Ingredients You’ll Need
Main Ingredients
1 lb (450 g) ground beef
2–3 medium zucchini, sliced into rounds or thin strips
1 small onion, diced
2 cloves garlic, minced
2 cups tomato or marinara sauce
1½ cups shredded mozzarella cheese
½ cup grated Parmesan cheese
1 teaspoon Italian seasoning
Salt and black pepper to taste
1 tablespoon olive oil
Optional Add-Ins
Bell peppers or mushrooms
Spinach or kale
Red chili flakes for heat
Ricotta or cottage cheese for extra creaminess
How to Make Ground Beef Zucchini Bake
Step 1: Prepare the Zucchini
Wash and slice the zucchini into thin rounds or lengthwise strips. If the zucchini is very watery, lightly salt the slices and let them sit for 10 minutes, then pat dry with paper towels. This prevents excess moisture in the casserole.
Step 2: Cook the Ground Beef
Heat olive oil in a large skillet over medium heat. Add the onion and sauté until soft, then stir in garlic. Add the ground beef and cook until browned, breaking it up as it cooks. Drain excess fat if needed.
Step 3: Add Sauce and Seasoning
Stir the tomato sauce and Italian seasoning into the cooked beef. Season with salt and pepper. Simmer for 5–10 minutes to develop flavor.
Step 4: Assemble the Bake
Preheat the oven to 375°F (190°C). In a greased baking dish:
Spread a thin layer of meat sauce on the bottom.
Add a layer of zucchini slices.
Top with more meat sauce and a sprinkle of mozzarella.
Repeat layers until ingredients are used, finishing with cheese and Parmesan on top.
Step 5: Bake
Cover with foil and bake for 25 minutes. Remove the foil and bake another 10–15 minutes until the cheese is melted and bubbly. Let the dish rest for 10 minutes before serving.
Why Ground Beef Zucchini Bake Works So Well

Practical Tips for the Best Ground Beef Zucchini Bake
Remove Excess Moisture
Zucchini releases water during baking. Salting and patting dry helps prevent a watery casserole.
Slice Evenly
Uniform slices ensure even cooking and a better layered structure.
Let It Rest After Baking
Resting helps the layers set, making it easier to slice and serve.
Add Extra Vegetables
Bell peppers, mushrooms, or spinach increase nutrition and flavor without much extra effort.
Use Quality Cheese
Freshly grated cheese melts better and enhances overall taste.

Storage and Reheating Tips
