Instructions

  1. Step 1: Preheat oven to 425°F. Toss 2 medium peeled and cubed sweet potatoes with 2 tbsp olive oil, 1 tsp sea salt, and 1 tsp paprika. Spread on a baking sheet and roast for 25-30 minutes, stirring halfway until tender and golden.
  2. Step 2: While sweet potatoes roast, heat 1 tbsp olive oil in a large skillet over medium heat. Add 4 minced garlic cloves and sauté for 30 seconds until fragrant, then add 8 cups fresh spinach and cook, stirring, until wilted, about 3-4 minutes. Season with 1/2 tsp sea salt and remove from heat.
  3. Step 3: Pat 4 salmon fillets dry and season both sides with 1 tsp sea salt and 1/2 tsp black pepper. Heat 1 tbsp olive oil in a separate skillet over medium-high heat. Add salmon fillets skin side down and cook for 4-5 minutes until edges are crispy, then flip and cook another 3-4 minutes until cooked through.
  4. Step 4: Remove salmon from heat and drizzle 2 tbsp fresh lemon juice over the fillets. Plate the sautéed spinach, top with roasted sweet potatoes, and place salmon fillets on top to serve.
