Directions:
Preheat oven to 375°F (190°C).
In a large skillet, cook ground beef over medium heat until brown. Suction any excess fat.
Add chopped onion and minced garlic to the skillet with the minced meat. Fry the onion until it becomes transparent and fragrant.
Add the diced tomatoes, tomato sauce, dried oregano, dried basil, and salt and pepper. Bring to a boil and cook for about 10 minutes, allowing the flavors to meld.
Meanwhile, prepare the mashed potatoes using your preferred method. You can boil potatoes until tender, then mash them with butter, milk, salt, and pepper until smooth and creamy.
Transfer the ground beef mixture to a greased 9″ x 13″ baking dish, spreading it evenly.
Spoon mashed potatoes over beef mixture, spreading to coat entire surface.
Sprinkle the grated cheddar cheese evenly over the mashed potatoes.
Place the skillet in the preheated oven and bake for 25 to 30 minutes, or until the cheese is melted, bubbling, and the skillet is heated through.
Once cooked, remove the casserole from the oven and let it cool for a few minutes before serving.
Enjoy !
