Grate the onion on a box grater or process it in a small food processor so that it’s as finely chopped as it can be. Grate the garlic as well.
Mix turkey, breadcrumbs, onion, garlic, Worcestershire sauce, sweet and smoked paprika, mustard, egg, salt, and pepper. Mix with the hand until well combined.
Form four even patties, they should each weigh about 150 g/ 5.3 oz. (Note 4)
Preheat the air fryer according to its instructions (mine needs 3 minutes). Spray the fryer’s basket with oil. Place the patties inside and spray them lightly with oil as well. (Note 5)
Cook for 7 minutes. Flip and cook for another 5 minutes. The internal temperature should be 73 degrees Celsius/ 165 degrees Fahrenheit.
To make a cheeseburger, place a slice of cheese on each burger during the last 30 – 60 seconds of the cooking time.
Burgers:
While the burgers cook, prepare the toppings.
Slightly toast the bun halves in a grill pan for about 1-2 minutes.
Slice the tomatoes and sour cucumbers, cut the red onion into rings.
Wash and dry the lettuce leaves.
Mix ketchup and mustard in a small bowl. (Note 5)
Smear the lower half of the buns with the ketchup mix. Cover with lettuce, add 1 or 2 tomato slices. Place the patty on top. Add onion rings and sour cucumber slices. Cover with the other bun half.
Serve immediately.
Notes
The nutrition is calculated including cheese.
I prefer sweet smoked paprika, but hot to taste is fine as well.
Cheddar, Pepper Jack, aged Gouda, Swiss, blue cheese, or even feta.
The patties can be frozen now. See the blog post for more information on that.
If you don’t have an oil spray, brush the basket and the patties with a little oil.
BBQ sauce or sweet chili sauce can be used instead of the ketchup mustard mix.
