How to Make Slow Cooked Vegetable and Lamb Casserole

1. Preheat your oven to 160 °C (or 140 °C if using a fan-forced oven). This creates the ideal environment for slow cooking the casserole, ensuring everything melds beautifully.

2. Coat the lamb pieces with flour using a plastic bag. Shake off any excess flour to ensure even browning and a lovely sauce texture later on.

3. Heat olive oil in a frying pan over medium heat. Brown the lamb in batches for about 5 minutes until golden brown, then transfer to a plate. This step maximizes flavor!

4. Sauté the onions and garlic in the same pan for about 3 minutes until aromatic and the onions are translucent, creating a wonderful base flavor for your casserole.

5. Combine the carrots, celery, Worcestershire sauce, thyme, chicken stock, canned tomatoes, and your browned lamb in the pan. Season with salt and pepper to taste, ensuring those savory flavors meld perfectly together.

6. Transfer the combined mixture to an ovenproof casserole dish. Cover tightly with foil and bake for 1 ¼ to 1 ½ hours or until everything is bubbling and tender, filling your kitchen with delicious aromas.

7. Remove the casserole from the oven. Layer the sliced potatoes on top of the lamb and sauce, then lightly spray them with oil. Bake uncovered for about 1 hour until the potatoes are tender.

8. Increase the oven temperature to 200 °C (or 180 °C fan-forced) and bake for an additional 10-15 minutes. This will create a beautifully golden and crisp potato topping that adds an irresistible crunch to your dish.

Optional: Serve with crusty bread for dipping in the luscious sauce.
