- ½ teaspoon Italian seasoning

- ⅓ cup seasoned bread crumbs

Instructions
- Preheat Oven: Preheat your oven to 350°F (175°C) to prepare it for baking the casserole.
- Prepare Squash: Slice the yellow squash and zucchini into ¼-inch thick slices to ensure even cooking.
- Sauté Onions and Squash: In a large skillet over medium heat, cook the sliced onion in butter and olive oil until tender. Then increase heat to medium-high, add the sliced squash along with Italian seasoning, salt, and pepper. Cook for 5 to 6 minutes until the squash is tender-crisp.

- Bake the Casserole: Place the baking dish 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.
