Ingredients

  • 1 loaf Italian bread
  • 6 Tbsp. butter
  • 3/4 lb. Swiss cheese
  • 1/2 lb. Mozzarella cheese
  • 9 thin slices Genoa salami
  • 16 eggs
  • 3 1/4 c. milk
  • 1/2 c. white cooking wine
  • 4 green onions
  • 1 Tbsp. Dijon mustard
  • salt
  • pepper
  • 1 1/2 c. sour cream

Instructions

  1. Spray a 14 x 11-inch pan with oil.
  2. Put bread on the bottom of the pan.
  3. Drizzle melted butter over the bread.
  4. Sprinkle shredded Swiss cheese, shredded Mozzarella cheese, and chopped Genoa salami on top of the bread and butter layer.

  6. Pour the egg mixture evenly over the layered bread, cheese, and salami in the pan.
  7. Cover and refrigerate overnight to allow the bread to soak up the egg mixture.
  8. Preheat oven to 375°F (190°C).

  10. Serve hot, garnished with grated Parmesan cheese and sour cream if desired.

Tips & Substitutions

For a richer flavor, consider using aged Swiss cheese or adding fresh herbs like basil or parsley. If you prefer a lighter option, substitute half of the cream with low-fat milk. You can also experiment with different deli meats, such as prosciutto or capicola, for varied flavor profiles. This dish pairs beautifully with Italian Meat Balls With Italian Sausage for a hearty brunch.

Serving Suggestions

Serve the omelet hot, garnished with grated Parmesan cheese and a dollop of sour cream for added creaminess. Pair it with a fresh green salad or roasted vegetables for a complete meal. You might also enjoy it with toasted Italian bread or alongside Italian-Style Pasta Salad for a delightful brunch spread.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave for 1-2 minutes, or in the oven at 350°F (175°C) until warmed through. Cover with foil to prevent drying out. This makes a great make-ahead breakfast option.
