Ingredients

• 4 medium-sized yellow squash
• 3 tablespoons unsalted butter
• 1 large yellow onion
• 2 cloves garlic cloves
• 1 teaspoon fresh thyme leaves
• 1.5 cups Gruyere cheese, grated
• 1 cup heavy cream
• 0.5 cup panko breadcrumbs
• 1 tablespoon olive oil
• 1 teaspoon kosher salt
• 0.5 teaspoon black pepper
• 0.25 cup Parmesan cheese, grated

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a 9x9-inch baking dish and set aside.

Step 2

Wash and trim the ends of the yellow squash. Slice them into thin, even rounds about 1/4-inch thick.

Step 3

Heat 2 tablespoons of butter in a large skillet over medium heat.

Step 4

Add the sliced onions and cook slowly, stirring occasionally, until they are caramelized, about 10-12 minutes.

Step 5

Add the minced garlic and thyme to the onions, cooking for another 1-2 minutes until fragrant. Remove from heat.

Step 6

Layer half of the squash slices into the prepared baking dish. Sprinkle with half of the caramelized onion mixture, 3/4 cup of Gruyere cheese, and a pinch of salt and pepper.

Step 7

Repeat the layers with the remaining squash, onion mixture, and another 3/4 cup of Gruyere cheese. Finish with a sprinkling of salt and pepper.

Step 8

Pour the heavy cream evenly over the layered squash and cheese in the baking dish.

Step 9

In a small bowl, combine the panko breadcrumbs, 1 tablespoon of olive oil, 1/4 cup of Parmesan cheese, and a pinch of salt. Mix well.

Step 10

Sprinkle the breadcrumb mixture evenly over the top of the casserole.

Step 11

Melt the remaining 1 tablespoon of butter and drizzle it over the breadcrumbs.

Step 12

Bake the casserole in the preheated oven for 35-40 minutes, or until the top is golden brown and the cream is bubbling around the edges.

Step 13

Remove from the oven and let cool for 5-10 minutes before serving.
