Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F (220°C). Peel and cut 2 medium sweet potatoes into 1-inch cubes. Toss with 2 tbsp olive oil, 1/2 tsp salt, and 1/2 tsp black pepper, then spread evenly on a baking sheet.
  2. Step 2: Roast sweet potatoes in the oven for 20 minutes until edges are caramelized and tender.
  3. Step 3: While sweet potatoes roast, pat dry 2 salmon fillets (5 oz each). In a small bowl, mix 2 tsp Cajun seasoning, 1 tsp garlic powder, 1 tsp paprika, 1/2 tsp salt, and 1/4 tsp black pepper.
  4. Step 4: Rub the spice mixture evenly over both salmon fillets.
  5. Step 5: After sweet potatoes have roasted 20 minutes, push them to one side of the baking sheet and place salmon fillets skin-side down on the other side. Drizzle 1 tbsp olive oil over salmon.
  6. Step 6: Return to oven and bake everything for 12-15 minutes until salmon is opaque and flakes easily with a fork.
  7. Step 7: Sprinkle 2 tbsp chopped fresh parsley over the salmon and sweet potatoes before serving.
