Measure 2 cups of Rice Chex, 1 cup of Pretzel Goldfish Crackers, 1 cup of Oyster Crackers, and 1 1/2 cups of Cashews into a large bowl.
Microwave 6 tbsp of unsalted butter until completely melted.
Whisk 1 tbsp Worcestershire sauce, 2 tsp lemon juice, 1 1/2 tsp Old Bay Seasoning, 2 tsp finely chopped parsley, and 1/2 tsp garlic powder into the melted butter.
Pour the buttery sauce mixture evenly over the snack mix in the bowl.
Stir well to combine all ingredients thoroughly.
Pour the Chex mix into the basket of your air fryer.
Air fry the Chex mix at 300 degrees F for 18 minutes, stirring and shaking the basket every 6 minutes to ensure even cooking.
Monitor closely as air fryer cooking times vary to prevent burning.
