Step 1
Preheat oven to 300°F (150°C). Line a large, rimmed baking sheet with parchment paper.

Step 2
Melt 1/2 cup butter. Stir in garlic powder, onion powder, parsley flakes, sea salt, black pepper, and optional smoked paprika & cayenne pepper until well combined.

Step 3
Add Parmesan and sharp cheddar cheeses to the seasoned butter mixture; stir well.

Step 4
Pour the seasoned cheesy butter mixture over Ritz Bits in a very large bowl. Gently toss until all crackers are evenly coated.

Step 5
Spread coated Ritz Bits in a single layer on the prepared baking sheet. Bake for 15-20 minutes at 300°F (150°C), stirring gently halfway through. Crackers should be lightly golden and cheese melted. If still soft, bake another 3-5 minutes, watching closely.

Step 6
Remove from oven and let cool completely on the baking sheet for maximum crispiness. Gently break apart any stuck clusters and transfer to a serving bowl. Serve as a party appetizer, movie night snack, or garnish for soups and salads.

Step 7
Store any leftovers in an airtight container at room temperature for up to 3-5 days.
