Preheat your air fryer to 350 degrees F. This initial step ensures that your salmon bites will cook evenly and develop that wonderful crisp on the outside without overcooking the inside.
Make the remoulade sauce by mixing all the sauce ingredients in a bowl. Combine the mayonnaise, stone ground mustard, milk, horseradish, celery seed, onion powder, dried parsley flakes, white vinegar, paprika, and cayenne pepper. Stir well and refrigerate for at least 30 minutes. This allows the flavors to meld together, resulting in a delicious dipping sauce.
Prep your salmon by removing the skin if necessary and cutting it into uniform 1-inch cubes. This ensures even cooking. Place the cubes into a bowl and drizzle with olive oil. Season generously with salt, pepper, garlic powder, and smoked paprika. Gently toss the salmon to coat each piece evenly.
Spray the air fryer basket with olive oil cooking spray to prevent sticking. Add the seasoned salmon cubes in a single layer, making sure they have a bit of space between them for even air circulation. This step is crucial for achieving that crispy exterior.
Air fry at 350 degrees F for about 6 to 7 minutes. Halfway through cooking, gently toss the salmon with tongs to ensure even browning and cooking. The salmon should be cooked through and flake easily with a fork when done.
Serve your Air Fryer Salmon Bites hot, accompanied by the chilled remoulade sauce on the side for dipping. Enjoy the combination of the crispy salmon with the creamy, tangy sauce!
