Ingredients

• 2 (6-ounce) salmon fillets, skin on or off
• 1 bunch fresh asparagus, trimmed
• 2 tablespoons olive oil
• 1 lemon, half thinly sliced, half juiced
• 1 tablespoon chopped fresh dill
• 1 tablespoon chopped fresh parsley
• 1 teaspoon chopped fresh rosemary
• 2 cloves garlic, minced
• Salt, to taste
• Black pepper, freshly ground, to taste

Step-by-Step Instructions

1. Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper for easy cleanup. This step is crucial for preventing sticking and making the aftermath of cooking a breeze.
2. Prepare the asparagus. Wash the asparagus and snap off the woody ends. You can do this by holding the spear and bending it; it will naturally break at the point where the woody part begins. Alternatively, use a knife to trim 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 freshly ground black pepper, and toss to coat evenly. Spread them out in a single layer.
4. Prepare the salmon. Pat the salmon fillets dry with paper towels. This helps the skin crisp up if you’re leaving it on and ensures a better sear if you were pan-searing (though we’re roasting here, it’s still a good habit). Place the salmon fillets on the other side of the baking sheet, leaving a little space between them.
5. Make the herb marinade. In a small bowl, whisk together the remaining 1 tablespoon of olive oil, the juice of half a lemon, minced garlic, chopped fresh dill, chopped fresh parsley, and chopped fresh rosemary. Season this mixture with salt and pepper to your liking.
6. Season and marinate the salmon. Spoon the herb marinade evenly over the top of each salmon fillet. Gently spread it to cover the surface.
7. Add lemon slices. Arrange the thin lemon slices over the top of the salmon fillets. These will roast and become slightly caramelized, infusing the fish with even more lemon flavor.
8. Bake the dish. Place the baking sheet in the preheated oven. Roast for 15 to 20 minutes, or until the salmon is cooked through and flakes easily with a fork, and the asparagus is tender-crisp. The cooking time will depend on the thickness of your salmon fillets. Thinner fillets will cook faster.
9. Check for doneness. To check if the salmon is cooked, gently press the thickest part of the fillet with a fork. It should flake apart easily. The asparagus should be bright green and slightly tender. If it’s still too firm for your liking, you can return it to the oven for a few more minutes.
10. Serve. Carefully remove the baking sheet from the oven. Serve the Lemon Herb Roasted Salmon and Asparagus immediately. You can squeeze a little extra fresh lemon juice over everything just before serving for an extra burst of brightness.

Chef’s Secret Tip

For exceptionally flaky and moist salmon, don’t overcook it! The residual heat will continue to cook the fish after it’s out of the oven. Aim for an internal temperature of about 130-135°F (54-57°C) for medium-rare, or 140-145°F (60-63°C) for medium. A quick check with an instant-read thermometer is your best friend here.

Variations and Substitutions

This recipe is wonderfully adaptable. Don’t have dill? Use more parsley or cilantro. No rosemary? Thyme is a fantastic substitute. If you’re not a fan of asparagus, broccoli florets or green beans would work just as well. Toss them with the same seasonings and roast alongside the salmon. For a little heat, add a pinch of red pepper flakes to the herb marinade. If you want to make it a more complete meal, you can roast some baby potatoes or sweet potato cubes on the same baking sheet. Just make sure to cut them small enough so they cook in the same amount of time as the salmon and asparagus, or add them to the pan a little earlier. Another idea is to add cherry tomatoes to the pan; they become wonderfully sweet and jammy when roasted. You could also swap out the salmon for other types of fish like cod, halibut, or even trout. Adjust the cooking time slightly depending on the density of the fish.

Pro Tips for Perfect Roasting

* Don’t overcrowd the pan: Giving your ingredients space on the baking sheet allows them to roast rather than steam. If your baking sheet is too crowded, consider using two smaller pans. This ensures even cooking and caramelization.
* Even thickness for vegetables: When prepping vegetables like asparagus, try to ensure they are of a similar thickness. This will help them cook evenly. If you have very thick spears and very thin ones, you might want to group them separately or add the thinner ones a few minutes after the thicker ones.
* Pat your fish dry: As mentioned earlier, patting your salmon dry helps to achieve a better texture. It removes excess moisture, allowing the herbs and lemon to penetrate better and the surface to brown nicely.
* Use fresh herbs: While dried herbs can be used in a pinch, fresh herbs elevate this dish significantly. The vibrant flavors are key to its success. If you must use dried, use about one-third the amount of fresh.
* Adjust lemon to your taste: The amount of lemon juice and slices can be adjusted based on how much citrus flavor you prefer. You can even add a wedge of lemon to each plate for squeezing at the table.
* Parchment paper is your friend: I cannot stress this enough. Parchment paper makes cleanup so much easier. It also helps prevent sticking and promotes even cooking.

Frequently Asked Questions (FAQs)

Can I make this recipe ahead of time?

While the flavors are best when fresh, you can prep the marinade and trim the asparagus a few hours in advance. Store them separately in the refrigerator. It’s best to cook the salmon and asparagus just before serving for optimal texture and flavor.

What can I serve with Lemon Herb Roasted Salmon & Asparagus?

This dish is quite complete on its own, but it pairs wonderfully with a simple side of quinoa, rice pilaf, or a crusty baguette for soaking up any delicious pan juices. A light, crisp salad is also a great accompaniment.

How do I know if my salmon is cooked?

Salmon is cooked when it flakes easily with a fork at its thickest part. It should have a slightly opaque appearance. If you’re unsure, an instant-read thermometer inserted into the thickest part should read between 130-145°F (54-63°C), depending on your preferred level of doneness.

Can I use frozen salmon?

Yes, you can. Thaw the salmon completely in the refrigerator before cooking. Pat it thoroughly dry before proceeding with the recipe.

Is skin-on or skin-off salmon better for this recipe?

Both work well. Skin-on salmon can help keep the fillet from falling apart during cooking and can become wonderfully crispy if cooked correctly. Skin-off salmon is also delicious and might be preferred by some.

How long will leftovers last?

Leftovers can be stored in an airtight container in the refrigerator for up to 2-3 days. Reheat gently to avoid drying out the fish.
