  • 3 cloves garlic, minced
  • 1 teaspoon salt
  • 1 teaspoon black pepper
  • 1 teaspoon paprika
  • 1 teaspoon Italian seasoning
  • 1 tablespoon Worcestershire sauce
  • 2 cups diced tomatoes (fresh or canned, drained)
  • 1 cup sweet corn kernels

For the Potato Layer

  • Salt and pepper to taste

For the Cheese Topping

  • 2 cups shredded mozzarella cheese
  • 1 cup shredded cheddar cheese
  • ¼ cup grated Parmesan cheese
  • 2 tablespoons chopped fresh parsley

Instructions

Step 1: Prepare the Potatoes

Boil the potatoes in salted water for about 15–20 minutes until fork tender. Drain well, then mash with butter, milk, sour cream, salt, and pepper until smooth and creamy.

Step 2: Cook the Beef

Heat a large skillet over medium-high heat. Cook the ground beef until browned. Add chopped onion and garlic, cooking until softened. Stir in Worcestershire sauce, paprika, Italian seasoning, salt, and pepper. Mix in the tomatoes and corn, then simmer for 5 minutes.

Step 3: Assemble the Casserole

Preheat the oven to 375°F (190°C).

Grease a 9×13-inch baking dish.

Spread the beef mixture evenly across the bottom.

Carefully spread the mashed potatoes over the beef.

Top generously with mozzarella, cheddar, and Parmesan cheeses.

Step 4: Bake

Bake for 25–30 minutes until the cheese is melted, bubbly, and lightly golden.

Step 5: Garnish

Sprinkle with freshly chopped parsley before serving.

Cooking Methods

  • Traditional Oven: Bake until bubbly and golden.
  • Make-Ahead: Assemble the casserole a day ahead and refrigerate until ready to bake.
  • Freezer Friendly: Freeze before baking for up to 3 months. Thaw overnight before baking.
  • Slow Cooker: Cook the beef first, then layer everything in a slow cooker and heat on low for 3–4 hours.
