Pre-heat the broiler in your oven and line a sheet pan with foil.
Pat raw salmon filets dry with a paper towel.
Mix up mayonnaise, sriracha, garlic, salt and lemon juice in a small bowl. I like 2 good pinches of Kosher salt per 2 tablespoon of mayo.
Spread the mayo mixture on top fo the salmon.
Broil in the oven for 3-5 minutes and keep an eye on the salmon. The mayo will bubble. Then, shut the broiler off and set the oven to 400 degrees F.
Move the salmon to the middle oven rack. Let finish cooking for another 10-13 minutes in the oven.
Salmon is done when it flakes easily with a fork or is at least 145 degrees F when measured with an instant read thermometer.
