Recipe Information
Ingredients
- 4 medium zucchini
- 1 pound ground beef
- 1 medium yellow onion
- 2 large garlic cloves
- 2 tablespoons olive oil
- 14 ounces diced tomatoes
- 2 tablespoons tomato paste
- 1 teaspoon Italian seasoning
- 1 teaspoon salt
- 0.5 teaspoon black pepper
- 0.25 teaspoon red pepper flakes
- 1.5 cups shredded mozzarella cheese
- 0.5 cups grated Parmesan cheese
- 2 tablespoons fresh parsley (optional, for garnish)
Instructions
Preheat your oven to 375°F (190°C).
Wash the zucchini thoroughly and slice them into thin rounds, about 1/4 inch thick. Set aside.
Chop the onion into small pieces and mince the garlic cloves.
Heat olive oil in a large skillet over medium heat. Add the ground beef and cook until browned, breaking it up with a spoon. Drain any excess fat if necessary.
Add the chopped onion and garlic to the skillet with the ground beef. Cook for 3-4 minutes, or until the onion is translucent.
Stir in the diced tomatoes (with their juices) and tomato paste. Mix well to combine.
Add the Italian seasoning, salt, black pepper, and red pepper flakes. Let the mixture simmer for 5-7 minutes to develop the flavors.
In a greased 9x13-inch baking dish, layer half of the sliced zucchini on the bottom.
Spread half of the beef and tomato mixture over the zucchini slices.
Sprinkle 1/2 cup of shredded mozzarella cheese over the beef layer.
Repeat the layers: add the remaining zucchini slices, the rest of the beef mixture, and then top with the remaining shredded mozzarella and grated Parmesan cheese.
Cover the dish with aluminum foil and bake in the preheated oven for 25 minutes.
Remove the foil and bake for an additional 10 minutes, or until the cheese is melted and bubbly, and the zucchini is tender.
Let the casserole rest for 5-10 minutes before serving. Garnish with fresh parsley if desired.
Serve warm and enjoy!
