Ingredients for Lemon Arugula Pesto
Not only does making homemade pesto come together quickly, but it also only requires a handful of ingredients. Because you only need a few ingredients make sure that you pick quality ingredients.

- Arugula – Arugula is a peppery, spicy, and slightly tart green in the same family as cabbage and mustard greens. Sometimes referred to as rocket, it can be served both raw and also cooked such as in pastas and soups.
- Basil – The natural sweetness and slight licorice flavor of the basil balances the peppery bite of the arugula.
- Lemon – Both the zest and the juice bring a brightness to this pesto. In addition, the acid in the juice helps the pesto stay bright green longer.
- Pistachios – While traditional pesto uses pine nuts, pistachios offer a slightly mellower, buttery flavor. Use roasted, unsalted pistachios if possible.
- Parmigiano-Reggiano – This not only brings salt to the pesto but also a layer of umami.
- Olive Oil – Pick a flavorful olive oil that you enjoy as it adds richness to the sauce.
- Salt/Pepper – Season how you like. Keep in mind that if you are adding this to other salted things, the finished dish could get too salty.
How to Make Lemon Arugula Pesto
Making pesto at home is easy. It’s all about a few simple steps and tips. Once you get it down you can have fun experimenting and adding your own favorite flavors.
- Mise en Place – Roughly chop your garlic and make sure that your arugula and basil is washed and dry. Zest your lemon and squeeze the juice.
- Pulse – Add the pistachios and garlic to your food processor and pulse until it is a sandy texture, about 15 seconds.

- Blend – Add the basil, arugula, lemon juice and zest, and a couple of ice cubes to the food processor. Puls until the mixture is finally chopped.
- Drizzle – With the food processor running slowly drizzle in your olive oil until you’ve reached your desired consistency. Add the Parmigiano-Reggiano and pulse a couple of times to combine.

- Store – Transfer your pesto to an airtight container. You can add a small layer of olive oil over the top if desired.
Variations and Substutions
The combination of basil and arugula gives that balance of peppery but sweet. However, you can make this same recipe with all arugula for a more predominate arugula flavor. In addition, you can swap out the cheese in this recipe for Pecorino-Romano. Like things spicy? Add some crushed red pepper flakes in at the end when you add the cheese.
How to Use Pesto
You can use this lemon basil pesto in the same way you would your favorite pesto recipes or store-bought pesto. Here are just a few ideas.
- Pasta – Toss your favorite pasta with this pesto. Don’t forget to add a little extra Parmigiano-Reggiano and some of that pasta water!
- Chicken – Chicken is delicious marinated in pesto. Add a little extra lemon to the marinade for more of a bright pop of flavor. This is the marinade I use for my Grilled Chicken Parmesan with Cherry Tomato Sauce.

- Vinaigrette – Add a tablespoon or two to your basic vinaigrette for an herbaceous pop of flavor.
- Caprese Salad – Drizzle this over your summer tomatoes and fresh mozzarella for a caprese salad with bold flavor.
- Shrimp – Toss shrimp in this pesto and skewer for a quick and easy grilled pesto shrimp recipe.
- Soup – Stir into soup just before serving. This would be a great addition to Tuscan White Bean Soup with Croutons.
- Potatoes – Toss warm roasted or boiled potatoes in this pesto for an instant burst of flavor. This is also delicious with grilled or roasted vegetables.
- Fish – Use this as a marinade or finishing sauce for fish such as salmon, sablefish, halibut, sea bass, or grouper.

Storage and How to Make Your Pesto Stay Green Longer
Have you ever wondered how to make your homemade pesto stay green longer? Oxidation is a natural process that happens with everything from avocados and apples to the arugula and basil in this lemon arugula pesto. However, it doesn’t affect the flavor of your pesto. If kept in an airtight container in the refrigerator it will last for a week. In addition, you can also freeze it and keep it for up to a month. Here are a few tips though for making its vibrant color last a little longer.
- Ice – Add an ice cube or two when blending your pesto. This shocks the herbs and locks in their color.
- Olive Oil – Drizzle olive oil over the top of your pesto. It creates a barrier slowing down the oxidation process.
- Acid – Squeeze lemon or lime over the top of your pesto depending on what you used. If your homemade pesto doesn’t call for any sort of acid use the olive oil method.
- Blanch – Briefly blanch your herbs in boiling water for ten seconds and then transfer them to an ice bath to shock them. Make sure they are thoroughly dried before making your pesto.
Tip From the Beach

Have you ever picked up a lemon at the grocery store and noticed it had an almost unnatural sheen to it? Many commercial citrus have a thin layer of wax on the outside. While it is totally safe to consume once washed, when it comes to purchasing citrus that you plan on zesting, always opt for organic when you can. Not only is this citrus free of the waxy coating, but it is also free of pesticides.
