Ingredients
You’ll need just a handful of everyday ingredients:
- 4 cups yellow squash, sliced
- 1 small onion, finely chopped
- 2 tablespoons butter, plus more for topping
- 2 large eggs, beaten
- 1 cup shredded cheddar cheese
- ½ cup sour cream
- 1 sleeve (about 30) buttery round crackers, crushed
- Salt and pepper to taste
- Optional: pinch of garlic powder or paprika for a flavor boost
Step-by-Step Instructions
1. Preheat and Prepare
Preheat your oven to 350°F (175°C). Lightly grease a 9×9-inch baking dish and set it aside.
2. Cook the Vegetables
In a large skillet over medium heat, melt the butter. Add the sliced squash and chopped onion. Cook for about 10 minutes or until the vegetables are tender, stirring occasionally. Remove from heat.
3. Mix the Filling
In a large mixing bowl, combine the beaten eggs, sour cream, shredded cheddar cheese, half of the crushed crackers, and your preferred seasonings (salt, pepper, garlic powder, or paprika). Mix until well blended.
4. Add the Squash Mixture
Gently fold the cooked squash and onion into the creamy mixture. Stir until fully combined.
5. Assemble the Casserole
Pour the mixture into the greased baking dish. Spread it out evenly. Sprinkle the remaining crushed crackers on top, and dot with small pieces of butter to help create a golden, crispy topping.
6. Bake
Place the casserole in the preheated oven and bake for 25 to 30 minutes, or until the top is golden brown and the casserole is bubbling around the edges.
Cooking Tips and Variations
- For a colorful twist, swap half of the yellow squash with zucchini.
- Add a pinch of cayenne pepper if you like a touch of heat.
- You can prep the casserole a day in advance and refrigerate it. Just bake it fresh before serving.
