This Pesto Sauce recipe with Walnuts is made without pine nuts, so, it's easy and more affordable! Y'all, this easy basil walnut pesto gets its vibrant green color that lasts and lasts from one simple trick and I'm sharing it with you!

Traditional Italian pesto recipes (Pesto di Basilico) is made with pine nuts, basil, garlic, Parmesan cheese and olive oil.
My homemade pesto sauce recipe skips the pine nuts and uses walnuts. You can make it with a more Southern twist and use toasted pecans! Walnuts and pecans are more readily available and cost less where I live, but you can use pine nuts if you prefer those.
There are so many ways to enjoy pesto! If you love pasta in green sauce, you've got to make this today! See even more serving suggestions below.
And did I mention it only takes 10 minutes, freezes well and is a pesto vegetarian recipe? You're welcome.
There's nothing better than having an easy creamy pesto sauce recipe readily available during the summer months when you have an abundance of basil available in your garden or at farmers markets!
Most grocery stores sell fresh basil in pots or "clam shell containers" in the produce section, so you can also make basil pesto year round!
Blanching basil for pesto
Here it is. My fail-proof trick for the best way to preserve fresh basil for making bright green pesto.

Substitutions & Variations
Trade "this" for "that" in this creamy pesto recipe.
- Use 1 large clove of garlic instead of the ½ teaspoon of garlic paste.
- Pine nuts can be substituted for walnuts. As a Southerner, I always have pecans on hand and often substitute them in this recipe.
- Basil itself has many different varieties such as chocolate basil, cinnamon basil, Thai basil, and more! Experiment with varieties you may grow or find at your local nursery or farmers market.
- Parsley and spinach can be added or even substituted for basil for a flavor variation.
How to use this pesto recipe with walnuts

- Use this walnut pesto recipe as a dipping sauce for your charcuterie board or crusty French bread.
- As a simple sauce for your favorite pasta dishes.
How to store
- To Store: Store any leftovers in the refrigerator, covered or in an air tight container. I like to pour a thin layer of additional oil on top of the pesto in the jar before putting on the lid.
- To Freeze: Pesto freezes well and can come in handy all year round. You can put the pesto in ice cube trays or muffin tins. Don't overfill. Let it sit in the freezer for a couple of hours and then pop each of the cubes out and put them in a freezer zip lock bag. You can freeze pesto for up to 6 months.

Equipment
Ingredients
- 2 cups firmly packed fresh basil leaves
- ¼ cup walnuts (lightly toasted)
- ¼ cup grated parmesan cheese
- ½ teaspoon garlic paste or 1 large clove garlic
- ½ teaspoon salt
- ⅛ teaspoon black pepper (optional)
- ⅓ to ½ cup olive oil or extra virgin olive oil
Instructions
- Prepare a small bowl of ice water. Bring a saucepan of water to boil.
- Add the basil leaves to the boiling water. Quickly remove the basil after 4 seconds with tongs or slotted spoon and plunge them into the bowl of ice water.
- This step is called blanching. Do not skip it! It’s a game changer for keeping the pesto green and not turning brown!
- Drain the blanched basil and pat dry with paper towels.
- In a food processor or blender, process the walnuts and cheese until ground. Add the blanched basil, salt and (if using) black pepper. Process until all the ingredients are blended.
- You can add the oil all at once and process until blended, scraping down sides, but I like to add it through the food chute so it doesn’t slosh the oil around. It creates a smoother mixture this way. (Start with ⅓ cup oil and add more if you want it thinner.)
- I think it also incorporates the oil better this way and I can decide if I want to add more oil if it isn’t creamy enough for me since packed basil leaves may vary. You still have to scrape down the sides about halfway into pouring the oil.
- Store the pesto in the refrigerator in a container with a tight lid.
Notes
- You can use 1 large clove of garlic instead of the ½ teaspoon of garlic paste.
- Pine nuts can be substituted for walnuts. As a Southerner, I always have pecans on hand and often substitute them in this recipe.
- Basil itself has many different varieties such as chocolate basil, cinnamon basil, Thai basil, and more! Experiment with varieties you may grow or find at your local nursery or farmers market.
- Parsley and spinach can be added or even substituted for basil for a flavor variation.
- Blanching basil only takes a few seconds and is a game changer. You'll thank me when your pesto is still bright green when you use it again and again.
