Instructions
- Step 1: Preheat oven to 425°F. On a large rimmed baking sheet, toss 1 large sweet potato cut into 1/2-inch wedges with 2 tbsp olive oil, 1/2 tsp salt, and 1/4 tsp black pepper. Spread in a single layer and roast for 15 minutes.
- Step 2: While sweet potatoes roast, pat dry 2 salmon fillets (6 oz each). Rub each fillet evenly with 2 tbsp Cajun seasoning mixed with 1 tbsp olive oil and sprinkle with remaining 1/2 tsp salt and 1/4 tsp black pepper.
- Step 3: After the sweet potatoes have roasted for 15 minutes, remove the sheet pan and create space on one side. Place the salmon fillets skin-side down on the open space.
- Step 4: Return the sheet pan to the oven and roast everything together for an additional 12-15 minutes, until salmon is opaque and flakes easily with a fork and sweet potatoes are tender.
- Step 5: Serve salmon and sweet potatoes with 4 lemon wedges for squeezing over the top.
