If you're looking for the quickest and most delicious meal, look no further than your air fryer. This salmon cooks quickly and comes out perfectly cooked on the inside with a flaky top crust. The sweet mustard topping makes this one of our favorite air fryer dishes.
Season salmon all over with salt and black pepper. In a small bowl, whisk garlic, mustard, brown sugar, oil, and thyme to combine. Spread garlic mixture on top of salmon.
In an air-fryer basket, arrange salmon. Cook at 400° until desired degree of doneness, about 10 minutes.
