Instructions

  1. Step 1: Pat dry 4 salmon fillets and season both sides with 1/2 tsp salt and 1/4 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 and cook for 5-6 minutes without moving until skin is crisp and salmon is cooked halfway through.
  3. Step 3: Flip salmon and cook for an additional 2-3 minutes until just cooked through. Remove salmon from skillet and set aside.
  4. Step 4: Reduce heat to medium, add remaining 1 tbsp olive oil and 4 minced garlic cloves to the skillet. Sauté for 1 minute until fragrant.
  5. Step 5: Add 6 cups fresh baby spinach, 1/2 tsp salt and 1/4 tsp black pepper. Cook, stirring frequently, until spinach is wilted, about 3 minutes.
  6. Step 6: Stir in 2 tbsp fresh lemon juice and 1 tsp lemon zest, cooking for 30 seconds until sauce coats spinach.
  7. Step 7: Return salmon to skillet nestling atop the spinach. Sprinkle 2 tbsp chopped fresh parsley before serving.
