Measure the Rice Chex, Pretzel Goldfish Crackers, Oyster Crackers and Cashews into a large bowl.
Microwave the butter until it is melted.
Into the butter, whisk in the Worcestershire sauce, lemon juice, Old Bay Seasoning, parsley, garlic powder and salt.
Pour the buttery sauce mixture evenly over the snack mix.
Stir well to combine.
Pour the Chex mix into the basket of your air fryer.
Fry the Chex mix in your air fryer at 300 degrees F, stirring and shaking the basket a couple of times to make sure the snack mix cooks evenly.
Air fryers vary, so be sure to watch your Chex mix closely so as not to burn it. My air fryer cooked my Chex mix perfectly in about 18 minutes at 300 degrees F.
