Ingredients
For the Casserole
-
4 cups yellow squash, sliced into ¼-inch rounds
-
½ cup chopped onion
-
1 tablespoon olive oil or butter
-
1 cup shredded cheddar cheese
-
½ cup grated Parmesan cheese
-
½ cup sour cream
-
2 large eggs
-
½ teaspoon garlic powder
-
½ teaspoon salt
-
¼ teaspoon black pepper
For the Topping
-
1 cup crushed butter crackers (like Ritz)
-
2 tablespoons melted butter
Instructions
-
Preheat the oven
Preheat your oven to 350°F (175°C) and lightly grease a 9×9-inch baking dish. -
Cook the squash and onions
Heat olive oil or butter in a skillet over medium heat. Add the sliced squash and chopped onions. Sauté for about 10–12 minutes until the squash is soft and most of the moisture has evaporated. Let cool slightly. -
Prepare the egg mixture
In a large bowl, whisk together eggs, sour cream, cheddar cheese, Parmesan, garlic powder, salt, and pepper. -
Combine squash with egg mixture
Fold the cooked squash and onions into the egg mixture. Stir gently to combine everything evenly. -
Assemble the casserole
Pour the squash mixture into the greased baking dish and spread it out evenly. -
Add topping
Mix the crushed crackers with melted butter and sprinkle over the top of the casserole. -
Bake
Bake uncovered for 30–35 minutes, or until golden brown and bubbly. -
Rest and serve
Allow to cool for 5–10 minutes before serving for best texture and flavor.
Notes
Letting the cooked squash cool before mixing helps avoid curdling the eggs. If your squash is extra watery, press with a paper towel before combining. For a crunchier top, broil for the last 2 minutes.
