Zero Waste Cooking

Did you know we waste 1/3 of the food we make? Watch this video to learn about why that's important. Then grab a parent and make this recipe that uses the entire carrot. There's no need to throw out the top!

Activity Instructions

for Observers (Pre-K through 2nd Grade) and Explorers (3rd Grade through 5th Grade)


c/o Epicurious 


Makes 8 servings


    • 3 pounds small carrots with tops (any color)

    • 2 tablespoons vegetable oil

    • Kosher salt, freshly ground pepper

    • 1 garlic clove

    • 3 tablespoons macadamia nuts or pine nuts

    • 1/2 cup (packed) fresh basil leaves

    • 1/4 cup finely grated Parmesan

    • 1/2 cup extra-virgin olive oil


  1. Preheat oven to 400°F. Trim carrot tops, leaving some stem attached. Measure out 2 cups carrot tops and set aside; reserve any remaining carrot tops for another use.
  2. Toss carrots and vegetable oil on a rimmed baking sheet; season with salt and pepper. Roast, tossing occasionally, until carrots are golden brown and tender, 25-35 minutes. Let cool.

  3. Pulse garlic and nuts in a food processor until a coarse paste forms. Add basil, Parmesan, and reserved carrot tops; process until a coarse purée forms. Add olive oil and pulse until combined; season with salt and pepper. Serve carrots with pesto.

DO AHEAD: Pesto can be made 1 day ahead. Press plastic wrap directly onto surface; chill. Carrots can be roasted 4 hours ahead. Let stand at room temperature.
