Slow Cooker Butter Chicken

Fall-apart tender chicken thighs in a rich, velvety tomato sauce scented with garam masala, ginger and garlic: this slow cooker butter chicken tastes like a restaurant favorite, and the slow cooker does almost all of the work.

Chicken thighs simmer for hours in a base of tomato sauce, onion and warm spices until they are tender enough to shred with a fork. Yogurt, heavy cream and butter go in at the very end and melt into the sauce, so it turns silky, creamy and gently rich without a trace of heaviness.

The detail that makes the biggest difference is adding the dairy at the end instead of at the start. Yogurt and cream can curdle during a long cook, and stirring them in for the last 15 minutes keeps the sauce smooth, glossy and creamy from the first spoonful to the last.

This recipe serves four and takes about 15 minutes of work. Serve it over basmati rice or with warm naan, and you have a full dinner that makes your whole kitchen smell wonderful.

Why You’ll Love This Slow Cooker Butter Chicken

The slow cooker does the work. You stir a sauce together, add the chicken and walk away. There is no browning and no stirring for hours.

The sauce is creamy and mildly spiced. Tomato, garam masala and butter give you a warm, rounded flavor that is rich without being hot, so the whole table can enjoy it.

It tastes even better the next day. The spices keep melding in the refrigerator, which makes this a great choice for meal prep and leftovers.

You control the heat. The recipe is mild as written, and a little cayenne or a diced chili makes it as fiery as you like.

Perfect For

This butter chicken suits busy weeknights, because you can set it up in the morning and come home to dinner. It is also a good choice for meal prep, for feeding a crowd and for cold evenings when you want something warm and comforting.

Since the sauce is mild and creamy, it is easy to serve to a table of different tastes, with extra cayenne or fresh chili on the side for anyone who wants more heat.

Before You Start

Use boneless, skinless chicken thighs. Thighs stay juicy during a long cook, while chicken breasts dry out. Trim off any large pieces of fat.

Thaw the chicken completely. Frozen chicken stays in the unsafe temperature range for too long in a slow cooker, so thaw it in the refrigerator first.

Use full-fat yogurt and heavy cream. They keep the sauce thick and creamy. Low-fat yogurt can make it watery and more likely to separate.

Choose a 4- to 6-quart slow cooker. This amount of chicken and sauce fits comfortably, and the sauce stays deep enough to cover the chicken.

What Makes This Slow Cooker Butter Chicken Work

Chicken Thighs for Tender Meat

Thighs have more fat and connective tissue than breasts, and both melt into the sauce over several hours. The result is meat that shreds with a fork and stays moist instead of turning stringy.

A Tomato and Spice Base

Tomato sauce, a little tomato paste, onion, garlic and ginger form the base, and garam masala, turmeric, cumin and paprika add warmth and color. The tomato paste adds depth and body, so the sauce tastes like it simmered much longer.

Dairy at the End

Yogurt, cream and butter go in after the chicken is cooked. This keeps them from splitting under a long cook and gives the sauce its signature silky, buttery finish.

The Right Finish

Shredding the chicken slightly lets the pieces soak up the sauce, and the last 15 minutes give the dairy time to blend in completely and the sauce time to thicken.

Ingredients for Slow Cooker Butter Chicken

For the Slow Cooker

• 1½ pounds (680 g) boneless, skinless chicken thighs, trimmed
• 1 cup (225 g) tomato sauce
• 2 tablespoons (33 g) tomato paste
• 1 medium onion (110 g), finely chopped
• 3 garlic cloves, minced
• 1 tablespoon (6 g) fresh ginger, grated
• 1 tablespoon garam masala
• 1 teaspoon ground turmeric
• 1 teaspoon ground cumin
• 1 teaspoon paprika
• ½ teaspoon cayenne pepper, optional
• ¾ teaspoon salt, plus more to taste

To Finish

• 1 cup (245 g) full-fat plain yogurt
• ½ cup (120 ml) heavy cream
• 2 tablespoons (28 g) unsalted butter

For Serving

• 2 tablespoons chopped fresh cilantro
• Cooked basmati rice or warm naan

Ingredient Notes and Substitutions

Chicken: Boneless, skinless thighs give the best texture. Chicken breasts also work, but they dry out easily, so cook them for a shorter time (see the variations below).

