About This Recipe

This baked salmon recipe is one of the most popular healthy dinner ideas in the US — and it takes just 30 minutes from fridge to table. A compound butter made with garlic, fresh herbs, lemon zest, and Dijon mustard melts into the salmon as it bakes, basting every inch of the fillet in rich, aromatic flavor. The result is salmon that's perfectly flaky inside, with a lightly golden top and a bright, restaurant-quality finish. Paired with asparagus baked on the same sheet, it's a complete dinner with minimal dishes.

Ingredients

2 salmon fillets (170g / 6oz each) 3 tbsp unsalted butter, softened 3 garlic cloves, minced 2 tbsp fresh parsley, chopped 1 tbsp fresh dill, chopped 1 lemon (zest + juice) 1 tsp Dijon mustard Salt & black pepper 1 bunch asparagus 1 tbsp olive oil Lemon wedges to serve

Step-by-Step Instructions

  1. 1

    Preheat the oven and prep the pan

    Heat the oven to 400°F (200°C). Line a large baking sheet with aluminum foil — this makes cleanup effortless and reflects heat for better browning.

  2. 2

    Make the herb butter

    In a small bowl, combine the softened butter with minced garlic, chopped parsley, dill, lemon zest, Dijon mustard, ½ tsp salt, and black pepper. Mix until thoroughly combined. The butter should be spreadable and fragrant.

  3. 3

    Prep the asparagus

    Snap off the woody ends of the asparagus (bend each spear and it'll break at the natural point). Toss with olive oil, salt, and pepper. Spread in a single layer on one side of the baking sheet.

  4. 4

    Season and top the salmon

    Pat the salmon fillets dry with paper towels — this is crucial for a golden top. Season the flesh side with salt and pepper, then place skin-side down on the other half of the baking sheet. Spread the herb butter generously over the top of each fillet, covering it completely.

  5. 5

    Bake to perfection

    Bake for 12–15 minutes depending on the thickness of your fillets. The salmon is done when it flakes easily at the thickest point with a fork and the flesh has changed from translucent to opaque. For a slightly caramelized top, broil for the last 2 minutes.

  6. 6

    Finish and serve

    Squeeze fresh lemon juice over the salmon and asparagus. Serve immediately with the pan juices spooned over the top.

Pro Tips

🏆 Tips for Perfect Baked Salmon
  • Bring salmon to room temperature for 15 minutes before baking — cold fish straight from the fridge bakes unevenly.
  • Don't overbake. The single most common mistake with salmon is cooking it past 145°F (63°C) internal temperature, where it dries out. Pull it when it still looks slightly translucent in the very center — it will finish cooking from residual heat.
  • For crispy skin, place the salmon skin-side DOWN and don't move it during baking.
  • The herb butter freezes beautifully — roll it into a log in plastic wrap and freeze for up to 3 months. Slice off rounds whenever you need them.

Frequently Asked Questions

The most reliable method is an instant-read thermometer — aim for 125-130°F (52-54°C) for medium (slightly translucent center) or 145°F (63°C) for fully cooked. Visually, the flesh should change color from bright pink/translucent to pale pink/opaque, and it should flake easily when pressed with a fork.
Yes — thaw overnight in the refrigerator, then pat very dry before cooking. Frozen salmon often releases more moisture, so thorough drying is especially important. Fresh or previously frozen salmon both work well in this recipe.
Asparagus (as in this recipe), roasted broccoli, garlic mashed potatoes, steamed rice, quinoa, or a simple green salad. For a low-carb option, cauliflower rice or zucchini noodles work beautifully with the herb butter sauce.
