Ingredients
Method
Preheat the oven to 375°F (190°C).
In a large skillet over medium heat, add olive oil. Sauté the sliced onion and minced garlic until softened, about 5-7 minutes.
In a large baking dish, arrange half of the sliced zucchinis in an even layer at the bottom.
Layer half of the sliced tomatoes on top of the zucchinis, then sprinkle with half of the sautéed onion and garlic mixture.
Season the layers with salt, pepper, half of the chopped basil, oregano, and red pepper flakes if using.
Repeat the layers with the remaining zucchinis, tomatoes, onion, garlic, and seasonings.
Finish the top layer with shredded mozzarella cheese and sprinkle breadcrumbs evenly over the cheese for added crunch.
Cover the dish with foil and bake for 25-30 minutes. Remove the foil and bake for an additional 15-20 minutes until the cheese is bubbly and the top is golden brown.
Once done, let the casserole sit for about 5 minutes before serving. Garnish with extra fresh basil leaves.
