- 1 ½ cups of shredded cheese (mozzarella, cheddar, or a combination)
- 1 ½ lb ground meat (beef, pork, sausage without casings, chicken, turkey, or soy-based crumbles)
- ¾ cup chopped onion
- 2 cups sliced mushrooms
- ½ cup chopped peppers (green, orange, yellow, or red)
- 1 jar of your favorite pasta, tomato, or spaghetti sauce (Alfredo works as a creamy alternative!)
- 1–2 tbsp Italian seasoning (optional)
- 1 ½ cups shredded cheese (for topping, adjust to taste)
Step-by-Step: How to Make Meaty Zucchini Casserole
- Preheat & Prep: Preheat your oven to 400°F. Lightly grease a 13×9-inch baking dish with cooking spray and set aside.
- Prepare the zucchini base: Grate the zucchini and place it in a strainer. Sprinkle with salt, toss gently, and let it sit for about 15 minutes to draw out excess moisture.
- Mix the zucchini layer: In a medium mixing bowl, combine the zucchini with eggs, Parmesan cheese, and half of the shredded cheese. Stir thoroughly and spread this mixture evenly in the prepared baking dish.
- Cook the meaty layer: In a large skillet over medium heat, cook the ground meat until browned. Add onions, mushrooms, and peppers, and sauté until softened. Stir in the pasta or spaghetti sauce and Italian seasoning (if using).
- Assemble the casserole: Pour the meaty sauce mixture over the zucchini layer, spreading it evenly. Top with the remaining shredded cheese.
- Bake: Transfer the casserole to the oven and bake for 25–30 minutes, until the cheese is melted, bubbly, and golden on top.
- Cool & Serve: Let it rest for a few minutes before slicing and serving.
Helpful Tips
- Drain thoroughly: Be sure to squeeze out as much liquid as possible after salting the zucchini to avoid a watery casserole.
- Use pre-shredded cheese for convenience – Or freshly grate for extra melty goodness.
- Kick up the flavor: Add red pepper flakes or a pinch of cayenne if you like a little heat.
- Make ahead: Assemble the casserole up to the baking step, cover it, and refrigerate for up to 24 hours before baking.
Substitutions and Variations
- Meat options: Use ground turkey, chicken, or vegetarian crumbles for a lighter option.
- Cheese swap: Try ricotta, cream cheese, or feta for a different flavor profile.
- Sauce variation: Switch to Alfredo or a creamy garlic sauce for a richer casserole.
- Veggie boost: Add spinach, zucchini slices, or eggplant for extra nutrients.
Storage Instructions
- Refrigerator: Keep leftovers in an airtight container in the refrigerator for up to 4 days.
- Freezer: Wrap tightly in foil or use freezer-safe containers and freeze for up to 2 months. Thaw in the fridge overnight before reheating.
- Reheating: Warm in the oven at 350°F or microwave individual portions until heated through.
