Before you start
Before starting, ensure your lamb is cut into uniform, bite-sized chunks to promote even cooking. Peel the potatoes and cut them into chunks similar in size to the lamb. Have your chicken broth measured and ready, and clear a clean, stable space for your slow cooker.
Ensure the cord is easily accessible and the slow cooker is placed away from any flammable materials. Having all ingredients prepared on a tray before you begin makes the assembly process smooth and efficient.

- 2 lb lamb shoulder, cut into 1-inch chunks
- 1 lb russet potatoes, peeled and cut into chunks
- 2 tbsp colombo powder
- 2 cups chicken broth
Instructions
Layering the ingredients
- Assemble the ingredientsPlace the lamb chunks at the bottom of your slow cooker. Add the potato chunks on top of the lamb. Sprinkle the colombo powder evenly over the potatoes and lamb, ensuring the spices are well distributed.Look for Ingredients should be layered neatly in the slow cooker bowl.Tip Ensure the lamb is at the bottom so it remains submerged in the liquid for even cooking.
The lamb and potatoes are arranged in the slow cooker with the spice powder evenly distributed. The initial setup should look organized, with the lamb at the bottom to ensure it stays in the hottest part of the cooker. Check that the spices are not clumped in one spot, but rather spread across the surface of the ingredients so that the flavor permeates the entire pot as the broth is added.
Slow cooking the stew
- Add liquid and cookPour the chicken broth over the ingredients in the slow cooker. Cover the slow cooker with its lid. Set the slow cooker to the low setting and cook for 6 hours until the lamb is tender.Look for The broth should just cover the meat and potatoes.Tip Avoid lifting the lid during the cooking process to maintain a consistent temperature.
The broth has been added and the lid is secured. During this phase, the slow cooker will begin to emit a rich, aromatic scent. The liquid should be bubbling gently. You should check that the seal on the lid is tight to prevent moisture loss. The meat and potatoes are currently softening and absorbing the colombo spices, creating a deep, complex base that will define the final flavor of the dish.
Final resting and serving
- Finish and serveOnce the cooking time is complete, verify the lamb has reached an internal temperature of 145°F (63°C). Turn off the slow cooker and let the dish rest for at least 3 minutes before serving to allow the flavors to settle.Look for The lamb should pull apart easily with a fork and the potatoes should be soft.Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)Tip Check the consistency of the sauce; if it is too thin, you can simmer it on high for a few minutes with the lid off.
The lamb is tender and the potatoes are perfectly cooked through. The dish should look like a rich, golden-hued stew with a fragrant, thick sauce. Before serving, let the dish rest for at least five minutes.
This resting period is essential as it allows the sauce to thicken slightly and the flavors to meld together perfectly, ensuring every serving is hot, flavorful, and ready to be enjoyed immediately.
Common mistakes
A common mistake is overcrowding the slow cooker, which can prevent the ingredients from cooking evenly and potentially cause the dish to overflow. Another error is using a cut of meat that is too lean, which will result in dry and tough lamb after hours of cooking.
Avoid using high heat settings for the entire duration, as this can cause the sauce to boil too rapidly and may lead to uneven cooking of the potatoes. Always ensure the lid is properly seated.
How to tell it’s done
The dish is done when the lamb is fork-tender and pulls apart with very little pressure. The potatoes should be soft throughout but still hold their shape. Use a digital meat thermometer to ensure the lamb has reached an internal temperature of 145°F (63°C).
The sauce should be thickened and fragrant. If the meat offers resistance, continue cooking for another thirty minutes before checking again, as cooking times can vary based on the specific slow cooker's heat intensity.
- Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
