Creamy Slow Cooker Butter Chicken (Better Than Takeout)
This slow cooker butter chicken delivers all the rich, velvety goodness of your favorite Indian takeout with barely any hands-on time. The steady low heat turns the chicken into spoon tender shreds while you go about your day.
Toss everything into the slow cooker, walk away, and come back to a deeply spiced tomato cream sauce that clings to every bite. Pile it over rice, and dinner is done.
Why This Butter Chicken Wins Weeknights
I have made butter chicken more times than I can count, and this slow cooker version is the one I reach for when life gets busy. Skipping the stovetop sear and the yogurt marinade means there is almost no prep to worry about.
The sauce still tastes layered and complex, with warm spice notes that mellow as it cooks. The chicken stays incredibly moist and falls apart under a fork.
Adding the cream and butter right at the end keeps the sauce tasting fresh and glossy, never heavy or broken. It is that restaurant finish with almost zero fuss.
Ingredients
- 1.5 lbs boneless skinless chicken thighs: trimmed of excess fat for a cleaner sauce
- 1 medium yellow onion: finely chopped so it melts into the sauce
- 3 garlic cloves: minced
- 1 tablespoon grated fresh ginger: use the fine side of a box grater, peel and all
- 1 (14 oz) can tomato passata: or plain crushed tomatoes
- 1/2 cup heavy cream: full fat for the silkiest texture
- 3 tablespoons unsalted butter: cut into pieces so it melts fast
- 1 tablespoon garam masala: the warm spice backbone
- 1 teaspoon ground cumin
- 1 teaspoon ground coriander
- 1/2 teaspoon ground turmeric: for that deep golden color
- 1/2 teaspoon chili powder: adjust to your heat preference
- 1 teaspoon salt: plus more to taste
- 1 teaspoon sugar: balances the acidity of the tomatoes
- 1 tablespoon cornstarch mixed with 2 tablespoons cold water: optional, for a thicker sauce
Variations and Substitutions
- Chicken breasts: Use boneless skinless breasts and check them at 2 to 3 hours on low. They cook faster and can dry out if left too long.
- Dairy free: Swap the heavy cream for full fat coconut cream and use a vegan butter or ghee alternative. The coconut adds a subtle sweetness that pairs well with the spices.
- Extra heat: Double the chili powder or stir in a minced fresh serrano or Thai chili with the aromatics.
- Herb it up: Stir a handful of chopped fresh cilantro into the sauce just before serving, or try a sprinkle of dried fenugreek leaves for a more traditional note.
- Not a fan of garam masala: A good quality curry powder will work in a pinch, though the flavor will be a little different.
If you love the idea of a hands off meal but want something faster, our Quick Chicken Tikka Masala comes together in under 30 minutes on the stovetop.
How to Make Slow Cooker Butter Chicken
Step 1: Build the Sauce and Load the Chicken
In your slow cooker, whisk together the 14 ounces of tomato passata, 1 tablespoon garam masala, 1 teaspoon cumin, 1 teaspoon coriander, 1/2 teaspoon turmeric, 1/2 teaspoon chili powder, 1 teaspoon salt, and 1 teaspoon sugar until smooth. Stir in the chopped onion, 3 minced garlic cloves, and 1 tablespoon grated ginger. Add the chicken thighs and spoon some of the sauce over the top so they are mostly submerged. Cover and cook on low for 4 to 6 hours, or on high for 2 to 3 hours, until the chicken is fork tender.
At first the sauce will look a little thin and the spices not fully melded, but trust the process. A few hours later the kitchen will smell warm and inviting, and the meat will surrender easily when you poke it.
Step 2: Shred the Cooked Chicken
Turn off the slow cooker. Carefully lift the chicken thighs out onto a cutting board and let them rest for a couple minutes so you can handle them. Use two forks to shred the meat into bite sized pieces. It should pull apart with almost no pressure.
If you prefer larger chunks, you can cut them with a knife instead. Shredded chicken soaks up more sauce, so I lean that way, but both textures work beautifully.
Step 3: Finish with Cream and Butter
Set the slow cooker to high if it was on low, and bring the sauce to a gentle simmer. Stir in the 1/2 cup heavy cream and 3 tablespoons of butter, letting them melt completely into the sauce. If you like a thicker gravy, whisk in the cornstarch slurry now and cook for about 5 minutes, until the sauce coats the back of a spoon.
This is the step where the sauce transforms into that signature velvety butter chicken consistency. Give it a taste and adjust the salt or chili at this point; a tiny squeeze of lemon juice can also brighten everything up.
Step 4: Spoon Over Rice and Garnish
Return the shredded chicken to the sauce and toss to coat every strand. Spoon generous portions over steamed basmati rice, scatter fresh cilantro on top, and serve right away with warm naan on the side.
The sauce will be glossy and deep orange-red. Leftovers only get better in the fridge, but do not be surprised if there is nothing left to store.
Tips for the Tenderest Chicken
- Do not lift the lid during cooking. Every peek releases heat and adds time to the cook.
- Use full fat heavy cream and real butter. Low fat substitutes can make the sauce thin or grainy when heated.
- If the sauce tastes a little flat, a pinch more salt or a squeeze of lemon juice at the end will make the spices pop.
- For an ultra smooth sauce, blend the tomato mixture with an immersion blender before adding the chicken, or blend the sauce after cooking and before you add the cream.
- This recipe is mild as written. Double the chili powder or add a fresh chopped chili with the aromatics if you want real kick.
Cook times by setting:
| Slow Cooker Setting | Cook Time |
|---|---|
| Low | 4 to 6 hours |
| High | 2 to 3 hours |
Storing Leftover Butter Chicken
Refrigerate leftovers in an airtight container for up to 4 days. The flavors deepen overnight, so it might taste even better the next day. Reheat gently on the stovetop over medium low heat, adding a splash of water or milk if the sauce has thickened too much. You can also microwave it in short bursts, stirring between each.
What to Serve with Slow Cooker Butter Chicken
A pile of fluffy steamed basmati rice is classic and soaks up every bit of sauce. Warm naan bread is just as good for scooping. A simple cucumber and red onion salad dressed with lime juice cuts through the richness perfectly, while a handful of roasted cashews scattered on top adds a nice crunch.
Frequently Asked Questions
Can I use chicken breasts instead of thighs?
Yes, but they cook faster and can dry out. Use boneless skinless breasts and check them at 2 to 3 hours on low. They are done when they reach 165°F and shred easily.
How do I make this in an Instant Pot?
Use the sauté function to cook the onion, garlic, and ginger in a little oil for 5 minutes, then add the tomato passata and spices. Add the chicken, seal the lid, and pressure cook on high for 10 minutes with a natural release. Proceed with the cream and butter steps as written.
What if I only have crushed tomatoes?
They work just as well, but you may want to blend the sauce with an immersion blender after cooking for a silkier texture, since crushed tomatoes have more pieces than passata.
Is there a way to make it less spicy?
Sure. Omit the chili powder entirely and stick with the garam masala and turmeric. The dish will be aromatic and warming without any heat.
