Butter chicken is the dish that made me fall in love with Indian cooking, and this slow cooker version keeps every bit of that silky, gently spiced magic while letting your Crockpot do the babysitting. You brown the chicken for 6 minutes, blend a quick sauce, and walk away for 3 hours.

The trick is a two-part sauce: a spiced tomato base that simmers low and slow, then butter and cream stirred in at the very end so nothing breaks or turns grainy. That final swirl is what makes it taste like a restaurant plate instead of a slow cooker shortcut.
Serve it over basmati rice or scoop it up with warm naan. Either way, plan for leftovers, because this makes 6 generous portions and it reheats beautifully the next day.
Why You'll Love This Recipe
About the Ingredients
2.5 lbs (1.13 kg) boneless skinless chicken thighs, cut into 1.5-inch chunks
Thighs stay juicy through the long cook; chicken breast works but add it in the last 90 minutes. Buy thighs labeled 'boneless skinless' so you skip all trimming.
1 tbsp (15 ml) neutral oil, such as avocado or canola
Used only for the quick sear. Any high-smoke-point oil works; skip olive oil here since it smokes at this heat.
1 large yellow onion, roughly chopped (about 1.5 cups / 200 g)
Yellow onion gives sweetness; a red onion makes the sauce slightly sharper. Frozen chopped onion works in a pinch, no thawing needed.
4 garlic cloves, peeled
Fresh garlic beats jarred here. If using jarred minced garlic, use 1 tablespoon (15 ml) and add it with the sauce, not the blender.
1 tbsp (about 12 g) freshly grated ginger
Freeze your ginger knob first and it grates into fluffy shreds with no stringy fibers. Ground ginger is a last resort: use 1 tsp.
1 can (6 oz / 170 g) tomato paste
Tomato paste gives that deep brick-red color. If you only have crushed tomatoes, use 1.5 cups and reduce the cream to 3/4 cup.
1 can (14.5 oz / 411 g) diced tomatoes, undrained
Fire-roasted diced tomatoes add a subtle smoky note. Regular diced is completely fine.
2 tsp (about 6 g) garam masala, plus 1 tsp for finishing
Buy garam masala from a busy spice aisle or an Indian market; it fades fast. Curry powder is a decent swap but tastes different, not identical.
1 tsp (about 3 g) ground cumin
Whole cumin seeds toasted and ground are stronger, but pre-ground is what most of us keep. Check the date; stale cumin tastes like dust.
1 tsp (about 6 g) fine sea salt, plus more to taste
Kosher salt needs about 1.5 tsp to match. Add salt in two stages: once in the sauce, once after the cream goes in.
1/2 cup (1 stick / 113 g) unsalted butter, cut into cubes
Unsalted lets you control the salt. Salted butter works; just cut the added salt to 1/2 tsp.
1 cup (240 ml) heavy cream, at room temperature
Room temperature cream is the secret to a smooth sauce; cold cream can look slightly grainy at first. Full-fat coconut cream makes it dairy-free.
Tips & Tricks
- Do not skip the 6-minute sear. Browning the chicken at 425F (220C) in a hot skillet builds flavor the slow cooker cannot create on its own.
- Add the cream and butter only in the last 15 minutes. Boiling cream for 3 hours is the number one reason slow cooker butter chicken turns grainy.
- Taste before serving. Slow cookers trap moisture, so the sauce can taste flat after 3 hours; a final pinch of salt and 1 tsp garam masala wakes it right up.
- Keep the lid on. Every peek drops the internal temperature and adds 15 to 20 minutes of cook time.
Pro Tips
Step-by-Step Instructions
1. Sear the chicken
Heat 1 tbsp oil in a large skillet over medium-high heat, about 425F (220C). Add half the chicken in a single layer and cook 3 minutes per side until golden brown on the edges; it will not be cooked through yet, and that is fine. Repeat with the second batch, then transfer all chicken to the Crockpot.
2. Bloom the spices
Lower the skillet to medium (about 350F / 175C) and stir in the garam masala and cumin for 30 seconds until fragrant and slightly darkened. Scrape every bit into the Crockpot; those browned bits are flavor.
3. Blend the sauce
Add onion, garlic, ginger, tomato paste, and diced tomatoes to a blender and blend 30 seconds until completely smooth, with no visible onion flecks. Pour over the chicken and stir in 1 tsp salt.
4. Slow cook on low
Cover and cook on LOW for 3 hours (or HIGH for 1.5 hours). The chicken is done when it shreds easily with a fork and reaches 165F (74C) at the thickest piece. Avoid lifting the lid before the 3-hour mark.
5. Finish with butter and cream
Turn the Crockpot to LOW if it is not already, and stir in the cubed butter until fully melted, about 1 minute. Pour in the room-temperature cream and the last 1 tsp garam masala, stirring gently until the sauce turns an even, glossy orange.
6. Thicken if needed
If the sauce looks thin, leave the lid off for 15 to 20 minutes on LOW, stirring once halfway. It is ready when it coats the back of a spoon and the edges bubble gently.
7. Taste and serve
Taste and add salt in 1/4 tsp increments until the flavors pop. Serve hot over basmati rice or with naan, and scatter with cilantro if you like.
Delicious Variations
Dairy-Free Coconut
Swap the butter for 3 tbsp coconut oil and the cream for 1 cup full-fat coconut cream. Add it off heat so it does not split.
Extra Veggie
Stir in 2 cups of cauliflower florets or baby spinach in the last 30 minutes for a one-pot meal.
Spicier Kick
Add 1 to 2 tsp Kashmiri chili powder with the spices, or a sliced serrano in the last hour for real heat.
How to Store Crockpot Butter Chicken
Refrigerator
Store in an airtight container in the refrigerator for up to 4 days. The sauce thickens as it chills; that is normal.
Freezer
Freeze in portion-sized containers for up to 3 months. Cool completely first, and leave 1 inch of headspace since the sauce expands.
Reheating
Reheat gently on the stovetop over medium-low heat or in the microwave in 1-minute bursts, stirring between. Add a splash of cream or water if it looks thick.
Frequently Asked Questions
Q: Can I put raw chicken in a Crockpot for butter chicken?
Yes, but browning it first is what makes this taste like butter chicken instead of plain stewed chicken. The 6-minute sear adds deep roasted flavor that the slow cooker cannot create. If you are short on time, you can skip it, but expect a milder result.
Q: Why did my butter chicken sauce curdle?
Curdling almost always comes from adding cold cream or boiling the cream for too long. Stir in room-temperature cream and butter only in the final 15 minutes on LOW. If it does look slightly grainy, whisk in 1 tbsp of warm cream and it usually smooths out.
Q: How long do I cook butter chicken in a Crockpot?
Cook on LOW for 3 hours or on HIGH for 1.5 hours with chicken thighs. If you use chicken breast, cut the time to 2 hours on LOW since lean meat dries out fast. Always check for 165F (74C) internal temperature.
Q: Is butter chicken very spicy?
No, authentic butter chicken is mild and creamy, not hot. The warmth comes from garam masala and ginger, not chili. If you want heat, add 1 tsp Kashmiri chili powder or a sliced serrano pepper.
Q: Can I make Crockpot butter chicken ahead of time?
Yes, and it tastes even better the next day as the spices settle. Cook it fully, cool it within 2 hours, and refrigerate up to 4 days. Add a splash of cream when reheating to bring back the silky texture.
