Vegetables
- 1 small onion, sliced
- 2 pounds squash (yellow squash and zucchini), sliced into ¼-inch slices
For Cooking
- 1 tablespoon butter
- 1 tablespoon olive oil
- ½ teaspoon Italian seasoning
- Salt and pepper to taste
Topping
- 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 ensure it reaches the right temperature for baking the casserole evenly.
- Prepare squash: Slice the yellow squash and zucchini into ¼-inch thick slices to allow them to cook evenly and maintain a tender texture.
- Sauté onions and squash: In a large skillet, heat 1 tablespoon of butter and 1 tablespoon of olive oil over medium heat. Add the sliced onion and cook until tender. Increase heat to medium-high, then add the sliced squash along with Italian seasoning, salt, and pepper. Cook for 5 to 6 minutes, stirring occasionally, until the squash is just tender-crisp.
- Arrange in baking dish: Grease a 2-quart baking dish. Arrange the cooked squash and onions in the dish with the squash standing on its side to create an attractive layered presentation.
- Prepare topping: In a small bowl, mix together the seasoned bread crumbs, grated Parmesan cheese, shredded cheddar cheese, and melted butter until well combined.
- Apply topping and bake: Sprinkle the breadcrumb and cheese mixture evenly over the arranged squash and onion. Bake in the preheated oven for 35 to 40 minutes, or until the squash is tender and the topping is golden brown and crispy.
Notes
- You can use all yellow squash, all zucchini, or a mix depending on your preference.
- For a crunchier topping, add more bread crumbs or a handful of crushed crackers.
- To make it vegetarian, ensure the cheese and butter used are free from animal rennet and are suitable for vegetarians.
- This casserole pairs well with grilled meats or as a hearty vegetarian main dish.
- Leftovers can be refrigerated for up to 3 days and reheated in the oven to retain crispness.
