Vegetables
- 1 small onion, sliced
- 2 pounds squash (yellow squash and zucchini), sliced into ¼-inch slices
Cooking Fats & Seasonings
- 1 tablespoon butter
- 1 tablespoon olive oil
- ½ teaspoon Italian seasoning
- Salt and pepper to taste
Toppings
- ⅓ cup seasoned bread crumbs
- ¼ cup grated Parmesan cheese
- ¼ cup shredded cheddar cheese
- 2 tablespoons melted butter
- Preheat Oven: Preheat your oven to 350°F (175°C) to prepare for baking the casserole later.
- Slice Squash: Slice both yellow squash and zucchini into ¼-inch thick slices to ensure even cooking and tenderness.
- Sauté Onion and Squash: In a large skillet over medium heat, cook the sliced onion in butter and olive oil until tender. Then increase the heat to medium-high, add the sliced squash, Italian seasoning, salt, and pepper, and cook for 5 to 6 minutes until the squash is just tender-crisp.
- Arrange Squash in Baking Dish: Grease a 2-quart baking dish and arrange the cooked squash and onions so that the squash slices stand on their sides, creating an attractive layered casserole.
- Prepare Topping: In a small bowl, combine the seasoned breadcrumbs, grated Parmesan cheese, shredded cheddar cheese, and melted butter. Sprinkle this mixture evenly over the top of the arranged squash and onions.
- Bake the Casserole: Place the casserole in the preheated oven and bake for 35 to 40 minutes, or until the squash is tender and the topping is golden brown and bubbly.
Notes
- Use a mix of yellow squash and zucchini for color and flavor variation.
- For a crispier topping, broil for 1-2 minutes at the end of baking, watching carefully to avoid burning.
- Seasoned breadcrumbs add extra flavor, but plain breadcrumbs with added herbs can be substituted.
- This casserole pairs well with grilled meats or as a vegetarian main dish.
- Leftovers can be refrigerated for up to 3 days and reheated in the oven for best texture.
