If you do not have a roasting pan, line a large baking sheet with parchment paper. If you have a large metal roasting pan, no need to line with parchment paper.
Mix all of your snack items – cereal, pretzels, rye chips, and bagel chips in a large bowl.
Combine melted butter, Worcestershire sauce, garlic powder, and seasoned salt in a bowl until well combined.
Add butter mixture to the cereal mixture, a little bit at a time, stirring it in to evenly combine.
Pour coated cereal in large roasting pan or on the parchment lined baking sheet. Shake quickly to let cereal mixture settle into a layer.
Bake in oven for 1 hour, stirring the mixture every 15 minutes. If mixture is still soggy after 1 hour, add 15 more minutes.
Remove from oven, remove from pan and cool on the piece of parchment paper. If using a roasting pan, lay out on pieces of paper towels or parchment paper to cool for 15 minutes.
Enjoy immediately or up to four weeks, stored in an airtight container.
Pour a little bit of a seasoning into the mixture at a time, stir, then pour some more. This will help coat all of the cereal mixture without one portion ending up soggy and over flavored.Substitute other snack items if there are things you may not like, just make sure to keep measurements (e.g., 1 cup of Cheerios for 1 cup of the Chex) the same. If you add in other things rather than substituting them, the seasoning measurements will be off.Get the smallest pretzels you can find since they’re the biggest part of this snack mix. The smaller the pretzel, the better they fit into this mix.Break up the bagel and rye chips it small pieces so they go further in the snack mix and you get some in almost every bite.
