Stovetop Blackened Salmon Recipe
Today, I’m sharing a recipe that was shared with me by a restaurant chef. Blackened salmon is something you might see on a restaurant menu and think there’s no way you can make it at home. But it’s actually really easy.
In this recipe, herbs and spices come together with a bit of brown sugar and maple syrup to create the perfect combination of savory and sweet.
What is Blackened Salmon?
Blackened salmon is a Cajun-inspired seafood preparation that involves coating the salmon in a blend of spices and then searing it in a hot skillet. This creates a delectable crust on the outside, and also locks in the salmon’s juices, keeping it nice and moist.
