Ingredients

• Four 6-ounce salmon fillets, skin on or off (your preference)
• 1 pound fresh asparagus, trimmed
• 2 tablespoons olive oil, plus extra for drizzling
• 1 tablespoon fresh lemon juice, plus wedges for serving
• 1 teaspoon dried oregano
• 1 teaspoon dried thyme
• ½ teaspoon garlic powder
• ¼ teaspoon salt, or to taste
• ⅛ teaspoon black pepper, or to taste
• Optional: Fresh parsley, chopped, for garnish

Instructions

1. Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper for easy cleanup.
2. Prepare the asparagus. Wash the asparagus spears and snap off the tough, woody ends. You can do this by holding a spear in each hand and bending it; it will naturally break at the right spot. Place the trimmed asparagus in a medium bowl.
3. Season the asparagus. Drizzle the asparagus with 1 tablespoon of olive oil, sprinkle with ¼ teaspoon of salt and ⅛ teaspoon of black pepper. Toss gently to coat each spear evenly. Spread the seasoned asparagus in a single layer on one side of the prepared baking sheet.
4. Prepare the salmon. Pat the salmon fillets dry with paper towels. This step is crucial for achieving a nice, seared exterior. Place the salmon fillets on the other side of the baking sheet, leaving a little space between each fillet.
5. Make the lemon herb mixture. In a small bowl, whisk together the remaining 1 tablespoon of olive oil, 1 tablespoon of fresh lemon juice, dried oregano, dried thyme, garlic powder, the remaining ¼ teaspoon of salt, and the remaining ⅛ teaspoon of black pepper.
6. Season the salmon. Spoon the lemon herb mixture evenly over the top of each salmon fillet, ensuring they are well-coated.
7. Roast the salmon and asparagus. 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. The asparagus should be crisp-tender and slightly browned. Cooking time will vary depending on the thickness of your salmon fillets. Thicker fillets will require more time.
8. Rest and serve. Once cooked, remove the baking sheet from the oven. Let the salmon rest for a couple of minutes before serving.
9. Garnish and enjoy. Serve the lemon herb roasted salmon alongside the roasted asparagus. Garnish with freshly chopped parsley, if desired, and serve with lemon wedges for an extra burst of freshness.

Pro Tips

This dish is wonderfully forgiving, but a few extra touches can elevate it from great to absolutely unforgettable. Here are my seasoned insights to ensure your Lemon Herb Roasted Salmon with Asparagus is a roaring success every time.

Firstly, the quality of your salmon truly matters. Opt for fresh, high-quality salmon fillets. Look for vibrant color and a firm texture. If you’re buying frozen, ensure it’s been thawed properly in the refrigerator overnight. For skin-on fillets, a crispier skin adds a delightful textural contrast to the tender flesh. To achieve this, make sure the skin side is thoroughly patted dry before seasoning.

When it comes to asparagus, freshness is key. Seek out spears that are firm, bright green, and have tight buds at the tips. If the tips are open or floppy, they are past their prime. Trimming the woody ends is essential for palatability. Don’t be shy about snapping them off; they will break naturally at the tender point. If you’re unsure, you can also use a knife to trim about an inch off the bottom of each spear.

The herb combination is a classic for a reason, but feel free to experiment! Rosemary and dill are wonderful additions or substitutions for oregano and thyme. A pinch of red pepper flakes can add a gentle warmth that complements the lemon beautifully. For an even more robust garlic flavor, you could mince 1-2 cloves of fresh garlic and add them to the olive oil and lemon juice mixture, but be mindful that minced garlic can burn more easily than garlic powder, so keep an eye on it.

Don’t overcrowd the baking sheet. Giving the salmon and asparagus ample space allows them to roast rather than steam. If your baking sheet is too crowded, you might need to use two sheets or cook in batches. This ensures that everything develops a lovely roasted char and prevents sogginess.

For perfectly cooked salmon, aim for an internal temperature of 125-130°F (52-54°C) for medium-rare, or 135-140°F (57-60°C) for medium. The exact cooking time will depend on the thickness of your fillets and your oven’s calibration. It’s always better to err on the side of slightly undercooked, as the salmon will continue to cook slightly as it rests. A good visual cue is when the salmon turns opaque and the flakes begin to separate easily.

The lemon is the star of the show, providing that bright, zesty counterpoint to the rich salmon. Don’t be tempted to skip the lemon wedges for serving. A final squeeze of fresh lemon juice right before eating can brighten up all the flavors.

If you have leftover salmon and asparagus, they make for a fantastic cold salad the next day. Flake the salmon and chop the asparagus, then toss with a light vinaigrette and some mixed greens. It’s a refreshing and healthy lunch option.

FAQs

Q1: Can I use frozen salmon for this recipe?

A1: Yes, you can use frozen salmon. It’s best to thaw it completely in the refrigerator overnight before using. Ensure it’s well-drained and patted dry before proceeding with the recipe.

Q2: What if I don’t have asparagus? What other vegetables can I roast alongside the salmon?

A2: Absolutely! This method works beautifully with many other vegetables. Broccoli florets, green beans, Brussels sprouts (halved), bell pepper strips, or even cherry tomatoes would be excellent substitutes or additions. Adjust roasting time as needed for denser vegetables.

Q3: How do I know when the salmon is cooked through?

A3: The salmon is cooked when it flakes easily with a fork. Visually, it will turn from translucent to opaque. For a more precise measurement, use an instant-read thermometer. The internal temperature should be around 125-130°F (52-54°C) for medium-rare to 135-140°F (57-60°C) for medium.

Q4: Can I make this dish ahead of time?

A4: While it’s best enjoyed fresh, you can prep the vegetables and the lemon herb mixture ahead of time. Store them separately in the refrigerator. You can also season the salmon and cover it, but it’s ideal to roast it just before serving for the best texture and flavor.

Q5: Is it okay to use fresh herbs instead of dried?

A5: Yes, fresh herbs are a wonderful alternative! If using fresh oregano and thyme, you’ll want to use a larger quantity, about 1 tablespoon of each, finely chopped. Add them to the lemon herb mixture along with the olive oil.

Q6: My salmon is sticking to the parchment paper. What went wrong?

A6: Ensure your parchment paper is fresh and of good quality. Sometimes, if the oven is too hot or the parchment isn’t quite doing its job, a little bit of sticking can occur. A very light greasing of the parchment paper itself can sometimes help, but generally, good quality parchment should prevent this.

Q7: What kind of salmon is best for roasting?

A7: Salmon with a good fat content, like Atlantic salmon or King salmon, is excellent for roasting as it stays moist. However, Sockeye salmon is also a good choice, though it can be leaner and may require slightly less cooking time to avoid drying out.

Chef’s Secret Tip: The Zest is Best!

Before you squeeze that lemon juice, take a microplane or fine grater to the zest of the lemon. Add this finely grated zest to your olive oil and herb mixture. It infuses an even more intense, pure lemon flavor throughout the dish without adding extra liquid, and the tiny flecks of zest look beautiful on the finished salmon.
