Recipe Description

I love to make this Zucchini Gratin with Yellow Squash for a meat free Monday meal. The secret to this gratin recipe is smoked Gouda cheese which I use to top this baked gratin. My family loves this dish and I am sure yours will too!

To make this gratin, start by cooking onion and garlic in an ovenproof dish. Add the cream and simmer until it starts to thicken. Add Parmesan and sliced zucchini and yellow squash. Top with smoked Gouda cheese and bake in the oven until the cheese is melted and golden brown. Enjoy!
