Ingredients
Scale
Vegetables
- 4 cups yellow squash, sliced (about 4–5 medium squash)
- 1 small onion, finely chopped
Dairy & Eggs
- 1 cup shredded cheddar cheese
- 1/2 cup sour cream
- 1/4 cup mayonnaise
- 1 egg, beaten
Seasoning & Toppings
- 1/2 teaspoon garlic powder
- Salt and pepper to taste
- 1 cup crushed Ritz crackers or buttery breadcrumbs
- 2 tablespoons melted butter
Instructions
- Preheat Oven: Preheat your oven to 350°F (175°C) and grease a 9×9 inch or similarly sized baking dish to prevent sticking.
- Sauté Vegetables: In a large skillet over medium heat, sauté the sliced yellow squash and finely chopped onion with a pinch of salt for 8–10 minutes until tender. Drain any excess liquid to avoid a watery casserole.
- Mix Ingredients: In a large bowl, combine the cooked squash and onions with shredded cheddar cheese, sour cream, mayonnaise, the beaten egg, garlic powder, salt, and pepper. Mix thoroughly to create a creamy, well-seasoned filling.
- Assemble Casserole: Transfer the squash mixture into the prepared baking dish and spread it evenly for consistent cooking and presentation.
- Prepare Topping: In a small bowl, mix the crushed Ritz crackers or buttery breadcrumbs with the melted butter until they are well coated. Sprinkle this mixture evenly over the casserole to form a crunchy, golden topping.
- Bake: Place the casserole in the preheated oven and bake for 30–35 minutes or until the top is golden brown and bubbly, indicating it is cooked through.
- Cool and Serve: Remove the casserole from the oven and let it cool for 5 minutes before serving to allow it to set and enhance flavors.
Notes
- To reduce moisture in the casserole, be sure to drain the cooked squash and onions well before mixing other ingredients.
- You can substitute the Ritz crackers with buttery breadcrumbs for a different texture.
- This dish can be made ahead and baked just before serving.
- For extra flavor, consider adding a pinch of paprika or chopped fresh herbs like parsley or thyme.
- Leftovers store well in the refrigerator for up to 3 days and can be reheated in the oven.
