Instructions

  1. Step 1: Pat dry 4 salmon fillets (6 oz each) and season both sides with 1 tsp sea salt and 1/2 tsp black pepper.
  2. Step 2: Heat 2 tbsp extra virgin olive oil in a large non-stick skillet over medium-high heat until shimmering, about 2 minutes.
  3. Step 3: Add salmon fillets skin-side down along with 2 fresh rosemary sprigs and sear for 5 minutes without moving, until edges are crispy and skin releases easily.
  4. Step 4: Flip salmon and cook for an additional 3 minutes until the thickest part is opaque and flakes easily.
  5. Step 5: Remove salmon and keep warm; reduce heat to medium and add 1 tbsp olive oil and 4 minced garlic cloves to the skillet.
  6. Step 6: Sauté garlic for 30 seconds until fragrant, then add 8 cups baby spinach and stir continuously for 2-3 minutes until wilted and tender.
  7. Step 7: Season spinach with a pinch of salt and remove rosemary sprigs.
  8. Step 8: Serve salmon over garlic-rosemary spinach with lemon wedges on the side for squeezing.
