Ingredients You Need
There are just 5 main ingredients you'll need to make a traditional Italian pesto.
- Shelled, roasted pistachios: While it's tempting to buy pre-shelled pistachios, I've found that shelled pistachios (that you peel on your own) tend to have a more potent flavor.
- Basil leaves: Fresh summer basil is always going to be best!
- Parmesan cheese: Take the time to grate the cheese by hand. Trust me, it will be worth it for amazing flavor.
- Lemon: Both the peel and the juice are used for this recipe.
- Extra virgin olive oil: There's a decent amount of olive oil in the recipe, so make sure you're choosing a high-quality option, just like the Italians use.
How To Make This Recipe
This recipe is super quick and easy to make - in under 10 minutes!
1. Blend the pistachios in a food processor on high until finely chopped.
2. Add the basil, parmesan cheese, lemon peel, and lemon juice.
3. Slowly drizzle in olive oil while the processor runs on high speed until a paste consistency forms.
4. Taste and add pepper and salt to taste, as needed. Check the texture and add 1 tablespoon (14 grams) of water at a time until you reach your desired consistency.
Expert Tips
- I like to keep the pesto thicker if I’m using it as a sandwich spread or for pasta (since it will be thinned out with pasta water). However, if you’re using it as a garnish or sauce, you can make it a thinner consistency.
- If you use salted pistachios, you may not need to add additional salt. Always taste the pesto before adding additional seasoning.
- Don't be tempted to add more extra virgin olive oil than is called for in the recipe. Too much oil can dilute the flavor of the basil and other ingredients, along with making the pesto too oily. You're looking for a creamy consistency.
Recipe FAQs

When making Italian pesto, you're looking for a creamy but still slightly chunky consistency. You can use water to make the pesto thinner if you find that it's too thick.
