Parmesan-Thyme Crackers

This recipe is from Barefoot Contessa: Back to Basics. The crackers are perfect as an appetizer, and the variations are endless.
1/2 cup butter, softened
1 cup grated Parmesan cheese
1 1/4 cups all-purpose flour
1/2 tsp. salt
1/2 tsp. black pepper

1 tsp. chopped fresh thyme

1. Beat butter with an electric mixer until fluffy. Beat in Parmesan cheese and remaining ingredients.
Remove dough from bowl, and roll into a log; wrap in plastic wrap, and chill for 30 minutes.

2. Slice the log into thin disks, and place on a parchment paper-lined baking sheet.

3. Bake at 350° for 15 to 18 minutes. Remove from pan, and cool completely on a wire rack. Store in an airtight container.

Blue Cheese-Pecan-Rosemary Crackers: Replace the Parm with 3/4 cup blue cheese; substitute chopped fresh rosemary for the thyme; and add in 1/2 cup toasted chopped pecans and 1 tsp. grated lemon zest.
