Instructions

  1. Step 1: Season 4 salmon fillets with 1/2 tsp salt and 1/4 tsp black pepper evenly on both sides.
  2. Step 2: Heat 2 tbsp olive oil in a large nonstick skillet over medium-high heat until shimmering. Place salmon fillets skin-side down and cook for 5-6 minutes without moving until skin is crisp and golden.
  3. Step 3: Flip salmon and cook for an additional 3-4 minutes until the fish is just cooked through and flakes easily. Remove salmon from skillet and keep warm.
  4. Step 4: Reduce heat to medium and add 4 tbsp unsalted butter to the skillet. Once melted, stir in 2 minced garlic cloves and cook for 30 seconds until fragrant.
  5. Step 5: Add 1/4 cup fresh orange juice and 2 tbsp fresh lemon juice, simmer for 2 minutes until the sauce slightly thickens and coats the back of a spoon.
  6. Step 6: Meanwhile, in a separate pan, sauté 5 cups fresh baby spinach with 1/2 tsp salt and 1/4 tsp black pepper over medium heat for 2-3 minutes until wilted.
  7. Step 7: Serve the salmon fillets topped with the citrus butter sauce alongside the wilted spinach.
