Air Fryer Hamburgers

These air fryer hamburgers are perfect for when it's too cold to grill and you're craving a juicy burger! The butter and bouillon mixture gives these air fryer hamburger patties a dark grilled color and deep beefy flavor. Add your favorite seasonings, if desired, but these are delicious as is! If you'd like to add cheese, turn off the air fryer once the patties are done and let the residual heat melt the cheese. Make sure you use cold meat, straight from the fridge, for best results.
