Preheat oven to 250°F and melt butter in a small saucepan over low heat. Stir in Worcestershire sauce, garlic powder, onion powder, and paprika until smooth. Remove from heat.
6 tablespoons butter, 2 tablespoons worcestershire sauce, 1.5 teaspoons garlic powder, 1 teaspoon onion powder, 0.5 teaspoon paprika
Combine all Chex cereals, mixed nuts, and bagel chips or pretzels in a large mixing bowl. Pour melted butter mixture slowly over dry ingredients while stirring constantly with a spatula to coat evenly.
3 cups rice chex cereal, 3 cups corn chex cereal, 2 cups wheat chex cereal, 1 cup bagel chips or pretzels, 1.5 cups mixed nuts, 6 tablespoons butter, 2 tablespoons worcestershire sauce, 1.5 teaspoons garlic powder, 1 teaspoon onion powder, 0.5 teaspoon paprika
Spread coated mix in a thin layer on a rimmed baking sheet. Bake for 45 minutes, stirring every 15 minutes to redistribute coating and prevent clumping.
Check for light golden color and dry texture at 45 minutes. If pieces still feel damp, bake an additional 5-10 minutes, stirring once more.
Cool on the baking sheet for 30 minutes before transferring to storage. This sets the crisp texture and prevents softness.
