Preparation
Preheat your oven to 350°F / 175°C and line a baking sheet with parchment paper.
In a medium bowl, thoroughly mix the softened butter and grated Parmesan cheese.
Fold in the chopped walnuts.
Drop tablespoon-sized mounds of the mixture onto the prepared baking sheet, spacing them about 2 inches apart.
Sprinkle the fresh thyme and rosemary over each mound.
Bake for 8-10 minutes, or until the edges are golden brown and crispy.
Allow the crisps to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
Add a pinch of cayenne pepper or smoked paprika to the cheese mixture for a spicy kick.
