This ultra-crispy Chex mix gets a gourmet upgrade with nutty brown butter, Worcestershire, and a shower of cheddar cheese powder for bold, cheesy flavor. Perfect for parties, game day, or gifting.
Preheat oven to 250°F. Line a large rimmed baking sheet or use a large roasting pan.
In a very large bowl or roasting pan, combine Rice Chex, Corn Chex, Wheat Chex, pretzels, cheese crackers, and mixed nuts.
Brown the butter: Add butter to a medium saucepan over medium heat. Cook, stirring, until it foams, then the milk solids turn deep golden and smell nutty, 4 to 6 minutes. Remove from heat.
While the butter is hot, whisk in Worcestershire sauce, brown sugar, seasoned salt, garlic powder, onion powder, and cayenne.
Drizzle the brown butter seasoning evenly over the cereal mixture, tossing constantly to coat every piece.
Spread the mix in an even layer. Bake for 60 minutes, stirring every 15 minutes for even toasting.
Immediately after removing from the oven, sprinkle cheddar cheese powder over the hot mix and toss until evenly coated. Add dried parsley if using.
Cool completely on the pan until crisp. Transfer to an airtight container.
Serve or store at room temperature for up to 1 week.
Notes
For extra cheesiness, add another 0.25 cup cheese powder, but season salt more lightly to avoid over-salting. If sensitive to heat, skip the cayenne. This mix also works well with bagel chips or more nuts—keep total dry volume around 12 to 14 cups for best coating.
