cup toasted sliced almonds
- 2 tbsp Dijon mustard
- 1 tbsp apple cider vinegar
- 2 tbsp olive oil (for dressing)
- 1 tsp honey
- 12 dinner rolls
Place the spiral ham in the crockpot with 1/2 cup water or apple juice, brush with half the glaze, cover and cook on low for 2–3 hours until heated through (internal temp 140°F), tent with foil and keep warm.
Roast sweet potatoes at 425°F for 20–25 minutes until caramelized, cool completely before storing.
Blanch green beans 2–3 minutes, shock in ice water, drain and refrigerate undressed.
Reheat ham in crockpot on low with remaining glaze for 30–60 minutes, warm potatoes on a sheet pan at 350°F for 10–15 minutes, dress beans just before serving and heat rolls wrapped in foil at 350°F for 8–10 minutes.
Tip: Cool cooked foods quickly (shallow containers, fridge within 2 hours), store ham and sides in airtight containers for up to 4 days (or freeze up to 2 months), reheat gently to avoid drying and dress salads at the last minute for best texture. For exceptionally tender results, consider slow-cooking meat cuts similarly to how you would make tender crockpot pork ribs before serving.
