Instructions

  1. Step 1: Preheat the oven to 400°F. Place 2 skin-on salmon fillets on a baking sheet lined with parchment paper. Rub each fillet evenly with 2 tbsp Cajun seasoning and drizzle with 1 tbsp olive oil.
  2. Step 2: Bake the salmon for 12-15 minutes until the edges are slightly crispy and the flesh flakes easily with a fork.
  3. Step 3: While the salmon bakes, heat 2 tbsp unsalted butter in a large skillet over medium heat until melted and foaming.
  4. Step 4: Add 3 minced garlic cloves and sauté for 30 seconds until fragrant but not browned.
  5. Step 5: Add 1 lb trimmed asparagus spears, 1 tsp salt, and 1/2 tsp black pepper. Cook, stirring occasionally, for 5-7 minutes until asparagus is tender but still bright green.
  6. Step 6: Remove asparagus from heat, squeeze juice from 2 lemon wedges over the top, and toss gently.
  7. Step 7: Plate the salmon fillets alongside the garlic-butter asparagus and serve immediately.
