Add the bread cubes, garlic and parsley to a food processor and blitz until you get a slightly coarse mixture.
Transfer to a nonstick pan and add the seasonings.
Add the butter and oil and cook this over low heat for about 10, stirring every few seconds.
Once the breadcrumbs start to get a light brown color, take the pan off heat and allow the mixture to cool down before storing.
Notes
To lend the Pangrattato a nice spicy kick, you can add some red pepper flakes or jalapeno flakes into the mix. I love using my jalapeno infused salt sometimes when I want the breadcrumb mixture to have a bit of spice.
Make sure you keep stirring the breadcrumb mixture continuously or you'll end up burning the bread. Also remember- no high heat!
Avoid overprocessing the bread. Leave it a little coarse and chunky- the contrast between the larger and fine crumbs is amazing!
To lend these a nice tangy flavor, I use some of my leftover oil from my homemade oven dried tomatoes to sauté the breadcrumbs.
