Steel Cut Oats vs. Rolled Oats: How Do They Compare?

Oats (Avena sativa) are a species of whole-grain cereal cultivated for its edible seeds of oat grass. The cereal grain, which is also used to feed livestock, is a hearty breakfast staple commonly used in hot cereals like porridge and cold cereals like muesli and granola. Oats are typically processed into different forms such as rolled oats, steel-cut oats, and instant oats. The least processed form of oats, oat groats, require long cooking times.

Oats have numerous purported health benefits: The cereal grain is a strong source of daily dietary fiber, with four to five grams of fiber per serving on average. The beta-glucan in oats, along with their lower glycemic index level, has been shown to help lower cholesterol and blood sugar levels, reducing the risk of heart disease. Though oats are gluten-free, people with celiac disease may want to steer clear of oats that aren’t specifically labeled gluten-free, as they are sometimes grown or processed near other grains that contain gluten.

There are many different kinds of oats, each with their own benefits. Here are a few of the most popular types of oats you may find in the grocery store.

1. 1. Oat groats: Oat groats, or whole oats, are the most whole form of the grain. Only the hull has been removed from the oat kernels, leaving the oat bran, endosperm, and germ of the oat. Oat groats take the longest time to cook—around thirty to forty minutes—and are typically prepared on the stovetop.
2. 2. Rolled oats: Rolled oats, or old-fashioned oats, are made by steaming oat groats and rolling them flat between steel rollers, giving the oats a flat appearance. Rolled oats are a popular choice for making porridge, granola, or oatmeal cookies.
3. 3. Steel-cut oats: Steel-cut oats are made by cutting the oat groats into smaller pieces using steel blades. Also known as Irish oats, steel-cut oats have a chewy texture.
4. 4. Scottish oats: Scottish oats are made by stone grinding oat groats into a finer texture than steel-cut oats, making them the perfect option for making porridge.
5. 5. Quick oats: Quick oats are similar to rolled oats. They are also made by steaming the oat groats and then rolling them flat. However, quick oats are rolled flatter than old-fashioned oats, and sometimes also cut into smaller pieces so that they cook faster.
6. 6. Instant oats: Instant oats are a form of rolled oats that have been precooked and cut into smaller pieces so that they can be cooked very quickly to make instant oatmeal, which involves steeping the oats in hot liquid for a few minutes. They are the most processed form of oat.

Steel-cut oats and rolled oats are two of the most popular kinds of porridge and oatmeal oats. You can find either at any local grocery store, but here are some of the differences between the two to help you decide which is right for you.

1. 1. Production: The primary difference between steel-cut and rolled oats is how they are processed. Steel-cut oats are made as the name suggests, by cutting the oats into smaller pieces using a steel blade. Rolled oats are steamed and then rolled flat. This means that they absorb liquid more quickly than steel-cut oats.
2. 2. Cooking time: Rolled oats cook in less time than steel-cut oats because they have already been steamed. A bowl of rolled oats takes roughly ten minutes to cook, while a bowl of steel-cut oats can take from fifteen to twenty minutes.
3. 3. Texture: When you cook steel-cut oats, they take on a very chewy texture that clumps together. When you cook rolled oats, they become silkier and runnier than steel-cut oats.
4. 4. Health benefits: The nutritional value of both types of oats are very similar, but rolled oats are slightly higher in calories and carbs than steel-cut oats. Steel-cut oats are slightly higher in protein and soluble fiber content than rolled oats.
5. 5. Uses: Rolled oats are a more versatile grain and are often used in baking recipes. Rolled oats can be used in biscuits, cookies, granola bars, cakes, and muffins. Steel-cut oats are most often used to make porridge.

No matter what kind of oats you choose, they are a healthy eating pantry staple. Oats are a good source of complex carbohydrates and both soluble and insoluble fiber, containing more protein and natural fat than other cereal grains. They are also gluten-free, making them an excellent option for people with gluten intolerance or celiac disease. However, there are a few things you may want to consider when choosing the kind of oats you want to cook.

1. 1. Consider cooking times. The more processed the oats are, the quicker they will cook. Instant oats cook the fastest, while whole oat groats cook the slowest. Rolled oats typically cook quicker than steel-cut oats, which need to absorb lots of liquid to reach an edible texture.
   
2. 2. Different oats suit different dishes. Different types of oats are better suited for different uses. For example, rolled oats are better for oatmeal cookies, granola bars, or granola. Quick oats or Scottish oats are best to make fine, silky porridge, and steel-cut oats are best for chewy porridge.
3. 3. Consider the health benefits. While there are slight differences in the amount of fiber or protein in different forms of oats, the difference is so small as to be irrelevant. All forms of oats make for a healthy breakfast cereal.
