20 Creative Ways To Use Mason Jars For A Sustainable Lifestyle

Mason jars have a variety of uses that can help us downsize on plastic and non-recyclables and help keep our planet habitable for generations to come.


Plastic overuse, while gratefully declined since the 1950s, is still a heavy global problem.  10 million tons of plastic end up in our oceans every year, 80% of all sea birds are found with plastic in their stomachs and on top of that, plastic doesn’t biodegrade for thousands upon thousands of years.

But fret not, there are other options! While it may be tempting to use Tupperware or unbreakable plastic drinkware, there is an alternative option: mason jars.

Mason jars are durable, can often be dropped without breaking, and come with a seal tight lid that can be used over and over again without changing shape.


Mason jars were originally created for canning food to be stored and used at a much later date. They’re good for making preservatives and jams, but they have more every day uses as well.

The most obvious first choice! The edges of a mason jar are smooth and the jars come in many different sizes. The lid is water-tight as well, and doesn’t break easily if you toss it in your bag and bring it along with you.

  • Smoothies


If you like to whip up some smoothies in the morning rather than load up on carbs by eating a bagel or a muffin (like me!), bringing it along in a mason jar is a great way to do it. The mason jar’s clear, thick glass keeps in the cold and refrigerates easily if you want to save it for later. You can also buy a super cool coffee lid to put on your mason jar!

  • Coffee/tea


Your best bet here is iced coffee or tea, but the mason jar can handle heat like a pro too (you can put them in the oven or a microwave and the tempered glass works just fine).

  • Cereal


You can toss some cereal in a mason jar and put the milk in a separate container, or fill the glass half full with milk so the cereal at the top doesn’t get too mushy.


  • Salads

Food and Other Stuff

Mason jars are ideal for holding a mixed salad, and you can choose to either layer it or mix it all together. Your best bet if you want to keep a salad for a few days, put the dressing at the very bottom layer and put the dry ingredients at the top so they won’t soak (I learned that the hard way).

  • Microwavable food

Unlike plastic or Styrofoam containers that release some pretty toxic chemicals into your food when you microwave it, mason jars heat up your food without the fear of melting. Once you’re done, you can screw the lid back on and bring it back home to clean and reuse.

  • Dry snacks


Granola, fruit, trail mix, candy, cereals and anything else you can think of to snack on. Buy your snacks in bulk and then toss a handful into a mason jar rather than buying little individual snack packs that produce more plastic.

  • Yogurt Parfait

Rather than hit up an expensive café for a $6 parfait and a $5 coffee, all you need is a few mason jars. Buy a big tub of vanilla yogurt, blueberries, raspberries, strawberries and honey granola and you can make your own parfait every morning for multiple weeks – all for under $10 total. (Make  sure you add the granola the same day you plan on eating the yogurt to stop it from getting soft).


  • Leftovers

Chicken and rice? Mason jar. Meatball marinara? Mason jar. Soup? You guessed it, put it in the mason jar. Rather than find yourself with a fridge full of plastic Tupperware that easily gives way to mold, stick anything in a glass jar and it has unlimited uses.

  • Cooking

Just like you can bake in a mason jar, you can cook in one too. From pasta, to soups, to salads – if you’re low on cookware, you know where to turn.

  • Dessert


Tired of filling a baking pan? Bake a cake or pie inside the jar and voila – your own personal dessert! The jar is also great for storing ice cream!

  • Storing bulk items

Using mason jars in your pantry to store dry food is a great way to stay organized and keep your food fresh.
