Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. In a large bowl, toss 2 medium peeled and cubed sweet potatoes with 2 tbsp olive oil, 1 tsp ground cumin, 3/4 tsp salt, and 1/4 tsp black pepper until evenly coated.
  2. Step 2: Spread sweet potatoes on one side of a large rimmed baking sheet in a single layer. Roast for 15 minutes.
  3. Step 3: Meanwhile, in the same bowl, toss 12 oz trimmed green beans with 1 tbsp olive oil, 1/2 tsp salt, and 1/4 tsp black pepper.
  4. Step 4: After 15 minutes, remove the baking sheet from the oven and stir sweet potatoes. Push them to one side and arrange 4 salmon fillets on the other side. Brush each salmon fillet generously with 3 tbsp harissa paste.
  5. Step 5: Scatter the green beans around the salmon and sweet potatoes, drizzle with remaining 1 tbsp olive oil.
  6. Step 6: Return the sheet pan to the oven and roast everything for an additional 12 minutes until salmon is opaque and flakes easily, sweet potatoes are tender, and green beans are crisp-tender.
  7. Step 7: Serve salmon with roasted vegetables and lemon wedges for squeezing over the top.
