Homemade Pesto Recipe

This homemade pesto comes together in minutes and is one of the easiest ways to make the most of summer basil. Toss it with pasta, spread it on sandwiches, spoon it over grilled meats and vegetables, or swirl it into soups.
Pesto, or pesto alla Genovese, is a vibrant, garlicky green sauce from Genoa, Italy. Made with fresh basil, nuts, garlic, Parmigiano-Reggiano, and olive oil, it’s one of the easiest and most versatile sauces you can make at home. While pesto is traditionally made with a mortar and pestle, a food processor makes quick work of it.
This homemade pesto recipe uses walnuts instead of the traditional pine nuts, making it more affordable without sacrificing flavor. Once everything is blended together, you’d be hard-pressed to tell the difference. I make a batch whenever basil is overflowing in the garden, and since it freezes beautifully, I always stash a few containers away for quick meals later on.

What You’ll Need To Make Pesto Sauce
- Walnuts: Traditional pesto is made with pine nuts, but I almost always reach for walnuts. They’re easier to find, much less expensive, and have a rich, buttery flavor that works beautifully.
Almonds, pecans, and pistachios work well too. Pro tip: Toast the nuts in the oven or a dry skillet for a few minutes to deepen their flavor. - Garlic Cloves: Bring bold, punchy flavor that is key to the flavor of pesto.
- Fresh Basil Leaves: Use vibrant, fragrant leaves with no dark spots. Be sure to wash and dry them thoroughly—wet basil can dilute the pesto and dull the flavor.
- Extra Virgin Olive Oil: Binds everything together and adds smooth, fruity richness. Use one you enjoy the flavor of since it’s a major component of the sauce.
- Grated Parmigiano-Reggiano: Adds salty, nutty flavor. Always use authentic Parmigiano-Reggiano from Italy—look for the name stamped on the rind or clearly labeled on pre-grated packages. Avoid shelf-stable grated cheese or anything labeled “Parmesan” or “Parmesan cheese.”

Step-by-Step Instructions
Pulse the walnuts and garlic first, then add the basil and seasonings. As you slowly drizzle in the olive oil, the pesto will come together into a smooth, vibrant green sauce. Taking your time with the oil helps it emulsify for the best texture.
Pro Tip: If you don’t have a food processor, a blender works too, though you may need to stop and scrape down the sides a few times to keep everything moving.
Add the cheese and blend just until incorporated. It’ll thicken the pesto slightly and give it a rich, creamy texture.
How To Store & Freeze Pesto
Pesto keeps well in the refrigerator for about a week. To help prevent browning, smooth the surface and pour a thin layer of olive oil over the top before refrigerating (this seals out the air and prevents the sauce from oxidizing).
For longer storage, freeze pesto in ice cube trays. Once frozen, transfer the cubes to a freezer bag so you can thaw exactly as much as you need.
Best Ways to Use Homemade Pesto
Homemade pesto is far more versatile than just pasta. Here are some of my favorite ways to use it:
- Toss it with homemade pasta to make pesto pasta
- Make zucchini noodles
- Spoon over grilled chicken, shrimp, salmon, or steak
- Spread on focaccia, sandwiches and smash burgers
- Drizzle over roasted vegetables
- Stir into minestrone or vegetable soup
- Spread on pizza instead of tomato sauce
- Swirl into scrambled eggs or omelettes
- Mix into mayonnaise for sandwiches
- Spoon onto burrata with fresh tomatoes
- Drizzle over baked potatoes

Homemade Pesto Recipe
Ingredients
- ⅓ cup walnuts, toasted if desired (see note)
- 2 large cloves garlic, roughly chopped
- 2 cups packed fresh basil leaves
- ½ teaspoon salt
- ¼ teaspoon freshly ground black pepper
- ⅔ cup extra-virgin olive oil
- ½ cup grated Parmigiano-Reggiano
Instructions
- Place the walnuts and garlic in the bowl of a food processor fitted with a steel blade. Process until coarsely chopped, about 10 seconds. Add the basil leaves, salt, and pepper and process until mixture resembles a paste, about 1 minute. With the processor running, slowly pour the olive oil through the feed tube and process until the pesto is thoroughly blended. Add the Parmesan and process a minute more. Use pesto immediately or store in a tightly sealed jar or air-tight plastic container, covered with a thin layer of olive oil (this seals out the air and prevents the pesto from oxidizing, which would turn it an unappetizing brown color). It will keep in the refrigerator for about a week.
Notes
- Toasting the walnuts isn't essential, but it brings out their flavor. To toast them, preheat the oven to 350°F. Arrange the walnuts on a baking sheet in a single layer. Bake, checking frequently, until lightly toasted and fragrant, 6 to 8 minutes. Transfer immediately to a plate to cool.
- Freezing Instructions: Pesto can be frozen in an airtight container for up to 6 months. You can also divide your prepared pesto into the compartments of an ice cube tray and freeze. Once it’s frozen, remove the pesto cubes from the tray and put in a sealable plastic bag or an airtight container. You can add the defrosted pesto cubes to soups, pasta dishes, eggs, sandwiches, and potatoes.

I doubled this recipe and came out not thick enough. Flavor not tested yet, but something in the quantities not right when doubled.
Hi Peg, sorry you had a problem with doubling this. Is there any chance you could have made a measuring error?
I made this and it was so amazingly good. I keep it in a small mason jar in the fridge and its ready anytime for a quick stir into pasta, veggies, a dallop in my power bowl, or just a little extra seasoning in sauces or as a condiment on sandwiches. Makes me want to try versions of pesto with maybe sundried tomatoes instead of basil, or roasted peppers. I love this!
I generally feel like all pesto recipes are generally the same. Pesto is pesto after all. But this recipe is diffeeent. I can’t quite put my finger in it but every time I bring this pesto to a potluck, I get compliments on it. It also freezes well with a little extra oil and doesn’t turn brown/oxidize, so bonus points for that!
I have been meaning to write this review all summer, each time I make this pesto. I had never made pesto before and this recipe is both simple and delicious! It takes minutes to throw together and tastes wonderful on pasta and chicken. Thanks for another keeper!!
I’ve been making Basil Pesto for years, BUT this recipe makes the very BEST Pesto. I love it on my breakfast sandwich of English muffin, pesto, scrambled egg and roasted bell pepper.
This recipe is how I discovered once upon a chef! It’s my go to pesto recipe. I like the tip about freezing the pesto without adding the cheese. I keep half in the refrigerator and half in the freezer and it never turns brown.
Made this last night to throw on some pasta (I did farfalle with tomatoes and chicken). My husband told me it’s the best thing I’ve ever made. So easy and delicious!
PERFECT!! The ONLY thing I changed was the times it took to process….was much quicker than stated. Used my fresh basil from the garden and can’t get over how delicious this is. I even finger swiped the food processor bowl 😀 THANKYOU
The bitterness some people have experienced is the garlic. I’ve made this with sharp garlic and milder garlic. My first time screamed “bitter,” but I knew at once what happened. I bought fresher garlic.
Delicious. I add just a dash of lemon for some freshness.
