  • 1 1/2 teaspoons salt

    divided

Directions

  1. 1

    Preheat oven to 350°F. Grease an 9"x9" pan or 2 quart baking dish with butter or cooking spray.

    Melt 2 tablespoons of the butter in a large skillet over medium-high heat. Add the sliced squash and chopped onion to the skillet. Season with 1 teaspoon of the salt. Cook until the squash is tender, about 10 minutes. Gently stir occasionally. Pour in a colander to drain any excess moisture.

  4. 4

    Fold the cooked squash and onions into the creamy mixture. Once combined, fold the whisked egg into the mixture. Pour into the prepared baking dish.

  5. 5

    Melt the remaining butter in a medium mixing bowl. Combine with crushed crackers and remaining cheeses. Evenly distribute on top of the squash base.

  6. 6

    Bake in the preheated oven 20-25 minutes, or until bubbly and golden brown.
