Ingredient Checklist
- 6 tablespoons mayonnaise – I prefer Sir Kensington for its rich flavor.
- 2 tablespoons drained capers – Minced for that perfect bite.
- 2 teaspoons fresh lemon juice – Brightens up the flavors.
- 16 ounces skinless salmon fillet – If frozen, make sure to thaw it and cut into 4 pieces.
- 1 teaspoon kosher salt – Divided to season the salmon.
- 2 large egg whites – Lightly beaten to help the panko adhere.
- 1 cup seasoned panko – Or gluten-free panko, for the crunch factor.
- Olive oil spray – A light mist to ensure crispiness.
- 4 whole wheat buns – Or gluten-free buns, whichever suits your preference.
- 4 butter lettuce leaves – For freshness and crunch.
What You’ll Need (Gear)
- Air fryer – The star of the show for cooking the salmon perfectly.
- Mixing bowls – For combining your ingredients.
- Measuring spoons – Accurate measurements make all the difference.
- Spatula – For flipping and serving the salmon.
- Knife and cutting board – For prepping your ingredients.
How to Prepare Air Fryer Salmon Fish Sandwich

Step 1: Prepare the Caper Mayonnaise
In a mixing bowl, combine the mayonnaise, minced capers, and fresh lemon juice. Stir until well mixed. This creamy spread will add a zesty kick to your sandwich.
Step 2: Season the Salmon
Sprinkle the skinless salmon fillets with half of the kosher salt. This step is crucial as it enhances the flavor of the fish.
Step 3: Bread the Salmon
In a separate bowl, beat the egg whites. Dip each piece of salmon into the egg whites, ensuring they are well coated. Then, roll the salmon in the seasoned panko, pressing gently to adhere the breadcrumbs to the fish.
Step 4: Air Fry the Salmon
Preheat your air fryer to 400°F (200°C). Lightly spray the air fryer basket with olive oil spray to prevent sticking. Place the breaded salmon pieces in the basket in a single layer. Spray the tops lightly with olive oil spray to help them crisp up. Air fry for about 10-12 minutes, or until the salmon is cooked through and the panko is golden brown.
Step 5: Assemble the Sandwiches
While the salmon is cooking, lightly toast your whole wheat or gluten-free buns. Once the salmon is ready, spread the caper mayonnaise on the bottom half of each bun. Add a piece of crispy salmon, top with a butter lettuce leaf, and cover with the top bun.
Step 6: Serve and Enjoy!
Your Air Fryer Salmon Fish Sandwich is ready to be served! Pair it with your favorite sides or enjoy it on its own for a delicious meal.
Easy Ingredient Swaps

- Use Greek yogurt instead of mayonnaise for a lighter spread.
- Swap fresh salmon for canned salmon if you’re short on time.
- Try dill pickles instead of capers for a different flavor profile.
- Use regular breadcrumbs if panko is unavailable.
Watch Outs & How to Fix
When preparing your Air Fryer Salmon Fish Sandwich, it’s essential to keep an eye on the salmon as air fryers can vary in cooking times. If the panko looks overly dark before the salmon is fully cooked, cover it loosely with foil to prevent burning while the fish finishes cooking. Additionally, if you find the salmon is still raw in the center after the cooking time, simply air fry for another 2-3 minutes, checking periodically.
Keep-It-Fresh Plan
To keep your Air Fryer Salmon Fish Sandwich fresh, store the ingredients separately in airtight containers in the refrigerator. The salmon will stay fresh for up to 2 days. Reheat the salmon in the air fryer for a few minutes to restore its crispiness before assembling your sandwich. The caper mayonnaise can also be made ahead of time and stored for up to a week.
