How to Make Carrot Top Pesto: A Flavorful, Zero-Waste Twist on Classic Pesto
Transform leftover carrot greens into a vibrant, aromatic pesto that maximizes flavor and minimizes food waste.
Carrot Top Pesto: Turning Greens Into Gold
For generations, carrot tops—those leafy green crowns attached to a bunch of carrots—have often found their way into the compost bin or been discarded as kitchen scraps. But these humble greens are not only edible, they’re brimming with flavor and nutrients, making them a brilliant, sustainable ingredient for vibrant, homemade pesto. Embracing carrot tops in your kitchen is a simple way to minimize food waste and expand your culinary repertoire with bold, herbal notes that rival classic basil pesto.
Why Make Carrot Top Pesto?
- Reduces Food Waste: Using every part of your produce honors both your food and your wallet.
- Packed with Flavor: Carrot greens lend a slightly earthy, fresh flavor akin to herbs like parsley or tarragon.
- Nutritional Value: Carrot tops are full of vitamins, minerals, and antioxidants.
- Recipe Flexibility: The pesto can be adapted to suit vegan, nut-free, or dairy-free diets.
- Versatile Uses: Carrot top pesto can be used for pasta, sandwiches, vegetables, and more.
What Are Carrot Tops and Are They Safe to Eat?
Carrot greens are the feathery leaves attached to the carrots you buy at farmers markets, through CSA shares, or fresh from your garden. Despite a common myth, they are not toxic for humans. In fact, they share a flavor profile with hardy greens like parsley, tarragon, or even delicate celery leaves. While the texture of the stems can be tough, the soft fronds lend themselves perfectly to sauces, soups, and especially pesto.
To prepare carrot tops safely:
- Separate the greens from the carrots as soon as you bring them home to prevent wilting.
- Wash thoroughly, as carrot tops often have sand and dirt trapped in their fronds. Submerge in a bowl of cold water, swish, and repeat until the water runs clear.
- Pat dry with a towel or use a salad spinner to remove excess moisture.
Classic Carrot Top Pesto Recipe
This bright green sauce is endlessly adaptable, but here’s a foundational recipe to start with:
| Ingredient | Amount |
|---|---|
| Carrot tops (leaves only, packed) | 2 cups |
| Fresh herbs (parsley, tarragon; optional) | 1/4 cup |
| Garlic cloves | 2 small |
| Toasted nuts (almonds, pine nuts, macadamia) | 1/3 cup |
| Lemon juice and zest | 1 lemon |
| Salt and pepper | To taste |
| Parmigiano Reggiano, grated | 1/2 cup |
| Extra-virgin olive oil | 5–6 tbsp |
Instructions
- Prepare Carrot Tops: Remove tough stems, soak greens in cold water, and dry thoroughly.
- Blend Ingredients: In a food processor, combine the carrot tops, optional herbs, garlic, nuts, lemon juice and zest, cheese, and seasonings. Pulse until finely chopped.
- Add Olive Oil: With the processor running, slowly stream in olive oil until the mixture emulsifies and starts to pull away from the sides.
- Taste and Adjust: Season with additional salt, pepper, lemon juice, or olive oil as desired.
- Store: Use immediately or transfer to an airtight container. Cover with a thin layer of oil for best freshness and store in the refrigerator up to 1 week or freeze for up to 6 months.
Ingredient Swaps and Recipe Variations
- Dairy-Free/Vegan: Replace Parmigiano Reggiano with nutritional yeast for a cheesy flavor.
- Nut-Free: Use seeds like sunflower or pumpkin seeds instead of nuts.
- Add Spice: Blend in chili flakes, cumin, cardamom, turmeric, or ginger for extra complexity.
- Herb Variation: Add or swap in basil, parsley, spinach, arugula, or cilantro for unique twists.
- No food processor? Use a blender or chop everything very finely by hand and mix with oil.

- Use only the tender leaves: Discard tough or woody stems; they can be too fibrous for pesto but are great in homemade stocks.
- Toast your nuts: Lightly toasting nuts (or seeds) before processing intensifies their flavor and aroma.
- Balance flavors: Taste as you go. Carrot tops can be slightly bitter, so add a little extra lemon juice or cheese if needed.
