Ingredients List

For the salmon:

• 4 salmon fillets (6 oz each), preferably wild-caught
• 4 tablespoons unsalted butter, softened
• 2 lemons (1 juiced, 1 sliced)
• 4 cloves garlic, minced
• 1 tablespoon fresh dill, chopped (or 1 teaspoon dried)
• 1 teaspoon sea salt
• 1/2 teaspoon freshly ground black pepper

For the asparagus:

• 1 pound fresh asparagus, woody ends trimmed
• 2 tablespoons olive oil
• 1/2 teaspoon garlic powder
• Salt and pepper to taste

Substitution options: Use ghee instead of butter for a dairy-sensitive option, or swap asparagus with green beans or broccoli if preferred.

• Cooking time: 20 minutes

Step-by-Step Instructions

Step 1: Preheat and Prep

Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper or aluminum foil for easy cleanup. This simple step saves an average of 5 minutes on post-cooking cleanup.

Step 2: Make the Lemon Butter Mixture

In a small bowl, combine the softened butter, juice from one lemon, minced garlic, chopped dill, salt, and pepper. Mix until well incorporated. This fragrant mixture is the secret weapon of this easy lemon butter salmon recipe.

Step 3: Prepare the Salmon

Place the salmon fillets skin-side down on one side of the prepared baking sheet. Using a silicone brush or the back of a spoon, generously coat each fillet with the lemon butter mixture. Pro tip: Score the top of the salmon slightly with a knife before applying the butter to allow the flavors to penetrate deeper.

Step 4: Arrange the Asparagus

On the other side of the baking sheet, arrange the asparagus in a single layer. Drizzle with olive oil and season with garlic powder, salt, and pepper. Toss gently to coat evenly. Keeping the vegetables separate from the salmon ensures perfect cooking for both components.

Step 5: Add Lemon Slices

Place lemon slices on top of the salmon fillets and scatter a few among the asparagus. This not only adds a beautiful presentation but infuses everything with bright citrus flavor as it roasts.

Step 6: Bake to Perfection

Place the sheet pan in the preheated oven and bake for 15-20 minutes, or until the salmon flakes easily with a fork and the asparagus is tender-crisp. The internal temperature of the salmon should reach 145°F (63°C) for food safety.

Step 7: Serve and Enjoy

Remove from the oven and let rest for 2 minutes. Transfer to plates and drizzle any remaining pan juices over the salmon and asparagus for an extra flavor boost.

Common Mistakes to Avoid

1. Overcooking the salmon: Studies show that salmon loses up to 15% of its moisture when overcooked. Watch carefully after the 15-minute mark.
2. Using asparagus that’s too thin: Choose medium-thickness asparagus stalks that can withstand the same cooking time as the salmon.
3. Not patting the salmon dry: Excess moisture prevents proper browning. Always pat fillets dry with paper towels before seasoning.
4. Forgetting to remove woody asparagus ends: The bottom inch of asparagus contains tough fibers that can ruin the eating experience.
5. Using cold butter: Softened butter blends more easily with other ingredients, creating a more flavorful coating.

Storing Tips for the Recipe

This simple baked salmon recipe creates excellent leftovers that maintain quality when stored properly:

• Refrigerate leftovers in an airtight container for up to 2 days
• For best texture, reheat salmon gently in a 275°F oven for 10-15 minutes
• Asparagus can be enjoyed cold in salads or reheated separately in a skillet
• Freeze uncooked salmon with the butter mixture for up to 1 month for an even quicker future meal
• Prep the lemon butter mixture up to 3 days ahead and store refrigerated for convenience
