Jump to RecipeCostco Stuffed Salmon Recipe Ingredients
- 4 teaspoons extra virgin olive oil, divided
- 5 ounces fresh baby spinach (about 5 cups)
- 1 clove garlic, minced (about 1 teaspoon)
- ¾ teaspoon kosher salt, divided
- ½ teaspoon ground black pepper, divided
- Pinch red pepper flakes
- ¼ cup reduced-fat cream cheese
- ¼ cup shredded part-skim mozzarella cheese
- ¼ cup finely grated Parmesan
- 4 (6 ounce) salmon fillets, skin off or on
How To Make Costco Stuffed Salmon
- Prep the oven and start the filling: Preheat your oven to 425°F. Line a large, rimmed baking sheet with parchment paper. Heat 2 teaspoons of the olive oil in a medium non-stick skillet over medium-high heat.
- Wilt the spinach: Add the spinach to the hot skillet in large handfuls, stirring often until it wilts down completely. Stir in the minced garlic, 1/4 teaspoon of salt, 1/4 teaspoon of black pepper, and the red pepper flakes. Cook for 30 seconds until fragrant.
- Make the cheese filling: Remove the pan from the heat. Stir in the cream cheese until it melts and combines smoothly with the spinach. Add the mozzarella and Parmesan cheese and stir until everything is melted and looks like a creamy spinach dip.
- Prepare the salmon: Pat the salmon fillets dry. With a small, sharp knife, make a deep cut lengthwise down the middle of each fillet to create a pocket. Be careful not to cut all the way through.
- Stuff the salmon: Place the salmon fillets on the prepared baking sheet. With a small spoon, divide the spinach and cheese mixture evenly, stuffing it into the pocket of each fillet.
- Season and bake: Drizzle the remaining 2 teaspoons of olive oil over the stuffed fillets. Sprinkle them with the remaining 1/2 teaspoon of salt and 1/4 teaspoon of black pepper. Place the baking sheet in the oven and bake for 8 to 10 minutes, or until the salmon is opaque and flakes easily with a fork.
Recipe Tips
- How to not overcook salmon? Salmon cooks very quickly. The best way to check for doneness is to gently press on the thickest part with a fork. If it begins to flake easily, it’s done. The internal temperature should be around 135-140°F for a moist, tender result.
- How to create the pocket easily? Use a small, sharp paring knife. Place the salmon fillet flat on your cutting board and hold it steady with one hand while you carefully slice horizontally into the side of the thickest part to create the pocket.
- Can I use frozen spinach? Yes. Thaw a 10-ounce package of frozen chopped spinach and squeeze it very dry to remove as much water as possible. Then, you can mix it directly with the garlic, seasonings, and cheeses without the initial wilting step.
- Can I make this in an air fryer? Absolutely. Prepare the stuffed salmon as directed. Place the fillets in the air fryer basket and cook at 400°F for 7-9 minutes, until the salmon is cooked through.

How To Store Stuffed Salmon
Refrigerate: Place leftover stuffed salmon in an airtight container in the refrigerator for up to 1 day. Reheat: For the best results that prevent the salmon from drying out, gently reheat the fillets on a baking sheet, loosely tented with foil, in a 350°F oven until just warmed through.
