Slow Cooker Butter Chicken: Creamy 15-Minute Prep

If you love the restaurant-style butter chicken from our classic butter chicken recipe but want it without standing over the stove, this slow cooker butter chicken is for you. Juicy chicken thighs soak up a spiced tomato gravy for hours while you go about your day — then a swirl of cream and butter at the end turns it silky and rich. Fifteen minutes of hands-on prep is all it takes, and the slow cooker does the rest.

Why You’ll Love This Slow Cooker Butter Chicken

• 15 minutes of prep, then hands-off — dump, cover, and walk away for 6–8 hours.
• Thighs, never breasts — chicken thighs stay succulent after hours of gentle cooking; breasts dry out (the one trick the best slow-cooker recipes get right).
• Restaurant-creamy finish — the cream and butter go in at the END, so the gravy turns velvety instead of splitting.
• Dairy-free option included — swap in coconut milk and skip the butter for a rich coconut-butter chicken.
• Freezer-friendly — make a double batch; it reheats like a dream.

Slow Cooker Butter Chicken Ingredients

For the Spiced Tomato Sauce

• 1 can (15 oz / 425g) tomato sauce
• 2 tablespoons tomato paste (for depth and color)
• 1 large yellow onion, finely chopped
• 4 garlic cloves, minced
• 1 tablespoon fresh ginger, grated
• 2 tablespoons garam masala
• 2 teaspoons ground cumin
• 2 teaspoons ground coriander
• 1 teaspoon turmeric powder
• 1 teaspoon Kashmiri red chili powder (mild) or smoked paprika
• 1 tablespoon sugar (balances the tomatoes — use honey for a natural option)
• 1½ teaspoons salt, or to taste
• ½ cup water or low-sodium chicken broth

For the Chicken

• 2 lbs (900g) boneless, skinless chicken thighs, cut into 1½-inch pieces
• 3 tablespoons butter, cut into small cubes

For the Creamy Finish

• ¾ cup heavy cream, at room temperature
• 1 teaspoon kasuri methi (dried fenugreek leaves), crushed between your palms
• Fresh cilantro, chopped (for garnish)

How to Make Slow Cooker Butter Chicken

Step 1: Mix the Sauce

Add the tomato sauce, tomato paste, onion, garlic, ginger, garam masala, cumin, coriander, turmeric, Kashmiri red chili powder, sugar, salt, and water to the slow cooker. Stir until everything is well combined and the spices are evenly distributed.

Step 2: Add the Chicken

Nestle the chicken thigh pieces into the sauce, turning them so every piece is coated. Scatter the cubed butter over the top. Don’t worry if the chicken isn’t fully submerged — it will cook down into the sauce.

Step 3: Slow Cook

Cover and cook on LOW for 6–8 hours or on HIGH for 3–4 hours, until the chicken is fork-tender and shreds easily (165°F / 74°C internal temperature). Low and slow gives the most succulent result; high works when you’re short on time.

Step 4: Stir in the Butter and Kasuri Methi

Turn the slow cooker to HIGH (or keep on LOW if already there). Stir in the crushed kasuri methi and let it steep for 5 minutes so its aroma blooms in the hot gravy.

Step 5: Add the Cream (at the End — Never Earlier)

Pour in the room-temperature heavy cream and stir gently until the gravy turns smooth and velvety. Cook uncovered for 15–20 more minutes so the sauce thickens slightly. Taste and adjust salt.

Step 6: Serve

Spoon over fluffy basmati rice or serve with warm naan bread for scooping. Garnish with fresh cilantro and an extra drizzle of cream.

Tips for the Best Slow Cooker Butter Chicken

• Thighs are non-negotiable. Chicken breast turns chalky after 6+ hours in a slow cooker — thighs stay juicy and tender. This is the single biggest difference between a great slow-cooker butter chicken and a mediocre one.
• Cream goes in LAST. Dairy added at the start can split and curdle over long cooking. Stirring it in at the end (brought to room temperature first) keeps the gravy silky.
• Don’t lift the lid. Every peek adds 15–20 minutes of cooking time. Trust the timer.
• Want it healthier? Use light cream or the coconut-milk option below, cut the butter to 2 tablespoons, and serve over cauliflower rice or brown basmati rice. If you enjoy lighter slow-cooker curries, you’ll also love our slow cooker chicken curry.
• Dairy-free coconut version: Replace the butter with 2 tablespoons coconut oil and the heavy cream with 1 cup full-fat coconut milk (added at the same final step). Rich, creamy, completely dairy-free.
• Short on time? A jar-sauce shortcut works: Use 1 jar (15 oz) of store-bought butter chicken simmer sauce in place of the tomato sauce, tomato paste, onion, garlic, ginger, and spices — just add the sugar and salt to taste. Homemade tastes better, but the shortcut beats takeout.

What to Serve with Slow Cooker Butter Chicken

Butter chicken was made for scooping. Serve it with warm naan bread (garlic naan is best), fluffy basmati rice, or jeera rice to catch every drop of gravy. For a fresh contrast, add a simple kachumber salad or a cooling cucumber raita on the side.

Storage and Reheating

• Refrigerator: Store in an airtight container for up to 4 days. The gravy tastes even better the next day as the spices meld.
• Freezer: Freeze (before adding the cream is ideal) for up to 3 months. Stir in the cream after thawing and reheating. Already finished leftovers also freeze fine.
• Reheating: Warm gently on the stovetop over low heat or in the microwave at 50% power, stirring halfway. Add a splash of water or cream if the sauce thickened. Avoid boiling — high heat can split the cream.

Slow Cooker Butter Chicken FAQs

Can I use chicken breast instead of thighs?
You can, but we don’t recommend it. Breasts dry out and turn stringy after hours in the slow cooker. If you must, use whole breasts and check them at the 3-hour mark on HIGH — pull them as soon as they hit 165°F/74°C.

When do I add the cream — at the beginning or the end?
Always at the end. Cream cooked for 6–8 hours can split or curdle. Stir room-temperature cream in during the last 15–20 minutes for a smooth, velvety gravy.

Can I make dairy-free slow cooker butter chicken?
Yes! Replace the butter with coconut oil and the heavy cream with full-fat coconut milk. Add the coconut milk at the same final step as the cream. It’s just as rich and completely dairy-free.

How long does slow cooker butter chicken take?
LOW for 6–8 hours or HIGH for 3–4 hours. LOW gives more tender chicken and deeper flavor; HIGH works fine when you’re short on time. Don’t go longer than 8 hours on LOW or the chicken can get mushy.

Can I make this with jar sauce?
Yes — a jar of butter chicken simmer sauce is a fine shortcut. Add the chicken, butter, sugar, and salt, slow cook as directed, and finish with the cream and kasuri methi. Homemade sauce still wins on flavor, but the shortcut is solid for busy weeks.
