Garlic Butter Tikka Masala Lamb Cubes: Slow Cooker Step-by-step instructions

Before you start

Before starting, ensure the lamb shoulder is cut into uniform 1-inch cubes for even cooking. Measure out the tikka masala sauce, garam masala, garlic herb butter, and Greek yogurt so everything is ready to layer.

Have your slow cooker plugged in and the insert in place. No need to preheat or brown anything—this recipe is truly dump-and-go.

Instructions

Layer and Set

1. 1Layer the Ingredients
   Place the cubed lamb shoulder in the bottom of the slow cooker insert. Pour the tikka masala sauce over the lamb, then sprinkle with garam masala. Add the garlic herb butter medallions on top, and dollop the Greek yogurt over everything. Do not stir.
   Look for The lamb is covered with sauce and topped with butter and yogurt; the ingredients remain in distinct layers.
   Tip Resist stirring—the slow cooker will blend the flavors as it cooks.

After layering the ingredients, you'll see distinct layers: the lamb at the bottom, sauce covering it, and the butter and yogurt on top. The aroma of garam masala and tomato is fresh and inviting. Everything looks colorful and vibrant. No need to stir—just cover and set the timer.

Slow-Cook

2. 2Slow-Cook the Curry
   Cover the slow cooker with the lid. Cook on LOW for 6 to 8 hours, or on HIGH for 4 to 5 hours, until the lamb is fork-tender and easily pulls apart. The sauce will be bubbling and thickened. Let it rest for 3 minutes before slicing.
   Look for The curry is gently bubbling, the lamb is tender, and the sauce has darkened to a rich crimson.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip Check at the minimum time; slow cookers vary, so adjust time as needed.

During cooking, the slow cooker will be gently bubbling, and the fragrance of spices will fill the kitchen. The sauce will darken to a deep crimson, and the lamb will become tender.

At the end, the curry should be simmering, with the sauce slightly reduced and glossy. The lamb should easily break apart with a fork.

Serve

3. 3Serve and Finish
   Once the lamb is cooked through, let it rest in the sauce for 5 minutes. Serve the curry over steamed basmati rice with warm naan on the side. Ladle the sauce generously over the top.
   Look for The lamb is tender and coated in a velvety, fragrant sauce.
   Tip For extra richness, swirl in a pat of butter before serving.

When ready to serve, the curry is rich and aromatic, with tender lamb cubes coated in a velvety sauce. The garlic butter and yogurt have melded into the sauce, giving it a luxurious sheen. Spoon the curry over rice or alongside naan, and enjoy the satisfying clink of the spoon against the bowl.

Common mistakes

One common mistake is stirring the ingredients before cooking—this can cause the yogurt to curdle. Trust the slow cooker to blend the flavors. Another pitfall is lifting the lid too often, which releases heat and extends cooking time.

Also, avoid using lean lamb; without enough fat, the meat can dry out. Finally, don't rush the cooking; low and slow is essential for tender results.

How to tell it’s done

The curry is done when the lamb is fork-tender and easily shreds apart with a spoon. The sauce should be bubbling gently and slightly thickened.

To be safe, use a meat thermometer: the lamb must reach an internal temperature of 145°F (63°C). Let the meat rest in the sauce for at least 3 minutes before serving to allow the juices to redistribute.
