I’ll admit it, I was skeptical about making chicken tikka masala in a slow cooker. The traditional method involves marinating chicken, grilling it in a tandoor, then simmering it in that gorgeous orange-red sauce. But after countless experiments in my kitchen, I’ve figured out how to get those same bold flavors using just a slow cooker and some smart shortcuts.
The beauty of this kosher version is that we skip the yogurt marinade (since we can’t mix dairy with meat) and instead rely on a spice paste that does double duty. It seasons the chicken beautifully and creates the base for our sauce. I use coconut milk instead of heavy cream, which actually works better than you’d think. The coconut adds richness without competing with the warming spices like garam masala, cumin, and paprika.
Why Coconut Milk Works Better Than Cream
What makes this recipe work is the timing. You can’t just throw everything in the slow cooker at once and expect restaurant-quality results. I brown the chicken first for better texture, then build the sauce separately before combining everything. The slow cooker does the rest of the work, but those initial steps make all the difference. After six hours on low, you’ll have tender chicken in a sauce that’s thick enough to coat rice but not so heavy that you feel sluggish after dinner.
The Secret to Perfect Slow Cooker Tikka Masala
This is perfect for busy weeknights when you want something special without the fuss. Serve it over basmati rice with some warm naan on the side, and don’t forget a simple cucumber salad to cut through the richness. The leftovers are even better the next day once all those spices have had more time to meld together.

Ingredients
Method
- Season the chicken pieces with salt and pepper. Heat vegetable oil in a large skillet over medium-high heat.
- Brown the chicken pieces in batches, about 3-4 minutes per side. Don't overcrowd the pan. Transfer browned chicken to the slow cooker.
- In the same skillet, add 2 tablespoons oil and the diced onion. Cook for 5 minutes until softened.
- Add garlic, ginger, and tomato paste. Cook for 1 minute until fragrant.
- Add all the spices (garam masala through cayenne) and cook for 30 seconds, stirring constantly to prevent burning.
- Pour the crushed tomatoes and coconut milk into the slow cooker with the chicken.
- Add the spice mixture from the skillet, brown sugar, and salt. Stir to combine everything well.
- Cover and cook on LOW for 6 hours or HIGH for 3 hours, until chicken is tender and sauce has thickened.
- Taste and adjust seasoning with salt, pepper, or cayenne as needed.
- Serve over basmati rice and garnish with fresh cilantro.
