How to Make Zucchini & Squash Casserole

Step 1: Preheat the Oven

Preheat your oven to 350 degrees Fahrenheit. This step is crucial for ensuring that your casserole cooks evenly.

Step 2: Prepare the Vegetables

• Cut the yellow squash and zucchini into thin, ¼-inch slices.

In a mixing bowl, combine Parmesan cheese, Panko breadcrumbs, and garlic powder. Toss well before sprinkling this mixture evenly over the zucchini and squash layers.

Step 6: Bake

Cover the baking dish with aluminum foil. Place it in your preheated oven and bake for 30 minutes.

Step 7: Broil

After baking, carefully remove the foil. Switch your oven setting to High broil. Broil for an additional 5-7 minutes until the topping turns golden brown.
