Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 400°F (200°C). This ensures a beautifully browned top once your casserole is complete.

Step 2: Sauté the Meat and Vegetables

In a large skillet, brown the ground meat over medium heat. Add the diced onion and minced garlic, sautéing until translucent and fragrant, about 5-7 minutes.

Step 3: Combine the Filling

Stir in the frozen vegetables and cook for an additional 3-5 minutes. Then, mix in the tomato paste, beef broth, and thyme. Let this simmer for about 10 minutes, allowing the flavors to meld beautifully.

Step 4: Assemble the Casserole

In a greased 9×13 inch baking dish, spread the meat and vegetable mixture evenly. Top it generously with the mashed potatoes, creating a smooth, even layer over the filling.

Step 5: Bake to Perfection

Place in the preheated oven and bake for 25-30 minutes, until the top is golden brown. The aroma wafting through your kitchen will be irresistible!

Step 6: Serve and Enjoy!

Once out of the oven, let it sit for about 5 minutes before serving. This allows the layers to settle. Dig in and enjoy!
