Ingredients

• 6 cups yellow squash
• 1 cup onion, diced
• 4 tablespoons butter
• 1 cup sour cream
• 1.5 cups cheddar cheese, shredded
• 1 large egg, beaten
• 1.5 cups crackers, crushed (such as Ritz)
• 0.5 cups Parmesan cheese, grated
• 0.5 teaspoons salt
• 0.25 teaspoons black pepper
• 0.25 teaspoons garlic powder
• 2 tablespoons olive oil or additional melted butter (for topping)

Directions

Step 1

Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish.

Step 2

In a large pot, bring water to a boil. Add the yellow squash and cook until just tender, about 7-8 minutes. Drain well using a colander and set aside to cool slightly.

Step 3

In a large skillet, melt 2 tablespoons of butter over medium heat. Add the diced onion and cook until softened and translucent, about 5 minutes.

Step 4

In a large mixing bowl, combine the cooked squash, sautéed onion, sour cream, cheddar cheese, beaten egg, salt, black pepper, and garlic powder. Mix well until all ingredients are evenly combined.

Step 5

Pour the squash mixture into the prepared baking dish, spreading it out into an even layer.

Step 6

In a small bowl, mix the crushed crackers, grated Parmesan cheese, and remaining 2 tablespoons of melted butter or olive oil. Sprinkle this topping evenly over the casserole.

Step 7

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

Step 8

Remove from the oven and let cool slightly for 5-10 minutes before serving. Enjoy your Holiday Squash Casserole!
