Ingredients you will need

uncooked rice noodles, tofu, and vegetables on a tabletop with mason jars behind.

Miso- This can be found in the refrigerated section of many grocery stores as well as natural food stores and Asian markets. It is commonly called soybean paste and has a mellow, slightly sweet flavor.
Soy Sauce- If you need your soup to be gluten-free, substitute tamari.
Sweetener- Pure cane sugar is my preference, but other options could include date sugar/syrup, maple sugar/syrup, or others.
Tofu- Made from soybeans, tofu is sold in block form in a variety of textures that range from silken to extra firm, and they differ mainly in the amount of water retained. Tofu can be found in the refrigerated section of many grocery stores as well as natural food stores and Asian markets. The shelf-stable variety is sometimes a little more difficult to find in stores, but it doesn’t need to be refrigerated. I order mine online and have it shipped right to my door.
Noodles– I like to use glass noodles, also called harusame, cellophane, or bean thread noodles. They are thin, transparent, gluten-free noodles made of potato or sweet potato starch. Rice vermicelli noodles are made from rice flour and water and are also a great option. You can use these types of quick-cooking noodles in spring rolls, noodle salads, stir-fries, vegetable soups, and hot pot dishes. They are clear, silky-smooth, and have a delightful chewy texture. Their neutral flavor soaks up broths, soups, and seasonings well.
Vegetables- The veggies chosen to use are based on your preference. Some of my favorites are napa cabbage, broccoli, and carrots. I have included a full list of more ideas in the next section.
Sesame seeds- You don’t have to use white and black sesame seeds, but they do offer two different flavors so if you have them on hand, it adds to the complexity of the flavor.

Tips & Suggestions

Layering: I like to add the glass noodles to the jar first so I can be sure they’re completely immersed in the water.
Noodles: Feel free to mix it up and use any variety of fast cooking or precooked noodles. Be sure the noodle you choose doesn’t need to be rinsed.
Veggies: Frozen veggies work very well in this soup-in-a-jar recipe.
Temperature: Do not put boiling water into a jar straight out of the fridge. Let the jar warm to room temperature before adding the boiling water. Rapid temperature changes can result in broken glass.
Safety: I recommend not shaking the jar once you add the water, stirring is sufficient. Pressure builds in a jar with boiling water and shaking can amplify that process. Use oven mitts or a kitchen towel to handle a hot jar until it cools.

How to make soup in a Mason jar

The recipe card at the bottom of the page has the full list of ingredients with measurements and instructions.

STEP #1: I like to begin by adding the glass noodles or vermicelli rice noodles to the jar first so that they’re on the bottom, and I can be sure they’re completely immersed in the water. See the best type of jar to use in the section below.

STEP #2: Gather your choice of add-in ingredients. Choose ingredients for each jar depending on how long it will be before you use them. For instance, I would only add tofu and bean sprouts to a jar I plan to eat within 3 days. Slice add-ins into bite-size pieces and drop them into the canning jar.

STEP #3: Add your three soup-broth ingredients–soy sauce, miso paste, and sweetener–to the top of the jar, put on the lid, and refrigerate.

STEP #4: When you are ready to eat, remove the lid, boil 2 cups of water, and pour over the ingredients in the jar. Make sure the jar has reached room temperature before carefully adding the boiling water. Alternatively, add 2 cups of cold water to your jar and heat in a microwave for 2-3 minutes on high power.

STEP #5: Place the lid on the jar but do not shake the jar; pressure builds up from the hot water. Allow it to sit covered for 4-5 minutes, stir, and EAT!

Add-in options

Toasted sesame seeds (white, black, or both)
Napa Cabbage or Boy Chok
Carrots
Broccoli
Mushrooms (Shitake, enoki, button, etc)
Tofu
Bean Sprouts
Edamame, frozen, or snap peas
Water chestnuts
Bamboo slices
Kimchi (for a little extra spice)

The best jar size to use

Use a 24oz or 32 oz canning jar with a wide mouth. A wide mouth makes it easier to add ingredients and to eat from.

Any quart-size wide-mouth canning jar and sealable lid will work (Ex: Ball, Mason, Anchor, etc.) Your jar needs to be able to withstand boiling water temperatures without cracking. Most smooth-sided jars are not designed to be used at high temperatures.

Frequently Asked Questions

Can you use any type of jar for mason jar soup?

Yes, but it’s best to use wide-mouth mason jars that are heat-resistant, such as those made from tempered glass, which can safely handle hot water. Make sure the jars have tight-fitting lids to prevent spills and maintain freshness. See my notes above.

What are some good ingredients to include in mason jar soup?

Great ingredients for mason jar soup include pre-cooked noodles, fresh or frozen vegetables, tofu or beans for protein, and seasonings like garlic, ginger, and soy sauce. You can also add miso paste or bouillon for extra flavor, and top with fresh herbs before serving.

How long will it last?

This soup base can be stored in the fridge for up to 5 days. It’s fine to food prep and add all ingredients ahead of time as long as they won’t spoil before you consume them. For instance, I would use my bean sprouts and tofu ingredients at the beginning of the week.
