Ingredients
- 2 pieces (6 oz each) salmon fillets
- 2 tbsp cajun seasoning
- 2 tbsp olive oil
- 3 tbsp unsalted butter
- 4, minced garlic cloves
- 1 tbsp, freshly squeezed lemon juice
- 1 tbsp, chopped fresh parsley
- 1 bunch (about 12 spears), trimmed asparagus spears
- 1 tsp salt
- 1/2 tsp black pepper
Instructions
- Step 1: Preheat oven to 400°F. Place 1 bunch of trimmed asparagus spears on a baking sheet and drizzle with 1 tbsp olive oil, 1/2 tsp salt, and 1/4 tsp black pepper. Toss to coat evenly and spread in a single layer.
- Step 2: Pat dry 2 salmon fillets (6 oz each) and rub evenly with 2 tbsp Cajun seasoning. Place the salmon fillets on the baking sheet next to the asparagus.
- Step 3: Bake in the preheated oven for 12-15 minutes until the salmon is opaque and flakes easily with a fork, and the asparagus is tender-crisp.
- Step 4: Meanwhile, melt 3 tbsp unsalted butter in a small saucepan over medium heat. Add 4 minced garlic cloves and sauté for 1-2 minutes until fragrant but not browned. Remove from heat and stir in 1 tbsp freshly squeezed lemon juice and 1 tbsp chopped fresh parsley.
- Step 5: Remove the baking sheet from the oven and spoon the garlic butter evenly over the salmon fillets and asparagus. Serve immediately for a flavorful and balanced meal.
