How To Make squash casserole

  • Step 1
    Preheat oven to 350 degrees. Grease a 9×13-inch casserole dish or a dish close to equivalent in size.
  • Step 2
    Melt 1½ tablespoons butter in a large skillet over medium heat. Sauté the squash just until tender. Place it in a colander in the sink to drain any excess moisture. Carefully drain or wipe the skillet of any added moisture.
  • Step 3
    Melt 1 tablespoon butter over medium heat. Add the onion and cook until tender. Reduce the heat to low and add the garlic, cooking for a minute.
  • Step 4
    In a large bowl, mix the eggs, cheddar cheese, mayonnaise, sour cream, salt, black pepper, and thyme. Gently toss the veggies in the egg mixture and spoon them into the prepared casserole.
  • Step 5
    Melt 1½ tablespoons butter. Mix the crushed crackers with the melted butter and sprinkle them over the top of the squash mixture. Bake for 25-30 minutes or until lightly browned. Let the casserole rest for 5 minutes before serving.
