Instructions

1. Preheat the Oven

Preheat your oven to 400°F (200°C). Line a large sheet pan with parchment paper or foil for easy cleanup.

2. Prepare the Potatoes

In a large bowl, toss the halved baby potatoes with olive oil, garlic powder, paprika, salt, and black pepper until evenly coated.

Spread the potatoes across the sheet pan in a single layer.

3. Roast the Potatoes First

Place the sheet pan in the oven and roast the potatoes for 15 minutes. This step ensures they become crispy and fully cooked.

4. Prepare the Brown Butter

While the potatoes roast, melt the butter in a small saucepan over medium heat.

Continue cooking until the butter turns golden brown and develops a nutty aroma, about 3–4 minutes.

Stir in minced garlic and lemon juice, then remove from heat.

5. Season the Salmon

Pat the salmon fillets dry with paper towels.

Brush them lightly with olive oil, then season with salt, pepper, and paprika.

6. Add Salmon and Asparagus to the Pan

Remove the sheet pan from the oven.

Push the potatoes to one side and place the salmon fillets on the other side of the pan.

Add the asparagus next to the salmon.

7. Season the Asparagus

Drizzle the asparagus with olive oil and sprinkle with salt, pepper, and grated parmesan cheese.

8. Add Lemon Brown Butter

Drizzle the prepared brown butter mixture over the salmon fillets.

Top each fillet with a slice of fresh lemon.

9. Roast the Entire Sheet Pan

Return the pan to the oven and roast for 12–15 minutes, or until the salmon flakes easily with a fork and the asparagus is tender.

10. Garnish and Serve

Sprinkle fresh chopped parsley over the entire dish.

Serve immediately with extra lemon wedges if desired.

Tips for the Best Sheet Pan Salmon

Use Even-Sized Potatoes

Cut the potatoes into uniform sizes so they cook evenly and become crispy at the same time.

Don’t Overcook the Salmon

Salmon cooks quickly. When it flakes easily with a fork, it’s ready.

Space Matters

Avoid overcrowding the sheet pan. Proper spacing helps vegetables roast instead of steam.

Choose Fresh Salmon

Fresh salmon will provide the best flavor and texture. Look for bright pink flesh and a mild ocean scent.
