Step‑by‑Step Instructions for Eggslut Breakfast Sandwich
Step 1: Caramelize Onions
Begin by melting 2 tablespoons of butter in a skillet set over medium heat. Once the butter is bubbling, add thinly sliced onions. Stir occasionally for about 15-20 minutes, allowing the onions to become golden brown and fragrant. The longer you cook them, the sweeter they become, transforming into a lovely caramelized topping for your Eggslut Breakfast Sandwich.
Step 2: Prepare Eggs
While the onions are caramelizing, crack 4 large eggs into a bowl and whisk them together with 2 tablespoons of heavy cream, salt, and pepper until combined. In a non-stick pan heated over low, gently pour the egg mixture. Cook the eggs slowly, stirring occasionally, for about 5-7 minutes, until they are soft and creamy. This will create the perfect filling for your sandwich.
Step 3: Toast Buns
In a separate pan, warm up your brioche buns. Toast them cut-side down over medium heat for about 2-3 minutes or until they are golden brown and crispy. This step enhances the texture and adds a lovely buttery flavor, making the buns a delightful cradle for your Eggslut Breakfast Sandwich.
Step 4: Assemble Sandwich
Start assembling your Eggslut Breakfast Sandwich by placing a generous portion of the scrambled eggs on the bottom half of your toasted brioche bun. Next, evenly distribute the caramelized onions over the eggs, followed by a sprinkle of shredded cheese. If you like, add fresh herbs or sliced avocado for an extra touch of flavor and creaminess, then place the top half of the bun to complete the sandwich.
Step 5: Serve Warm
Slice your Eggslut Breakfast Sandwich in half if desired, and serve immediately while warm. This delightful combination is best enjoyed fresh, letting the flavors meld together beautifully. Pair it with your favorite beverage, and savor this comforting breakfast that is sure to start your day off on the right foot!
