The original Chex party mix recipe calls for 3 cups each of corn, rice and wheat Chex cereal and a cup each of mixed nuts, bite-size pretzels and garlic flavor bite-size bagel chips. Also gather butter, Worcestershire sauce, seasoned salt, garlic powder and onion powder.
Take a large bowl and mix the cereals, pretzels, nuts and bagel chips, and then set aside. In a smaller bowl, melt 6 tablespoons of butter in the microwave. Stir in 2 tablespoons of Worcestershire sauce, 3/4 teaspoon of garlic powder, 1 1/2 teaspoons of seasoned salt at 1/2 teaspoon of onion powder. Pour the butter mixture over the cereal and stir until it is all coated. Microwave the mixture in the microwave on high for 5 to 6 minutes, stirring every two minutes. To cool, spread on paper towels, and then store the mix in an airtight container.
One way to modify the recipe includes using a custom mix of Chex cereal by combining or eliminating any flavor. As long as there are 9 cups of cereal in the mix, the recipe works. It is also possible to make the recipe healthier by substituting the butter for 3 tablespoons of margarine, using fat-free bagel chips or omitting the mixed nuts.