Yogurt: Full-fat plain yogurt makes the sauce creamy. Greek yogurt works too and makes the sauce a little thicker and tangier. Low-fat yogurt can make the sauce watery.

Tomato sauce and paste: Plain canned tomato sauce works well. Choose one without added herbs or sugar. If you only have crushed tomatoes, use the same amount and blend the sauce smooth before adding the cream.

Garam masala: This warm spice blend is the heart of the flavor, so do not skip it. Brands vary in strength, so taste the sauce at the end and add a pinch more if you like.

Heavy cream: It adds richness and silkiness. Full-fat canned coconut milk is a good dairy-free substitute.

Butter: Butter gives the sauce its name and its shine. Ghee works well too and adds a slightly nuttier flavor.

Heat: The cayenne is optional. For a spicier sauce, add extra cayenne or a finely diced fresh chili, and for a milder one, leave it out.

Kitchen Equipment Needed

• 4- to 6-quart slow cooker
• Cutting board and sharp knife
• Box grater or microplane – for the ginger
• Measuring cups and spoons
• Spoon and whisk
• 2 forks – for shredding the chicken

How to Make Slow Cooker Butter Chicken

Step 1: Mix the Sauce

Add the tomato sauce, tomato paste, onion, garlic, ginger, garam masala, turmeric, cumin, paprika, cayenne, if using, and salt to the slow cooker. Stir until the tomato paste and spices dissolve into a smooth sauce.

Step 2: Add the Chicken

Add the chicken thighs and stir to coat each piece. Nestle them into the sauce in an even layer.

Step 3: Cook

Cover and cook on low for 6 hours or on high for 3 hours, until the chicken is very tender and reaches at least 165°F (74°C). Try to keep the lid closed while it cooks.

Step 4: Shred the Chicken

Use two forks to break the chicken into large, bite-size pieces directly in the slow cooker. It should fall apart easily.

Step 5: Add the Yogurt, Cream and Butter

Whisk the yogurt in a small bowl with a ladle of hot sauce to warm it, then stir it into the slow cooker along with the cream and butter. Cover and cook on high for 15 minutes, until the butter melts and the sauce is hot and creamy. Do not let it boil.

Step 6: Taste and Serve

Taste the sauce and add more salt if needed. Garnish with the cilantro and serve over basmati rice or with warm naan.

How to Know It’s Done

Butter chicken is done in the slow cooker when the chicken falls apart and the sauce is creamy. Use these signs to check.

What to Check	Ready When
Chicken	Falls apart easily when pressed with a fork
Temperature	At least 165°F (74°C) in the thickest piece
Sauce	Thick enough to coat the back of a spoon, deep orange-red
Dairy	Fully blended into the sauce, with no streaks or curdled bits
Flavor	Balanced and well seasoned, with no raw spice taste

If the chicken is not tender after the recommended time, cover it and cook for another 30 to 60 minutes. If the sauce is too thin, remove the lid and cook on high for 10 to 15 minutes.

Tips for the Best Slow Cooker Butter Chicken

Trim the fat. Thighs have large pieces of fat that can leave an oily layer on top. Trim them before cooking, and skim off any extra oil before serving.

Keep the lid on. Every time you lift the lid, heat escapes and the cooking time grows by 15 to 20 minutes.

Warm the yogurt first. Whisking the yogurt with a ladle of hot sauce before stirring it in helps it blend smoothly instead of splitting.

Taste at the end. Salt, spices and acidity change during cooking. If the sauce tastes sharp from the tomato, add a small pinch of sugar, and if it tastes flat, add a little more salt.

Double the sauce for extra rice. If you love lots of sauce, double the tomato sauce, yogurt and cream, and use a larger slow cooker.

Common Mistakes and How to Fix Them

Adding the dairy at the start. Yogurt and cream can curdle during a long cook. How to fix it: stir them in during the last 15 minutes, and warm the yogurt with a ladle of hot sauce first.

