Instructions
- Step 1: Preheat oven to 425°F. Toss 2 medium peeled sweet potato wedges with 2 tbsp olive oil, 1/2 tsp salt, and 1/4 tsp black pepper on a large sheet pan. Roast for 10 minutes.
- Step 2: Remove pan from oven, arrange 4 (6 oz) salmon fillets skin-side down on top of sweet potatoes. Drizzle with remaining 1 tbsp olive oil, then top with 4 minced garlic cloves, 1 tsp dried rosemary, and 1/2 tsp salt.
- Step 3: Scatter 1 lemon, thinly sliced, over salmon and sweet potatoes. Roast for 12-15 minutes until salmon is opaque and flakes easily with a fork.
- Step 4: Check for doneness by gently pressing the thickest part of salmon — it should feel firm but yield slightly. Transfer to plates immediately to prevent overcooking.
