Pesto Recipe With Carrot Tops: Zero-Waste Herb Sauce With Bright Flavor

I developed this zero-waste pesto to transform carrot tops into a bright, herbaceous sauce that rivals traditional basil versions.

This vegan recipe requires just a blender and basic ingredients, creating a versatile condiment perfect for pasta, sandwiches, or dips.

Ingredients for Pesto Recipe with Carrot Tops

Transform carrot tops into a vibrant, herbaceous sauce with these simple plant-based ingredients.

The carrot tops are the star here—ensure they are fresh and brightly colored for maximum flavor. Farmers markets often bundle these for free with carrot purchases. Organic produce tends to yield more robust greens. For nuts, Trader Joe’s and Costco offer high-quality walnuts at reasonable prices. Nutritional yeast, essential for that cheesy note, is best found in bulk bins or Bragg brand at health food stores.

No carrot tops? Spinach or parsley can substitute in a pinch, though the flavor profile will differ. Walnuts can be replaced with cashews or almonds—all work beautifully. Pine nuts are traditional but less budget-friendly. For a nut-free version, sunflower seeds add richness without allergens. The olive oil must be extra-virgin for the best results.

This pesto keeps for 5 days in the fridge with a thin oil layer on top to prevent browning. For longer storage, freeze in ice cube trays for up to 3 months. Portion before freezing for easy use in sauces or dressings.

Step-by-Step Instructions for Pesto With Carrot Tops

This method ensures a smooth, vibrant sauce with balanced flavor and perfect texture.

Step 1: Toast the Walnuts for Depth

Heat a dry skillet over medium heat. Add the 0.5 cup Raw Walnuts and toast for 3-5 minutes, stirring frequently, until they’re golden brown and fragrant. Watch closely—nuts burn quickly once they start browning.

Toasting enhances their natural oils and adds a rich, nutty depth to your sauce. Remove from heat and let cool completely before blending. This prevents the nuts from steaming in the food processor, which would make your pesto oily rather than creamy.

Step 2: Pulse Aromatics and Greens

In a food processor, combine the 2 cloves Garlic Cloves, 2 cups Carrot Tops, and 0.5 cup Fresh Basil Leaves. Pulse in 1-second bursts about 10-12 times until finely chopped but not puréed. Stop to scrape down the sides as needed.

The carrot tops bring an earthy, slightly bitter note that pairs beautifully with the basil’s sweetness. This pulsing technique gives you control over the texture—you want small, uniform pieces without turning the greens into a paste before adding the other ingredients.

Step 3: Incorporate Remaining Dry Ingredients

Add the toasted walnuts, 0.25 cup Nutritional Yeast, 0.5 tsp Sea Salt, and 0.25 tsp Black Pepper to the food processor. Pulse again for 8-10 one-second bursts until the mixture resembles coarse sand.

The nutritional yeast contributes a subtle cheesy flavor and helps thicken the sauce naturally. At this stage, the mixture should look dry and crumbly—this is exactly what you want before introducing the liquid ingredients to create the perfect emulsion.

Step 4: Emulsify with Oil and Acid

With the food processor running continuously, slowly drizzle in the 0.75 cup Extra-Virgin Olive Oil through the feed tube. Process for 30-45 seconds until the mixture is smooth and creamy, stopping to scrape down the sides once or twice.

Then add the 2 tbsp Lemon Juice and pulse 3-4 times to incorporate. The acid brightens all the flavors and helps preserve the pesto’s vibrant green color. The final texture should be thick but pourable, with a glossy finish.

Step 5: Adjust and Rest

Taste and adjust seasoning if needed—though the salt should be balanced from the initial measurement. Transfer to a jar or bowl and let sit at room temperature for 10-15 minutes before serving. This resting period allows the flavors to meld together.

The pesto will thicken slightly as it rests. For the best texture, stir in a tablespoon of pasta water or warm water if needed before tossing with hot pasta or using as a spread.

Serving Suggestions for pesto recipe with carrot tops

Pasta Perfection

Toss 1 lb cooked pasta with ½ cup of this pesto while it’s still hot. Add ¼ cup reserved pasta water to create a silky sauce that clings beautifully. I love it with farfalle or penne for maximum surface area.

Sandwich Spread

Use as a spread for grilled cheese or veggie sandwiches—about 2 tbsp per sandwich is perfect. The walnuts add a satisfying crunch. Try it with roasted red peppers and fresh mozzarella on ciabatta.

Dip or Appetizer

Thin with 1-2 tbsp water or olive oil for a dip. Serve with crudités, pita chips, or as a topping for bruschetta. The bright flavor pairs wonderfully with cucumber slices and cherry tomatoes. 🥗

Protein Pairings

Drizzle over grilled chicken, baked salmon, or tofu for an herby finish. I especially love it on seared scallops—the nutty notes complement the sweetness beautifully.

Soup Enhancer

Stir 1-2 tbsp into minestrone or tomato soup before serving. It adds freshness that brightens up the whole bowl. Works equally well in creamy soups like butternut squash. 💡

Breakfast Boost

Swirl into scrambled eggs or spread on avocado toast. A 1 tbsp dollop on ricotta toast with flaky salt is my go-to weekend breakfast. The lemon notes wake up the whole dish.
