Is Tempeh Gluten-Free? (Find Out Now!)


Is Tempeh Gluten-Free

Plant-based diets are on the rise. With more people opting for less meat, plant-based protein sources, such as tempeh, are popping up more frequently. For those following a gluten-free diet, is tempeh a gluten-free meat alternative?

Traditional tempeh is gluten-free as it is made from only soybeans and vinegar. However, many store-bought forms of tempeh contain wheat. If you are looking for gluten-free tempeh, Lightlife, Soy Boy, and Mari Gold Health Foods all offer gluten-free tempeh. The best gluten-free alternatives to tempeh include Nasoya Organic Tofu, Anthony’s Textured Vegetable Protein, and Butler Foods Soy Curls.

Now that we know some tempeh options can be gluten-free, let’s take a deeper look into tempeh, its health benefits and some of the top-rated gluten-free alternatives on the market. 

What is Tempeh

Those on a plant-based diet are most likely familiar with tempeh but for those of us who aren’t vegan or vegetarian, it may seem very foreign. Tempeh is a fermented soy product that is commonly used as a plant-based protein alternative or meat replacement. Tempeh consists of fermented soybeans that are then pressed together into a cake that sometimes contains wheat. It has a slightly chewy texture and nutty flavor.

Health Benefits of Tempeh

Tempeh is a rich source of many nutrients. Because of the fermentation processed, tempeh is a good source of probiotics as well. These are the beneficial bacteria that support a healthy gut and digestion. Tempeh is also a good source of prebiotics, the fiber needed to support the growth of probiotics [1].

Tempeh is best known for being an excellent plant-based protein source. Protein is essential for satiety and high protein diets have been associated with increased fullness and decreased hunger. Plant-based proteins are associated with decreased cholesterol and triglyceride levels compared to animal proteins. A lot of this is attributed to the low saturated fat content and isoflavones present in soy [2, 3].

All-Natural Gluten-Free Alternatives to Tempeh

For those looking for gluten-free, plant-based meat alternatives that take a more natural approach, consider using jackfruit or mushrooms. With a similar, meaty texture, these items can replace tempeh or meat in a variety of dishes.

Native Forest Organic Young Jackfruit

Although it is not as protein rich as tempeh, jackfruit can simulate the texture of shredded meats and work well as an alternative protein for tacos, casseroles and more. Jackfruit is mild in flavor, similar to tempeh and tofu, and takes on the flavors of its seasonings.

Native Forest organic young jackfruit is a convenient plant-based alternative. For those looking to cut out the additional salt or choose a slightly less processed approach, try grabbing a jackfruit in the store. To obtain the meat of the jackfruit it needs to be boiled and then peeled to reveal the seed pods. The seed pods can be eaten once the seeds are removed, along with the flesh surrounding the seed pod.

For those who have never tried jackfruit before, a pre-prepared version may be best to start. You can find this product online at Amazon.com priced at $73.99 for a set of 12 14-ounce cans.

Ingredients:

  • Organic young jackfruit
  • Water
  • Sea salt
  • Organic lime juice

Shiitake Mushrooms

Similar to jackfruit, Shiitake mushrooms are not a good source of protein. However, they have a mild flavor and a meaty texture that makes them great as a plant-based meat alternative. Rich in nutrients yet inexpensive, Shiitake mushrooms can work well as a naturally gluten-free substitute for tempeh. You can find Shiitake mushrooms at most retail grocers, including Walmart and Publix, priced at $3.98 for a 3.2-ounce container.

  • Shiitake mushrooms

Homemade Tempeh Recipe

For those interested in making their own tempeh, you will be surprised to learn how easy it can be. Remember, if making your own tempeh at home, always be sure to cook your tempeh before eating it to eliminate risk of foodborne illness.

Ingredients:

  • 1-pound dried, whole soybeans
  • 2 tablespoons white vinegar
  • 1 teaspoon tempeh starter

Instructions:

  1. Place soybeans in a large bowl and cover completely with water to soak overnight, or at least 12 hours.
  2. Once the beans have soaked, remove the hulls, the outer skins surrounding the beans. You can do this with your hands or a potato masher to loosen the skins. The hulls will float to the surface where they can be skimmed from the water and discarded.
  3. Drain and transfer hulled beans to a large pot with fresh water. Boil then reduce heat to simmer, partially covered, until beans are tender (about 45 minutes.)
  4. Take 2 Ziploc bags and pierce a hole in 1-inch intervals using a toothpick or skewer.
  5. Once beans are done cooking, drain and spread them out to dry on a towel-lined baking sheet until they are cool.
  6. Transfer dried and cooled beans to a clean bowl and sprinkle with vinegar until evenly coated.
  7. Next sprinkle tempeh starter over the beans and evenly distribute.
  8. Separate and place your beans in the two Ziploc bags, seal and flatten evenly.
  9. Bags must be incubated between 85-90 degrees Fahrenheit for 24-48 hours.
  10. The tempeh is done when the surface is covered completely with a layer of white mycelium.
  11. Remove from heat and let cool.
  12. Store in refrigerator for up to 1 week.

Is Tempeh Supposed to Look Moldy?

Mold spots on your tempeh are a byproduct of the fermentation process. These may look like small, dark spots on the surface and are completely normal and edible. They do not affect the flavor or safety of the product.

Does Tempeh Need to be Cooked?

If you purchase your tempeh from the grocery store and it is pasteurized, it does not need to be cooked. Unpasteurized tempeh or homemade tempeh should always be cooked to reduce risk of foodborne illness.

Can Tempeh Spoil?

Yes, once opened tempeh can continue to grow mold and spoil. The best way to tell if your tempeh has gone bad is to feel the texture and use your sense of smell.  A slimy texture and off-putting odor are your biggest indicators that it’s time to toss the tempeh.
