Ingredients

Scale

Caramelized Onions

  • 1 tbsp cooking oil
  • 1 medium yellow onion, sliced
  • 1/4 cup water
  • 1 tbsp unsalted butter
  • Pinch of salt

Scrambled Eggs

  • 3 large eggs
  • 1 tbsp unsalted butter
  • 2 tbsp chives, thinly sliced
  • Salt and pepper, to taste

Sriracha Mayo Sauce

  • 2 tbsp mayonnaise
  • 1 tbsp Sriracha

Assembly

  • 1 brioche bun, sliced
  • 2 tbsp unsalted butter, divided for toasting
  • 1 slice cheddar cheese

Instructions

  1. Caramelize the onion: In a skillet over medium heat, add cooking oil and sliced onions along with a pinch of salt and 1 tablespoon of butter. Spread the onions in a single layer and reduce heat to low. Cook, stirring often, until onions soften and turn lightly golden. Add 1/4 cup water to deglaze the pan, then continue cooking until onions are fully caramelized. Keep warm.
  2. Scramble the eggs: Crack 3 eggs into an unheated skillet and use a spatula to scramble them until blended. Add 1 tablespoon of butter and place the skillet over medium-low heat. Stir continuously while cooking, seasoning with salt and chives. Cook until eggs begin to set but remain soft. Remove from heat and keep warm.
  3. Make the sauce: In a small bowl, combine 2 tablespoons mayonnaise with 1 tablespoon Sriracha in a 2:1 ratio. Mix thoroughly to create a spicy mayo sauce.
  4. Toast the brioche bun: Spread butter on both cut sides of the brioche bun. Toast them in a skillet until golden and crisp.
  5. Assemble the sandwich: Spread the sriracha mayo on both toasted bun halves. Place the scrambled eggs on the bottom bun, then melt a slice of cheddar cheese slightly in a nonstick pan and add on top of the eggs. Finish by topping with 1-2 tablespoons of caramelized onions. Cover with the top bun and serve immediately.

Notes

  • Use low heat to caramelize onions slowly for better sweetness and texture.
  • Scrambled eggs should be creamy and just set, not overcooked.
  • Sriracha mayo can be adjusted to preferred spiciness level.
  • Additional toppings like avocado or bacon can be added for extra flavor.
  • For a vegetarian version, omit any meat additions and keep as is.
