Description
This comforting casserole is packed with fresh garden zucchini, melted cheese, and cozy flavors baked to bubbly perfection.
Ingredients
3 medium zucchini, thinly sliced
1 tablespoon olive oil or butter
1 small onion, finely diced
2 cloves garlic, minced
1/2 teaspoon salt
1/4 teaspoon black pepper
1/2 teaspoon dried Italian seasoning (or oregano + basil)
1/2 cup sour cream or Greek yogurt
1/2 cup shredded mozzarella cheese
1/2 cup shredded cheddar cheese
1/4 cup grated Parmesan cheese
1/4 cup breadcrumbs (optional, for topping)
2 tablespoons fresh parsley, chopped (for garnish)
Instructions
Preheat oven to 375°F (190°C). Grease a medium baking dish.
Heat olive oil in a skillet. Sauté onion and garlic until softened, about 3 minutes.
In a large bowl, combine zucchini slices, sautéed onion mixture, salt, pepper, Italian seasoning, and sour cream. Toss to coat evenly.
Layer zucchini mixture in the baking dish. Sprinkle mozzarella, cheddar, and Parmesan over the top.
If using, add breadcrumbs for a crunchy topping.
Bake for 25–30 minutes, until zucchini is tender and cheese is golden and bubbly.
Garnish with fresh parsley and serve warm.
Notes
Use yellow squash along with zucchini for color variety.
Make it low-carb by skipping breadcrumbs.
Add cooked chicken or ground turkey to make it a complete main dish.
Reheats well in the oven or air fryer.
