Ingredients

• 4 medium-sized yellow squash
• 1 small onion
• 2 cloves garlic
• 2 tablespoons unsalted butter
• 1 cup breadcrumbs
• 1 cup cheddar cheese
• 0.5 cup parmesan cheese
• 0.5 cup sour cream
• 1 large egg
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 1 tablespoon olive oil
• 1 tablespoon fresh parsley

Directions

Step 1

Preheat the oven to 375°F (190°C) and lightly grease a 9x9-inch baking dish with olive oil or cooking spray.

Step 2

Wash the yellow squash and slice them thinly into 1/4-inch rounds. Dice the onion and mince the garlic.

Step 3

In a large skillet over medium heat, melt the butter. Add the diced onion and sauté for 3-4 minutes, or until translucent. Add the minced garlic and cook for an additional 1 minute.

Step 4

Add the sliced yellow squash to the skillet and cook for 5-6 minutes, stirring occasionally, until they start to soften. Season with salt and black pepper. Remove from heat and let cool slightly.

Step 5

In a large mixing bowl, whisk together the sour cream, egg, 1/2 cup of cheddar cheese, 1/4 cup of parmesan cheese, and the cooled squash mixture. Stir until well combined.

Step 6

Pour the squash mixture into the prepared baking dish and spread it out evenly.

Step 7

In a small bowl, mix together the breadcrumbs, the remaining 1/2 cup of cheddar cheese, 1/4 cup of parmesan cheese, and the chopped fresh parsley. Drizzle 1 tablespoon of olive oil over the breadcrumb mixture and toss to combine.

Step 8

Sprinkle the breadcrumb topping evenly over the casserole.

Step 9

Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and the casserole is bubbling around the edges.

Step 10

Remove from the oven and let the casserole cool for 5 minutes before serving. Garnish with additional parsley if desired.
