Ingredients
  

Casserole
  • 4 cups yellow squash sliced thin
  • 1 pound Italian sausage casings removed
  • 1 small onion diced
  • 2 cloves garlic minced
  • 1 cup mozzarella cheese shredded
  • 1 cup cheddar cheese shredded
  • 1/2 cup sour cream
  • 1/2 cup mayonnaise
  • 2 large eggs
  • 1 cup buttery crackers crushed
  • 2 tablespoons butter melted
  • salt to taste
  • black pepper to taste

Equipment

  • 9x13 baking dish
  • Large Skillet
  • Mixing Bowl

Method
 

  1. Preheat your oven to 375 degrees F. Lightly grease a 9x13 baking dish.
  2. In a large skillet over medium heat, cook the Italian sausage, breaking it into small pieces until browned and no pink remains. Remove and set aside.
  3. In the same skillet, cook the sliced squash and diced onion for 8 to 10 minutes until tender and moisture has mostly evaporated. Add garlic and cook for 1 more minute.
  4. In a large bowl, whisk together eggs, sour cream, and mayonnaise. Stir in mozzarella and cheddar cheese. Season with salt and pepper.
  5. Add cooked sausage and squash mixture to the bowl. Stir gently to combine.
  6. Pour mixture into prepared baking dish and spread evenly.
  7. Mix crushed crackers with melted butter and sprinkle evenly over the top.
  8. Bake for 30 to 35 minutes until golden and center is set. Let rest for 10 minutes before serving.

Notes

Be sure to cook out excess moisture from the squash to prevent a watery casserole. You can substitute Greek yogurt for sour cream for a lighter version. Mild or spicy Italian sausage both work well.
