Oat groats are the whole, intact kernels of the oat plant (Avena sativa) with only the inedible outer hull removed. Because they remain minimally processed, oat groats retain the bran, germ, and endosperm, preserving the grain's naturally occurring fiber, protein, vitamins, minerals, healthy fats, and unique phytochemicals. They have a pleasantly chewy texture and mild, nutty flavor that becomes creamy when cooked.

As the least processed form of oats, oat groats provide all of the nutritional benefits associated with whole oats, including beta-glucans, avenanthramides, and a wide variety of vitamins, minerals, and antioxidant compounds. Although they require a longer cooking time than rolled or steel-cut oats, their hearty texture makes them an excellent choice for grain bowls, salads, soups, pilafs, breakfast porridges, and meal prep.
