- 1 medium onion, finely chopped
- 2 cloves garlic, minced
- 1 cup crushed tomatoes (or tomato sauce)
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- ½ teaspoon paprika
- ½ teaspoon salt (adjust to taste)
- ¼ teaspoon black pepper
- 1 cup shredded cheddar cheese
- ½ cup shredded mozzarella cheese
- 2 tablespoons olive oil
- ½ cup sour cream (optional, for added creaminess)
- 2 tablespoons fresh parsley, chopped (for garnish)
Step-by-Step Instructions
Step 1: Prepare the base
Heat olive oil in a skillet over medium heat. Add the onions and garlic, sautéing until fragrant and translucent.
Step 2: Cook the beef
Add the ground beef to the skillet. Break it apart with a spatula and cook until browned, then season with salt, pepper, paprika, oregano, and basil. Stir in the crushed tomatoes and let simmer for 8–10 minutes.
Step 3: Prepare the zucchini
While the beef simmers, slice the zucchinis into thin, even rounds. Pat them dry with a paper towel to avoid excess moisture in the casserole.
Step 4: Assemble the casserole
In a greased baking dish, layer half of the zucchini slices. Spread half of the beef mixture over them. Add a few spoonfuls of sour cream if using. Repeat the layers with remaining zucchini and beef.
Step 5: Add the cheesy topping
Sprinkle cheddar and mozzarella evenly over the top, ensuring full coverage for a golden crust.
Step 6: Bake to perfection
Bake in a preheated oven at 375°F (190°C) for 25–30 minutes, or until the cheese is bubbling and lightly browned.
Step 7: Rest and serve
Let the casserole rest for 5–7 minutes before serving to allow flavors to meld together. Garnish with fresh parsley.
