Ingredients
 

  • 2 lb Onions 52 Sweet Onions halved and sliced in ¼ inch slices
  • 1 ½-2 cups water
  • 2 tbsp butter divided
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • ¼ cup skim milk
  • 1 cup regular or reduced-fat shredded cheddar cheese
  • 15 regular or reduced-fat buttery round crackers
  • 1 cup regular or reduced-fat cheese crackers
  • 2 large eggs

Instructions

  • Preheat the oven to 375°.
  • In a skillet on medium-high heat, add the onions and just enough water to cover them. Bring to a low-boil and cook until tender, about 8-10 minutes. Drain in a colander. 
  • In a plastic bag, crush the round crackers and cheese crackers into a fine crumb. In a medium bowl, stir together 1 tablespoon of the butter, salt, pepper, the drained onions, milk and cheese. Fold in half of the cracker crumbs. In a small bowl, whisk and temper the eggs and with a couple tablespoons of the onion mixture. This is an important step as adding the eggs directly to the warm onion mixture can scramble them. Fold the tempered eggs into the mixture. Pour the mixture into a buttered or non-stick sprayed 2-quart baking dish. Bake 30 minutes. 
  • In a small bowl, stir together the remaining butter, melted, and cracker mixture. Carefully remove the casserole from the oven, and sprinkle the mixture evenly on top. Bake an additional 15 minutes or until bubbling and lightly browned.
