Ingredients
Serves 6
- 2 lbs (900g) lamb shoulder, cut into 2-inch chunks
- 3 medium carrots, sliced
- 3 medium potatoes, cut into chunks
- 1 large onion, diced
- 4 garlic cloves, minced
- 2 celery stalks, chopped
- 1 cup frozen peas (added at the end)
- 2 cups beef or lamb broth
- 1 can (14 oz) diced tomatoes
- 2 tbsp tomato paste
- 2 tbsp olive oil
- 1 tsp fresh rosemary, chopped (or ½ tsp dried)
- 1 tsp fresh thyme leaves
- 1 tsp smoked paprika
- Salt and black pepper to taste
- 2 tbsp cornstarch + 2 tbsp cold water (optional, for thickening)
Instructions

- Season the lamb. Pat your lamb chunks dry with paper towels and season generously with salt, pepper, and smoked paprika.
- Sear the meat. Heat olive oil in a skillet over medium-high heat. Brown the lamb in batches for 2–3 minutes per side. This step builds serious depth of flavor — don’t skip it!
- Build your base. Add the seared lamb to the slow cooker. Toss in the onion, garlic, carrots, celery, and potatoes.
- Add liquids and seasonings. Pour in the broth, diced tomatoes, and tomato paste. Stir in rosemary and thyme.
- Slow cook. Cover and cook on LOW for 8 hours or HIGH for 4–5 hours, until the lamb is tender and falling apart.
- Thicken the stew (optional). About 30 minutes before serving, mix cornstarch with cold water and stir it into the stew. Leave the lid slightly ajar so it can thicken.
- Add the peas. Stir in frozen peas in the last 10–15 minutes of cooking.
- Taste and adjust. Give it a good stir, check the seasoning, and serve hot.
Tips for the Best Slow Cooker Lamb Stew
Getting a tender, flavorful slow cooker lamb stew every single time really comes down to a few simple tricks. First, always sear your meat before it hits the slow cooker — those caramelized bits on the outside add a whole new dimension to the broth. Second, resist the temptation to lift that lid while it’s cooking. Every time you open it, you lose precious heat and steam, which adds cooking time.
Also, lamb shoulder will always outperform lamb leg in this recipe. It has more fat and connective tissue, which breaks down beautifully during long, slow cooking. And if you have the time, make this stew a day ahead — the flavors intensify overnight and the next-day version is truly something special.
