How to Make Ground Beef Zucchini Bake

Prepare the zucchini

Slice the zucchini into rounds and sprinkle lightly with salt. Let it sit for a short time, then pat it dry with paper towels. This helps remove excess moisture so the finished bake is not watery.

Cook the vegetables

Preheat the oven to 400°F. Heat the olive oil in a large skillet over medium-high heat.

Add the diced onion and sauté for 2–3 minutes. Add the mushrooms and cook for another 4–5 minutes, until softened. Season with salt, garlic powder, and onion powder, then transfer the vegetables to a plate.

Brown the beef

Using the same skillet, add the ground beef. Break it apart with a wooden spoon and cook until no longer pink.

Season the beef with salt, garlic powder, onion powder, and paprika. Stir well and taste, adjusting the seasoning if needed.

Assemble the casserole

Place the zucchini, sautéed vegetables, cooked beef, marinara sauce, 1 cup of mozzarella, and Italian herbs in a 9×13-inch baking dish. Add black pepper and extra salt if needed, then gently mix everything together.

Sprinkle the Parmesan cheese over the top.

Bake

Bake for 30 minutes. Remove the dish from the oven and sprinkle the remaining mozzarella over the casserole.

Return it to the oven and bake until the cheese is fully melted and bubbling. Allow the bake to rest for a few minutes before serving.

Recipe Tips

• Pat the zucchini dry thoroughly to help prevent excess liquid.
• Use a thick marinara sauce for the best consistency.
• Drain the beef if it releases a large amount of fat.
• For extra flavor, add crushed red pepper flakes or fresh basil.
• Substitute ground turkey or chicken for a lighter version.
• For a richer casserole, use a combination of mozzarella and provolone.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 3–4 days. Reheat individual portions in the microwave or warm the casserole in a covered oven-safe dish until heated through.hungryhappens
