What's the difference between rolled oats and extra thick rolled oats?

3 min read

Over 50% of the world's oats are grown for human consumption, but not all oats are created equal. The primary difference between rolled oats and extra thick rolled oats lies in their processing and thickness, which fundamentally impacts their texture, cook time, and suitability for various recipes.

Quick Summary

This guide explains the distinct properties of rolled oats and extra thick rolled oats, including their processing, textural differences, cooking times, and ideal applications, helping you select the right type for your culinary needs.

Key Points

  • Processing and Thickness: The main distinction is that extra thick rolled oats are rolled less and flatter than regular rolled oats, resulting in thicker, denser flakes.

  • Cooking Time and Texture: Regular rolled oats cook faster (5–10 mins) and become creamy and soft, while extra thick oats take longer (15–20 mins) and remain chewier.

  • Best for Hearty Dishes: Extra thick rolled oats are ideal for overnight oats and robust porridge where you want the oats to retain a significant, chewy bite.

  • Versatile for Baking: Regular rolled oats work well in most baked goods, like cookies and muffins, while extra thick oats provide a more rustic texture.

  • Sustained Fullness: The slower digestion of extra thick rolled oats can promote a greater feeling of satiety and sustained energy, which is beneficial for weight management.

  • Similar Nutritional Profile: Despite the physical differences, the underlying nutritional value—including fiber, protein, and antioxidants—is very similar between the two oat types.

Understanding the Oat Rolling Process

Before diving into the specifics, it's helpful to understand how oats become 'rolled.' Both regular and extra thick rolled oats begin their life as oat groats—the whole oat grain with the hull removed. To prepare them for consumption and rolling, the groats are steamed to make them pliable. Afterward, they are passed through large rollers, which flatten the grain into the familiar flake shape. The key distinction between the two types lies in the final stage of this process: the amount of pressure applied and how thinly they are rolled.

The Standard Rolled Oat

Also known as old-fashioned oats, these are the culinary workhorse found in most pantries. After being steamed, the oat groats are rolled relatively thinly. This process creates a flake that is both firm and absorbent, making it versatile for many applications. When cooked, these oats offer a classic, creamy consistency with a slight chew, perfect for everyday oatmeal.

The Extra Thick Rolled Oat

For a more substantial texture, extra thick rolled oats are the answer. These groats are subjected to less pressure during the rolling process, resulting in a significantly thicker, more robust flake. The less-processed nature and greater density of these flakes yield a noticeably chewier, heartier finished product. This characteristic makes them a favorite for those who prefer more bite and substance in their oat-based meals.

Key Differences at a Glance

To highlight the contrasts, here's a detailed comparison of rolled oats and extra thick rolled oats across several key areas.

Feature Rolled Oats (Old-Fashioned) Extra Thick Rolled Oats
Processing Steamed and rolled thinner Steamed and rolled thicker; less processing
Appearance Wider, thinner, flatter flakes Larger, thicker, more robust flakes
Cooked Texture Creamy and soft with a slight chew Chewy and hearty with more toothsome bite
Cooking Time Approximately 5–10 minutes on stovetop Approximately 15–20 minutes on stovetop
Liquid Absorption Absorbs liquid readily, creating a soft consistency Slower absorption, resulting in a firmer texture
Ideal Uses Oatmeal, cookies, muffins, granola Overnight oats, hearty porridge, textured baked goods
Recipe Substitution Often interchangeable with quick oats with adjustments Cannot directly substitute for thinner oats without affecting texture

Beyond Texture: Taste and Nutritional Profile

While the nutritional content of a plain serving of either oat type is virtually identical, their texture affects how we perceive and feel after eating them. The denser, thicker flakes of extra thick rolled oats take longer to break down during digestion. This slower digestion process contributes to a feeling of greater fullness, or satiety, for a longer period. As a result, some people prefer them for weight management or sustained energy throughout the morning. Additionally, some enthusiasts report that extra thick oats have a nuttier, richer flavor, a result of their more robust structure.

Cooking and Recipe Considerations

Choosing between these two types often comes down to the desired final result. For a classic, creamy oatmeal, regular rolled oats are the traditional choice. They can also be used in most baked goods, providing a pleasant chew without being overly dense. However, if you are making overnight oats or a robust porridge, extra thick rolled oats are the superior option, as they hold their shape and chewiness without becoming mushy. They are also excellent for recipes that demand a more significant, textured grain, such as certain breads or chewier cookies.

The Versatility of Oats

Regardless of the type, oats remain a powerhouse of nutrition, rich in essential vitamins, minerals, and antioxidants. They are particularly known for their high content of beta-glucan, a soluble fiber that has been shown to help lower cholesterol and regulate blood sugar levels. This makes both regular and extra thick rolled oats a healthy choice for breakfast or for incorporating into other dishes.

Conclusion

In summary, the core difference between rolled oats and extra thick rolled oats is the thickness of the flakes, which dictates cooking time and texture. Standard rolled oats deliver a creamy, softer texture, ideal for everyday oatmeal and many baking recipes. Extra thick rolled oats provide a heartier, chewier bite and are best for dishes where a substantial, toothsome texture is desired, like robust porridge or overnight oats. Nutritionally, they are nearly identical, so your choice depends entirely on your texture preference and intended culinary application.

Frequently Asked Questions

Yes, you can use extra thick rolled oats for baking cookies. However, they will produce a chewier, heartier, and more textured cookie compared to using regular rolled oats.

Nutritionally, both types of oats are nearly identical, containing similar amounts of calories, fiber, and protein. The primary differences lie in processing, cooking time, and texture, not overall nutritional value.

On the stovetop, extra thick rolled oats typically require a longer cooking time of about 15 to 20 minutes to become tender, compared to the 5 to 10 minutes for regular rolled oats.

Extra thick rolled oats are a great choice for overnight oats because their robust texture helps them retain a satisfying chewiness and prevents them from becoming too mushy after soaking.

You can, but it will significantly change the final product's texture. For creamy dishes, regular oats are best, while for a heartier, chewier result, extra thick are preferable. Never substitute for instant oats in baking.

The thicker flakes of extra thick rolled oats require a longer time to be digested by the body. This slower digestive process leads to a prolonged feeling of fullness, which can help manage appetite.

While both have a classic oat flavor, some people find that the denser extra thick rolled oats have a richer, nuttier, and more robust taste compared to the more standard flavor of regular rolled oats.
