Slow Cooker Butter Chicken tastes like a Saturday-night treat: tender chicken thighs bathed in a velvety tomato sauce that's rich with butter, a whisper of garam masala, and just enough cream to make every spoonful feel luxurious. The sauce clings to the chicken in that glossy, sunset-orange way you want, and the whole house smells like toasted spices by the time you lift the lid.

The magic here is that the slow cooker does the babysitting. You bloom the spices for a minute on the stove so they don't taste raw, then everything goes in the pot and you walk away. Six hours later you stir in cream and butter, and dinner is done.
I keep the ingredient list honest: pantry spices, canned tomato puree, and chicken thighs that stay juicy even after a long cook. No specialty runs, no complicated marinade.
Why You'll Love This Recipe
About the Ingredients
2 lb (900g) boneless, skinless chicken thighs, cut into 1 1/2-inch pieces
Thighs stay juicy in a slow cooker far better than breast. If you only have breast, cut it larger and add it in the last 90 minutes so it doesn't dry out.
1 cup (240g) plain full-fat yogurt
Full-fat yogurt keeps the sauce creamy and won't split. Greek yogurt works but is tangier, so add an extra teaspoon of honey if you go that route.
2 tbsp (30g) unsalted butter, plus 2 tbsp (30g) for finishing
Use real butter, not margarine, for that round, rich flavor. Salted butter is fine; just taste before adding extra salt at the end.
1 medium yellow onion (about 1 cup / 160g), finely diced
Yellow onion gives the sweetest base. Frozen diced onion (about 1 cup) is a fine shortcut on busy mornings.
3 cloves garlic, minced (about 1 tbsp)
Fresh garlic is best, but jarred minced garlic works in a pinch; use 1 tablespoon and add it with the spices.
1 tbsp fresh ginger, grated
Frozen grated ginger or ginger paste from a tube measures the same and saves time. Look for it near the produce or freezer aisle.
2 tsp garam masala, plus 1/2 tsp for finishing
If you don't have garam masala, swap in 1 1/2 tsp curry powder plus a pinch of cinnamon. Buy a fresh jar; stale spice tastes dusty.
1 tsp ground cumin and 1 tsp smoked paprika
Smoked paprika adds a subtle warmth; regular paprika works. Cumin is the backbone here, so use a jar you've opened recently.
1 can (15 oz / 425g) tomato puree
Tomato puree gives a smooth sauce; crushed tomatoes work but will be chunkier. Avoid ketchup or pasta sauce, which add sugar.
1/2 cup (120ml) heavy cream
Add cream at the very end so it stays fresh and doesn't curdle. Coconut cream is a good dairy-free swap; use the thick top layer.
1 1/2 tsp kosher salt, plus more to taste
Kosher salt is less salty by volume than table salt. If using table salt, start with 1 teaspoon and adjust at the end.
2 tbsp chopped fresh cilantro, for serving
Flat-leaf parsley is a fine substitute if you don't like cilantro. Skip it if you're out; the dish is still delicious.
Tips & Tricks
Don't Skip the Bloom
Toasting the spices in butter for 60 seconds before they hit the slow cooker wakes up their flavor; raw spices taste flat after six hours.
Keep the Cream for Last
Stirring cream in at the end keeps the sauce bright and prevents it from separating during the long cook.
Thicken Without Guessing
If the sauce looks thin, leave the lid off on High for 20-30 minutes, stirring once, until it coats the back of a spoon.
Pro Tips
Step-by-Step Instructions
1. Bloom the Spices
Melt 2 tablespoons butter in a skillet over medium heat (350°F / 175°C) for 1 minute until foaming, then add the onion and cook 4-5 minutes until soft and golden at the edges. Stir in garlic, ginger, garam masala, cumin, and paprika and cook 60 seconds until fragrant and bubbling at the edges; don't let them brown.
2. Whisk the Yogurt Base
In a bowl, whisk the yogurt with the tomato puree and 1 1/2 teaspoons salt until smooth. Scrape in the onion-spice mixture and stir until evenly combined and glossy.
3. Load the Slow Cooker
Add the chicken pieces to the slow cooker and pour the sauce over them, stirring so every piece is coated. The chicken should be mostly submerged; if not, add 2 tablespoons water.
4. Cook Low and Slow
Cover and cook on Low for 5 to 6 hours (or High for 3 to 3 1/2 hours) until the chicken is fork-tender and reaches 165°F (74°C) on an instant-read thermometer. The sauce should look darker and slightly thickened at the edges.
5. Finish with Cream
Turn the cooker off and stir in the cream, remaining 2 tablespoons butter, and 1/2 teaspoon garam masala. Let it sit uncovered 5 minutes until the sauce turns pale orange and silky.
6. Taste and Serve
Taste and add salt if needed, then scatter with cilantro. Serve hot over basmati rice or with warm naan for scooping.
Delicious Variations
Coconut Butter Chicken
Swap the heavy cream for full-fat coconut cream and use coconut oil instead of the finishing butter for a dairy-free version.
Extra-Veggie Butter Chicken
Add 2 cups of cauliflower florets or cubed sweet potato in the last hour of cooking for a one-pot meal.
Spicier Butter Chicken
Stir in 1/2 teaspoon cayenne or one chopped green chili with the spices for a gentle kick.
How to Store Slow Cooker Butter Chicken
Refrigerator
Store in an airtight container in the refrigerator for up to 4 days; the flavors deepen overnight.
Freezer
Freeze in portions for up to 3 months. Leave out the cream if freezing, then stir it in after reheating for the freshest taste.
Reheating
Reheat gently on the stovetop over medium-low heat (about 300°F / 150°C) for 5-7 minutes, stirring, until steaming but not boiling, or microwave in 1-minute bursts.
Frequently Asked Questions
Q: Can I use chicken breast instead of thighs in butter chicken?
Yes, but add it later so it doesn't dry out. Cut the breast into large chunks and stir it in during the last 90 minutes on Low, cooking until it reaches 165°F (74°C).
Q: Why did my slow cooker butter chicken curdle?
The yogurt likely split from cooking too hot or too long. Use full-fat yogurt, whisk it with the tomato puree before adding, and stir in the cream only after the cooker is off.
Q: How do I thicken butter chicken sauce?
Leave the lid off on High for 20-30 minutes, stirring occasionally, until the sauce coats a spoon. You can also mash a few pieces of chicken into the sauce to help it thicken.
Q: Can I make slow cooker butter chicken dairy-free?
Yes. Use coconut cream instead of heavy cream, coconut oil instead of butter, and a plain dairy-free yogurt such as coconut or almond yogurt. The sauce will be slightly less rich but still delicious.
Q: How long does butter chicken last in the fridge?
About 4 days in an airtight container. Reheat gently on the stovetop or in the microwave until steaming, and add a splash of water if the sauce has thickened too much.
