Add the garlic, pine nuts and 2 tbsp. of oil to the food processor. Pulse a few times until minced. Scrape down the sides of the bowl.
Step 2
Add the basil leaves and another 2 tbsp. of oil. Pulse until finely chopped. Add the cheeses.
Step 3
With the machine running, slowly stream in the rest of the olive oil and blend until creamy. Scrape the pesto into a bowl.
Step 4
Taste, and adjust seasoning with salt (if needed). Stir in more olive oil to loosen the texture (if needed). It shouldn’t look like a thick glob.
Step 5
To store: transfer pesto to a small jar. Top with a layer of olive oil to prevent browning. Refrigerate until ready to use. It should last up to 1 week.
