Ingredients

  • 2 pounds yellow squash sliced ¼ inch thick (about 5 medium sized squash)
  • ¼ cup butter
  • ½ cup diced onion
  • ½ teaspoon garlic powder
  • ¾ teaspoon salt
  • ½ teaspoon black pepper
  • ½ cup sour cream
  • 1 large egg beaten
  • 1 cup shredded cheddar cheese
  • ½ cup grated Parmesan cheese
  • 1 cup butter crackers finely crushed ( about 25 crackers )

Instructions

  • In a large pan set over medium heat, melt 1 Tablespoon of butter. Add the ½ cup of onion to the pan and sauté for 7 - 8 minutes, or until soft and translucent.
  • Add the 2 lbs of sliced squash to the pan and cook for 10 - 12 min, or until the squash is soft. Stir frequently to prevent browning and to promote moisture release.
  • Place a towel in a colander so your squash doesn't slip through the holes, and place the cooked squash and onions on top of the towel to drain. Drain for at least 5 min, pressing any extra moisture out.
  • Stir together the drained squash and onion, ½ teaspoon garlic powder, ¾ teaspoon salt, ½ teaspoon ground black pepper, ½ cup sour cream, 1 beaten egg, 1 cup shredded cheddar cheese, and ¼ cup of the shredded parmesan. You'll use the rest of the parmesan in the next step.
  • Melt remaining 3 Tablespoons of butter. Stir melted butter and remaining ¼ cup parmesan cheese into crushed crackers.
  • Scrape the squash mixture into a 1.5 qt baking dish (8x8 square or similar)
  • Sprinkle the butter and cracker mixture evenly over the top of the dish.
  • Bake at 350 F for 25 min.
