I absolutely love discovering new ways to use every part of fresh produce, and this Celery Leaf Pesto Recipe is one of those delightful surprises that quickly became a staple in my kitchen. It’s vibrant, fresh, and packed with flavor, turning the often-overlooked celery leaves into a luscious, versatile sauce. Whether I’m stirring it into pasta, spreading it on crusty bread, or adding a punch of green to roasted vegetables, this pesto never fails to brighten my meals and impress my guests.
Why You’ll Love This Celery Leaf Pesto Recipe
What really excites me about this Celery Leaf Pesto Recipe is its bright, herbaceous flavor that feels both familiar and wonderfully unique. The celery leaves bring a fresh, slightly peppery note, perfectly balanced by the nutty richness of toasted cashews and the savory depth of Parmesan. The garlic and a squeeze of lemon juice add that perfect zing that makes every bite sing. It’s a vibrant pesto that’s less heavy than traditional basil versions but just as satisfying.
Another reason I adore this recipe is how easy it is to whip up. If you have a food processor, you’re only minutes away from a batch of this green goodness. It doesn’t require cooking, so it’s a brilliant option for quick weeknight dinners or last-minute entertaining. Plus, it feels so special and gourmet, yet it uses simple ingredients that you probably already have on hand. I love serving it at casual gatherings or slipping it into my weekday meals for an instant flavor boost.
Ingredients You’ll Need
To make this Celery Leaf Pesto Recipe, you’ll need just a handful of simple ingredients—all of which contribute to its fresh taste, creamy texture, and lovely green color.
- Celery leaves (4 cups lightly packed): These provide the fresh, aromatic base that gives the pesto its distinct flavor.
- Garlic cloves (2): Adds a pungent, warming kick that balances the brightness.
- Parmesan cheese (½ cup finely grated): Delivers a salty, umami richness to the sauce.
- Toasted unsalted cashews (¼ cup): Brings creaminess and a subtle nutty depth with a smooth texture.
- Lemon juice (2 teaspoons): Adds the perfect touch of acidity to brighten everything up.
- Light extra virgin olive oil (⅓ cup): Helps emulsify the ingredients and give the pesto its silky finish.
Directions
Step 1: Start by washing the celery leaves thoroughly to remove any dirt or grit. I like to use a salad spinner to dry them well, as excess water can water down the pesto’s flavor and texture.
Step 2: Place the celery leaves, peeled garlic cloves, finely grated Parmesan, toasted cashews, and lemon juice into the bowl of your food processor. Pulse on low speed until the mixture is finely chopped but not pureed. You want some texture to remain for a lovely, rustic feel.
Step 3: With the processor still running on low, slowly drizzle in the olive oil in a steady stream. This helps the oil emulsify, creating a smooth, cohesive sauce. Stop once the pesto reaches your desired consistency—some like it chunkier, others smoother.
Step 4: If you’re not using the pesto immediately, transfer it to a preserve jar or airtight container. Pour a thin layer of olive oil on top to seal it and store it in the refrigerator. It will stay fresh for 4 to 5 days, though I rarely see it last that long in my house!
Servings and Timing
This Celery Leaf Pesto Recipe makes about 8 servings, which is perfect for a family dinner or to use as a flavorful addition over several meals. Preparation takes roughly 10 minutes from start to finish, with no actual cooking time involved, making it a brilliant option when you want something quick yet impressive. There’s no resting or cooling time needed either, so you can enjoy it immediately or store it for later.
How to Serve This Celery Leaf Pesto Recipe
From my experience, this pesto is incredibly versatile and delicious in many ways. My favorite way to serve it is gently tossing it with freshly cooked pasta for a quick meal that tastes far from ordinary. It also makes an excellent spread on toasted baguettes or rustic crackers—perfect for casual appetizers or snack time. I’ve even spooned it over grilled chicken or fish for an extra burst of flavor that elevates the entire dish.
When it comes to garnishing, I like to sprinkle some extra toasted cashews or a few shavings of Parmesan on top to add texture and visual appeal. A few whole celery leaves or a light drizzle of olive oil finish it beautifully on the plate. Serving the pesto at room temperature lets the flavors shine the most, but it also tastes wonderful chilled if you’re making it ahead of time.
