The Ingredients 

  1. Dried Thyme: Dried thyme adds a subtle, earthy flavor that complements the taste of the salmon. It’s not overpowering and helps to enhance the natural flavors of the fish. This herb is common in many fish recipes due to its versatility and ability to blend well with other seasonings.
  2. Costco Kirkland Wild Salmon Fillets: The star of the show, wild salmon is not only delicious but also packed with healthy omega-3 fatty acids. Costco’s Kirkland brand is known for its quality, and the 1-inch thickness of these fillets ensures a good balance of heat distribution during cooking and a perfect flaky texture when done.
  3. Diamond Crystal Kosher Salt/Sea Salt: Salt is an essential seasoning that brings out the flavor of the other ingredients. Diamond Crystal Kosher salt has a larger grain size than table salt, allowing for better control when seasoning. Alternatively, sea salt can be used, which may impart a slight mineral flavor beneficial to the overall taste of the dish.
  4. Olive Oil: Olive oil serves two purposes in this recipe. First, it helps to prevent the salmon from sticking to the pan or grill. Second, it contributes to the richness of the dish and enhances the absorption of the fat-soluble flavors from the other ingredients. It also adds some heart-healthy monounsaturated fats.
  5. Freshly Ground Black Pepper: This provides a hint of heat and depth of flavor. Freshly ground black pepper is often more flavorful than pre-ground pepper and can elevate the dish by adding a layer of complexity to its taste profile.
  6. Garlic Powder: Garlic powder offers a concentrated garlic flavor that pairs wonderfully with salmon. It’s an easy way to add a punch of flavor without the need to peel and mince fresh garlic. The powder disperses evenly over the fillets, ensuring a consistent garlic taste in every bite.

Step by Step Instructions 

Step 1: Preheat the Oven

Begin by preheating your oven to 375°F (190°C). This initial step sets the stage for a perfectly cooked Costco salmon that’s both tender and flavorful.

Step 2: Prepare the Baking Sheet

Line a baking sheet with either parchment paper or aluminum foil. To prevent sticking and ensure easy cleanup, lightly grease the lined sheet with a thin layer of oil. This essential prep work guarantees a hassle-free cooking experience.

Step 3: Place the Salmon

Lay the salmon fillets onto the prepared baking sheet with the skin side facing down. Proper placement on the baking sheet ensures even cooking and preserves the salmon’s delicate texture.

Step 4: Drizzle with Olive Oil

Drizzle one tablespoon of olive oil over each fillet. Gently rub the oil into the salmon, ensuring an even and flavorful coating. This step not only enhances the salmon’s taste but also helps achieve a crispy exterior.

Step 5: Season to Perfection

For a burst of flavor, sprinkle the salmon fillets with a well-balanced combination of salt, pepper, garlic powder, and dried thyme. These seasonings will infuse your Costco salmon with irresistible aromas and taste.

Step 6: Bake with Precision

Slide the prepared baking sheet into the preheated oven. Allow the salmon to bake for approximately 15 minutes, or until it reaches an internal temperature of 145°F (62°C). This is the moment when the salmon achieves its exquisite flakiness and succulence.

Step 7: Plate and Serve

Once your salmon is baked to perfection, carefully remove the baking sheet from the oven. Using a spatula, gently transfer the fillets to individual plates.

Notes 

  • For an even more pronounced flavor, try marinating the salmon with your preferred seasonings for 20 minutes before baking.
  • If you don’t have olive oil on hand, any type of neutral cooking oil will work just fine. However, olive oil is preferable as it adds a nice richness to the dish.
  • To make this recipe gluten-free, ensure that you are using a gluten-free seasoning blend or make your seasoning with ingredients like garlic powder, sea salt, and freshly ground black pepper.
  • For an extra touch of decadence, top each fillet with a pat of butter before baking. This will add a subtle richness and additional juiciness to the salmon.

How to store Costco Salmon?

Once cooked, Costco Salmon can be stored in an airtight container in the fridge for up to 3 days. Alternatively, you can freeze the salmon for future use. To do this, wrap each fillet tightly with either plastic wrap or aluminum foil before placing it into a freezer-safe bag or container. When ready to eat, simply thaw out the salmon in their refrigerator overnight and reheat it using your preferred method.

For optimal safety, make sure the salmon is fully cooked before storing and that you refrigerate or freeze it as soon as possible after cooking. This will help to maintain its freshness, flavor, and texture. Additionally, leave cooked salmon out at room temperature for up to two hours. Doing so can significantly reduce its shelf life and increase the risk of foodborne illnesses.

Variations 

  1. Use different herbs and spices to season the salmon such as oregano, basil, or rosemary.
  2. For a sweeter flavor, add a teaspoon of honey or brown sugar to the olive oil before coating the salmon fillets.
  3. For an Asian-inspired dish, mix soy sauce, rice vinegar, ginger powder, garlic powder, and sesame oil for a marinade.
  4. Try topping the salmon with a lemon-herb butter sauce or a creamy dill sauce for a luxurious finish.
  5. Mix panko breadcrumbs with melted butter and Parmesan cheese for a crunchy crust on top of the fillets.
  6. For added texture and flavor, sprinkle some capers or sliced almonds onto the salmon before baking.
  7. Serve with roasted vegetables, grilled asparagus, or a fresh salad for a complete meal.
  8. To give the salmon an extra smoky flavor, cook it on the grill over medium heat for 15 minutes.
  9. Try baking the salmon in a foil pouch with some citrus slices and herbs for an effortless meal.
  10. Use leftover cooked salmon to make delicious fish cakes or salmon quiche.
  11. For a zesty finish, sprinkle some freshly chopped parsley onto the cooked fillets before serving.
