Ingredients

For the Beef Filling

  • 2 lbs (900g) lean ground beef
  • 1 tbsp olive oil
  • 1 medium onion, finely diced
  • 4 cloves garlic, minced
  • 10 oz (300g) mushrooms, sliced
  • 2 tbsp tomato paste
  • 1 can (14 oz / 400g) crushed tomatoes
  • 1 tsp Worcestershire sauce
  • 1 tsp Italian seasoning
  • 1 tsp paprika
  • ½ tsp dried oregano
  • ½ tsp black pepper
  • 1 tsp salt (or to taste)
  • ½ tsp red pepper flakes (optional)

For the Cheese Layer

  • 2 cups shredded mozzarella cheese
  • 1 cup shredded sharp cheddar cheese
  • ¼ cup grated Parmesan cheese

For Garnish

  • Fresh chopped parsley
  • Extra cracked black pepper

Instructions

Step 1: Prepare the Filling

Heat olive oil in a large skillet over medium-high heat. Add the diced onion and cook for about 3–4 minutes until softened. Stir in the minced garlic and cook for another 30 seconds until fragrant.

Step 2: Brown the Beef

Add the ground beef and cook until browned, breaking it apart with a spoon as it cooks. Drain excess grease if necessary.

Step 3: Cook the Mushrooms

Add the sliced mushrooms to the skillet and cook for about 5–6 minutes until they release their moisture and become lightly browned.

Step 4: Make the Sauce

Stir in the tomato paste and cook for 1 minute. Add the crushed tomatoes, Worcestershire sauce, Italian seasoning, paprika, oregano, salt, pepper, and optional red pepper flakes. Simmer for 10–12 minutes until the sauce thickens.

Step 5: Assemble the Bake

Preheat your oven to 375°F (190°C).

Transfer the beef mixture into a lightly greased 9×13-inch baking dish and spread evenly.

Sprinkle mozzarella over the top, followed by cheddar and Parmesan for an extra cheesy finish.

Step 6: Bake

Bake uncovered for 20–25 minutes, or until the cheese is fully melted, bubbling, and lightly golden brown.

For an extra crispy top, broil for the final 2–3 minutes while watching carefully.

Step 7: Rest & Serve

Allow the casserole to rest for about 5 minutes before serving. Garnish with freshly chopped parsley and cracked black pepper.

Serve hot with garlic bread, roasted vegetables, mashed potatoes, buttered noodles, or a fresh salad.

Tips & Notes

  • Use freshly shredded cheese for the smoothest melt and best texture.
  • Cremini or baby bella mushrooms provide a deeper, richer flavor than white mushrooms.
  • Add spinach, zucchini, or bell peppers for extra vegetables.
  • Mix in cooked pasta or rice to turn it into a complete one-dish meal.
  • For a richer casserole, stir in ½ cup heavy cream or softened cream cheese before baking.
  • You can substitute ground turkey or chicken for a lighter version.
  • Leftovers taste even better the next day as the flavors continue to develop.

Storage

  • Refrigerator: Store in an airtight container for up to 4 days.
  • Freezer: Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
  • Reheating: Warm in a 350°F (175°C) oven for 15–20 minutes or microwave individual portions until heated through.