Using chicken breasts for the full time. Breast meat turns dry and stringy after hours in the slow cooker. How to fix it: use thighs, or cook breasts for a shorter time and check the temperature.

Skipping the final taste. The sauce can taste flat if it is under-seasoned. How to fix it: taste at the end and add salt a pinch at a time, or a little more garam masala.

Lifting the lid too often. Each peek lets heat out and slows the cooking. How to fix it: keep the lid closed, and only check at the end of the cooking time.

Ending with a thin sauce. Chicken and tomato release liquid as they cook. How to fix it: remove the lid and cook on high for 10 to 15 minutes, until the sauce coats the back of a spoon.

Variations

Dairy-Free Butter Chicken

Replace the yogurt with unsweetened coconut yogurt, the cream with full-fat canned coconut milk and the butter with a dairy-free butter.

Spicy Butter Chicken

Add 1 teaspoon of cayenne, or a finely diced green chili, to the sauce at the start. Serve extra chili on the side for anyone who likes more heat.

Chicken Breast Version

Use boneless, skinless chicken breasts and cook them on low for 3 to 4 hours, or on high for 1½ to 2 hours, until they reach 165°F (74°C). Shred them, then finish with the dairy as usual.

Deeper-Flavor Butter Chicken

Before adding anything to the slow cooker, cook the onion, garlic, ginger and spices in the 2 tablespoons of butter in a skillet for 3 to 4 minutes, until fragrant. Scrape them into the slow cooker with the tomato sauce and tomato paste, add the chicken and cook as directed. At the end, stir in the yogurt and cream and skip the butter, since it is already in the sauce.

Serving Suggestions

Serve your butter chicken over fluffy basmati rice, or with warm homemade naan for scooping up every drop of sauce. Add a spoonful of cucumber salad or some quick pickled red onions for a fresh, tangy contrast to the rich sauce, and finish with fresh cilantro and a squeeze of lemon.

Storage and Reheating

Refrigerator: keep leftovers in an airtight container in the refrigerator for up to 3 days. The sauce thickens as it cools.

Reheating: reheat on the stove over low heat with a splash of water or cream to loosen the sauce, stirring often. You can also reheat single portions in the microwave.

Freezing: freeze in airtight containers for up to 3 months. Thaw overnight in the refrigerator, then reheat gently on the stove. The sauce can look slightly separated after thawing, and a good stir brings it back together.

Frequently Asked Questions

Can I use chicken breasts?

Yes, but they cook faster and dry out more easily. Cook them on low for 3 to 4 hours, or on high for 1½ to 2 hours, until they reach 165°F (74°C), then shred them and finish with the dairy.

Can I freeze butter chicken?

Yes. Freeze it in airtight containers for up to 3 months. Thaw it overnight in the refrigerator and reheat it gently on the stove, adding a splash of cream or water if the sauce is too thick.

Can I skip the garam masala?

You can, but the sauce will taste much less rounded. Garam masala is the main warm spice in this recipe. If you do not have it, try a mix of ½ teaspoon of ground cumin, ½ teaspoon of ground coriander and a pinch of cinnamon.

Can I make it dairy-free?

Yes. Use coconut yogurt, full-fat canned coconut milk and a dairy-free butter. The sauce will have a slight coconut flavor.

Is this butter chicken spicy?

It is mild as written, and the cayenne is optional. Add more cayenne, or a fresh chili, for a spicier sauce.

Can I cook frozen chicken thighs in the slow cooker?

It is better to thaw them first. Frozen chicken takes too long to heat up in a slow cooker, which keeps it in the unsafe temperature range for longer.

Why is my sauce thin?

Chicken and tomato release liquid during cooking. Remove the lid and cook the sauce on high for 10 to 15 minutes, until it thickens, or add a spoonful of tomato paste.

Final Thoughts

Good slow cooker butter chicken comes down to three things: tender chicken thighs, a spiced tomato base and dairy stirred in at the end for a silky finish.

Once you have the base down, you can make it as mild or as spicy as you like and keep a batch in the refrigerator for easy dinners all week.
