- Caramelized onions: Sweet, deeply golden onions bring a burst of umami and beautiful flavor complexity.
- Sharp cheddar cheese (shredded): Melts perfectly into the eggs and delivers a wonderful tangy bite.
- Sriracha mayo: Creamy with a spicy kick, this spread wakes up all the flavors and adds some fun heat.

How to Make Fairfax Breakfast Sandwich
Step 1: Toast the Brioche Buns
Begin by splitting your brioche buns and toasting them until beautifully golden and slightly crisp at the edges. This not only adds texture, but helps the buns stand up to all those luscious fillings without getting soggy.
Step 2: Prepare the Soft Scrambled Eggs
Crack the eggs into a bowl, season with salt and pepper, and give them a good whisk until everything is well blended. In a nonstick skillet, melt your butter over medium-low heat, pour in the eggs, and stir steadily (use a silicone spatula for best results). Slow, gentle movement is key here—your goal is silky, soft curds. Once the eggs are just set but still creamy, remove the pan from the heat and fold in your shredded cheddar cheese. The warmth will melt everything together into dreamy, cheesy eggs.
Step 3: Dress the Buns with Sriracha Mayo
Grab your toasted buns and generously spread sriracha mayo on both cut sides. This creamy-spicy layer is what gives the Fairfax Breakfast Sandwich its signature kick, so don’t be shy!
Step 4: Layer Up Your Sandwich
Time for the fun part! Start with a layer of caramelized onions on the bottom bun, spoon on a heaping mound of your cheesy scrambled eggs, and carefully fan out your avocado slices over the top. Finish with the top bun (sriracha mayo side down, of course).
Step 5: Serve and Enjoy
Serve your Fairfax Breakfast Sandwich warm while the eggs are still melty and the buns are toasty. Each bite is loaded with creamy, cheesy, spicy, and sweet flavors that will jump-start any morning.
How to Serve Fairfax Breakfast Sandwich

Garnishes
For an extra flourish, sprinkle a few freshly chopped chives or a pinch of flaky sea salt over the eggs before closing the sandwich. A little fresh-cracked black pepper on top also makes every bite pop.
Side Dishes
The Fairfax Breakfast Sandwich shines even brighter next to crispy hash browns, a tangle of simple greens, or slices of juicy orange. A hot cup of coffee or a fresh-pressed juice rounds out the perfect breakfast spread.
Creative Ways to Present
Try wrapping each sandwich in parchment paper for a café-style vibe, or serve open-faced with the eggs and avocado on top for a weekend brunch centerpiece. Cut into halves or thirds for a shared platter at gatherings—mini Fairfax Breakfast Sandwiches are always a hit!
Make Ahead and Storage
Storing Leftovers
Wrapped tightly, leftovers will keep in the fridge for up to 24 hours. The scrambled eggs and avocado are best eaten fresh, but refrigerated sandwiches still make a delicious (and quick) breakfast the next day.
Freezing
While the Fairfax Breakfast Sandwich is at its best when fresh, you can freeze assembled sandwiches (minus avocado) wrapped well in foil. Store for up to 1 month; add fresh avocado right before serving for the best texture.
Reheating
To reheat, unwrap and warm the sandwich in a 350°F oven for 10–12 minutes until heated through. Microwaving works in a pinch—just be sure to wrap in a damp paper towel to help keep the eggs moist.
FAQs
Can I use a different type Breakfast
Absolutely! While brioche is soft and rich, potato rolls, ciabatta, or hearty sourdough all make tasty alternatives for the Fairfax Breakfast Sandwich. Just choose something that holds fillings well.
Can I make the caramelized onions ahead of time?
Yes, caramelized onions can be made days in advance! Cool completely, store in an airtight container in the fridge, and they’ll stay delicious for up to 5 days—ready to transform any sandwich.
What’s the best way to get incredibly soft scrambled eggs?
Slow and steady wins the race: cook eggs over low to medium-low heat, stirring constantly with a soft spatula. Pull them from the heat just before they’re fully set so they stay soft and luscious.
Is there a vegan or dairy-free option?
Easily! Swap the butter for vegan margarine, use dairy-free cheese, and opt for a plant-based sriracha mayo. You can even use tofu scramble in place of eggs for a fully vegan Fairfax Breakfast Sandwich.
Can I add extra fillings to the Fairfax Breakfast Sandwich?
Of course! Feel free to add sautéed spinach, bacon, tomato slices, or even a handful of fresh arugula for extra flavor and texture. This sandwich is as versatile as your imagination.
