For sizzling, spiced, and perfectly charred salmon fajitas at home, all you need is a sheet pan, some pantry basics, and a smokin’ hot broiler. Blasting fish and veggies with the top down heat of a broiler is an easy way to develop the char you’d get from grilled salmon fajitas, but with the efficiency of sheet pan cooking.
Our recipe for sheet pan salmon fajitas is flavored with a layer of spiced mayo, which you can buy at the store (chipotle mayo is a great option!) or easily make at home by jazzing up mayonnaise with taco seasoning. Alternatively, you can mix together a dash of cayenne, chili powder, paprika, garlic powder, cumin, and coriander with mayo, to taste. This spiced mayo will add a punch of flavor to the salmon fillets, while keeping them tender and moist as they cook.
To accompany the salmon, you’ll broil a mix of bell peppers and onions, which sweeten up as they cook. They need a bit more time to cook than salmon fillets, so they’ll go under the broiler for a head start. And for serving, it’s nice to have some fresh ingredients to contrast with smoky, roasty flavors of the meal: pico de gallo, sour cream, lime, hot sauce, whatever you fancy with fajitas.
