Add brats to the air fryer making sure to leave room between each brat for the air to circulate.
Cook at 400° F(204°C) for 8 minutes, turning them over half way through. They should be a golden brown and 165 degrees F(74°C).
Notes
All air fryers are a bit different. Cooking times may vary slightly, if you know your air fryer tends to run a little cold or a bit hot try to factor that into the recipe. It may take a time or two to find the perfect time.
Brats should have an internal temperature of 165°F(74°C) to be safe to eat. It is okay for there to be a slight pink inside as long as they are up to the correct temperature. They should be a light golden brown when done. If they are leathery and wrinkled then they are overcooked.
No pre-heating is necessary in this recipe, which is great because there's no extra time waiting for it to get hot!
I wouldn't recommend making these in advance. Brats are best when they're still hot and juicy, so try to make these as close to when you'll eat them as possible.
All air fryers have different wattage and may cook at different rates. You may need to adjust the time or temp for the best results.
