Instructions

  1. Step 1: Pat dry 4 salmon fillets (6 oz each) and season both sides with 1 tsp salt and 1/2 tsp black pepper. Heat 2 tbsp olive oil in a large nonstick skillet over medium-high heat until shimmering.
  2. Step 2: Place salmon fillets skin-side down in the skillet and cook for 4-5 minutes without moving until skin is crispy. Flip and cook for an additional 3-4 minutes until salmon is cooked through and flakes easily.
  3. Step 3: Remove salmon from skillet and set aside. Lower heat to medium and add 3 tbsp unsalted butter and 4 minced garlic cloves to the same skillet. Sauté for 1-2 minutes until fragrant but not browned.
  4. Step 4: Stir in 2 tbsp fresh lemon juice and 1/4 tsp red pepper flakes if using. Pour lemon-butter sauce over the salmon. Sprinkle with 2 tbsp chopped fresh parsley.
  5. Step 5: In a separate pan, heat 1 tbsp olive oil over medium heat. Add 8 cups fresh baby spinach and sauté for 2-3 minutes until wilted. Season with a pinch of salt and serve alongside salmon.
