Description

The Fairfax Breakfast Sandwich is a delicious American morning staple featuring soft, creamy scrambled eggs layered with cheddar cheese, caramelized onions, spicy mayo, and fresh avocado slices, all nestled in a lightly toasted brioche bun. This sandwich offers a perfect balance of rich flavors and creamy textures, ideal for a satisfying breakfast or brunch.


Ingredients

Scale

Sandwich Components

  • 4 brioche buns, split and lightly toasted
  • 4 slices cheddar cheese
  • 4 tablespoons caramelized onions
  • 1 avocado, sliced
  • Fresh chives (optional, for garnish)

Scrambled Eggs

  • 8 large eggs
  • ¼ cup whole milk or cream
  • 2 tablespoons unsalted butter
  • Salt and black pepper to taste

Spicy Mayo Spread

  • 4 tablespoons mayonnaise
  • 1 teaspoon Sriracha or hot sauce


Instructions

  1. Prepare the Egg Mixture: In a bowl, whisk together the 8 large eggs, ¼ cup whole milk or cream, salt, and pepper until smooth and fully combined to ensure creamy scrambled eggs.
  2. Cook the Eggs: Heat a large nonstick skillet over medium heat and melt 2 tablespoons of unsalted butter. Pour in the egg mixture and gently stir constantly with a spatula. Cook slowly, allowing soft curds to form while keeping the eggs creamy, approximately 3–4 minutes. Remove from the heat just before fully set, as the residual heat will finish cooking them.
  3. Make the Spicy Mayo: In a small bowl, combine 4 tablespoons mayonnaise with 1 teaspoon Sriracha or hot sauce, mixing well to create a flavorful spicy mayo spread.
  4. Assemble the Sandwiches: Spread a generous layer of the spicy mayo on the bottom half of each toasted brioche bun. Add 1 tablespoon of caramelized onions on top of the spicy mayo. Then layer with a portion of the scrambled eggs, followed by a slice of cheddar cheese, and finish with sliced avocado.
  5. Garnish and Serve: Optionally, sprinkle fresh chives over the avocado for a pop of color and subtle flavor. Place the top halves of the brioche buns onto each sandwich. Serve immediately while warm.

Notes

  • For extra flavor, toast the buns in butter before assembling.
  • Adding a slice of crispy bacon enhances the sandwich for non-vegetarian preferences.
  • Cook the eggs low and slow to achieve the signature soft, creamy texture.
