Zucchini Gratin with Yellow Squash

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!

Ingredients:
2 tbsp Butter
½ Onion
1 small Zucchini
1 small Summer squash
2 cloves Garlic
½ cup Heavy cream
¼ cup Parmesan cheese
1 cup Smoked Gouda

Instructions:
Preheat oven to 450 degrees
Melt butter in oven proof skillet over medium heat. Add onion and cook until the edges start to brown approximately 5 minutes. Add garlic and cook for additional 1 minute. Add cream and simmer until bubbly and starting to thicken. Slowly stir in parmesan. Add zucchini and yellow squash and cook an additional 4-5 minutes.
Sprinkle with smoked gouda and bake in the oven for 15-20 minutes or until cheese is golden brown.
