Repurposing Leftovers: A Simple Way to Reduce Food Waste

Nearly 40% of all food in the United States is wasted. Now, not all of that food waste happens inside our homes. In fact, a lot of it occurs in restaurants, grocery stores, farm fields (where crops are left unharvested), and even in manufacturing facilities. But the one piece of that puzzle that we can help with is the food we fail to eat at home. What’s more, not only does reducing our food waste at home help the environment and food access for others, but it also saves us money (after all, the most expensive food in your house is the stuff you throw out).

One area of food waste for many of us is leftovers. For some people, leftovers are very unappealing. They find reheating meals or repeating a meal they have already eaten to be unappealing. For others, knowing what to do with leftover components of meals (e.g., what to do with your remaining rice, vegetables, or proteins) is a mystery and so they just let the food languish in the fridge. These are both understandable perspectives, so I want to share why I love repurposing leftovers and how to overcome each of these obstacles.

Why You Should Repurpose Leftovers

There are a number of reasons why I find repurposing leftovers to be deeply gratifying:

  1. It saves me time. After all, foods that have already been cooked are much faster to turn into a new meal than cooking a meal from scratch.
  2. I save money, both by reducing the number of groceries I buy and by fully using the groceries I do purchase.
  3. It pushes me to be more creative in the kitchen. Whether it’s by pairing ingredients I haven’t put together before or changing the flavor profile of a dish by adding seasonings, I enjoy being pushed to find new ways to bring life to ingredients.
  4. By turning the old ingredients into something new, I’m able to avoid eating the same meal again.

If gaining more time in your day, saving money, and reducing food waste sounds good to you, here are my tips on how to repurpose leftovers, organized by food type.

Veggie Cauliflower Fried Rice


Roasted, steamed, or sautéed, leftover vegetables can bring a nutritional boost and added heft to a second meal. I love to use them in:

grain salads are a great way to repurpose leftovers


Leftover grains are always a welcome addition in my kitchen. As my kids have developed bigger and bigger appetites, I have learned to appreciate how grains can stretch a meal, making it more filling and sustaining for their growing bodies. Some of my favorite ways to use up leftover grains include:

Grilled Quicki Souvlaki Sandwiches


Leftover proteins might be the simplest of all the leftovers to use up. I usually like to dice up my leftover protein (e.g., chicken, steak, tofu, beans, etc.) and then incorporate it into any of the ideas listed above in the vegetable and grain sections. But I also enjoy them added to pasta sauces or as a topping on homemade pizza.

Rainbow Vegetable Soup


When I first got serious about cooking leftovers, sauces felt like a challenge, so I usually just froze them until I needed to use them for another meal. I still do this often, but over the years I have figured out some other uses that are also very enjoyable. For instance, I like to use leftover sauces as a dip for veggies, as a topping for toast or bruschetta, as a different sauce for a pizza or flatbread, or mixed into soups.

Blueberry Basil Smoothie


If I am being honest, there is rarely leftover fruit available in my house, but when there is I add it to smoothies, mix it with a pinch of sugar and use it as a topping on plain yogurt, or add it to my bowl of granola in the morning.

[…] Search for the recipes that you plan to make in cookbooks, online, or with a meal planning service like The Scramble. Think about if there are ways to save time and effort by making extras to be eaten as leftovers, used in another dish (e.g., leftover rice can become fried rice, leftover protein can become fillings for paninis or mixed into pasta sauce, and leftover vegetables can be added to sauces, salads, chimichangas, or sandwiches), or frozen for another week.
