A hearty and flavorful casserole combining seasoned beef and creamy garlic mashed potatoes, perfect for a comforting meal.
Preheat your oven to 400°F (200°C).
Preheating ensures even cooking and the right texture for the casserole.
In a skillet over medium heat, cook the ground beef until browned, breaking it into small pieces as it cooks.
Stir frequently to prevent sticking and ensure even browning.
Add the chopped onion and diced carrot to the skillet and cook until softened.
Cooking the vegetables with the beef enhances their flavor.
Stir in the Worcestershire sauce and frozen peas, mixing well.
Ensure the peas are evenly distributed for consistent flavor.
Transfer the beef mixture to a baking dish, spreading it evenly.
Press the mixture down gently to create an even layer.
Spread the garlic-flavored mashed potatoes over the beef mixture, smoothing the top.
Use a spatula for a smooth and even layer.
Bake in the preheated oven for 20 minutes or until the top is golden and the casserole is heated through.
Check halfway through to ensure even cooking.
Serve the casserole hot, garnished with fresh parsley if desired.
Let the casserole rest for a few minutes before serving to set the layers.
