Set your air fryer to 360 degrees F (182°C) for 1-2 minutes. Some models require preheating, while others don't. If yours does, let it warm up for a few minutes.
Slice the whole bagel in half with a serrated knife. If you prefer a little extra crunch or flavor, lightly brush the cut sides with butter or olive oil, but this step is optional.
Arrange the bagel halves in the preheated air fryer basket, or air fryer oven cut-side up. Ensure they’re not overlapping or touching too closely to allow for even toasting.
Cook the bagels at 360°F (182°C) for about 5-6 minutes. They might need an additional minute if you didn't preheat the air fryer.
After 4 to 5 minutes, check the bagels. If you like them more toasted, you can add another minute. Be careful not to overdo it; they can quickly go from perfectly toasted to burnt.
Once they're toasted to your satisfaction, carefully remove the bagels from the air fryer. They will be hot, so it's advisable to use tongs or a spatula.
Now's the fun part – add your favorite toppings. Whether it’s classic cream cheese, a savory spread, or something sweet, the choice is yours!
