Preheat your oven to 300°F (150°C) and line a baking sheet with parchment paper.

Melt the unsalted butter in a small saucepan, then stir in garlic powder, onion powder, dried parsley, sea salt, and black pepper.

Incorporate Parmesan cheese and cheddar cheese into the butter mixture, mixing until fully combined.

Pour the cheese mixture over the Ritz Bits crackers in a large mixing bowl and gently toss to coat.

Spread the coated Ritz Bits in a single layer on the prepared baking sheet and bake for 15-20 minutes, stirring halfway through.

Let the snacks cool completely before serving or storing.

Store leftovers in an airtight container at room temperature for up to 3-5 days.
