Keto Pesto Sauce Recipe

Keto Pesto Sauce


  • 2 cups fresh basil leaves, packed
  • 1/2 cup grated Parmesan cheese
  • 1/2 cup pine nuts or walnuts
  • 3 cloves garlic, peeled
  • 1 cup extra-virgin olive oil
  • Salt and black pepper to taste
  • 1/2 cup grated Pecorino Romano cheese (optional)


Prepare the Ingredients:

  1. Wash and Dry Basil:
    • Wash the fresh basil leaves thoroughly and pat them dry with paper towels.
  2. Grate Cheeses:
    • Grate the Parmesan and Pecorino Romano cheeses if not pre-grated.

Make the Keto Pesto Sauce:

  1. Toast Nuts:
    • In a dry skillet over medium heat, toast the pine nuts or walnuts for 2-3 minutes until they become lightly golden. Be cautious not to burn them.
  2. Combine Ingredients:
    • In a food processor, combine the fresh basil leaves, toasted nuts, grated Parmesan cheese, and peeled garlic cloves.
  3. Pulse Until Coarse:
    • Pulse the ingredients in the food processor until they are coarsely chopped.
  4. Drizzle in Olive Oil:
    • With the food processor running, gradually drizzle in the extra-virgin olive oil. Continue processing until the mixture forms a smooth paste.
  5. Season:
    • Season the Keto Pesto Sauce with salt and black pepper to taste. Blend again to ensure even seasoning.
  6. Add Pecorino Romano (Optional):
    • If using Pecorino Romano cheese, add it to the food processor and pulse until combined. This step is optional and adds an extra layer of flavor.

Adjust Consistency and Flavor:

  1. Adjust Thickness:
    • If the pesto is too thick, you can add more olive oil, a tablespoon at a time, until it reaches your desired consistency.
  2. Taste and Adjust:
    • Taste the pesto and adjust the salt, pepper, or other ingredients as needed to suit your preferences.

Serve or Store:

  1. Serve Immediately or Store:
    • Use the Keto Pesto Sauce immediately as a topping for zoodles (zucchini noodles), grilled meats, or as a dip. Alternatively, store it in an airtight container in the refrigerator.


  • Storage: Store the Keto Pesto Sauce in the refrigerator for up to 1 week. You can also freeze it in an ice cube tray for individual portions.
  • Customization: Feel free to customize the pesto by adding a squeeze of lemon juice or adjusting the ratio of Parmesan to Pecorino Romano for a different flavor profile.
