This comforting casserole layers seasoned ground beef, creamy mashed potatoes, and melted cheese for a delicious, easy dinner.

Ingredients

For the Beef Layer:

  • 450g (1 pound) 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

  • ¼ cup butter

  • ½ cup milk or cream

  • Salt and pepper, to taste

For the Cheese Layer:

  • 2 cups shredded cheddar or mozzarella cheese

  • ¼ cup grated Parmesan cheese (optional)

Instructions

Step 1: Make the Mashed Potatoes
Peel and cube the potatoes. Place them in a large pot of salted water and bring to a boil. Cook for 15 to 20 minutes, until tender. Drain well. Add the butter, milk, salt, and pepper. Mash until smooth and creamy. Set aside.

Step 2: Cook the Beef
While the potatoes are cooking, heat the olive oil in a large skillet over medium-high heat. Add the ground beef and cook until browned, breaking it into crumbles with a spoon, about 6 to 8 minutes. Add the chopped onion and cook for 3 to 4 minutes until softened. Stir in the garlic and cook for 1 minute more.

Step 3: Add the Sauce
Stir in the marinara sauce, tomato paste, Worcestershire sauce, paprika, salt, and pepper. Simmer for 5 minutes, until the sauce thickens slightly.

Step 4: Assemble the Casserole
Preheat your oven to 350°F (175°C). Lightly grease a baking dish. Spread half of the mashed potatoes evenly over the bottom of the dish. Top with the beef mixture. Spread the remaining mashed potatoes over the beef. Sprinkle with the shredded cheddar and Parmesan cheese.

Step 5: Bake
Bake for 20 to 25 minutes, or until the cheese is melted, bubbly, and lightly golden. Let rest for 5 minutes before serving.


Tips for the Perfect Casserole

  • Use Starchy Potatoes: Russet or Yukon Gold potatoes make the creamiest mashed potatoes.

  • Do Not Overcook the Beef: Brown the beef until just cooked through to keep it tender.

  • Let the Casserole Rest: Allowing the casserole to rest for 5 minutes after baking helps the layers set and makes serving easier.

  • Add Vegetables: Stir in mushrooms, bell peppers, or peas to the beef mixture for extra nutrition.

  • Make Ahead: Assemble the casserole up to a day in advance and refrigerate. Add 10 minutes to the baking time.


Variations and Substitutions

  • Ground Turkey: Substitute ground turkey for a lighter version.

  • Add Bacon: Crumble cooked bacon over the cheese layer before baking.

  • Spicy Version: Add red pepper flakes or use spicy marinara sauce.

  • Herb Addition: Add 1 teaspoon of dried oregano or basil to the beef mixture.

  • Sour Cream Topping: Dollop sour cream over the finished casserole.

  • Gluten-Free: Use gluten-free Worcestershire sauce and ensure the marinara is gluten-free.


What to Serve with This Casserole

This hearty casserole is a complete meal on its own, but it pairs beautifully with:

  • Simple Salad: A crisp green salad with a tangy vinaigrette balances the richness.

  • Roasted Vegetables: Serve alongside green beans, broccoli, or roasted carrots.

  • Crusty Bread: Perfect for soaking up any extra sauce.

  • Cornbread: A classic comfort food pairing.


Storage and Reheating

  • Refrigerator: Store leftovers in an airtight container for up to 4 days.

  • Reheating: Reheat in a 350°F oven covered with foil for 15 to 20 minutes, or in the microwave for individual portions.

  • Freezer: This casserole can be frozen for up to 2 months. Thaw overnight in the refrigerator before reheating.
