Begin by preheating your oven to 400°F (200°C) to ensure it’s hot and ready for baking.
In a large skillet set over medium heat, add the ground lamb or beef. Cook for approximately 5-7 minutes, breaking the meat apart with a spatula as it browns. Once browned, drain any excess fat from the skillet.
Introduce the diced onion and minced garlic into the skillet. Sauté them together for about 3 minutes, or until the onion looks soft and translucent.
Add the mixed vegetables to the skillet, allowing them to cook for another 3-4 minutes until they become slightly tender and vibrant in color.
Stir in the tomato paste, broth, Worcestershire sauce, dried thyme, and season with salt and black pepper. Bring the mixture to a gentle simmer and let it cook for 5 minutes, allowing the flavors to blend beautifully.
Carefully transfer the hearty meat and vegetable mixture to a baking dish, spreading it out evenly across the bottom.
With a spatula, spoon and spread the mashed potatoes over the meat mixture, ensuring full coverage. For a decorative touch, create peaks or swirls with the spatula on top of the potatoes.
If you are using cheese, sprinkle it generously over the mashed potatoes for an enticingly gooey topping.
Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and bubbling with deliciousness.
Once baked, remove the dish from the oven and allow it to cool for a few minutes. If desired, garnish with fresh parsley before serving for a pop of color and freshness.
Notes
Serve in individual bowls for a cozy dining experience. Garnish with extra parsley for added freshness.
