Zucchini and Yellow Squash Au Gratin (Printable Version)

# What You’ll Need:

01 - 2 tablespoons butter
02 - 1/2 onion, thinly sliced
03 - 1 small zucchini, sliced in rounds 1/8 to 1/4 inch thick
04 - 1 small yellow squash, sliced in rounds 1/8 to 1/4 inch thick
05 - 2 large cloves of garlic, minced
06 - 1/2 cup heavy cream
07 - 1/4 cup grated Parmesan cheese
08 - 1 cup shredded smoked Gouda

# Steps to Follow:

01 - Preheat oven to 450°F (232°C).
02 - Melt butter in an oven-proof skillet over medium heat. Add onion and cook until the edges begin to brown, approximately 5 minutes.
03 - Add garlic and cook for 1 minute. Pour in the heavy cream and let it simmer until bubbly and slightly thickened.
04 - Slowly stir in the Parmesan cheese until fully combined.
05 - Add the sliced zucchini and yellow squash to the skillet. Cook for 4-5 minutes, stirring occasionally.
06 - Sprinkle the shredded smoked Gouda evenly over the top. Transfer the skillet to the oven and bake for 15-20 minutes, or until the cheese is golden brown.

# Additional Notes:

01 - For larger zucchini, double the cream and Parmesan. Additional simmering or baking time may be needed as larger zucchini can be tougher.
