Ingredients

For Breakfast Sandwich

  • 6 eggs
  • ½ cup egg whites (about 4 egg whites)
  • 1 tablespoon milk or milk alternative
  • ¼ teaspoon salt
  • ¼ teaspoon pepper
  • 4 whole-grain English muffins, sliced in half
  • 4 tablespoons pesto (homemade or store-bought)
  • ½ cup shredded mozzarella cheese
  • Fresh tomato slices (optional)

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C). Prepare an 8×8 inch baking dish by lining it with parchment paper or spraying it thoroughly with cooking spray to prevent sticking.
  2. Prepare Egg Mixture: In a medium bowl, whisk together the 6 whole eggs, ½ cup egg whites, 1 tablespoon milk, ¼ teaspoon salt, and ¼ teaspoon pepper until well combined.
  3. Bake Eggs: Pour the egg mixture into the prepared baking dish. Bake in the oven for 15 minutes or until the eggs are fully cooked through and no longer runny in the center.
  4. Cool and Cut Eggs: Remove the baking dish from the oven and allow the egg layer to cool for several minutes. Once cool, carefully lift the egg from the pan by the parchment paper and cut into four equal squares, or use a circular cookie cutter or mason jar lid to cut out four circles for a perfect fit.
  5. Assemble Sandwiches: Place each egg square or circle on the bottom half of each English muffin. Spread 1 tablespoon of pesto evenly over each egg. Distribute the shredded mozzarella cheese evenly on top of the pesto, add fresh tomato slices if desired, then cover with the top half of the English muffin.
  6. Warm or Store: To serve immediately, bake the assembled sandwiches in the oven at 350°F for 5-10 minutes until the cheese melts and the English muffins become slightly crispy. Alternatively, wrap the sandwiches in parchment or wax paper and place in a resealable freezer bag to freeze for up to one month without reheating.

Notes

  • If you have leftover homemade pesto, freeze it in ice cube trays for easy use in future meals.
  • Avoid overcooking the eggs initially; cook only until set to prevent rubbery texture after reheating.
  • Cutting the eggs into circles using a cookie cutter or jar lid helps them fit neatly inside the English muffins but cutting into squares works fine too.
  • You can substitute English muffins with bagels or sandwich thins if preferred.
  • Carton egg whites can be used instead of separating eggs to reduce waste.
  • Lining the baking pan with parchment paper makes removing the cooked eggs easier.
  • For best results, thaw frozen sandwiches in the refrigerator overnight before reheating.
  • To reheat in the microwave, unwrap the sandwich, wrap it in a paper towel, defrost on 50% power for 1 minute, then cook on high for 30 seconds to 1 minute until warm.
  • To reheat in the oven or toaster oven, heat at 350°F for about 10 minutes until warmed through.
