Place sourdough (4 slices/approx 150g) and rosemary leaves (1 tbsp) into a food processor and process into crumbs.
Heat olive oil (1 tbsp) and butter (1 tbsp) together in a frypan until sizzling, then add crumb mixture to pan.
Mix to coat crumbs in oil and butter, and fry over medium high heat, stirring until crumbs are browned and crisp.
Add crushed garlic (1 clove) to breadcrumb mixture and mix well to combine thoroughly. Continue to fry for 1-2 minutes then remove from heat.
Serve sprinkled over pasta.
Notes
The pangrattato will get a little more crisp on standing.
You could substitute fresh thyme leaves for the rosemary, depending on your taste or what dish you are serving the pangrattato with.
You don't need to limit yourself to sprinkling these crumbs over pasta, they would also be great over a rich, thick casserole or on top of mashed potatoes or risotto.
