Costco Frozen Salmon Cooking Instructions
Cooking Costco’s frozen salmon is simple and flexible. You can bake, grill, air fry, or pan-fry it, even straight from the freezer. Below are the Costco frozen salmon cooking instructions for each method, ensuring tender, flaky results.
Oven Baking Instructions
From Frozen:
Preheat your oven to 425°F. Rinse fillets under cold water to remove ice crystals, then pat dry. Place skin-side down in a foil-lined baking dish, brush with oil, and season. Bake for 15 minutes covered, then 8–10 minutes uncovered until the internal temperature reaches 145°F.
From Thawed:
Thaw fillets in the fridge for 8–10 hours or in cold water for 20–30 minutes. Preheat the oven to 350°F. Brush with oil, season, and bake for 12–15 minutes in a foil-lined dish until flaky and 145°F internally.
Air Fryer Instructions
From Frozen:
Preheat the air fryer to 390°F. Place frozen fillets skin-side down in the basket and spray with oil. Cook for 7 minutes, then season and cook for 6–8 minutes more until 145°F. Thicker fillets may need up to 18 minutes.
From Thawed:
Thaw fillets as above. Preheat the air fryer to 400°F for farm-raised or 390°F for wild-caught. Brush with oil, season, and cook for 7–9 minutes until the internal temperature hits 145°F.
Grilling Instructions
From Frozen:
Preheat the grill to medium-high. Rinse and pat dry frozen fillets, then brush with oil. Grill for 10–12 minutes, flipping once, until the salmon flakes easily and reaches 145°F. Use foil to prevent sticking.
From Thawed:
Thaw fillets first. Preheat the grill to medium-high, oil the grates, and place fillets skin-side down. Grill for 5–7 minutes per side until the internal temperature is 145°F and the flesh is opaque.
Pan-Frying Instructions
From Frozen:
Rinse and pat dry frozen fillets. Heat a skillet over medium-high with oil, place fillets skin-side up, and cook for 4–5 minutes. Flip, season, and cook 7–9 minutes more until 145°F and flaky.
From Thawed:
Thaw fillets, then pat dry. Heat oil in a skillet over medium-high, cook skin-side up for 3–4 minutes, then flip and cook 3–4 minutes until 145°F. Season after flipping to avoid burning spices.

Tips for Perfect Costco Salmon
Rinse frozen fillets under cold water to remove ice crystals, preventing a waterlogged texture. Pat dry before cooking to ensure a crisp exterior. Use an instant-read thermometer to check for 145°F doneness.
Season after partial cooking when pan-frying to avoid burning spices. For extra flavor, try a glaze like maple syrup and soy sauce. Line baking dishes with foil for easy cleanup.
Store fillets in the freezer until ready to cook. Thaw in the fridge for 8–10 hours or in cold water for 20–30 minutes if needed. Never refreeze thawed salmon to maintain quality.
Enhancing Your Salmon Dish
Costco’s salmon pairs well with simple sides like roasted vegetables or quinoa. A squeeze of fresh lemon juice adds a bright, zesty touch. Try a dill or garlic butter sauce for extra richness.
For a special touch, top with fresh herbs like parsley or thyme before serving. A glaze of honey and Dijon mustard creates a sweet-savory crust. These additions elevate the dish without much effort.
Serve salmon over a salad for a light meal or with rice for something heartier. For gatherings, flake cooked salmon into tacos or bowls. It’s versatile and crowd-pleasing.
Nutritional Benefits
A 6 oz serving of Costco’s Wild Sockeye Salmon has 290 calories, 15 grams of fat, and 36 grams of protein. It’s rich in omega-3 fatty acids, supporting heart health. The Atlantic Salmon offers similar benefits with a milder flavor.
Both varieties are free of added sugars and low in sodium (80 mg per serving). They contain no fiber or carbs, making them keto-friendly. Always check for small bones, though fillets are typically boneless.
Frozen salmon retains the same nutrients as fresh, making it a healthy choice. It’s naturally gluten-free and fits paleo or Whole30 diets. Pair with nutrient-dense sides for a balanced meal.
Common Mistakes to Avoid
Don’t rinse salmon excessively, as it can become waterlogged. Avoid cooking frozen salmon in a slow cooker, as it stays in the danger zone (40–140°F) too long. Always cook to 145°F for safety.
Don’t season frozen salmon before cooking in a skillet, as spices may burn. Overcooking can dry out the fish, so check doneness with a fork or thermometer. Thawing too quickly at room temperature risks bacterial growth.
Use heavy-duty foil for oven baking to trap steam effectively. Don’t microwave frozen salmon, as it cooks unevenly. Follow Costco frozen salmon cooking instructions for the best texture and flavor.
Costco Salmon for Every Occasion
Costco’s frozen salmon is perfect for quick weeknight meals or meal prepping. A single fillet serves one, while a 3-pound bag feeds a crowd. It’s ideal for family dinners or parties.
Try the sockeye for a bold flavor or the Atlantic for a milder taste. Both work in recipes like salmon patties or casseroles. The individual portions make it easy to cook just what you need.
Keep a bag in your freezer for last-minute meals. It’s a healthy, affordable option that doesn’t skimp on taste. With minimal prep, you’ll have a nutritious dish ready fast.
