Reducing Food Waste in Your Kitchen

Why Should I Care?

One of the most immediate benefits of reducing food waste is saving money. You might be surprised to learn how much of your grocery budget ends up in the garbage through spoiled produce, forgotten leftovers, and expired products.

There are also environmental consequences. Producing food requires resources such as water, land, energy, and labour. When food is discarded, all of these resources are wasted too. Plus, food that ends up in landfills decomposes and produces methane, a greenhouse gas that contributes to climate change.

What Can I Do?

Plan Before You Shop

A successful strategy for reducing food waste begins before entering the store. Stop showing up at the grocery store with no idea of what you’ll be cooking and eating this week. This is how you end up with miscellaneous ingredients that you wont use together in meals. Meal planning helps ensure that food purchased has a purpose and is more likely to be used.

Before shopping, take inventory of what is already available in the refrigerator, freezer, and pantry. Make a list of ingredients that need to be used soon and plan meals around them. Creating a shopping list based on planned meals can help prevent impulse purchases and reduce the likelihood of buying more food than needed.

Shopping with a list can also make grocery trips more efficient, take less time, and help you stay within your budget.

Understanding Date Labels

Many people throw away food because they misunderstand date labels. In most cases, "best before" dates indicate quality rather than safety. Foods may still be safe to consume after the best before date if they have been stored properly and show no signs of spoilage.

Learning the difference between "best before" dates and expiration dates can help prevent unnecessary waste. Instead of automatically discarding food based on the date, use your senses to assess freshness. Check for unusual smells, textures, or visible signs of spoilage.

Store Food Properly

Proper food storage can dramatically extend the life of perishable foods. Different fruits and vegetables have different storage needs, and understanding these requirements can help reduce spoilage.

Leafy greens should be stored in the refrigerator and kept dry to prevent wilting. Fresh herbs can last longer when stored upright in a container with a small amount of water. My favourite hack is placing the root end of green onions in a small mason jar filled with water and placing it on my kitchen counter or dining table. The green onions can regrow multiple times and be used again and again. Planting them in soil once the roots have matured more can result in even better growth. Berries should generally remain unwashed until ready to eat, as excess moisture can speed up spoilage (or simply let them dry before storing in the fridge.)

Many fruits, such as bananas, avocados, and peaches, continue ripening at room temperature and can be refrigerated once they reach the desired level of ripeness.

Keeping the refrigerator at the correct temperature, typically 4°C (40°F) or below, also helps preserve food quality and safety.

Use the FIFO Method

The "First In, First Out" method involves placing older foods at the front of the refrigerator, freezer, or pantry and newer purchases behind them, which can help reduce the chance of forgetting about them. 

This system encourages you to use foods that have been stored the longest before opening newer items. It is commonly used in restaurants and food service operations and works just as well at home!

Freeze Foods Before They Spoil

I use my freezer for everything! Freezing is one of the most effective ways to prevent food waste. Many foods can be frozen when it becomes clear they will not be used before spoiling.

Bread, cooked meats, soups, sauces, fruits, vegetables, and leftovers can all be frozen for later use. Bananas that are becoming overripe can be peeled and frozen for smoothies or baking. Fresh herbs can be chopped and frozen in ice cube trays with water or olive oil. Parmesan rinds, bone broth, fresh pasta, minced garlic, extra tomato paste, and beans are just a few examples of things I keep in my freezer to have on hand when I need them.

Labeling frozen foods with the contents and date can make it easier to use them within a reasonable timeframe.

Get Creative with Leftovers

Leftovers are often overlooked and forgotten, eventually ending up in the garbage. Planning for leftovers can help reduce waste and save time on meal preparation.

Cooked vegetables can be added to soups, stir-fries, omelets, or pasta dishes. Leftover chicken can become sandwiches, wraps, salads, or tacos. Rice and grains can be transformed into fried rice, grain bowls, or casseroles.

Designating one meal each week as a "use-it-up" meal can be a fun and practical way to clear out ingredients before they spoil.

Be Realistic with Your Purchases

Fresh produce is nutritious and delicious, but buying more than can reasonably be consumed often leads to waste. Be realistic about how much fresh food you can eat before the next grocery trip.

Consider purchasing smaller quantities of highly perishable items and restocking as needed. You don’t need to buy the bulk package of something if you’ll end up throwing half out anyways. Frozen fruits and vegetables can also be excellent alternatives because they have a much longer shelf life while still providing valuable nutrients.

Make Food Waste Reduction a Household Habit!!

Reducing food waste does not require perfection. Small changes can make a meaningful difference over time. Planning meals, storing food properly, freezing extras, and using leftovers creatively are simple habits that can significantly reduce waste.

By wasting less food, households can save money, protect the environment, and make better use of the resources that go into producing the food we eat. Every meal is an opportunity to make choices that benefit both our wallets and the planet.
