Tasting Table says most of the brands make their products using a combination of soy flour, canola oil, artificial colors, various flavors, and thickeners, to preserve the flavor and texture.
Other brands you may recognize, such as: It’s Delish, Frontier Co-Op, and Cool Foods, all make plant-based versions of bacon bits, too, so you can peruse a few varieties to pick your favorite. TBH, it’s always a good day when we remember (most) bacon bits are meat-free.
