Oats are a cereal grain grown in temperate areas. They grow well in cool climates and can tolerate more rain than other cereal grains. Oats are used as a cereal and in baked goods. They're also commonly used as livestock feed and occasionally used in soups.

Common Oat Grain Cuts

  • Whole oat groats are the whole grain of the oats, minus the hulls. They take the longest to cook.
  • Steel-cut oats are groats cut into 2 or 3 pieces with a sharp blade. They cook more quickly than whole oat groats and retain a nice, chewy texture.
  • Scottish oatmeal is a stone-ground oatmeal. The groats are ground and broken into small bits.
  • Rolled oats (old-fashioned), are the oat groats steamed and rolled into flakes. This means the oils are stabilized, and the oats stay fresh longer. The larger surface area means they will cook more quickly than steel-cut oats.
  • Quick oats are cut into more pieces, rolled thinner, and steamed longer. They will not have as much texture as the rolled oats or steel-cut but will cook more quickly.
  • Instant oats are usually very similar to (if not the same as) quick oats but might be pressed even thinner and cut even smaller. They might become rather mushy when cooked but generally, need very little cooking time.
  • Oat bran is the outer layer of the oat grain, just under the hull. Oat bran is part of rolled oats and steel-cut. Oat bran can also be purchased separately.
  • Oat flour(or ground oats) is sometimes combined with other gluten-free flours for gluten-free baked goods.

Oats For Baking and Substitutes

For baking, regular rolled oats and quick-cooking are usuallyinterchangeablein a recipe. If your recipe calls for quick-cookingoats and you only have old-fashioned rolled oats, pulse the old-fashioned oats in the food processor a few times. If quick-cooking oats are used in a recipe in place of old-fashioned rolled oats, the texture will be different, but that will probably matter very little in most recipes.

You can also make oat flour, or ground oats, from oats. All you need is a blender or food processor to make ground oat flour. The gluten-free ground oats can be used to replace flour in many recipes.

Oat Storage

Oats have ahigher fat content than other cereal grains and can go rancid if on the shelf for too long. Buy oats in small amounts and store them in a tightly covered container in a cool, dry place.

Oat Recipes

Use oats as a hot cereal, in cookies and other baked goods to make gluten free, or as a filler in meatloaf or meatballs.
