Tempeh is a lot easier to find than it used to be, but can still be a challenge.
If a store has tempeh, it will almost always be right next to the tofu, which is usually either by the produce or dairy sections.
If your go-to grocery store just doesn’t have it, you have 2 options that will likely succeed.
First, if you have a Whole Foods near by, it’s your best option. Not only do they almost always have it, but it’s the best tasting of any tempeh that I’ve tried, and strangely cheaper too.
Here’s what it will likely look like (from my vegan guide to Whole Foods Market):
If that’s not an option, most health food specialty shops do have tempeh. Often higher prices, but a good option if you have no others.
Hopefully that will help you find tempeh, it’s an awesome food and protein source for vegans.
