This Fairfax Breakfast Sandwich is a delicious egg-centric morning treat inspired by the famous Eggslut recipe. Featuring buttery brioche buns, perfectly cooked eggs, caramelized onions, creamy sriracha mayo, and melted cheddar cheese, this sandwich is packed with flavor and perfect for an indulgent breakfast or brunch.

Ingredients

Buns and Cheese

  • 2 Brioche Buns
  • 2 slices Cheddar Cheese

Eggs and Onion

  • 6 large Eggs
  • 2 White Onions
  • 4 tbsp Butter

Spicy Mayo

  • 1 cup Mayonnaise
  • 2 tbsp Sriracha Sauce
  • 2 tsp Chives

Instructions

  1. Caramelize the Onions: Peel and thinly slice the white onions. In a skillet over medium heat, melt 2 tablespoons of butter and add the onions. Cook slowly for about 20-25 minutes, stirring occasionally until the onions are soft, caramelized, and golden brown. Remove from heat and set aside.
  2. Prepare the Spicy Mayo: In a small bowl, combine the mayonnaise, Sriracha sauce, and chopped chives. Mix well and refrigerate until ready to use.
  3. Cook the Eggs: In the same skillet, melt the remaining 2 tablespoons of butter over medium heat. Crack the eggs into the pan and cook them gently to your preference—soft scrambled or sunny side up works best. Season with salt and pepper. Alternatively, create a creamy, soft scrambled style to mimic the original Fairfax sandwich texture.
  4. Toast the Buns: Slice the brioche buns in half and toast them lightly in a separate pan or under a broiler, until golden brown and slightly crisp.
  5. Assemble the Sandwich: Spread a generous layer of the prepared spicy mayo on both halves of the toasted brioche buns. Layer the caramelized onions on the bottom bun, then add the cooked eggs. Place a slice of cheddar cheese on top of the eggs so it slightly melts from the residual heat. Finish with the top bun.
  6. Serve Immediately: Serve your Fairfax Breakfast Sandwich warm for the best taste and texture. It pairs wonderfully with fresh fruit or breakfast potatoes.

Notes

  • For extra creaminess, you can add a slice of avocado or an additional layer of melted cheese.
  • Use a non-stick skillet to make egg cooking easier and avoid sticking.
  • Adjust the Sriracha amount in the mayo to your preferred spice level.
  • Caramelizing onions takes time but adds a rich sweetness critical to the sandwich’s flavor profile.
  • This sandwich is best eaten fresh but leftovers can be stored wrapped in foil for up to 1 day.
