How long to cook frozen salmon from Costco?

Cooking frozen salmon fillets from Costco to perfection requires knowing some key information like the cut, thickness, whether it is skin-on or skinless, and if you are baking, broiling, grilling or pan frying. With the right technique, frozen Costco salmon can turn out moist, flaky and delicious.

Factors That Affect Cooking Time

Here are the main factors that determine how long to cook frozen salmon from Costco:

  • Thickness – Thicker cuts take longer to cook than thinner fillets or portions.
  • Skin on vs skinless – Skin insulates the flesh so skin-on fillets take a little longer.
  • Cooking method – Grilling or broiling cooks faster than baking or pan-frying.
  • Doneness – Cook longer for well-done salmon vs medium or medium rare.
  • Quantity – Cooking multiple fillets together increases overall cooking time.

Recommended Cooking Times

Here are general guidelines for how long to cook frozen salmon fillets of varying thickness using different cooking methods:

Thickness Baking Broiling Grilling Pan Frying
1/4 inch 8-12 minutes 6-8 minutes 4-6 minutes 6-8 minutes
1/2 inch 12-15 minutes 10-12 minutes 8-10 minutes 8-10 minutes
3/4 inch 15-20 minutes 12-15 minutes 10-12 minutes 10-12 minutes
1 inch 20-25 minutes 15-18 minutes 12-15 minutes 12-15 minutes

These times are based on cooking salmon to medium doneness. For well-done salmon, cook for 2-3 minutes longer.

Tips for Cooking Frozen Salmon from Costco

Follow these tips to ensure frozen salmon turns out moist and flakes apart beautifully when cooked:

  • Thaw slowly overnight in the fridge, not at room temp.
  • Pat dry before cooking to prevent steaming.
  • Brush with oil or rub with spices/herbs for flavor.
  • Preheat oven or grill before cooking.
  • Use a meat thermometer – aim for 130°F (medium rare) to 145°F (medium).
  • Let rest 5 minutes before serving.

Conclusion

Cooking frozen salmon fillets from Costco is easy once you know the thickness and cooking method. Thinner portions will be done faster than thick cuts. Grilling, broiling or pan frying take less time than baking. Aim for 8-12 minutes per 1/4 inch thickness for most cooking methods and medium doneness. Defrosting properly, oiling the fish, preheating cooking surfaces, and using a thermometer will ensure perfect results.
