Add the green beans, seasonings, and butter to a bowl. Mix with tongs.
Add to the air fryer cooking basket. Cook for 6 minutes at 400 degrees per side.
All of the spice mixes should be used to taste. In this recipe, I'm using a salt-free blend so 1 tbsp per 12oz of vegetables is great. However, for blends that have salt, I'd use 1 tsp per pound of veggies and add more depending on your preferences.
