Make the caramelized onions:
The caramelized onions will take the longest, so get those started first.
In a large saucepan, melt the butter over medium heat. Add the onions and stir until they start to turn translucent, approx 1-2 minutes.
Reduce heat to low and simmer onions for 30-40 minutes, stirring occasionally so they don't stick.
If the onions do start to stick and/or burn, reduce heat lower and add a tablespoon or two of water, stirring to reabsorb.
Set onions aside.
Make the sriracha mayo:
In a small bowl, stir together the mayonnaise, sriracha, and lemon juice. Taste. Add another teaspoon of sriracha if you'd like more kick!
Make the scrambled eggs:
The last thing you want to do is make the scrambled eggs. They will be fast! Make sure all assembly ingredients are prepped before you start.
In a small pot or saucepan, melt the butter over low heat. Crack the eggs into the pot/pan and break up yolks with a wooden spoon.
Keep stirring the eggs over low heat, watching as the curds start to form. If the eggs start and cooking too quickly, remove the pan from the heat, stir, and then return to the heat once the curds are broken up again. The idea is you want to cook the eggs very slowly over low heat to form small, soft curds.
Once the eggs are set but still creamy-looking, remove from the heat. Stir in the chives, and get ready to assemble your sandwiches!
Turn your oven on to the broil setting (see note). Cut brioche buns in half and place the halves on a baking sheet. On two halves of the buns, arrange 2 slices of sharp cheddar cheese each. Place baking sheet in the oven and broil for a few minutes until the cheese melts. Remove from oven.
Transfer buns to plates to assemble. On the non-cheesy side, spread a generous amount of sriracha mayo. Add a large spoonful of scrambled eggs, then a serving of caramelized onions. Then place the bacon on top, if using.
Lastly, close the sandwich with the other half of the bun, and devour!
