Step 1

Preheat the oven to 400°F. Line a large, rimmed baking sheet with foil, and lightly brush the foil with oil.

Step 2

In a shallow bowl, mix together brown sugar, paprika, chili powder, salt, garlic, cayenne pepper, and lime zest together.

Step 3

Pat dry the salmon fillets and then pat the seasoning mixture onto the flesh side of each piece of salmon. Place the salmon, skin side down, on the prepared baking sheet.

Step 4

Insert an oven-safe digital thermometer into the end of the thickest part of one of the salmon fillets, ensuring that the probe is not angled downward nor touching the pan. Place the pan in the oven and cook until the salmon reaches 140°F, about 15 to 20 minutes, depending on the thickness of the salmon.

Step 5

Once the salmon reaches 140 degrees, remove the pan from the oven, loosely cover with foil, and allow to rest until the temperature increases to 145°F.

Step 6

Drizzle with fresh lime juice and then serve immediately.
