What Is Basil Pesto?
Pesto is a traditional Italian sauce that originated in Genoa, Italy. Classic Pesto alla Genovese is made with fresh basil, pine nuts, Parmesan cheese, garlic, olive oil, and salt blended into a flavorful sauce.
While the traditional recipe is wonderful, it’s also very adaptable. Different nuts, cheeses, and herbs can be used depending on what you have on hand.
Ingredients You’ll Need
- Fresh basil leaves
- Pine nuts
- Freshly grated Parmesan cheese
- Garlic
- Extra virgin olive oil
- Fine sea salt
- Freshly cracked black pepper (optional)
Ingredient Notes
Basil
Fresh basil is the heart of this recipe. Choose vibrant green leaves without black spots or wilting.
Tender stems are packed with flavor too, so feel free to blend them along with the leaves. Simply discard any thick, woody stems.
Italian Basil vs. Thai Basil
Traditional basil pesto is made with Italian sweet basil (Genovese basil). It has tender leaves with a sweet, mildly peppery flavor that creates the classic pesto we all know and love.
Thai basil has smaller, firmer leaves and a bold flavor with hints of licorice, anise, and spice.
Can you use Thai basil?
Absolutely! Just know that it creates a different flavor profile.
A Thai basil pesto is:
- More aromatic
- Slightly spicy
- Mildly sweet
- Has subtle licorice and anise notes
It’s delicious with noodles, rice bowls, grilled vegetables, tofu, and Asian-inspired dishes.
For the most authentic Italian pesto, stick with Italian basil. If you only have Thai basil, try using half Italian basil and half Thai basil for a balanced flavor.
Pine Nuts
Traditional pesto uses pine nuts, but they can be expensive.
Fortunately, several affordable substitutes work beautifully.
My favorites are:
- Pistachios
- Raw cashews
- Blanched almonds
All three create a creamy pesto while keeping the color bright.
Walnuts are another option, but they have a stronger earthy flavor and naturally produce a darker pesto.
Whatever nut you choose, lightly toast it first for the best flavor.
Parmesan Cheese
Freshly grated Parmesan adds richness and the signature savory flavor.
For the best results, grate it from a block instead of using pre-shredded cheese.
Vegetarian Note
Traditional Parmigiano Reggiano is made with animal rennet, so it isn’t considered vegetarian.
If you follow a vegetarian diet, look for Parmesan-style cheese made with microbial (vegetarian) rennet.
Some great U.S. options include:
- BelGioioso Vegetarian Parmesan
- 365 by Whole Foods Market Parmesan
- Organic Valley Vegetarian Parmesan
- Trader Joe’s Parmesan (always check the label)
Olive Oil
Since pesto isn’t cooked, use the best quality extra virgin olive oil you have.
The Secret to Bright Green Pesto
One simple step makes a huge difference.
- Blanch the basil leaves for 5–10 seconds in boiling water before immediately transferring them to ice water.
- Pat the leaves completely dry before blending.
- This deactivates the enzymes responsible for oxidation, helping the pesto stay bright green for much longer.
- It’s optional if you’re serving the pesto immediately but highly recommended if you’re refrigerating or freezing it.
Don’t Worry If Your Pesto Turns Brown
One of the most common questions I receive is:
“Has my pesto gone bad because it turned dark?”
Usually, no.
Fresh basil naturally oxidizes after it’s chopped or blended. Even professionally made pesto darkens over time.
As long as your pesto:
- smells fresh,
- has been refrigerated properly,
- and shows no signs of mold,
it’s perfectly safe to eat.
To slow oxidation:
- blanch the basil first,
- store pesto in an airtight container,
- cover the surface with a thin layer of olive oil.
How to Make Basil Pesto
- Toast the pine nuts until lightly golden.
- (Optional) Blanch the basil for 5–10 seconds, then transfer to an ice bath and pat dry.
- Add basil, garlic, and pine nuts to a food processor.
- Pulse until finely chopped.
- Add Parmesan.
- Slowly drizzle in the olive oil while blending.
- Blend until creamy but still slightly textured.
- Season with salt and pepper.
Vegan Basil Pesto
- Making this recipe vegan is easy.
- Replace the Parmesan with:
- ½ cup nutritional yeast (nooch).
- For an even creamier pesto, blend in 1–2 tablespoons of raw cashews.
- Taste and adjust the salt before serving.
Khushboo’s Tips
- Blanch basil before blending if you want vibrant green pesto that stores well.
- Don’t panic if your pesto darkens. Oxidation is natural and doesn’t mean it has spoiled.
- Use freshly grated Parmesan for the best flavor and texture.
- If you’re vegetarian, choose Parmesan made with microbial rennet.
- No pine nuts? Pistachios, raw cashews, and blanched almonds are excellent substitutes. Walnuts work too but create a darker pesto.
- Use good-quality extra virgin olive oil.
- Blend just until combined. Homemade pesto should have a little texture.
- Slowly drizzle in the olive oil while blending for a smooth, creamy consistency.
- Reserve a little pasta water when tossing pesto with pasta. It helps the sauce coat every strand beautifully.
- Store pesto with a thin layer of olive oil on top to reduce oxidation.
- To make it vegan, replace the Parmesan with nutritional yeast (nooch).
- Italian sweet basil gives the classic flavor. Thai basil creates a bolder pesto with subtle licorice notes.
- Blend in the tender basil stems for extra flavor and less waste.
Storage
Store pesto in a clean glass jar in the refrigerator for up to 5 days.
Cover the surface with a thin layer of olive oil before sealing.
Freezing instructions
Freeze pesto in:
- Ice cube trays
- Silicone molds
- In a freezer safe ziplock, flatten the pesto and freeze.
- Small airtight containers
Freeze for up to 3 months.
