Ingredients

1 tablespoon olive oil
1 medium yellow onion peeled and diced
2 cloves garlic minced
4 cups yellow squash sliced (about 2 squash)
¼ cup water
1 sleeve Ritz crackers
1 heaping cup cheddar cheese shredded
2 large eggs beaten
¾ cup 2% milk
¼ cup unsalted butter melted
1 teaspoon salt
½ teaspoon pepper
2 tablespoons unsalted butter cut into small pieces

Instructions

Preheat oven to 400 degrees F. Grease a 9-inch x 13-inch baking dish with non-stick cooking spray.
Heat 1 tablespoon olive oil over med heat in a large skillet. Sauté 1 medium yellow onion and 2 cloves garlic for 2-3 minutes.
Add 4 cups yellow squash to the skillet over the onion and pour in1/4 cup water. Cover and allow to steam for about 5 minutes, or until the squash is tender.
In a medium mixing bowl, crush 1 sleeve Ritz crackers with your hands. Add in 1 heaping cup cheddar cheese and mix until evenly combined. Set half of the cracker/cheese mixture aside in a separate bowl.
To the rest of the cracker mixture, add 2 large eggs, 3/4 cup 2% milk, and 1/4 cup unsalted butter. Add the veggies to the bowl along with 1 teaspoon salt and 1/2 teaspoon pepper.
Pour the squash mixture into the prepared baking dish and spread it out evenly. Sprinkle the top with the reserved cracker mixture and 2 tablespoons unsalted butter cut into small pieces.
Bake for 25 minutes until the cracker topping is slightly browned. Remove from the oven and let rest for 5 minutes before serving warm.

Notes

If you notice excess liquid in the skillet after cooking the squash, allow it to cook off before mixing the filling. This helps prevent a watery casserole.
If the cracker topping starts to brown too quickly, loosely cover the baking dish with aluminum foil.
