Instructions

  1. Step 1: Preheat your oven to 425°F. Peel and dice 2 medium sweet potatoes into 1-inch cubes, then toss them with 2 tbsp extra virgin olive oil, 1/2 tsp sea salt, 1/4 tsp black pepper, and 1/2 tsp paprika. Spread evenly on a baking sheet and roast for 25-30 minutes until tender and golden, flipping halfway through.
  2. Step 2: While the potatoes roast, pat dry 2 salmon fillets (6 oz each), season both sides with 1/2 tsp sea salt and 1/4 tsp black pepper. Heat 1 tbsp olive oil in a skillet over medium-high heat until shimmering. Add salmon skin-side down and cook for 4-5 minutes until the edges are crispy, then flip and cook 2-3 more minutes until just opaque. Remove salmon and keep warm.
  3. Step 3: In the same skillet, add 1 tbsp olive oil and finely mince 4 garlic cloves. Sauté over medium heat for 30 seconds until fragrant but not browned. Add 5 cups baby spinach and 1/4 tsp sea salt, stirring constantly until spinach is wilted, about 2 minutes.
  4. Step 4: Plate the roasted sweet potatoes, place salmon fillets on top, and spoon the garlic spinach alongside. Finish with fresh juice from 2 lemon wedges to brighten the flavors before serving.
