This is one of our base recipes. Classic basil pesto is delicious, but did you know that you can make pesto with any variety of greens? We love using basil in the summer when it’s in season, but come fall or winter, we like to use heartier greens such as kale and arugula. This easy pesto recipe is great on pasta, vegetables, and fish, and is a perfect sauce to make and keep on hand! Use this recipe as a guide, and then get creative customizing it to your taste!

Health Benefits of Homemade Pesto

Learning how to make pesto sauce from scratch is a great way to expand your culinary horizons! Pesto is a healthy sauce/dip/spread that can boost the nutritional quality and flavor of a dish. The featured health-promoting ingredients in this recipe are greens, nuts, and extra virgin olive oil.


Leafy greens are an important part of a healthy, balanced diet. They are rich in essential vitamins, minerals, and phytochemicals that promote health and help fight diseases. Blending leafy greens into a healthy pesto recipe is an easy way to incorporate them in your diet!


Nuts of all varieties contain plant-based protein, fiber, and healthy fats. These nutrients help you feel satisfied until your next meal.

Extra Virgin Olive Oil

Extra virgin olive oil is a key component of the Mediterranean Diet. It contains high amounts of heart-healthy monounsaturated fatty acids and polyphenols which may reduce inflammation. Additionally, certain nutrients require fat for absorption; using extra virgin olive oil in pesto can boost the nutritional quality of a dish (1, 2). 

Equipment Recommendations

Traditional pesto recipes used to be made with a mortar and pestle, but we realize that is probably not one of your essential kitchen utensils. Instead, we recommend using a food processor, like this basic Hamilton Beach Food Processor.

Can you make pesto in a blender? Sure! However, the size and type of blender will greatly impact the outcome. We recommend using something small, like a NutriBullet. An immersion blender with a measuring beaker will also do the job!

Make sure that you also have a silicone spatula on hand for scraping down the sides of the food processor/blender.

Culinary Tips for Making the Pesto Base Recipe

When measuring the greens, gently pack them into the cup, but don’t pack so much that the leaves fall out of the cup.

Depending on the size of your food processor or blender, you might need to double the recipe. The jar/bowl needs to be full of enough ingredients to properly blend.

Be careful with the amount of fresh garlic – it has strong flavor! It’s better to start with less, taste, and add more if needed.

Process until you reach your desired texture. For a smooth and creamy pesto sauce, process for longer.

Different pesto recipes may have slightly different ratios, but the ingredients will generally be the same: greens, olive oil, nuts, cheese, garlic, and salt.

Ingredient Substitutions

  • Greens: substitute any greens of your choice (spinach, arugula, kale, basil). Greens such as mustard greens, swiss chard, and beet greens have a stronger taste, so consider using a milder green, such as spinach, for half of the recipe. You can also add green herbs such as fresh dill, mint, parsley, or cilantro to enhance the flavor, but don’t use them as the only green; their taste is too strong. Choose herbs that compliment the other flavors in your dish.
  • Extra Virgin Olive Oil: substitute infused extra virgin olive oil or avocado oil. We don’t recommend using vegetable oil, as this is not a heart-healthy oil. If you want to enhance the pesto with a strongly flavored oil, such as walnut or truffle oil, use extra virgin olive oil as the base, then add the strong oil a little at a time, to taste. 
  • Cheese: use parmesan, Pecorino Romano, asiago, or aged cheddar. We think that cheese blocks taste best, but we also recognize the added convenience of pre-shredded cheese.
  • Nuts: you can make this pesto recipe without pine nuts by substituting walnuts, cashews, pecans, or almonds. We don’t recommend using peanuts in pesto, as they have a very distinct taste. 
  • Garlic: substitute ⅛ teaspoon garlic powder, ½ teaspoon garlic flakes, or ¼ teaspoon granulated garlic. 

Recipe Variations

To reduce the pungency of the garlic, roast it in the oven for a few minutes (keep the peel on).

For a more complex flavor, toast the nuts before adding them to the blender.

Add lemon zest and/or juice to brighten the flavor.

To make this pesto recipe vegan, leave out the cheese. To maintain some of the umami flavor, add 1 Tablespoon of nutritional yeast.

Serving Suggestions

Serve pesto on top of fish, tossed in with a grain-based salad, or mixed in with noodles to make pesto pasta. These are some of our favorite recipes with pesto, but feel free to use it in whatever sound great to you! 

Storage Recommendations

Pesto oxidizes in the refrigerator which turns the bright green color to olive green. This doesn’t necessarily affect the flavor – it just doesn’t look as pretty! To help preserve some of the color, drizzle extra virgin olive oil on top of the pesto before refrigerating. Alternatively, cover the pesto with plastic wrap and let it touch the surface so that it doesn’t have any contact with the air.

Pesto also freezes well. For easy use and thawing, freeze pesto in small servings (a silicone ice tray is great for this). When ready to eat, simply pop a cube or two out, thaw, and you’re ready to go!
