How to Make Ground Beef Zucchini Bake
-
Slice Zucchini: Begin by slicing the zucchini into thin rounds, about 1/4 inch thick. Place them on paper towels and sprinkle with salt; let them sit for 10-15 minutes to draw out excess moisture. Pat them dry before using.
-
Sauté Aromatics: In a large skillet, heat a drizzle of olive oil over medium heat. Add the diced onions and minced garlic, sautéing until they become softened and fragrant, about 3-4 minutes.
-
Brown the Beef: Add the ground beef to the skillet, breaking it up with a spatula. Cook until it’s nicely browned and no longer pink, which should take about 5-7 minutes.
-
Simmer the Sauce: Stir in the tomato sauce, Italian seasoning, salt, and pepper to the skillet. Let this mixture simmer for 5-7 minutes until it’s well combined and flavors meld.
-
Preheat the Oven: While the sauce simmers, preheat your oven to 375°F (190°C) and grease a 9×13 inch baking dish with a little olive oil or cooking spray.
-
Layer the Ingredients: Start layering the dish by placing half of the zucchini rounds at the bottom of the greased baking dish. Spread half of the beef mixture on top, then repeat with the remaining zucchini and beef.
-
Add Cheese: Generously sprinkle shredded mozzarella cheese on top of the final beef layer, ensuring it’s well-covered for that melty, gooey finish.
-
Bake the Casserole: Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the cheese is bubbly and golden brown, signaling that everything is cooked through.
-
Cool and Serve: Allow the Ground Beef Zucchini Bake to cool for about 5 minutes before slicing into squares. This helps the casserole set and makes for easier serving.
Optional: Garnish with fresh parsley for a pop of color and added flavor.

- Freezer: You can freeze portions for up to 3 months. Wrap tightly with plastic wrap and aluminum foil to prevent freezer burn.

Expert Tips for Ground Beef Zucchini Bake

- Uniform Slices: For even cooking, use a mandoline to achieve consistent zucchini thickness. This helps everything bake evenly and ensures the best texture.

- Layering Technique: Press down slightly on each layer as you build your casserole. This compacting allows the flavors to meld beautifully while baking.
Ground Beef Zucchini Bake Recipe FAQs
What type of zucchini is best for this recipe?
For the best results in your Ground Beef Zucchini Bake, I recommend using medium-sized zucchinis. Avoid large or seedy zucchinis, which can be watery and detract from the dish’s texture. Thinly slice the zucchini for even cooking and perfect layering.
How should I store leftovers?
Store any leftover Ground Beef Zucchini Bake in an airtight container in the refrigerator for up to 4 days. It’s best to allow the dish to cool completely before sealing it. This helps maintain its delicious texture, ensuring each serving is just as enjoyable as the first!

If you find your Ground Beef Zucchini Bake is watery, it may be due to not salting the zucchini beforehand. Salting helps to draw out excess moisture.

If it does turn out watery, try baking it longer or adjusting the temperature to help evaporate some of the liquid.
