Ingredients

• 1 cup heavy cream
• 2 cloves garlic, minced
• 1 large sweet onion
• 2 medium yellow squash
• 1 cup shredded Parmesan cheese
• 2 medium zucchini
• 2 tablespoons salted butter
• 0.5 teaspoon ground black pepper
• 0.5 teaspoon salt
• 1.5 cups shredded smoked Gouda cheese
• 0.5 cup whole-milk ricotta cheese
• 0.5 cup chopped cooked bacon

Recipe Instructions

Step 1

Preheat the oven to 450 degrees F (230 degrees C).

Step 2

Slice onion into thin rounds. Slice zucchini and yellow squash into 1/4-inch rounds.

Step 3

Melt butter in an oven-proof skillet over medium heat. Add onion slices and cook until soft and translucent, about 5 minutes. Add garlic and cook until softened, 2 to 3 minutes. Add cream and ricotta cheese; stir and simmer until bubbly and starting to thicken, 3 to 5 minutes.

Step 4

Slowly stir in Parmesan cheese. Add zucchini and summer squash and gently stir to combine. Cook for just a few minutes then sprinkle with bacon. Spread Gouda cheese evenly over the bacon and top with salt and pepper.

Step 5

Transfer skillet to the preheated oven and bake until cheese is deep golden brown on top and squash is tender, about 20 minutes. If squash needs more cooking time, cover the skillet with foil so the top crust doesn't get too dark.
