Why Bake Costco Salmon?

There are a few reasons why baking is one of the best cooking methods for Costco salmon

  • It’s easy and requires minimal preparation or cleanup. Simply season the fillets, pop them in the oven, and you’re done.

  • Baking gently cooks the salmon through while keeping it tender and moist The fish comes out flaky and infused with flavor

  • It’s easy to bake many fillets at once, which is great for cooking for a lot of people or making meals ahead of time.

  • Hands-off cooking frees you up to focus on side dishes or other meal components while the oven does the work.

  • When you bake salmon instead of grilling or pan searing it, it doesn’t fall apart or dry out as quickly. It’s a very forgiving cooking method.

How Long to Bake Costco Salmon

The exact bake time depends on a few factors:

Thickness of the Fillet

Thicker salmon fillets will obviously require a longer bake time than thinner pieces Costco’s fresh salmon fillets are typically cut about 1 to 1 1/2 inches thick,

For a 1-inch thick salmon fillet, plan on baking for 18-22 minutes at 400°F.

1 1/2-inch thick fillets may need 22-28 minutes for full doneness.

Desired Doneness

  • For rare or medium rare salmon, bake for the minimum recommended time.

  • Medium or well done salmon will require a longer baking time, closer to the maximum.

  • I prefer my Costco salmon baked until just opaque and medium done all the way through. Around 20-22 minutes yields the texture I like best.

Bone-In vs Boneless

Salmon fillets cooked on the bone may take 2-5 minutes longer since the bones insulate the meat slightly. The bones do impart extra flavor though!

Portion Size

  • Individual 6-8 oz fillets will bake faster than a large 2-3 lb salmon roast.

  • Adjust bake times up for thicker, larger cuts of fish.

How to Bake Costco Salmon Perfectly Every Time

Follow these simple steps for flawlessly baked salmon fillets:

Step 1) Preheat oven to 400°F. Line a rimmed baking sheet with foil or parchment paper.

Step 2) Rinse salmon fillets and pat extremely dry with paper towels. Brush lightly with oil or melted butter.

Step 3) Season salmon generously with salt, pepper and any other desired herbs or spices.

Step 4) Place fillets skin-side down on the baking sheet. Bake for 18-25 minutes based on thickness.

Step 5) Check internal temp with a meat thermometer to ensure it reaches 145°F when done.

Step 6) Let salmon rest 5 minutes before serving.

And that’s seriously it! Beautifully cooked, flaky salmon ready in under 30 minutes.

Cooking Frozen Costco Salmon

It’s easy to go straight from freezer to oven with Costco’s individually vacuum sealed frozen salmon fillets.

Since frozen salmon takes longer to bake through, increase cook time to 25-35 minutes at 400°F for a 1-inch thick fillet.

As always, rely more on the internal temp than time. Bake frozen fillets until they register 145°F.

Checking Doneness of Baked Salmon

Using an instant read thermometer is the most foolproof way to assess doneness. But if you don’t have one, try these visual cues:

  • Salmon should flake easily and look opaque throughout when done.

  • Test for flakiness by poking the thickest part with a fork.

  • The exterior will appear lightly browned or caramelized.

  • Well done salmon will separate from the skin more easily.

Tips for Flavorful, Moist Salmon

  • Dry thoroughly and brush with oil or melted butter before seasoning. This helps the seasonings stick and promotes browning.

  • Use a non-stick pan or line pan with parchment paper to prevent sticking.

  • Brush with mayo or mustard instead of oil for extra browning and flavor.

  • Season generously with salt, pepper and spices or herb rubs. Salmon benefits from strong seasonings.

  • Bake at a high temp like 400°F to brown the exterior while keeping the interior moist.

  • Let rest before serving so juices can redistribute through the flesh.

Side Dishes for Baked Salmon

Here are some delicious options to accompany your baked Costco salmon:

  • Rice pilaf or quinoa
  • Roasted potatoes or sweet potatoes
  • Sauteed spinach or roasted Brussels sprouts
  • Mixed salad greens with vinaigrette
  • Steamed broccoli or asparagus

I also love serving sauces like chimichurri, aioli, pesto or teriyaki on the side for dipping. Fresh lemon or lime wedges are fantastic too.

Storing and Reheating Leftovers

You can safely store leftover baked salmon in the refrigerator for 3-4 days. Here are some ideas for enjoying leftovers:

  • Break into chunks and add to salads or rice bowls
  • Flake into pasta, risotto or frittatas
  • Stuff in lettuce wraps or sandwiches
  • Top with eggs for a protein packed breakfast
  • Reheat gently in the oven or microwave

For longer storage, you can freeze baked salmon for 2-3 months. Thaw overnight in the fridge before using.
