One-Pan Lemon Herb Salmon with Asparagus

This is my weeknight hero: crisp-skinned salmon fillets and tender asparagus roasted together on one pan with lemon, garlic and herbs. It tastes like a restaurant plate but the whole thing is done in about 25 minutes, with barely any washing up.

The secret is a quick hot sear on the salmon skin first, then everything finishes in the oven. The lemon turns jammy at the edges and the garlic gets sweet – squeeze it all over at the end and you will not need any other sauce.

Ingredients

• 4 salmon fillets (about 150 g / 5 oz each), skin-on
• 450 g (1 lb) asparagus spears, tough ends trimmed
• 2 tbsp (30 ml) olive oil, divided
• 1 tsp salt, plus more to taste
• 1/2 tsp freshly cracked black pepper
• 1 tsp garlic powder
• 1 tsp dried oregano
• 1 lemon, half cut into thin slices, half juiced
• 3 garlic cloves, thinly sliced
• 2 tbsp (30 g) cold butter, cut into small pieces
• 2 tbsp fresh parsley, chopped
• 1 tbsp fresh dill, chopped (optional)

Instructions

1. Heat the oven: Preheat to 220 C (425 F). Line a large rimmed baking sheet with foil or parchment for easy cleanup.
2. Season everything: Pat the salmon fillets very dry with paper towels. Toss the asparagus with 1 tbsp of the olive oil, 1/2 tsp salt and a few grinds of pepper; spread it on the pan in a single layer.
3. Sear the salmon skin: Heat the remaining 1 tbsp olive oil in an ovenproof skillet over medium-high heat until shimmering. Lay the salmon skin-side down and sear for 3-4 minutes without moving it, until the skin releases easily and looks crisp.
4. Add flavour: Flip the fillets onto their sides or backs. Season the flesh with salt, pepper, garlic powder and oregano. Scatter the garlic slices, lemon slices and butter pieces around the salmon.
5. Roast: Transfer the skillet to the oven for 7-9 minutes, until the salmon flakes gently with a fork and reads 52-54 C (125-130 F) in the thickest part – it keeps cooking off the heat.
6. Finish: Squeeze the lemon juice over everything, shower with parsley and dill, and serve right from the pan with the jammy lemon slices and melted garlic butter spooned over.

Tips for the best result

• Pat the salmon skin completely dry – moisture is the enemy of crisp skin.
• Buy center-cut fillets of similar thickness so they finish at the same time.
• Do not move the salmon while it sears; it releases on its own when the skin is crisp.

Storing and reheating

Refrigerate leftovers in an airtight container for up to 2 days. Reheat gently in a 160 C (325 F) oven until just warm; overheating dries the salmon out.

Frequently asked questions

Can I use skinless salmon?

Yes – skip the sear and roast the fillets for 10-12 minutes, basting with the butter halfway through.

How do I know the salmon is done?

It should flake easily with a fork and look just opaque in the center. A thermometer is the surest way: 52-54 C (125-130 F) for medium.

What can I use instead of asparagus?

Green beans, broccoli florets or halved cherry tomatoes all roast on the same pan in the same time.
