Garlic Butter Makhani Chicken Thighs: Slow Cooker Step-by-step instructions

Before you start

Before you start, make sure you have a 6-quart slow cooker and all the ingredients measured and ready. The spiced tomato puree can be store-bought or homemade; if using plain puree, stir in the extra spices. Grate the ginger and mince the garlic so they’re ready to sprinkle.

Cut the garlic herb butter into small medallions so they’ll melt evenly. Have the chicken thighs thawed if frozen—there’s no need to brown them first. This recipe is truly dump-and-go, so the only prep is chopping and measuring, which takes about ten minutes.

Instructions

Layer and Walk Away

1. 1Layer the Ingredients
   Place the chicken thighs in an even layer in the bottom of a 6-quart slow cooker. Pour the spiced tomato puree over the chicken, then sprinkle with the grated ginger and minced garlic. Dollop the Greek yogurt over the top, then place the garlic herb butter medallions evenly across the surface. Do not stir.
   Look for The chicken is covered with the tomato mixture, with yogurt and butter visible on top.
   Tip Keeping the butter on top allows it to melt down through the sauce as it cooks.
2. 2Cook Low and Slow
   Cover the slow cooker and cook on LOW for 4 to 5 hours, or on HIGH for 2 1/2 to 3 hours, until the chicken is tender and cooked through. The sauce will be bubbling gently around the edges.
   Look for The sauce is simmering and the chicken is fork-tender.
   Safe temperature 165°F (74°C) internal temperature (poultry)
   Tip Resist lifting the lid during cooking—each peek adds 15-20 minutes of cook time.

At the end of this phase, the slow cooker is filled with raw chicken, tomato puree, ginger, garlic, yogurt, and butter. The ingredients are layered but not mixed—the butter sits on top, ready to melt.

The aroma is fresh and spicy, with the promise of what’s to come. Before moving on, make sure the lid is secure and the cooker is set to the right temperature.

Simmer to Tender

3. 3Shred or Leave Whole
   Once the chicken is cooked through, use two forks to shred the thighs directly in the slow cooker, or leave them whole for a heartier presentation. Stir the sauce gently to combine the yogurt and butter into a silky curry.
   Look for The sauce turns smooth and orange-red as you stir.
   Tip For whole thighs, use tongs to transfer them to a plate, then stir the sauce before returning them.
4. 4Let the Sauce Thicken
   If the sauce seems thin, leave the slow cooker on LOW with the lid off for 10-15 minutes to let it reduce slightly. Stir occasionally. The sauce should coat the back of a spoon.
   Look for The sauce clings to a spoon and has a glossy sheen.
   Tip Do not over-reduce—the sauce will thicken more as it cools.

After 4 to 5 hours on LOW, the sauce is bubbling and the chicken is fork-tender. The yogurt and butter have melted into the tomato, creating a glossy, orange-red sauce. The kitchen smells richly spiced and buttery. The chicken should reach 165°F (74°C) and shred easily. Stir gently to combine, and if the sauce is thin, let it reduce with the lid off.

Serve and Savor

5. 5Serve Over Rice
   Spoon the hot curry over steamed basmati rice and serve with warm garlic naan on the side. Ladle extra sauce over the top so every bite is coated.
   Look for The curry is steaming and fragrant.
   Tip Warm the naan in the oven or a dry skillet before serving.

The curry is ready to serve: tender chicken pieces or shreds coated in a velvety, aromatic sauce. The texture is smooth and creamy, with visible flecks of herbs from the butter. The flavor is balanced—tangy from yogurt, sweet from tomato, savory from garlic and butter. Spoon it over rice, tear off a piece of naan, and enjoy the payoff of a hands-off meal.

Common mistakes

The most common mistake is lifting the lid too often. Each peek releases heat and adds cooking time, so trust the process and let the slow cooker do its job. Another pitfall is using chicken breasts instead of thighs—breasts dry out and become stringy. Stick with thighs for the best texture.

If the sauce curdles, it’s usually because the yogurt was added while the pot was too hot, or the yogurt was non-fat. To avoid this, let the yogurt come to room temperature and stir it in gently at the end, rather than dumping it in at the start. Finally, don’t skip the butter—it’s what makes the sauce silky.

How to tell it’s done

The chicken is done when it reaches an internal temperature of 165°F (74°C) on an instant-read thermometer. The meat should be fork-tender and easily shredded, and the sauce should be bubbling gently around the edges.

If you’re unsure, give the pot a gentle stir—the chicken should break apart with minimal effort. The sauce will look slightly thin while hot but will thicken as it cools. Taste and adjust salt if needed, keeping in mind that the butter and yogurt add their own seasoning.
