Ingredients
- 1 lb ground beef
- 2 medium zucchinis, sliced
- 1 medium onion, chopped
- 2 cloves garlic, minced
- 1 cup crushed tomatoes (canned or fresh)
- 1 tsp Italian seasoning
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1 cup shredded cheddar cheese
- 1 cup breadcrumbs (optional for topping)
- 2 tbsp olive oil
- Fresh parsley, chopped (for garnish)
Directions
- Preheat Oven: Begin by preheating your oven to 350°F (175°C). This ensures that your casserole cooks evenly.
- Brown the Beef: In a large skillet, heat the olive oil over medium heat. Add the ground beef, breaking it apart with a spatula. Cook until browned, about 5-7 minutes. Drain excess grease if necessary.
- Sauté the Vegetables: To the skillet with the ground beef, add the chopped onion and minced garlic. Sauté for about 3-4 minutes until the onion becomes translucent.
- Add Zucchini and Tomatoes: Stir in the sliced zucchini and crushed tomatoes. Season with Italian seasoning, salt, and black pepper. Allow the mixture to simmer for about 5 minutes, letting the flavors meld together.
- Combine Ingredients: Remove the skillet from heat. If using breadcrumbs, mix them with the beef and vegetable mixture for added texture.
- Layer the Casserole: In a greased 9×13 inch baking dish, spread the beef and vegetable mixture evenly.
- Add Cheese: Sprinkle the shredded cheddar cheese evenly over the top. This will give a deliciously gooey finish once baked.
- Cover and Bake: Cover the baking dish with aluminum foil and bake in the preheated oven for 20 minutes. Remove the foil and bake for an additional 10-15 minutes, until the cheese is bubbly and golden.
- Garnish and Serve: Once cooked, take the casserole out of the oven. Sprinkle freshly chopped parsley on top before serving.

Serving Suggestions

Variations
Feel free to personalize this casserole according to your taste. Here are a few ideas:
- Add More Veggies: Incorporate mushrooms, bell peppers, or spinach for extra nutrition. Just sauté them along with the onions and garlic.
- Change the Cheese: While cheddar is a favorite, feel free to experiment with mozzarella, Monterey Jack, or even a mix of cheeses for a different flavor profile.

Nutritional Benefits
Zucchini casserole offers numerous health benefits. Zucchini is low in calories and high in fiber, aiding digestion and promoting a feeling of fullness. Ground beef provides essential protein and iron, making it a great choice for muscle repair and energy. Combining these ingredients not only results in a savory dish but also a nutritious one, making it easier to maintain a balanced diet.
Tips for Success
- Select the Right Zucchini: Choose firm, unblemished zucchinis for the best texture and flavor.
- Avoid Overcooking: Keep an eye on the zucchini while cooking to prevent it from becoming mushy. You want it to retain some crunch.
- Make Ahead: You can prepare the casserole a day in advance. Just cover it and leave it in the fridge. When ready to cook, simply pop it in the oven, adjusting the bake time as necessary.
Storing and Freezing
If you have leftovers, allow the casserole to cool completely before transferring it to an airtight container. It can be stored in the refrigerator for up to three days. Alternatively, you can freeze it for longer storage; it should last up to three months in the freezer. To reheat, simply thaw overnight in the fridge, then bake it in a 350°F (175°C) oven until heated through.
