Instructions

  1. Step 1: Preheat oven to 400°F. Place 4 salmon fillets skin-side down on a parchment-lined baking sheet. Brush each fillet with 1 tbsp olive oil and season evenly with 1/2 tsp sea salt and 1/4 tsp black pepper. Roast for 12-15 minutes until salmon flakes easily with a fork.
  2. Step 2: While salmon roasts, prepare avocado-cilantro sauce by blending 1 ripe avocado, 1/3 cup fresh cilantro leaves, 2 tbsp fresh lime juice, 1 minced garlic clove, 2 tbsp olive oil, 1/2 tsp sea salt, 1/4 tsp black pepper, and 1/4 tsp red pepper flakes (if using) in a food processor until smooth and creamy.
  3. Step 3: Remove salmon from oven and spoon generous dollops of the avocado-cilantro sauce over each fillet. Serve immediately with extra lime wedges if desired.
