Vegetable Stock From Scraps: Zero Waste Recipe

Isn't it great when you can make something out of nothing? Even better, what if the something you make is tastier and healthier than what you can buy in the store? Homemade vegetable stock is a wonderfully easy and zero-waste recipe that you can make from your vegetable scraps!

This rich and tasty stock gets its flavor from simmering any scraps you have from cooking, such as peels, stalks, and stems from carrots, celery, fennel, leeks, onions, garlic, and more. Once you have made this delicious basic vegetable stock, you can use it in soups, sauces or even oil-free or low-oil sautés.

Say goodbye to commercially prepared bouillons and stocks forever. You will save money, eat healthier, and be kinder to the earth by producing less waste.

Vegetable stock vs. broth

Classically a stock is made from simmering animal bones for several hours. Since this recipe is for a basic vegetable stock, we instead simmer vegetable scraps. Simmering the veggie scraps for hours creates a deeper and more fortified liquid than a typical veggie broth. A veggie broth is much thinner and made in a shorter time than a stock. This recipe is a veggie stock because we will simmer it for three hours, producing a deep and richly flavored liquid.

What can I do with vegetable scraps?

Save your veggie scraps for your stockpot

When preparing weekly meals, there are lots of scraps to deal with, particularly if you eat a lot of vegetables and fresh herbs. Carrot and potato peelings, vegetable ends and tips, tough celery and leek stalks, and herb stems from rosemary, parsley and thyme are all by-products of cooking.

These vegetable byproducts do not need to be thrown away. Besides the obvious solution of composting, making vegetable stock is another great answer to the problem of food waste. The stock helps you get the benefits of these fresh vegetables, such as the liver-supporting power of garlic or the prebiotic punch of onions. Save all the peels and trimmings from your meal prep and put them into sealable freezer bags or airtight containers in the freezer until there's enough to make this recipe. Then use your homemade stock to add flavor to all your favorite recipes that call for stock, broth or bouillon.

Can you use vegetable peels for stock?

Vegetable peels are an excellent addition to vegetable stock. Take all your veggie byproducts—such as peels and ends from onions, garlic, potatoes, parsnip, carrots, fennel, celery and zucchini—and save them for your stockpot. These will help make your stock tasty, cost-efficient, and low waste.

What other kitchen scraps can be used to make stock?

Mushrooms and fruit rinds are great stock ingredients

Peels and ends are not the only veggie scraps that go well in a stock. Mushrooms, corn cobs, tough stalks, and stems are all welcome stock additions. You may be surprised to learn that lemon rinds are also a great flavor enhancer.

I love adding all the stems and herb ends that would normally get wasted into my stocks. Likewise, dried leftover thyme, unused green onions, and sad carrots all get a new life in my homemade vegetable stock.

What should you not put in vegetable stock?

Although vegetable stock is a great way to use up veggie scraps, there are a few things that you should not use.

  • To avoid a bitter taste, leave the broccoli, Brussels sprouts, and cauliflower stems for other zero-waste recipes. These cruciferous vegetables are breast health superstars and are good in dishes like grated slaws.
  • Any vegetable with a strong flavor will dominate your stock. An example of this is asparagus. Unless you are making an asparagus soup or risotto with the stock, the flavor is too strong. Instead, stick with milder vegetables like celery, carrots, mushrooms, cauliflower and others.
  • Another vegetable to avoid is beet. Beets are great in a healthy juice or smoothie, but they aren't good in this recipe, because the stock's color and flavor will be affected greatly.

Your recipe really depends on what kinds of scraps you have on hand. To get wonderful vegetable stock with whatever scraps you have, follow this easy formula.

The preparation of vegetable stock couldn't be easier. It is an extremely low-maintenance recipe that has fantastic results.

  • Hourly, check the stock, skim off any foam or "scum" that can rise to the surface, and dispose of it.
  • Once the stock is finished, strain the stock thru a fine mesh strainer or colander to take out all the scraps (which can be added to your compost). Be careful not to burn yourself.
  • Let the stock cool completely, then store in a sealed container in the refrigerator for seven days, or in the freezer for up to three months.

Tip: Pour the stock into ice cube trays and freeze to make little flavor infusions for quick sauté dishes!

Does vegetable stock go bad?

Homemade vegetable stock is made without the sodium and additives of store-bought stock

Like all food, vegetable stock will go bad with time. With proper storage, it should keep for a week in the fridge or up to three months in the freezer. As with all foods, signs of spoilage include a sour smell or taste, a fermented smell, or bubbling.

Why make vegetable stock? 3 Health Benefits

One of the best reasons to make your own vegetable stock is for its health benefits.

  2. Vegetable stocks can be a great replenishing source of electrolytes and hydration.
  3. Some even tout vegetable stock as wonderful digestive support, and stock or broth is commonly recommended when your stomach is feeling particularly sensitive.

Do I need to take digestive supplements if I eat vegetable stock?
