Cooking with a sous vide device is more flexible than many home cooks realize. When I first began, I assumed vacuum-sealed plastic bags were the only option. Over time I discovered glass jars—especially mason jars—are an excellent alternative for many recipes. I’ve tested numerous brands and sizes, and this guide highlights the best mason jars for sous vide use and other kitchen tasks.
Mason jars are versatile beyond sous vide: they store stocks, soups, sauces and make attractive serving vessels. Below I explain what works best in jars, compare jars to plastic bags, outline recommended sizes, cover safety tips, and review top jar choices for sous vide cooking.

What to Sous Vide in a Mason Jar
Mason jars work especially well for preparations that contain liquids or are served directly from the jar. Desserts, custards, cheesecakes, and egg bites are popular choices because the jars make for neat single-serve portions and easy presentation. Examples include chocolate espresso pot de crème, pumpkin spice custard, crème brûlée, and various sous vide cheesecakes.
Jars are also ideal for infusions—alcohol, oils, or flavored syrups—because they seal well and are easy to shake and store. You can even drink or serve the infusion from the jar. Pickling and sous vide coffee are two other excellent jar applications. In general, any recipe with a significant liquid component benefits from being cooked in a jar.
Finally, jars are convenient for meal prep and reheating. Store leftovers in a jar and reheat them in your sous vide bath for even, gentle warming without drying out the food.
Jars Vs. Plastic Bags in the Sous Vide
Both jars and plastic bags have their place. For solid cuts of meat, fish, or other items where maximum surface contact with the water is important, vacuum-sealed plastic bags are the better option. Bags let hot water surround the food evenly, which is ideal for proteins and many vegetables.
Mason jars shine with liquids, custards, infusions, pickles, and any preparation you plan to eat or serve directly from the vessel. Jars are reusable and reduce single-use plastic waste, which is an important consideration if you want to lower your environmental impact. For fruits and many vegetables, bags are often more practical, though jars can work for pickling and some preserved items.
What Size Mason Jar is Best?
There’s no single “best” size—choose based on your recipes and portion sizes. Common useful sizes include 8, 12, 16, and 32 ounces. If you plan to eat from the jar, wide-mouth jars are more comfortable for spooning and scooping. A mix of standard and wide-mouth jars gives the most flexibility. Also consider jars with decorative textures if you’re serving guests or giving food as gifts.
Is it Safe to Use Mason Jars in the Sous Vide?
Yes—mason jars are safe for sous vide when used correctly. To avoid thermal shock, place jars in the water bath before bringing the bath to temperature rather than dropping cold jars into hot water. Use glass canning jars designed for food; they tolerate the steady temperatures used in sous vide cooking. Screw the lids finger-tight only—do not overtighten—and avoid ball-top or nonstandard lids that may not seal reliably.
