Step 1

Put the parmesan cheese in the food processor and pulse until the cheese begins to look like small crumbs. Add the basil and parsley (if using), pine nuts, garlic, and salt and pepper to the food processor. Turn the food processor on medium setting until a green paste begins to form. Begin to drizzle the olive oil into the green paste while the food processor is on. Stop the food processor and use a rubber spatula to scrape any ingredients from the sides back down into the bowl. Pulse the food processor again until everything is incorporated. You can use immediately or freeze.

Step 2

Freezer instructions: If you are planning to freeze your pesto, pour it straight from your food processor into clean ice cube trays. Cover and put into the freezer. When pesto is completely frozen, transfer the pesto cubes from the ice trays to a labeled and dated freezer bag. Next time you need a quick dinner, grab a few cubes of pesto and let them thaw!
