Ingredients

  • 6 medium-sized potatoes
  • 2 medium-sized onions
  • 1 cup sharp Cheddar cheese
  • 4 eggs
  • 1 cup milk
  • 1 teaspoon salt
  • 1/2 teaspoon pepper

Instructions

  2. Beat the eggs and add milk, salt, and pepper.
  3. Pour the egg mixture over the potato, onion, and cheese mixture.
  4. Bake at 325°F (163°C) for about 1 hour until golden and set.

Tips & Substitutions

For a creamier texture, consider adding a dollop of sour cream or Greek yogurt to the egg mixture. If you prefer a lighter version, substitute half of the potatoes with cauliflower. Feel free to use different cheese varieties like Monterey Jack or Gouda for a unique flavor. To ensure even cooking, slice potatoes and onions evenly.

Serving Suggestions

This casserole pairs beautifully with a fresh salad, such as Hidden Valley Ranch Vegetables, for a balanced meal. Serve it alongside grilled meats or as a standalone dish for brunch. For added flavor, top with fresh herbs like chives or parsley before serving.

Storage & Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place in a preheated oven at 350°F (175°C) until warmed through, about 20-25 minutes. You can also microwave individual portions, covered, for a quick meal.
