Recipe Information
Ingredients
- 4 cups (sliced) yellow squash
- 1 cup (chopped) onion
- 3 tablespoons butter
- 1 large egg
- 1 cup sour cream
- 1 cup shredded cheddar cheese
- 1 cup (crushed) Ritz crackers
- 0.5 cup (grated) parmesan cheese
- 0.5 teaspoon granulated garlic
- 1 teaspoon salt
- 0.5 teaspoon black pepper
- 1 spray (for greasing) olive oil spray
Instructions
Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with olive oil spray and set aside.
In a large skillet over medium heat, melt the butter. Add the chopped onion and saute until it becomes soft and translucent, about 5 minutes.
Add the sliced yellow squash to the skillet with the onion. Season with salt, black pepper, and granulated garlic. Cook for 8-10 minutes, stirring occasionally, until the squash is tender and any excess liquid is evaporated.
Remove the skillet from the heat and allow the mixture to cool slightly. In a large mixing bowl, beat the egg, then stir in the sour cream and shredded cheddar cheese until well combined.
Fold the cooked squash and onion mixture into the sour cream and cheese mixture until evenly coated.
Pour the mixture into the prepared baking dish, spreading it out evenly.
In a small bowl, mix the crushed Ritz crackers with grated Parmesan cheese. Sprinkle this mixture evenly over the top of the casserole.
Bake the casserole in the preheated oven for 25-30 minutes, or until the topping is golden brown and the casserole is bubbly.
Remove the casserole from the oven and let it sit for 5 minutes to cool slightly. Serve warm and enjoy!
