Cheesy Beef and Mashed Potato Casserole

For the beef layer

450g (1 lb) ground beef

1 medium onion, finely chopped

2 cloves garlic, minced

1 cup marinara or tomato sauce

1 tablespoon tomato paste

1 tablespoon Worcestershire sauce

1 teaspoon paprika

Salt and pepper to taste

1 tablespoon olive oil

For the mashed potatoes

4 large potatoes, peeled and cubed

1/4 cup butter

1/2 cup milk or cream

Salt and pepper to taste

For the cheese layer

2 cups shredded cheddar or mozzarella cheese

1/4 cup grated Parmesan cheese (optional)

Instructions

Preheat your oven to 180°C (350°F).

Boil the peeled and cubed potatoes in salted water until fork-tender, about 15–20 minutes.

Drain the potatoes and mash them with butter, milk, salt, and pepper until smooth and creamy. Set aside.

In a large skillet, heat olive oil over medium heat and sauté the chopped onion until soft.

Add minced garlic and cook for another minute.

Add the ground beef and cook until browned, breaking it apart as it cooks.

Stir in tomato sauce, tomato paste, Worcestershire sauce, paprika, salt, and pepper. Let it simmer for 5–7 minutes.

In a baking dish, spread a layer of mashed potatoes, then add the beef mixture evenly on top.

Cover with the remaining mashed potatoes and smooth the surface.

Sprinkle shredded cheese and Parmesan evenly over the top.

Bake for 20–25 minutes until the cheese is melted, bubbly, and golden.

How to Make

Start by preparing all ingredients in advance to streamline the cooking process.

Focus on achieving a creamy texture for the mashed potatoes, as this is key to a soft and rich casserole.

Cook the beef mixture thoroughly and allow the sauce to thicken slightly for deeper flavor.

Layer carefully to ensure even distribution of meat and potatoes in every bite.

Bake until the cheese forms a golden crust, which adds both texture and visual appeal.

Variations

Swap ground beef with ground chicken or turkey for a lighter version.

Add vegetables like carrots, peas, or corn to boost nutrition and flavor.

Use sweet potatoes instead of regular potatoes for a healthier twist.

Try different cheeses such as gouda, mozzarella, or a cheese blend for variety.

Add chili flakes or hot sauce for a spicy casserole variation.

Tips

Use starchy potatoes like Russet for the creamiest mashed texture.

Do not overmix mashed potatoes to avoid a gluey consistency.

Let the casserole rest for 5 minutes before serving to help it set.

For extra flavor, add herbs like thyme or parsley to the beef mixture.

Grate cheese fresh for better melting and taste.
