Equipment
- 9x13-inch baking dish or casserole pan
- Mixing bowls & spatula
- Chef’s knife + cutting board
- Grater for zucchini and cheese
- Aluminum foil (optional)
- Oven mitts and cooling rack (optional)
Ingredients
- 3 medium zucchini, sliced or grated
- 1–2 cups shredded mozzarella cheese
- ½ cup grated parmesan cheese
- ½ cup ricotta cheese (optional, for creaminess)
- 2 cups tomato sauce (homemade or store-bought)
- 1 cup cooked protein (ground sausage, chicken, turkey, or plant-based alternative; optional)
- 1 tsp Italian seasoning
- ½ tsp garlic powder
- ½ tsp crushed red pepper flakes (optional)
- Salt & pepper, to taste
- Toppings (optional): pepperoni, mushrooms, olives, bell peppers
- Olive oil, for greasing dish if needed
Instructions
- Prepare zucchini: Slice, grate, or roast zucchini. If using sliced or grated, sprinkle with salt and let sit 10–15 minutes. Pat dry to remove excess moisture.
- Cook protein (if using): Brown sausage, chicken, or plant-based protein; drain excess fat.
- Layer casserole: Spread ½ cup tomato sauce in a 9x13-inch dish. Layer zucchini, protein, and cheese. Repeat until all ingredients are used, finishing with cheese on top. Add optional toppings.
- Bake: Preheat oven to 375°F (190°C). Cover with foil for 20–25 minutes, then uncover and bake 15–20 minutes more until cheese is bubbly and golden.
- Broil (optional): Broil 2–3 minutes for a crisp, golden cheese top. Watch closely to avoid burning.
- Cool & serve: Rest 5–10 minutes before slicing. Sprinkle with fresh basil or parmesan if desired.
Notes
- Prevent soggy casserole: Salting and draining zucchini is key.
- Make-ahead: Assemble in advance and refrigerate; bake when ready.
- Freezing: Freeze unbaked or baked portions in airtight containers up to 2 months. Reheat in oven.
- Cheese variations: Use a blend of mozzarella, parmesan, ricotta, or feta to adjust flavor and texture.
- Serving suggestions: Pair with a crisp salad, garlic bread, or roasted vegetables.
