Ingredients

Scale
  • 1.5 lbs zucchini, thinly sliced
  • 1 tsp salt
  • 2 tbsp olive oil
  • 1 small onion, chopped
  • 2 cloves garlic, minced
  • 1 cup shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese
  • 1/4 cup breadcrumbs
  • 1/4 tsp black pepper

Instructions

  1. Preheat your oven to 400°F (200°C).
  2. Toss the sliced zucchini with 1 tsp salt in a colander. Let sit for 15-20 minutes to draw out moisture. Pat dry with paper towels.
  3. Heat olive oil in a large skillet over medium heat. Add onion and cook until softened, about 5 minutes. Add garlic and cook for 1 minute more until fragrant.
  4. In a large bowl, combine the dried zucchini slices, cooked onion and garlic mixture, shredded mozzarella, grated Parmesan, breadcrumbs, and black pepper. Toss gently to coat evenly.
  5. Transfer the mixture to a greased 9×13 inch baking dish.
  6. Bake for 25-30 minutes, or until the top is golden brown and bubbly.
  7. Let stand for 5 minutes before serving.

Notes

  • Salting and draining the zucchini is key to preventing a watery casserole.
  • For an extra crispy top, you can broil for the last 1-2 minutes, watching carefully to prevent burning.
  • This bake is great for meal prep and can be reheated.
