01 - Set oven to 300°F and line a baking sheet with parchment paper.
02 - In a small saucepan or microwave-safe bowl, melt unsalted butter. Stir in garlic powder or minced fresh garlic, parmesan cheese, chopped parsley, salt, black pepper, and red pepper flakes if desired.
03 - Place Ritz crackers in a large mixing bowl, pour the butter mixture over them, and gently toss to ensure even coating without breaking the crackers.
04 - Spread the coated crackers in a single, even layer onto the prepared baking sheet.
05 - Bake for 10 to 12 minutes until crackers are crisp and lightly golden, monitoring closely to prevent over-baking.
06 - Remove from oven and allow to cool slightly before serving. Store any leftovers in an airtight container.
