Ingredients
- 1 pound ground beef
- 2 medium zucchini (sliced)
- 1 small onion (diced)
- 2 cloves garlic (minced)
- 1 cup tomato sauce
- 2 cups shredded cheddar cheese
- 1 cup shredded mozzarella cheese
- 1 teaspoon Italian seasoning
- Salt and black pepper to taste
- 1 tablespoon olive oil
- 2 tablespoons grated Parmesan cheese
- Chopped parsley for garnish (optional)
Instructions
- Step 1: Preheat your oven to 375°F (190°C).
- Step 2: Heat the olive oil in a large skillet over medium heat. Cook the diced onion until softened, about 3-4 minutes, then add the minced garlic and cook for another 30 seconds.
- Step 3: Add the ground beef to the skillet and cook until browned, breaking it apart with a spoon. Drain any excess grease.
- Step 4: Stir in the tomato sauce, Italian seasoning, salt, and black pepper. Let the mixture simmer for 5 minutes to combine the flavors.
- Step 5: Arrange half of the zucchini slices evenly in a greased baking dish.
- Step 6: Spoon half of the beef mixture over the zucchini, then sprinkle half of the shredded cheddar and mozzarella cheeses on top.
- Step 7: Repeat the layering with the remaining zucchini, beef mixture, and cheeses. Finish by sprinkling the grated Parmesan cheese over the top.
- Step 8: Bake uncovered for 30-35 minutes, or until the cheese is golden and bubbling.
- Step 9: Remove from the oven and let the casserole rest for 10 minutes before serving. Garnish with chopped parsley if desired.
Tips & Variations
- For extra flavor, sauté the zucchini slices briefly before layering to reduce their moisture.
- Try using ground turkey or chicken as a leaner alternative to ground beef.
- Add a pinch of red pepper flakes to the beef mixture for a spicy kick.
- Swap out the cheddar for pepper jack or gouda for a different cheese profile.
Storage
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat portions in the microwave until warmed through, or in the oven at 350°F (175°C) for 15-20 minutes to preserve the cheese’s texture.

Ingredients
Main Ingredients
- 1 pound ground beef
- 2 medium zucchini (sliced)
- 1 small onion (diced)
- 2 cloves garlic (minced)
- 1 cup tomato sauce
- 2 cups shredded cheddar cheese
- 1 cup shredded mozzarella cheese
- 1 teaspoon Italian seasoning
- Salt and black pepper to taste
- 1 tablespoon olive oil
- 2 tablespoons grated Parmesan cheese
- Chopped parsley for garnish (optional)
Instructions
- Preheat the Oven: Preheat your oven to 375°F (190°C) to prepare for baking the casserole.
- Sauté Onions and Garlic: Heat olive oil in a large skillet over medium heat. Cook the diced onion until softened, about 3-5 minutes, then add the minced garlic and cook for an additional 30 seconds to release its aroma.
- Brown the Ground Beef: Add the ground beef to the skillet and cook until browned throughout, breaking it up with a spatula. Drain any excess grease to keep the dish from becoming too oily.
- Simmer with Tomato Sauce and Seasonings: Stir in the tomato sauce, Italian seasoning, salt, and black pepper. Allow the mixture to simmer for about 5 minutes to blend the flavors and thicken the sauce slightly.
- Layer Ingredients in Baking Dish: Grease a baking dish and arrange half of the zucchini slices on the bottom. Spoon half of the beef mixture evenly over the zucchini, then sprinkle with half of the shredded cheddar and mozzarella cheeses.
- Repeat Layers: Repeat the layering process with the remaining zucchini slices, beef mixture, and cheeses. Finally, sprinkle the grated Parmesan cheese evenly over the top layer to add a savory, crispy crust once baked.
- Bake the Casserole: Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the cheese is melted, golden, and bubbling.
- Rest Before Serving: Remove the casserole from the oven and let it rest for 10 minutes to set. Garnish with chopped parsley if desired before serving.
