Ingredients

• 1.5 pounds skin-on salmon fillets (about 4-6 fillets)
• 1 pound baby Yukon Gold potatoes, quartered
• 1 pound fresh asparagus, trimmed
• 1/4 cup extra virgin olive oil
• 2 tablespoons fresh lemon juice
• 4 cloves garlic, minced
• 1 teaspoon dried rosemary
• 1 teaspoon dried thyme
• 1/2 teaspoon dried oregano (optional)
• 1/2 teaspoon sea salt, plus more for potatoes and asparagus
• 1/4 teaspoon black pepper, plus more for potatoes and asparagus
• Lemon wedges, for serving
• Fresh parsley, chopped, for garnish (optional)

Instructions

1. Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper for easy cleanup. If you don’t have parchment paper, lightly grease the baking sheet with olive oil.
2. In a large bowl, toss the quartered baby potatoes with 1 tablespoon of olive oil, 1/4 teaspoon of salt, and 1/4 teaspoon of black pepper. Spread the potatoes in a single layer on one half of the prepared baking sheet.
3. Roast the potatoes for 15 minutes. This initial roasting helps them to start cooking and soften before adding the other ingredients, ensuring they are tender by the time the salmon is cooked.
4. While the potatoes are roasting, prepare the salmon and asparagus marinade. In a small bowl, whisk together the remaining 3 tablespoons of olive oil, fresh lemon juice, minced garlic, dried rosemary, dried thyme, dried oregano (if using), 1/2 teaspoon of salt, and 1/4 teaspoon of black pepper.
5. Pat the salmon fillets dry with paper towels. This helps the marinade adhere better and promotes crispier skin.
6. Trim the woody ends off the asparagus. Toss the asparagus with 1 teaspoon of olive oil, a pinch of salt, and a pinch of black pepper directly on the baking sheet once you remove it for the next step.
7. After the potatoes have roasted for 15 minutes, carefully remove the baking sheet from the oven.
8. Arrange the salmon fillets skin-side down on the empty half of the baking sheet, alongside the partially roasted potatoes.
9. Pour the lemon herb marinade evenly over the salmon fillets, ensuring they are well coated.
10. Scatter the seasoned asparagus spears around the salmon and potatoes on the baking sheet. Try to keep everything in a single layer for even cooking.
11. Return the baking sheet to the oven and roast for another 15-20 minutes, or until the salmon is cooked through and flakes easily with a fork, the asparagus is tender-crisp, and the potatoes are golden brown and fully cooked. The exact cooking time will depend on the thickness of your salmon fillets and your oven.
12. Once cooked, carefully remove the baking sheet from the oven.
13. Serve the lemon herb salmon, asparagus, and potatoes immediately. Garnish with fresh chopped parsley and serve with lemon wedges for squeezing over the top.

Chef’s Secret Tip: For extra crispy roasted potatoes, consider par-boiling them for about 5-7 minutes before tossing them with olive oil and seasoning. Drain them well, rough up the edges slightly in the colander, and then proceed with roasting. This creates more surface area for browning, resulting in a superior texture.

Pro Tips for Sheet Pan Success

Sheet pan dinners are all about efficiency and flavor, but a few tweaks can elevate them from good to extraordinary. Here are some of my favorite tips to ensure your Lemon Herb Salmon with Asparagus & Potatoes turns out perfectly every time.

Ingredient Prep Matters

When it comes to vegetables on a sheet pan, uniformity is key. For the potatoes, cutting them into similar-sized pieces ensures they cook evenly. If you have very thick asparagus spears, consider snapping them in half or cutting them into 2-inch pieces to match the cooking time of the salmon and potatoes. For thinner spears, leaving them whole is usually fine. Remember to trim off the woody ends of the asparagus – they’re not pleasant to eat and can be fibrous.

Don’t Overcrowd the Pan

This is probably the most crucial tip for any sheet pan meal. If you overcrowd your baking sheet, your ingredients will steam instead of roast. Steaming leads to soggy vegetables and poorly cooked protein. If your baking sheet looks too full, don’t hesitate to use two sheets. The goal is to allow hot air to circulate around each piece of food, creating that desirable browning and crispiness.

Marinade Magic

The marinade is where the flavor really comes alive. For the salmon, ensure it’s patted dry before marinating. This allows the marinade to adhere better and prevents the skin from becoming too wet, which can hinder crisping. Feel free to experiment with your herbs! While rosemary and thyme are classic pairings with salmon, don’t be afraid to add dill, parsley, or even a touch of smoked paprika for a different flavor profile. If you have fresh herbs on hand, use them! Double the amount of fresh herbs compared to dried. Chop them finely and add them to the marinade.

Oven Temperature and Time

The 400°F (200°C) temperature is ideal for this recipe, allowing the vegetables to roast and caramelize while the salmon cooks through quickly. However, oven thermostats can vary, so it’s always a good idea to know your oven. If you find your oven runs hot, you might need to reduce the temperature slightly or shorten the cooking time. The salmon is done when it’s opaque and flakes easily with a fork. The asparagus should be tender but still have a slight bite to it (al dente). The potatoes should be fork-tender and golden brown on the edges.

Post-Roast Flavor Boost

A squeeze of fresh lemon juice right before serving can really brighten up all the flavors. You can also add a sprinkle of flaky sea salt over the salmon and vegetables for an extra pop of texture and flavor. A drizzle of good quality olive oil at the end can also add a lovely richness. Don’t underestimate the power of fresh herbs as a garnish, either. Finely chopped parsley or dill adds a burst of freshness and visual appeal.

Make it Your Own

This recipe is a fantastic base for customization. Don’t like asparagus? Swap it out for broccoli florets, green beans, or even Brussels sprouts. Just adjust the cooking time as needed – denser vegetables like Brussels sprouts might need a head start similar to the potatoes. You can also add cherry tomatoes to the pan during the last 10-15 minutes of cooking for a burst of sweetness. For a spicier kick, add a pinch of red pepper flakes to the marinade or sprinkle them over the vegetables.

FAQs

Can I use a different type of fish?

Yes, absolutely! This recipe works beautifully with other types of fish that have a similar cooking time, such as cod, halibut, or even a firm white fish like sea bass. Adjust the cooking time based on the thickness of the fish fillets. Remember to pat them dry before marinating.

What if I don’t have baby potatoes?

You can use regular potatoes like Russets or Yukon Golds, but you’ll need to peel them and cut them into smaller, more uniform cubes (about 1-inch). It might also take them a bit longer to roast, so you may want to give them a 20-25 minute head start on the baking sheet before adding the salmon and asparagus. Ensure they are fork-tender before serving.

Can I make this recipe ahead of time?

You can prepare the marinade ahead of time and store it in an airtight container in the refrigerator for up to 2 days. You can also chop the vegetables and potatoes ahead of time and store them in separate containers in the refrigerator. However, it’s best to assemble and roast the dish just before serving for the freshest results. The salmon is best enjoyed right after cooking.

How do I know when the salmon is cooked?

The salmon is cooked when it is opaque throughout and flakes easily into large pieces with a fork. You can gently press on the thickest part of the fillet; if it flakes apart readily, it’s done. Overcooked salmon can be dry, so it’s better to err on the side of slightly undercooked and let it rest for a minute or two on the pan.

Can I use frozen asparagus?

While fresh asparagus is recommended for the best texture and flavor, you can use frozen asparagus in a pinch. Ensure you thaw it completely and pat it very dry with paper towels before adding it to the baking sheet. Frozen vegetables tend to release more moisture, which can affect the roasting process, so be mindful of that.
