Before you start
Before you begin, ensure your slow cooker is clean and placed on a stable, heat-resistant surface away from any splashes. Thaw the frozen wild mushrooms in the refrigerator if you prefer, though they can be added directly from frozen if you are in a rush.
Measure all your ingredients accurately to ensure the balance of the sauce is correct. Have your serving plates ready, preferably warmed, so the stew stays hot when it is served. Prepare your work area by clearing away any unnecessary items to keep the assembly process efficient and clean.

- 2 lb lamb shoulder, cut into 1-inch cubes
- 8 oz frozen wild mushrooms
- 2 tbsp veal stock powder
- 1/4 cup dry white wine
Instructions
Assembling the ingredients
- Assemble the stew basePlace the cubed lamb shoulder directly into the slow cooker basin. Add the frozen wild mushrooms on top of the lamb. Sprinkle the veal stock powder evenly over the meat and mushrooms, then pour the dry white wine over the entire mixture.Look for Ensure the stock powder is distributed across the surface to help create a consistent sauce base as the ingredients heat up.Tip Keep the slow cooker lid tightly sealed throughout the cooking process to trap moisture and ensure the lamb becomes fork-tender.
At this stage, all ingredients are layered in the slow cooker. The lamb is at the bottom, topped with mushrooms and the seasonings. Everything looks fresh and raw, with the wine and stock powder beginning to settle around the meat. Check that the slow cooker is plugged in and set to the correct low-heat setting before leaving it to cook. Ensure the lid is seated properly so that no steam escapes during the long cooking process.
Slow cooking the stew
- Slow cook until tenderCover the slow cooker and set to low heat for 6 hours. During the final hour, check the tenderness of the lamb. The meat should be completely soft and pull apart easily with a fork.Look for The stew should be bubbling gently and the aroma of the wine and mushrooms should permeate the kitchen.Tip Avoid opening the lid frequently, as each time the lid is lifted, the internal temperature drops and adds time to the cooking cycle.
The stew is now in the middle of the cooking process. You should notice a pleasant, savory aroma beginning to fill the kitchen. The liquid levels should be consistent, and the lamb should be submerged in the braising liquid. If you notice any excessive steam escaping from the edges, double-check that the lid is secure. The lamb is slowly becoming more tender as the collagen breaks down into the wine-based sauce, creating a rich base.
Serving the finished dish
- Final check and serveEnsure the lamb reaches an internal temperature of at least 145°F (63°C). Once cooked, let the stew rest for 5 minutes before serving on warm plates. Stir the sauce gently to incorporate the juices.Look for The sauce should be glossy and thickened, coating the back of a spoon, with the lamb tender and fully infused with the mushroom flavor.Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)Tip Serve with crusty bread or mashed potatoes to soak up the flavorful sauce developed during the long, slow cooking process.
The final stew should look dark, glossy, and incredibly inviting. The lamb is tender and easily pierced with a fork, and the mushrooms have softened into the sauce. The sauce should be well-incorporated and flavorful.
Before serving, give the stew a gentle stir to combine any concentrated flavors at the bottom of the pot. Ensure the lamb has reached the required temperature of 145°F (63°C) and that it has rested briefly to ensure optimal texture.
Common mistakes
A common mistake is overcrowding the slow cooker or using pieces of lamb that are too large, which prevents uniform cooking. Ensure the lamb is cut into consistent one-inch cubes.
Another error is checking the stew too often; every time you lift the lid, you lose significant heat and moisture, which extends the cooking time and can affect the final texture of the meat. Finally, do not skip the resting period, as this is crucial for the lamb to reach its peak tenderness and for the sauce to settle.
How to tell it’s done
The lamb is perfectly cooked when it is fork-tender, meaning it yields completely when pressed with a fork. The internal temperature must reach at least 145°F (63°C). The sauce should be glossy and have a rich, deep color.
If the meat still offers resistance, continue cooking for another 30 minutes. Always use a digital meat thermometer to verify the temperature in the thickest part of the lamb cubes. Let the dish rest for at least 3 minutes before serving to allow the juices to redistribute properly.
- Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
