Ingredients

• 4 (6-ounce) salmon fillets, skin on or off
• 1 pound fresh asparagus, trimmed
• 2 tablespoons olive oil
• 1 lemon, thinly sliced, plus more for serving
• 2 cloves garlic, minced
• 1 teaspoon dried dill
• 1 teaspoon dried parsley
• 1/2 teaspoon dried thyme
• Salt, to taste
• Black pepper, to taste

Instructions

1. Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper or aluminum foil for easy cleanup. This step is crucial to prevent sticking and make the post-cooking cleanup a breeze.
2. Prepare the asparagus. Wash the asparagus spears and snap off the woody ends. You can do this by holding a spear in your hands and bending it; it will naturally break at the point where the tough part meets the tender part. Alternatively, you can use a knife to cut off the bottom inch or so. Place the trimmed asparagus on one side of the prepared baking sheet.
3. Season the asparagus. Drizzle the asparagus with 1 tablespoon of olive oil. Season generously with salt and black pepper. Toss the asparagus gently to ensure all the spears are coated evenly. Spread them out in a single layer so they roast rather than steam.
4. Prepare the salmon. Pat the salmon fillets dry with paper towels. This helps create a better sear and allows the seasonings to adhere properly. Place the salmon fillets on the other side of the baking sheet, leaving some space between each fillet and the asparagus.
5. Make the lemon herb mixture. In a small bowl, combine the remaining 1 tablespoon of olive oil, minced garlic, dried dill, dried parsley, and dried thyme. Stir well to combine these aromatic elements.
6. Season the salmon. Spoon the lemon herb mixture evenly over the top of each salmon fillet. Make sure to get a good coating. Season the salmon with salt and black pepper to your preference. Don’t be shy with the salt; it will enhance the natural flavors of the fish and the herbs.
7. Add lemon slices. Arrange the thin lemon slices over and around the salmon fillets. The lemon will bake, releasing its juice and infusing the fish with a wonderfully bright, citrusy flavor. The lemon slices also add a beautiful visual appeal to the finished dish.
8. Roast the dish. Place the baking sheet in the preheated oven. Roast for 20-25 minutes, or until the salmon is cooked through and flakes easily with a fork, and the asparagus is tender-crisp. The cooking time will vary depending on the thickness of your salmon fillets. It’s always better to slightly undercook salmon than to overcook it, as it can become dry quickly.
9. Rest and serve. Once cooked, carefully remove the baking sheet from the oven. Let the salmon and asparagus rest for a minute or two before serving. This allows the juices to redistribute, ensuring a more moist and flavorful final product. Serve immediately.

Chef’s Secret Tip

For an extra layer of flavor and a beautiful presentation, finely zest half of one of the lemons before slicing the rest for the top of the salmon. Add this lemon zest to the herb and oil mixture. The zest contains the essential oils of the lemon, providing a more intense and complex citrus aroma and taste than the juice alone.

Pro Tips for Perfect Roasted Salmon

• Don’t Overcrowd the Pan: Ensure there’s enough space between your salmon fillets and asparagus on the baking sheet. Overcrowding can lead to steaming instead of roasting, resulting in a less desirable texture and flavor. If your baking sheet is too small, consider using two.
• Quality of Salmon Matters: Opt for fresh, high-quality salmon. Wild-caught salmon generally has a richer flavor and firmer texture than farmed salmon, but either will work well for this recipe. Look for fillets that are bright pink or orange in color and have a fresh, ocean-like scent.
• Adjust Seasonings to Your Taste: The herbs listed are a classic combination, but feel free to experiment. Fresh rosemary, chives, or even a pinch of red pepper flakes can add a wonderful twist. Similarly, adjust the salt and pepper to suit your personal preferences.
• Watch for Doneness: Salmon is best when it’s just cooked through and still moist. You can check for doneness by gently pressing the thickest part of the fillet with a fork. It should flake easily. If you’re unsure, use an instant-read thermometer; it should register around 135-140°F (57-60°C) for medium-rare to medium, or 145°F (63°C) for well-done.
• Vary Your Vegetables: While asparagus is a perfect partner for salmon, you can swap it out for other quick-roasting vegetables. Broccoli florets, green beans, bell pepper strips, or cherry tomatoes also work beautifully and can be added to the baking sheet at the same time as the asparagus.
• Skin-On vs. Skin-Off: Salmon skin can become delightfully crispy when roasted, adding a nice textural contrast. If you prefer to eat the skin, make sure to pat it dry thoroughly before seasoning. If you’re not a fan of salmon skin, you can easily remove it before cooking or ask your fishmonger to do it for you.
• Lemon Preparation is Key: Thinly slicing the lemon ensures that it releases its juices and flavors evenly during the roasting process without burning. Avoid using too many slices, as it can make the dish too sour.

Frequently Asked Questions (FAQs)

Can I use frozen salmon for this recipe?

Yes, you can use frozen salmon. Thaw it completely in the refrigerator overnight before cooking. Ensure it’s fully thawed and patted dry to achieve the best results. Do not attempt to cook salmon directly from frozen, as it will cook unevenly and likely result in a dry texture.

What can I serve with this lemon herb roasted salmon?

This dish is a complete meal on its own, but it also pairs wonderfully with a variety of sides. Consider serving it with quinoa, brown rice, or a simple side salad for added texture and nutrients. Roasted potatoes or sweet potato wedges are also excellent accompaniments. A dollop of plain Greek yogurt or a light aioli can also elevate the dish.

How can I make this recipe dairy-free?

This recipe is naturally dairy-free. No modifications are needed.

Can I make this recipe gluten-free?

Yes, this recipe is naturally gluten-free. All ingredients are typically gluten-free.

What if I don’t have fresh asparagus?

If fresh asparagus is out of season or unavailable, you can substitute it with other quick-roasting vegetables like broccoli, green beans, or Brussels sprouts. Adjust the cooking time as needed, as some vegetables may require slightly longer or shorter roasting times than asparagus.

How long does this salmon dish last in the refrigerator?

Leftovers can be stored in an airtight container in the refrigerator for up to 2-3 days. Reheat gently in a low oven or microwave to avoid overcooking.

Can I marinate the salmon?

While this recipe is designed for quick preparation, you could marinate the salmon for a short period (15-30 minutes) in a similar lemon-herb mixture before roasting for an even more intense flavor. However, be cautious with prolonged marinating of fish, as the acid in the lemon can “cook” the fish, altering its texture.

Why is my salmon dry?

The most common reason for dry salmon is overcooking. Salmon cooks very quickly, and even a few extra minutes can make a difference. It’s always best to err on the side of caution and check for doneness frequently, especially towards the end of the cooking time. Using a meat thermometer is the most reliable way to ensure perfectly cooked salmon.
