Recipe Information
Ingredients
- 6 cups yellow squash
- 1 medium, diced onion
- 1 teaspoon salt
- 4 tablespoons unsalted butter
- 2 large egg
- 1 cup sour cream
- 1 cup, shredded sharp cheddar cheese
- 2 cups, crushed Ritz crackers
- 1 cup, grated parmesan cheese
- 0.5 teaspoon black pepper
- 0.5 teaspoon garlic powder
- 1 tablespoon olive oil
Instructions
Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish lightly with cooking spray or olive oil.
In a large pot, bring salted water to a boil. Add the sliced yellow squash and diced onion, and cook for about 5 minutes, or until the squash is slightly tender. Drain the vegetables well and set aside.
In a large skillet, melt 2 tablespoons of the butter over medium heat. Add the crushed Ritz crackers and stir until they're evenly coated and lightly toasted. Remove from heat and set the crackers aside for the topping.
In a large mixing bowl, whisk the eggs. Stir in the sour cream, grated Parmesan cheese, shredded cheddar cheese, black pepper, garlic powder, and the remaining 2 tablespoons of melted butter.
Gently fold the cooked squash and onion into the cheese mixture until evenly coated.
Transfer the squash mixture into the prepared baking dish, spreading it out evenly. Sprinkle the toasted Ritz cracker topping evenly over the top.
Bake in the preheated oven for 30-35 minutes, or until the top is golden brown and the casserole is bubbling around the edges.
Allow the casserole to cool for 5-10 minutes before serving. Serve warm as a side dish for any meal.
