Step 1

Put the ground turkey in a bowl. Add the diced onion, spicy mustard, Worcestershire sauce, salt and pepper. Mix with your hands.

Step 2

Form the meat into patties. Make three patties for 6 ounce burgers or four patties for 4 ounce burgers.

Step 3

Flatten the patties and make a little bit of a depression in the center of the patty.

Step 4

(Optional) Refrigerate for 30 minutes to make the patties firmer before cooking if desired.

Step 5

Preheat the air fryer at 360 degrees F for 3 minutes.

Step 6

Add the patties to the air fryer, making sure they are in a single layer. Cook at 360 degrees F for 17 minutes.

Step 7

Flip the patties once, after 10 minutes.

Step 8

Use an instant read thermometer and check the temperature of the patty in the center or the thickest part. The patties are done when they reach 165 degrees F.

Step 9

If they aren't done continue to cook for another 3 minutes and recheck them.

Step 10

Serve on a bun with your favorite burger toppings.
