Instructions

  1. Step 1: Pat dry 4 salmon fillets (6 oz each) and season both sides with 1/2 tsp sea salt and 1/4 tsp black pepper. Heat 2 tbsp olive oil in a large skillet over medium-high heat.
  2. Step 2: Place salmon skin-side down in the skillet and cook for 5-6 minutes without moving, until the skin is crisp and the salmon is cooked halfway through. Flip and cook for an additional 2-3 minutes until the salmon reaches an internal temperature of 125°F for medium.
  3. Step 3: Remove salmon from skillet and set aside. In the same skillet, add 1 tbsp olive oil and 3 minced garlic cloves. Sauté over medium heat for 30 seconds until fragrant.
  4. Step 4: Add 8 cups fresh spinach, 1/2 tsp sea salt, and 1/4 tsp black pepper to the skillet. Toss gently and cook for 2-3 minutes until the spinach wilts but remains bright green.
  5. Step 5: Remove from heat, drizzle with juice of 1 lemon, and sprinkle 1 tbsp lemon zest over the spinach and salmon. Serve immediately.
