Crockpot Garlic Butter Spinach Saag Lamb Cubes Step-by-step instructions

Before you start

Before you start, cut the lamb shoulder into 1-inch cubes if not already done. Grate the ginger and mince the garlic. Measure the spinach, yogurt, and cumin. Have the garlic herb butter at room temperature so it's easy to slice. Set out your 6-quart slow cooker and all the ingredients. No other prep is needed—this is truly a dump-and-go meal.

Instructions

Layer the Ingredients

1. 1Layer the Lamb and Greens
   Place the cubed lamb shoulder in the bottom of a 6-quart slow cooker. Sprinkle with kosher salt. Pile the fresh baby spinach on top, followed by the grated ginger, minced garlic, and toasted cumin seeds. Do not stir.
   Look for The lamb is covered with a mound of greens and aromatics.
   Tip Keep the spinach piled high—it will wilt down as it cooks.
2. 2Add the Yogurt and Butter
   Dollop the Greek yogurt over the top of the spinach mixture. Place the garlic herb butter medallions evenly over the surface. Do not stir.
   Look for The top is scattered with yogurt and butter pats.
   Tip The butter melts over everything, infusing the sauce.

At the end of this phase, the slow cooker contains a neat layer of raw lamb at the bottom, covered with a tall pile of spinach, ginger, garlic, and cumin, topped with dollops of yogurt and pats of butter.

The colors are bright—green, white, and golden—and the aroma is fresh and aromatic, with notes of cumin and garlic. Everything is ready to cook without stirring.

Slow Cook Until Tender

3. 3Cook Low and Slow
   Cover the slow cooker and cook on low for 6 to 8 hours, until the lamb is fork-tender. The spinach will wilt into a creamy sauce as it cooks. Do not lift the lid during the first 4 hours. Let it rest for 3 minutes before slicing.
   Look for The sauce is bubbling gently and the lamb shreds easily.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip Low heat is key for melting the lamb's collagen.
4. 4Check the Temperature and Rest
   After 6 hours, check that the lamb has reached an internal temperature of 145°F (63°C) on an instant-read thermometer. Let the meat rest for at least 3 minutes before serving to allow the juices to redistribute.
   Look for The thermometer reads 145°F (63°C) or higher.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip Resting keeps the lamb moist and tender.

After 6 to 8 hours on low, the slow cooker is bubbling gently. The spinach has wilted into a deep green sauce, the yogurt and butter have melded into a creamy base, and the lamb is fork-tender. The kitchen smells richly of garlic, butter, and warm spices. The sauce is thick enough to coat a spoon, and the lamb is just beginning to fall apart.

Finish and Serve

5. 5Stir and Serve
   Stir the curry gently to combine the wilted spinach and creamy sauce. Serve over steamed basmati rice with warm garlic naan on the side. Scoop a generous portion of lamb and sauce onto each plate.
   Look for The curry is thick, creamy, and fragrant.
   Tip Use a large spoon to get both sauce and meat.

The curry is now a cohesive, creamy saag with tender lamb cubes throughout. Stirring gently reveals a silky emerald sauce with visible bits of garlic and cumin.

The aroma is intensely savory and buttery. When scooped over rice, the sauce clings to the grains, and the lamb is so tender it yields to the slightest pressure. The dish is ready to serve.

Common mistakes

The most common mistake is lifting the lid to check on the food, which lets out heat and extends cooking time. Resist the urge for at least 4 hours. Another is using lean lamb—without enough fat, the meat can dry out.

Stick with shoulder. Finally, don't skip the rest time after cooking; it helps the lamb stay moist. If the sauce seems too thin, leave the lid off for the last 30 minutes to thicken.

How to tell it’s done

The lamb is done when it's fork-tender and easily pulls apart. The sauce will be thick and creamy, with the spinach fully wilted into a deep green.

Use an instant-read thermometer to check that the thickest piece of lamb reads at least 145°F (63°C). After reaching temperature, let the meat rest for 3 minutes before serving to lock in the juices.
