Sometimes your eyes are bigger than your stomach, and your once-beautiful fresh produce starts to rot. Sure you can compost it instead of throwing it out, but the end result is still wasteful. It’s bad for your budget, worse for the environment, and could have been used by someone in need.
So try embarking on a new challenge: zero waste cooking. It’s all about learning how to make the most out of every herb, green and squash you buy, so you won’t have to toss them later.
We already covered how to store leftovers, fruits and vegetables, and pantry staples properly; so we’ve scoured the internet (and our favorite cookbooks) for zero waste recipe ideas and tips for how to use up the leftover bits of your vegetable and herbs. We also spoke with Azuré Keahi, Business Manager of our 1% for the Planet partner Soul Fire Farm to get some excellent tips, too. (Have kids that only seem to eat carbs? Keahi also shared great ideas for getting them to eat — and love — vegetables.)
Ways to Reduce Food Waste
Planning makes perfect: Meal planning will save your family from take out when you’re feeling crunched for time.
Keep a list: While you’re still shopping for the season, take stock of what’s already in the house before heading out, so as not to get seduced by new-to-you-goods when you already have something perfectly fine at home.
Fresh herbs can have a short life and are also a great thing to store in the freezer to reduce food waste. “One of my favorite things to do is to harvest a ton of parsley and roll it into a super tight log in a bag,” says Keahi. “I wrap each end with rubber bands and put it all into the freezer. You can then cut off parsley very easily for cooking later.”
If you find yourself with a surplus of fresh fruit, don’t just throw it in freezer bags to pry apart later. Instead cut it up, lay it out on metal sheet pans and freeze before storing in stackable containers.
Give wilted produce a second life: Root vegetables that have started to shrivel can sometimes be revived by a soak in a bowl of water, suggests Keahi. Add wilted greens or herbs into a curry, stew or soup where their texture will change anyway.
Or, compost: Depending on where you live, you might compost in your backyard or have curbside pickup. If you live in an apartment with no backyard or pickup, you may be able to compost at your local greenmarket.
Food Scrap Recipe Inspiration
Unconventional Pesto: Save carrot tops, cilantro and hardy green stems to use for alternative pestos. The recipe is the same as basil pesto: green + garlic + oil + nut + cheese = yum.
Quick Pickles: Got a spare container and an hour to kill? You too can make quick pickles . The hands on cooking time is under 5 minutes, and the results last up to 2 weeks. Better yet? You can reuse the brine for new veggies or to marinate chicken before roasting.
Veggie or Bone Broth: We’ve extolled the virtues of a pressure cooker before, and quick bone broth is a perfect example of its utility. You barely need a recipe for this: take veggie scraps including carrot peels, onion ends and skins, beet and carrot tops, elderly garlic, corn cobs and add them to about four cups of water and chicken bones (if you like). “I am a nerd about saving flavorful scraps in the freezer for vegetable stock,” says Keahi. “Once I’ve filled a gallon bag, I know it’s time to fill my pot with water, salt and veggie scraps!”
If you want to add even more flavor, Michelle Tam from Nom Nom Paleo adds about three tablespoons of fish sauce to her broth.
Kimchi and Relish: Instead of tossing kale or collard stems after de-ribbing the leaves, “they’re great for fermenting (kale stem kimchi!) or pickling,” suggests Keahi. Blend pickled stems in the food processor to turn them into a tangy sauce or—with less pulsing—a relish.
Squash Bread: After roasting winter squash, save the skins to add to bread, muffins or cake, such as this Squash Challah Bread by artist and baker Ellie Markovitch. “Similar to banana bread, squash skins add incredible texture and moistness to baked goods,” says Keahi. Blend roasted peels in the food processor to make them easier to mix in.
Roasted Beet Spread: Roast shriveled beets, then add them to a food processor along with some chili pepper, yogurt, cumin and garlic to make an amazing—and beautifully bright pink—spread, recommends Keahi. Top with olive oil and zaatar. “It’s one of my favorite things on earth.”
