Prepare the ingredients. Cut the lamb into small cubes, chop the onion and carrots, and mince the garlic. Keep everything close it makes cooking smoother.
Warm the olive oil. Set a large skillet over medium heat. When the oil starts to shimmer, add the lamb and brown it on all sides. This builds flavor that carries through the whole stew.
Layer the crockpot. Add the carrots and other root vegetables first, then the onions and garlic. Place the browned lamb on top. Sprinkle in the herbs, salt, and pepper.
Add tomatoes and broth. Spoon in the tomato paste, pour in the chopped tomatoes, and finish with the broth until the ingredients are almost covered.
Let it cook slow. Cover the crockpot and cook on low for about 6 to 8 hours, or on high for 4 to 5 hours. You will know it’s done when the lamb falls apart easily.
Finish with lemon and parsley. Stir in lemon juice once cooking is done. Taste and adjust seasoning if needed. Sprinkle fresh parsley before serving.
Serve and enjoy. Let it rest for 10 minutes before serving. The stew thickens slightly and the flavors come together beautifully.
