How to Make Ground Beef Zucchini Casserole
Making the Ground Beef Zucchini Casserole is a breeze, and the end result is a delicious and satisfying meal that’s sure to impress.
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish to prevent the casserole from sticking.
Step 2: Cook the Ground Beef
Heat the olive oil in a skillet over medium heat. Add the chopped onion and minced garlic, and sauté until fragrant. Then, add the ground beef and season with salt, pepper, and Italian seasoning. Cook the beef until it’s browned and crumbled.
Step 3: Layer the Casserole
Start by placing a layer of zucchini slices in the bottom of the prepared baking dish. Spread some of the cooked ground beef mixture over the zucchini, and then add small dollops of ricotta cheese (if using). Repeat these layers until all the ingredients are used up, finishing with a layer of mozzarella and Parmesan cheese on top.
Step 4: Bake the Casserole
Cover the casserole with foil and bake for 20 minutes. Then, remove the foil and continue baking for another 10-15 minutes, or until the cheese is melted, bubbly, and golden brown.
Step 5: Serve and Enjoy
Once the Ground Beef Zucchini Casserole is out of the oven, let it cool for a few minutes. Then, garnish it with fresh basil leaves and a sprinkle of red pepper flakes, if desired. Serve hot and enjoy this delicious and comforting meal!
Variations and Modifications
The beauty of the Ground Beef Zucchini Casserole is that it’s highly adaptable, allowing you to customize it to your taste preferences or dietary needs.
Vegetarian Version
For a vegetarian-friendly option, you can substitute the ground beef with your favorite plant-based protein, such as crumbled tofu, lentils, or a meat-alternative ground product.
Low-Carb Modifications
To make a low-carb version of the casserole, you can replace the zucchini with riced cauliflower or thinly sliced eggplant. This will reduce the carbohydrate content while still providing a delicious and satisfying meal.
Dairy-Free Alternatives
If you’re lactose intolerant or following a dairy-free diet, you can use dairy-free cheese alternatives or omit the cheese altogether and top the casserole with a creamy, dairy-free sauce, such as a cashew-based sauce or a vegan Béchamel.
Spice It Up
For those who enjoy a little heat, you can add a sprinkle of crushed red pepper flakes or a dash of hot sauce to the ground beef mixture. You can also experiment with different herbs and spices, such as chili powder, cumin, or smoked paprika, to give the casserole a unique flavor profile.

Tips for Perfecting Your Ground Beef Zucchini Casserole
Choosing the Right Zucchini
When selecting zucchini for your casserole, look for firm, vibrant green zucchinis that are free of blemishes or soft spots. Avoid overly large zucchinis, as they tend to be more watery and less flavorful.
Storing Leftovers
If you have any leftover Ground Beef Zucchini Casserole, store it in an airtight container in the refrigerator for up to 4 days. To reheat, simply place a portion in the oven or microwave until heated through.
Reheating Tips
When reheating the casserole, you may want to cover it with foil to prevent the top from drying out. If the casserole seems a bit dry, you can add a splash of marinara sauce or a sprinkle of water before reheating.
