How to Cook Salmon at 425°F: A Comprehensive Guide

Cooking salmon in the oven at 425°F is a simple and effective way to prepare this delicious and nutritious fish. Here’s a step-by-step guide to ensure you achieve perfectly cooked salmon every time.

Preparing the Salmon

Before you start cooking, make sure your salmon fillets are ready. Here are some preparatory steps:

  • Remove Pinbones: If your salmon fillets have pinbones, remove them using fish bone tweezers[3][5].
  • Pat Dry: Pat the salmon fillets dry with clean paper towels to remove excess moisture. This helps the seasonings adhere better and promotes even cooking[1][3][5].
  • Seasoning: Brush the salmon with oil (such as avocado oil or olive oil) and season with your desired spices. Common seasonings include salt, black pepper, garlic powder, onion powder, and thyme[1][3][5].

Cooking the Salmon

For Fresh Salmon

  • Preheat the Oven: Preheat your oven to 425°F (220°C). Line a baking sheet or baking dish with parchment paper or aluminum foil, and if using foil, spray it with cooking spray to prevent sticking[1][3][5].
  • Bake the Salmon: Place the salmon fillets on the prepared baking sheet. For 6-ounce fillets that are about 1 inch thick, bake for approximately 12-15 minutes. The exact time can vary based on the thickness of the fillets:
  • For 1-inch thick fillets, bake for 12-14 minutes[3].
  • For thinner fillets, reduce the baking time to prevent overcooking[1][3].
  • Broil for Browning: If you want a crispy top, increase the oven to broil and cook for an additional 2 minutes after the initial baking time[1].

For Frozen Salmon

  • Preheat the Oven: Preheat your oven to 425°F (220°C).
  • Bake the Salmon: Place the frozen salmon fillets on the prepared baking sheet. Baking frozen salmon typically takes longer:
  • For 6-ounce fillets, bake for about 20-25 minutes[4].
  • Check the salmon after 15 minutes; if it is still frozen solid, let it parcook for a few more minutes before seasoning and continuing to bake uncovered[4].

Checking for Doneness

To ensure your salmon is cooked to perfection, use the following methods:

  • Internal Temperature: Use an instant-read thermometer to check the internal temperature. For medium doneness, aim for 125-130°F (52-54°C), and for fully cooked, aim for 140-145°F (60-63°C)[1][3][5].
  • Visual Cues: Check that the flesh turns from translucent to opaque and flakes easily with a fork. The center should not be icy or translucent[3][5].

Additional Tips

  • Even Cooking: Use salmon fillets that are similar in size and thickness to ensure even cooking[1][3][5].
  • Avoid Overcooking: Slightly undercooking the salmon is key to keeping it tender. Wild salmon, with less fat, is more prone to drying out, so monitor it closely[1][3].
  • Garnish and Serve: Once cooked, garnish with a squeeze of fresh lemon juice and a sprinkle of fresh chopped parsley for added flavor[1][5].
