Ingredients

For the Casserole

1 pound ground beef
2 medium zucchinis, sliced
1 cup marinara sauce
1 1/2 cups shredded mozzarella cheese
1/2 cup grated Parmesan cheese
1 teaspoon Italian seasoning
Salt and black pepper, to taste

Optional Additions

1 small onion, finely chopped
2 cloves garlic, minced
1/2 teaspoon paprika
1/4 teaspoon red pepper flakes, for a little heat
1 tablespoon olive oil
Fresh parsley or basil, for garnish

Instructions

1. Prepare the Oven

Preheat the oven to 375°F, or 190°C. Lightly grease a medium baking dish with olive oil or non-stick cooking spray.

A deep casserole dish works best because it helps hold the layers of beef, zucchini, sauce, and cheese.

2. Prepare the Zucchini

Wash the zucchinis and slice them into thin rounds. Try to keep the slices similar in thickness so they cook evenly.

Place the zucchini slices on a clean towel or paper towels. Sprinkle lightly with salt and let them sit for about 10 minutes. This helps remove extra moisture and prevents the casserole from becoming watery.

After 10 minutes, gently pat the zucchini dry.

3. Cook the Ground Beef

Heat a large skillet over medium heat. Add the ground beef and cook until browned, breaking it apart with a spoon as it cooks.

If using onion and garlic, add the chopped onion first and cook until softened, then add the garlic and cook for about 30 seconds before adding the beef.

Drain any extra grease from the pan if needed.

4. Season the Beef

Add the Italian seasoning, salt, black pepper, paprika, and red pepper flakes if using. Stir well so the beef is evenly seasoned.

Pour in the marinara sauce and mix until the beef is coated in the sauce. Let it simmer for 3 to 5 minutes so the flavors come together.

5. Start Layering the Bake

Spread a small amount of the beef and marinara mixture on the bottom of the prepared baking dish.

Add a layer of zucchini slices over the beef. Slightly overlap the slices so they cover the surface.

6. Add Cheese

Sprinkle part of the shredded mozzarella and grated Parmesan over the zucchini layer.

The cheese helps bind the casserole together and gives it a rich, golden topping.

7. Repeat the Layers

Add another layer of the beef mixture, then another layer of zucchini slices, followed by more mozzarella and Parmesan.

Continue layering until all the ingredients are used, finishing with a generous layer of cheese on top.

8. Bake the Casserole

Place the baking dish in the preheated oven. Bake uncovered for 25 to 30 minutes, or until the zucchini is tender and the cheese is melted, bubbly, and golden brown on top.

If you want a darker, crispier cheese topping, broil the casserole for 2 to 3 minutes at the end. Watch carefully so it does not burn.

9. Let It Rest

Remove the casserole from the oven and let it rest for 8 to 10 minutes before serving.

This resting time helps the layers set and makes it easier to slice and serve.

10. Garnish and Serve

Sprinkle fresh parsley or basil over the top before serving. Serve warm and enjoy.

Serving Suggestions

Ground Beef Zucchini Bake is delicious served on its own as a low-carb meal. You can also pair it with a fresh green salad, roasted vegetables, cauliflower rice, or garlic butter green beans.

For a heartier meal, serve it with crusty bread, rice, or pasta if you are not keeping it low carb.

Tips for Best Results

Pat the zucchini dry before baking to avoid extra liquid in the casserole.

Use a thick marinara sauce so the bake stays rich and not watery.

Let the casserole rest before slicing so the layers hold together better.

Use freshly shredded mozzarella for the best melting texture.

Add extra Parmesan on top for a stronger cheesy flavor.

Storage

Store leftovers in an airtight container in the refrigerator for up to 4 days.

To reheat, warm individual portions in the microwave or reheat the casserole in the oven at 350°F, or 175°C, until hot.

This dish can also be frozen for up to 2 months. For best results, thaw overnight in the refrigerator before reheating.
