Crunchy, seasoned Chex Mix with a savory, buttery coating is a family-favorite snack mix for parties and game day. This addictive, vegetarian munchie is easy to make in big batches.
Preheat oven to 250°F (120°C) and set out a large rimmed baking sheet.
In a very large mixing bowl, combine Corn Chex, Rice Chex, Wheat Chex, mini pretzels, cheese crackers, and roasted peanuts.
Melt unsalted butter in a small saucepan over low heat, then whisk in Worcestershire sauce, seasoned salt, garlic powder, and onion powder until fully blended.
Drizzle the melted butter mixture evenly over the dry mix in the bowl, tossing constantly with a spatula to ensure everything is evenly coated.
Spread mixture in an even layer onto the prepared baking sheet. Bake for 1 hour, stirring every 15 minutes to prevent hot spots and promote even crisping.
Remove from oven and let the Chex Mix cool completely on the baking sheet before serving or storing.
