As were all hunkering down and self-quarantining to protect ourselves and the community from the coronavirus outbreak, the Centers for Disease Control and Prevention recommends having at least a two-week food supply on hand.

So, youve probably made a couple of trips to the grocery store to stockpile some necessities. With a lot of that shopping being done in a panic and stores running out of items, you may have ended up buying things not usually on your grocery list or overloaded on some of your usual staples.

Either way, its important to use all the food you buy and avoid wasting it . Even outside of a pandemic, families waste $1,500 per year on food they never eat.

Even during a pandemic, its possible that people buy foods that they think they should eat instead of foods they want to eat, which can lead to unnecessary food waste, said Alyssa Pike, registered dietitian and manager of nutrition communications at the International Food Information Council Foundation .

Keeping track of whats in your fridge and pantry and learning which foods to prioritize will keep you from wasting too much food and help you make do and, even make some delicious meals with what you already have. Heres how.

Practice the first in, first out rule

Professional kitchens abide by the first in, first out , or FIFO, rule. That means storing older foods in the front of your refrigerator or pantry, and newly purchased items behind them, in the back. This is a good practice for home kitchens, too, said Celine Beitchman, director of nutrition at the Institute of Culinary Education .

You dont want to just keep shoving groceries into wherever you can fit them, she said. You want to have some sense of organization as to where you put them.

Place fresh fruits and vegetables in the easiest-to-grab spot in the refrigerator, along with milk and other dairy with the soonest expiration dates. Arrange canned goods, pasta and other pantry items so that those with the soonest use by or sell by dates are front and center.

We know that whatever is at the very front of the line is the thing that we should use first, and whats behind that is the thing that weve maybe just bought, Beitchman said. So, were always kind of moving inventory around so that weve got that FIFO going.

Eat fresh produce first

Any fresh fruits and vegetables should be used first, said Kris Sollid, registered dietitian and senior director of nutrition communications at the International Food Information Council Foundation.

Try using the ripest first, and map out a schedule for using the others as close to their peak ripeness as possible, he said.

Storing fruits and vegetables properly, with leafy greens in the refrigerator and onions and garlic in a dry, dark space, for example, will extend their shelf life.

But just because something starts to look wilted or mushy doesnt mean it should be thrown away. Freezing or cooking produce can make it last longer.

Over-ripe bananas turning brown can be stored in the freezer or used in smoothies or baked goods, Sollid said.

Greens can be blanched, and vegetables, like tomatoes, squashes and carrots, can be roasted. Toss cooked veggies into soups or casseroles, or freeze them, Beitchman said.

Even better, make a soup or casserole with the fresh vegetables. Leftovers can be stored in the fridge for three to four days, or portion the meals out and freeze for up to three months.

FIFO goes for meat and dairy, too

Practice FIFO with meat and dairy, Beitchman said. Keep track of use by and sell buy dates and, like produce, consider freezing or cooking to make them last longer.

Uncooked meat can be stored in the freezer for four to 12 months, and cooked meat for two to three months, according to the U.S. Department of Agriculture. Milk, cheese and other dairy also freeze well.

Beitchman suggests portioning everything out first cut cheese into slices or chunks, freeze milk in ice cube trays and freeze meat in serving sizes that make sense for your family.

Another option for using up milk and cheese nearing its shelf life: Make a bchamel sauce . The versatile cream sauce can be used in mac and cheese, lasagna or other casseroles.

Keep up with expiration dates of pantry items

After youve made use of fresh produce, meats and dairy, look to the freezer next. Frozen foods, whether store-bought or homemade, are usually more perishable than canned foods or other pantry items, said Claudia Sidoti, principal chef at HelloFresh .

But, it depends on the dates, so that is the most important thing to check, she said, urging home cooks to put the date on anything they freeze.

Date labels on packaged foods can be confusing . Theyre usually not based on science and usually offer a guide for when a food is at its best, not necessarily that something is unsafe to eat.

A useful tool is the FoodKeeper App , created by the USDAs Food Safety and Inspection Service. It lets you search for foods and provides guidelines for when to consume them for optimal freshness and quality.

Pantry items may still be safe to eat even if theyre recently expired, Sidoti said. If something looks or smells off, or youre doubtful, throw it away.

You can always cook anything thats about to expire, and dont forget items like flour and grains also have expiration dates.

Cook up the pasta and store it in a Ziploc bag and then stir into soups, or make a crazy mixed-shape mac and cheese and portion it up and freeze it, Sidoti said.

Get creative with what you have on hand

You may end up with a random collection of ingredients, so getting creative in the kitchen is a must. Combining shelf-stable items like beans, pasta, rice and canned foods with fresh and frozen foods is the best way to make balanced recipes and use what you have in stock, Sollid said.

Making soups, chili or casseroles lets you combine different ingredients in unique ways, Sidoti said. Check out Pinterest, Google recipes for the ingredients you have or refer to the cookbooks collecting dust on your bookshelves for ideas.

If you look at cookbooks from the 50s, when casseroles and bakes were popular, its kind of crazy to see what combos of canned ingredients home cooks were using, Sidoti said. With time on your hands, get creative, look up ways to use your ingredient that you are struggling to find a use for. Have fun with it and take some risks.

Swap out ingredients and experiment with dried herbs and flavors, like honey or maple syrup, to use up foods and keep from getting bored with eating the same dishes over and over, Beitchman said.

Even while youre hunkering down, try to eat as healthy as possible with multiple food groups and lots of fruits and vegetables, whether theyre fresh, frozen or canned, Pike said.

Make the best choices you can based on whats available, what you enjoy and will actually eat, whats convenient and within your budget, she said.