As for beverages, I often pair this pesto with a crisp white wine like Sauvignon Blanc or a refreshing sparkling water with lemon, which complements the fresh herbal notes nicely. It’s perfect for weeknight dinners with the family, informal gatherings with friends, or even holiday meals where you want to add a fresh sidekick to the usual spread.
Variations
One of the things I love about this Celery Leaf Pesto Recipe is how adaptable it is to different tastes and dietary needs. If you want a nut-free version, try swapping the toasted cashews for toasted sunflower seeds or pumpkin seeds—they add a similar creaminess without nuts. For a vegan version, simply replace the Parmesan with a nutritional yeast alternative or vegan cheese to keep that cheesy umami quality.
If you’re craving a flavor twist, try adding fresh herbs like parsley, basil, or mint to the celery leaves for a different green profile. Adding a pinch of chili flakes gives the pesto a little spicy kick that I find irresistible. You can also experiment by lightly roasting the celery leaves or garlic beforehand to introduce a smoky depth, though I personally enjoy the fresh brightness best.
As for technique, if you don’t have a food processor, a powerful blender works too, but be careful not to overblend. You can also make a chunkier pesto by chopping everything finely with a knife and whisking in the olive oil gradually by hand for a more rustic finish. It’s really about what feels best for your kitchen style.
Storage and Reheating
Storing Leftovers
If I have leftover pesto, I always store it in a small glass jar with a tight lid. It’s important to add a thin layer of olive oil on the surface to prevent oxidation and browning. Kept in the refrigerator, the pesto stays fresh and vibrant for up to 4 or 5 days. I try to use it quickly because the fresh herb flavor is at its peak during this time.
Freezing
This pesto freezes beautifully, which I find super handy. To freeze, I spoon it into ice cube trays for easy portioning. Once frozen solid, I pop the cubes into a freezer-safe bag or container. This way, I can thaw just what I need for a single meal without waste. Frozen pesto retains great flavor and can keep in the freezer for up to 3 months. Just thaw it overnight in the fridge.
Reheating
When it comes to reheating, this pesto is best warmed gently or brought to room temperature rather than microwaved aggressively. I usually stir it into warm pasta or reheat it slowly on the stovetop with a splash of olive oil. Avoid high heat to preserve the fresh herbal notes and prevent the sauce from turning bitter. If you’ve frozen it, give it a good stir after thawing to reincorporate any separated oils.
FAQs
Can I use celery stalks instead of celery leaves for this pesto?
Celery stalks have a very different texture and more fibrous quality than leaves, so they’re not ideal for this recipe. The leaves offer the bright, tender herbal flavor that makes this pesto unique. However, you could try using a small amount of chopped celery stalk along with other herbs if you want a twist, but I wouldn’t substitute them entirely.
Is this pesto gluten-free?
Yes, this Celery Leaf Pesto Recipe is naturally gluten-free, as it contains no wheat or gluten-containing ingredients. Just be sure your Parmesan cheese and other packaged ingredients are certified gluten-free if you have a sensitivity.
Can I make this pesto without cheese to keep it vegan?
Absolutely! You can simply omit the Parmesan cheese or replace it with nutritional yeast or a vegan cheese substitute. This change shifts the flavor slightly, but you’ll still get the creamy, tasty essence of the pesto.
What can I use instead of cashews if I have a nut allergy?
Toasted seeds like sunflower seeds or pumpkin seeds are wonderful nut-free alternatives that add creaminess and subtle flavor without allergens. You can toast them lightly before adding for extra depth.
How do I keep the pesto from turning brown quickly?
To keep your pesto vibrant green, store it in an airtight container with a thin layer of olive oil on top to prevent air from oxidizing the leaves. Refrigerate and consume it within 4-5 days for the best freshness and color.

I genuinely hope you give this Celery Leaf Pesto Recipe a try—it’s one of those unexpected little delights that turns ordinary ingredients into something special.
