Loaded with caramelized onions, melted cheese, and creamy scrambled eggs all wrapped together in buttery brioche buns, this Eggslut Breakfast Sandwich the ultimate way to elevate your morning. This is a copycat recipe of the iconic Eggslut chain and their most popular sandwich, the Fairfax.
What is Eggslut and where did it originate?
Eggslut, based in Los Angeles, California, is a popular food chain with locations now spanning across the globe. They are known for their egg-based sandwiches, in which the iconic name indicates.
The most notable elements of their sandwiches are the buttery brioche buns, as well as the soft slow-cooked scrambled eggs that are blended into the melted cheese, that instantly melts in your mouth in each bite.
I had the opportunity to try out these sandwiches in their location in Seoul, South Korea, and was immediately blown away. Eggslut and Eggdrop, which still holds itself to be one of the most popular recipes on my blog, were both incredibly popular in Korea, but with their own unique flavor notes.
The Fairfax Breakfast Sandwich
The recipe I will be sharing with you today is for their most popular menu item, the Fairfax sandwich. As their official website indicates, it consists of “cage-free soft scrambled eggs and chives, cheddar cheese, caramelized onions and sriracha mayo in a warm brioche bun”. Truly heaven in a sandwich.
This sandwich is truly the perfect blend of sweet and savory, where the natural sweetness of the caramelized onions and soft and creamy scrambled eggs come together to create a magical flavor combination. The sriracha mayo and the cheese then add to the rich and savory taste, which is then wrapped together in brioche buns toasted with butter.

Tips to make the best Eggslut Sandwich
- Set aside enough time to caramelize the onions. Caramelization is a process to slowly cook onions over a long period of time to let the natural sugars in the onions caramelize. The result is an intensely flavorful batch of caramelized onions, which can be used to garnish a variety of dishes like sandwiches, burgers, soups, steaks, and salads.
- Feel free to double or triple the portion in case you want to store a batch for future use. They can be stored in an airtight container in the fridge for up to 1 week, or frozen for up to 3 months to upgrade your dishes.
- Butter, butter, butter! This is the key component to this recipe, which will be used to caramelize the onions, scramble the eggs, as well as toast the brioche buns to a light golden finish. Having your butter dish available throughout your cooking session will be very useful.
- Slowly scramble the eggs on low heat, stirring continuously for the entire duration. One of the highlights of this recipe is the slow-cooked scrambled eggs that have that soft melt-in-your-mouth texture. Keep a close eye on your eggs and be careful not to overcook. The video tutorial should give you a visual reference of the preferred consistency.
- Use a non-stick pan to slightly melt the cheese when assembling. The heat of the eggs and onions will fully melt the cheese upon serving, for that perfect melt-in-the-mouth texture!
- Enjoy it fresh while it’s hot! This sandwich does not microwave well unless you want a soggy, sad sandwich. You could make the caramelized onions in advance, but I suggest serving everything fresh to achieve the ideal texture. Brew your tea or coffee in advance to sit back and enjoy the sandwich once it’s completed! Good company is always a good addition.
