• 1 cup shredded Parmesan cheese
• 1 teaspoon garlic powder
• 1/2 teaspoon onion powder

How to Make Zucchini and Yellow Squash Au Gratin

Step 1: Prep Your Ingredients

Preheat your oven to 375°F (190°C). Slice the zucchini and yellow squash into even rounds, about 1/8 inch thick. This ensures even cooking and prevents soggy spots.

Step 2: Make the Creamy Sauce

In a mixing bowl, whisk together the heavy cream, garlic powder, onion powder, salt, and pepper. Add half of the shredded Gruyere and Parmesan cheese to the mix.

Step 3: Layer the Veggies

In a greased baking dish, arrange half the zucchini and yellow squash in overlapping rows. Pour half of the creamy sauce over the veggies. Repeat with the remaining veggies and sauce.

Step 4: Add the Topping

Sprinkle the remaining Gruyere and Parmesan cheese over the top. If using breadcrumbs, mix them with the melted butter and sprinkle that over the cheese layer.

Step 5: Bake Until Golden

Cover the dish with foil and bake for 25 minutes. Remove the foil and bake for an additional 15-20 minutes, or until the top is golden and bubbly. Let it cool slightly before serving.
