Radish Greens Pesto Sauce
Radish Greens Pesto, a simple food waste recovery recipe using radish leaves in place of basil in pesto sauce. Easy, tasty, and so versatile!
Not sure what to do with radish greens? Make radish top pesto! We love switching up our pesto ingredients for a fun twist on the Italian classic, and reusing radish greens in pesto is a great way to reduce food waste.
Here’s why you should be using radish greens in pesto sauce:
- It’s tasty! First and foremost, radish greens are delicious in pestos and give a hearty, earthy flavor that compliments well with the cheese (or nutritional yeast), garlic, and salt in pesto sauce.
- It reduces food waste. Unfortunately, radish greens are often thrown out because people don’t realize they're edible, so this recipe save them from the compost (or worse, the trash can!).
- It’s super easy and very versatile. Simply blend the greens with nuts or seeds, cheese (or cheese alternative to keep it vegan), garlic, salt, and pepper and you have yourself a flavorful sauce that’s great on pizzas, vegetables, soups, and pastas.

🥣 How to make (step-by-step)
1️⃣ Step One: Wash and prep radish greens
First, wash the radish greens by cutting them from the stem and then soaking in a bowl of water.
Toss them around a bit to remove excess dirt, then remove them and lay then flat on a plate or kitchen towel or spin them in a salad spinner to dry. Then remove any remaining hard stems from the greens before making the pesto.
2️⃣ Step Two: Blend the greens, nuts or seeds, garlic, and oil
Next, add the cleaned dried radish tops to a blender. Add pine nuts — or sunflower or pumpkin seeds for a nut-free pesto — and garlic cloves and pulse until finely chopped.
As you’re pulsing the ingredients, drizzle in olive oil and continue to pulse until the chopped ingredients are well coated in oil but not completely smooth (the best pestos are a bit chunky).
3️⃣ Step Three: Add cheese, spices, and lemon juice to taste
The final step is to add parmesan cheese (we typically use vegan parmesan or nutritional yeast to keep it plant-based), salt, and pepper slowly, tasting and adding more until you reach your desired taste.
Pesto tip: Cheese and cheese alternatives are naturally salty, so go slow on the salt with pesto so you don’t overdo it (you can always add more, but not take any away!).
We finish off our pestos with a bit of lemon juice, but this is optional. Store the pesto in an airtight container in the fridge until ready to use!
💡 How to serve radish top pesto
Use this radish pesto in place of anything you typically enjoy with pesto. Some of our favorites are:
- On top of pizzas: Use pesto as a base instead of tomato sauce or olive oil.
- In soups: Stir a dollop of pesto into soups like our Carrot Greens Soup or White Bean Quinoa Soup.
- On roasted vegetables: We love drizzling a bit of pesto on top of simply roasted vegetables like Roasted Rainbow Cauliflower or Roasted Green Beans and Carrots.
- In pasta: Nothing is better than an easy pesto pasta, so replace the carrot greens with radish greens in this Carrot Top Pasta recipe.
❓ Recipe + radish greens questions
Radish greens are not toxic. The green leaves on radishes are edible and are in the same family as kale, cabbage, and brussels sprouts. Radish leaves can be cooked like any other leafy greens, such as sauteed, in soups, in salads, and in smoothies.
Radish leaves and stems are edible, however the stems can be tough so it’s best to trim the leaves from the stem before cooking and eating. Save the radish stems to use to flavor soup stocks like our food scrap vegetable broth.
Radish greens are a healthy leafy green that has 20 calories per serving and is a good source of vitamin C, vitamin K, and potassium (USDA Food Nutrient Database).
Pesto can be made vegan by omitting traditional parmesan cheese and instead using a dairy-free vegan cheese alternative, or nutritional yeast.
Pesto can be made nut-free by omitting the traditional pine nuts and substituting with seeds like sunflower seeds or pumpkin seeds.
♻️ Sustainable kitchen tips + tricks
This recipe is inherently a food waste recovery recipe, but here are a few tips and tricks for making this pesto even more sustainable.
Take advantage of radish season! Here in California radishes are in season all year round, however you can check where radishes are in season in your area using Seasonal Food Guide’s seasonality chart.
Use radish stem scraps. Don’t throw out the radish stem after cutting the leaves from the roots, instead radish scraps to flavor soup stocks. No vegetable goes to waste!
Make ahead to save time. Make a double or triple batch of this pesto and freeze for later to have a simple sauce for pasta or pizza when you’re low on dinner prep time in the future.
