Easy Lemon Herb Salmon & Asparagus – 30-Minute One-Pan

I remember the first time I made this dish. It was a rainy Tuesday, and I had just returned from a trip to the Greek islands, where the lemon and oregano from a tiny taverna had lingered in my memory. I wanted to recreate that sunny, herbaceous flavor in my own kitchen, but with a quick and easy weeknight twist. This one-pan lemon herb salmon with asparagus was born.

The beauty of this recipe is its simplicity. You toss everything on a single sheet pan, let the oven do the work, and in 20 minutes you have a restaurant-quality meal. The salmon comes out perfectly flaky, the asparagus is crisp-tender, and the lemon-herb butter melts into everything, creating a bright, savory sauce that ties it all together.

Whether you're a busy professional or a parent juggling a million things, this dish is a lifesaver. It's healthy, delicious, and requires minimal cleanup. Plus, it's versatile enough to swap in whatever veggies you have on hand. Let's dive in!

About the Ingredients

4 (6 oz / 170g) salmon fillets, skin on or off

Look for wild-caught salmon if possible; it has a firmer texture and richer flavor. If using frozen, thaw overnight in the fridge.

1 lb (450g) asparagus, woody ends trimmed

Choose spears that are bright green and firm. If asparagus is out of season, substitute with green beans or broccolini.

3 tbsp (45ml) olive oil, divided

Extra virgin olive oil adds a fruity note. You can also use avocado oil for a higher smoke point.

2 tbsp (30g) unsalted butter, melted

Use salted butter and reduce the added salt if you prefer. For a dairy-free option, use vegan butter or extra olive oil.

2 cloves garlic, minced

Fresh garlic is best, but 1/2 tsp garlic powder can work in a pinch.

1 lemon, zested and juiced (about 2 tbsp juice)

Meyer lemons are sweeter and less acidic; if using regular lemons, you might want a little extra juice.

2 tsp (2g) dried oregano

Greek oregano is more pungent. If using fresh, use 1 tbsp, chopped.

1 tsp (5g) salt, divided

Use kosher salt for even seasoning. Adjust to taste.

1/2 tsp black pepper, freshly ground

Freshly ground pepper adds a punch. Pre-ground works too, but use less.

1/4 cup (15g) fresh parsley, chopped (for garnish)

Flat-leaf parsley is more flavorful. You can also use dill or chives.

Tips & Tricks

• Pat the salmon dry with paper towels before seasoning to ensure it browns nicely and doesn't steam.
• Arrange the asparagus in a single layer on the pan so they roast evenly, not steam.
• Don't overcrowd the pan; if your sheet pan is small, use two pans or cook in batches to ensure proper browning.

Step-by-Step Instructions

1. Preheat Oven

Preheat your oven to 425°F (220°C). Position a rack in the middle. Line a large rimmed baking sheet with parchment paper for easy cleanup.

2. Season Asparagus

On the prepared pan, toss the asparagus with 1.5 tbsp olive oil, 1/4 tsp salt, and a pinch of pepper. Spread them in a single layer on one half of the pan.

3. Make Herb Butter

In a small bowl, combine the melted butter, minced garlic, lemon zest, 1.5 tbsp lemon juice, oregano, 1/2 tsp salt, and 1/4 tsp pepper. Stir well.

4. Season Salmon

Pat the salmon fillets dry. Brush each fillet with the remaining 1.5 tbsp olive oil and season with the remaining 1/4 tsp salt and a pinch of pepper.

5. Place Salmon on Pan

Arrange the salmon fillets on the other half of the pan, skin-side down if using skin-on. Drizzle the herb butter evenly over the salmon fillets.

6. Roast

Roast for 12-15 minutes, or until the salmon is opaque and flakes easily with a fork (internal temp 145°F/63°C), and the asparagus is crisp-tender and slightly charred at the edges.

7. Garnish and Serve

Remove from the oven. Squeeze the remaining lemon juice over everything, sprinkle with fresh parsley, and serve immediately.

Delicious Variations

• Swap asparagus for broccoli florets or green beans; adjust roasting time by a few minutes.
• Use fresh dill instead of oregano for a different herb profile.
• Add a splash of white wine to the herb butter for extra depth.
