In a large crock pot or slow cooker, combine the crackers, pretzels, cereal and cashews.
In a small bowl, whisk together the melted butter, Worcestershire and ranch seasoning. Gradually pour over the snack mix, and stir well to coat the mix.
Turn the slow cooker on low heat and roast for 2 hours, stirring the mix every 30 minutes.
When mix is done roasting, spread the mix out evenly on a flat surface lined with waxed paper to cool completely. Sprinkle with the Parmesan cheese.
Cool completely before storing in an airtight container.
Oven Directions:Place coated mix on baking sheets, and roast at 250 degrees for 1 hour, 15 minutes. Stir the mix every 15 minutes so it toasts evenly. Cool as directed above. Add the Parmesan cheese once mix has cooled.
Notes
This recipe is ideal for use with a larger slow cooker, due to the volume of ingredients. If you have a smaller slow cooker, oven use is recommend instead.Make sure you let the snack mix cool completely before placing in storage containers. Cooling will allow the mix to crisp up and dry completely, letting out any heat or steam from the roasting process.
