Description

Juicy beef simmers with garlic and herbs, then blends with zucchini slices beneath a blanket of bubbling cheddar, mozzarella, and Parmesan. Each bite offers a satisfying mix of savory meat, tender veggies, and gooey cheese.


Ingredients

  • 1 pound ground beef
  • 4 medium zucchini sliced
  • 1 medium onion diced
  • 2 cloves garlic minced
  • 14.5 ounce can diced tomatoes drained
  • 1 cup shredded cheddar cheese
  • 1 cup shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese
  • 1 teaspoon dried oregano
  • 1 teaspoon dried basil
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 2 tablespoons olive oil


Instructions

  1. Preheat the oven to 375°F and grease a 9×13-inch baking dish with a little olive oil.
  2. Heat the olive oil in a large skillet over medium heat and sauté the diced onion until translucent, about 4 minutes.
  3. Add the minced garlic to the skillet and cook for another minute until fragrant.
  4. Add the ground beef, breaking it apart with a spoon, and cook until browned and no longer pink, about 6–8 minutes.
  5. Stir in the drained diced tomatoes, dried oregano, dried basil, salt, and black pepper and simmer for 5 minutes.
  6. Spread half of the beef mixture evenly in the bottom of the prepared baking dish.
  7. Arrange half of the zucchini slices over the beef layer, then sprinkle half of each cheese (cheddar, mozzarella, Parmesan) over the zucchini.
  8. Repeat with the remaining beef mixture, zucchini slices, and cheeses to create a second layer.
  9. Cover the dish with foil and bake for 20 minutes, then remove the foil and bake for an additional 10–15 minutes until the cheese is bubbly and golden.
  10. Let the casserole rest for 5 minutes before slicing and serving.

Notes

  • You can substitute ground turkey or chicken for a lighter version.
  • For extra flavor, add 1/2 cup chopped mushrooms or red bell pepper.
  • Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
  • Feel free to swap in pepper jack cheese for a mild spicy twist.
