What Kind of Oats Can You Put in a Protein Shake?

4 min read

Over 75% of Americans eat breakfast, and a growing number are adding oats to their protein shakes for a more substantial meal. Knowing what kind of oats can you put in a protein shake is key to achieving the desired texture, from ultra-smooth to satisfyingly thick and hearty.

Quick Summary

Different types of oats impact the texture of a protein shake, with rolled oats and quick oats blending the smoothest when used raw. Steel-cut oats are coarser and require soaking or grinding for the best results, while oat flour offers the most seamless integration. The right oats provide complex carbs, fiber, and micronutrients for a more balanced and filling drink.

Key Points

  • Rolled Oats: Use old-fashioned rolled oats for a versatile option that blends to a creamy texture with a little chew; soaking them first helps achieve a smoother consistency.

  • Quick Oats: Opt for quick oats if a super smooth, grit-free protein shake is your priority, as they are thinner and blend the easiest.

  • Steel-Cut Oats: Avoid using raw steel-cut oats directly in shakes due to their coarse, chewy nature; for best results, cook and cool them or grind them into a powder first.

  • Use a High-Speed Blender: For all oat types, a powerful blender is key to breaking down the fibers and creating a consistent, smooth drink.

  • Nutritional Boost: Adding oats to your shake provides sustained energy from complex carbs, boosts fiber intake for digestion, and adds essential vitamins and minerals.

  • Control Consistency: Adjust the thickness of your shake by adding more or less liquid, or by pre-blending the oats with the liquid before adding other ingredients.

Adding oats to a protein shake is a popular and effective way to boost its nutritional value, transforming a simple beverage into a hearty meal replacement or a powerful pre-workout fuel. The type of oat you choose, however, significantly affects the final texture and your blending process. Understanding these differences allows you to customize your shake for optimal taste and consistency.

The Three Main Types of Oats for Shakes

Not all oats are created equal, especially when it comes to blending into a smooth beverage. Here is a breakdown of the most common types and how they perform in a protein shake.

Rolled Oats

Also known as old-fashioned oats, these are oat groats that have been steamed and flattened. They are a popular choice for shakes due to their versatility and moderate processing.

  • Benefits: Provide a good balance of chewiness and smoothness. They blend well, especially if given a few minutes to soak in the liquid beforehand, which helps soften them and reduce graininess.
  • How to Use: Add them directly to the blender with your liquid and protein powder. For a smoother texture, consider blending the oats and liquid first before adding other ingredients.

Quick Oats

These oats are rolled thinner and processed further than rolled oats, which allows them to cook much faster.

  • Benefits: Their finer texture makes them the easiest to blend, resulting in an exceptionally smooth shake without much effort. Quick oats are a perfect option for those who dislike any graininess in their drink.
  • How to Use: Because they absorb liquid so readily, they can be blended directly into your shake without any pre-soaking.

Steel-Cut Oats

Also known as Irish or pinhead oats, these are whole oat groats chopped into smaller pieces. They are the least processed type, giving them a chewier, heartier texture.

  • Drawbacks: Because of their thick, unprocessed nature, steel-cut oats do not blend easily when raw and can leave your shake with a very coarse, unappealingly chewy texture. You should not add these directly to a shake unless you want a very crunchy result.
  • How to Use: If you want to use steel-cut oats, it is best to cook them first, then chill before adding to your shake, or grind them into a powder in a coffee grinder or high-speed blender before adding them.

Comparison of Oat Types for Protein Shakes

Feature Rolled Oats Quick Oats Steel-Cut Oats Oat Flour (Ground Oats)
Processing Steamed and flattened Rolled thinner than rolled oats Chopped oat groats, least processed Ground into fine powder
Texture in Shake Creamy with slight chewiness Very smooth and velvety Coarse and very chewy (if raw) Seamlessly integrated
Best For... Balanced texture, meal replacement Smooth consistency, quick shakes Cooked or pre-ground for thickness Invisible addition, baking
Preparation No pre-blending or soaking needed, but can be helpful for smoothness No special prep needed Cooked and cooled or pre-ground Ready to blend immediately
Fiber Content High Slightly less than rolled High High

How to Achieve the Perfect Texture

The preparation method can be just as important as the type of oats you choose. For the best results, consider these tips:

  • Use a high-speed blender: This is particularly important for breaking down denser oats like rolled oats to ensure a smooth, grit-free result.
  • Soak your oats: If using rolled oats, soaking them for 10-20 minutes in your liquid base before blending will soften them dramatically, resulting in a silkier shake.
  • Blend the oats first: A common strategy for a smoother finish is to add just the oats and liquid to the blender first. Blend until the oats are fully pulverized into a flour-like consistency before adding your protein powder and other ingredients.
  • Add enough liquid: Oats thicken your shake considerably. Don't be afraid to add extra milk or water to reach your desired drinkable consistency. Thicker shakes can serve as more filling meal replacements.
  • Experiment with oat flour: For the absolute smoothest finish, use oat flour directly. You can buy it pre-made or create your own by grinding rolled oats in a high-speed blender or coffee grinder.

The Nutritional Advantage of Adding Oats

Beyond texture, adding oats significantly enhances the nutritional profile of your shake. Oats provide complex carbohydrates, fiber, vitamins, and minerals that contribute to your overall health and fitness goals.

  • Sustained Energy: The complex carbohydrates in oats digest slowly, providing a steady release of energy that prevents a blood sugar spike and subsequent crash. This is ideal for a long-lasting pre-workout energy boost or a filling breakfast.
  • High in Fiber: Oats are rich in soluble fiber, especially beta-glucan, which has been shown to help lower cholesterol and improve heart health. Fiber also aids digestion and keeps you feeling fuller for longer, helping with weight management.
  • Micronutrients: Oats contain essential micronutrients like magnesium, zinc, and B vitamins, which support various bodily functions, from energy production to immune health.

Conclusion: Choosing Your Best Oat Type

The best oats for your protein shake depend on your personal preferences for texture and convenience. If a silky-smooth shake is your top priority, quick oats or oat flour are your best bet. For a more balanced, slightly heartier texture, rolled oats are an excellent choice, especially if you blend them thoroughly. Steel-cut oats are best reserved for a hot bowl of oatmeal unless you are willing to pre-process them. No matter your choice, adding oats is a simple, effective way to turn a basic protein shake into a more nutritionally complete, energy-sustaining meal that supports your fitness and health goals.

Frequently Asked Questions

Yes, it is perfectly safe to put raw rolled or quick oats in a protein shake. They are processed through steaming and are safe to consume without cooking. Raw steel-cut oats, however, are very hard and should be cooked or finely ground before adding.

Quick oats or oat flour provide the smoothest texture in a protein shake because they are the most processed and finely ground. Rolled oats can also be blended very smoothly, especially if you pre-soak them or blend them first with the liquid.

You do not need to pre-grind rolled or quick oats, as a good blender can handle them raw. However, grinding them into a fine powder (oat flour) before adding will guarantee an even smoother, less grainy texture.

Start with 1 to 2 tablespoons of oats and adjust according to your preference for thickness and calorie goals. For a more substantial, meal-replacement shake, you can add up to half a cup.

Adding oats provides slow-digesting complex carbohydrates for sustained energy, boosts dietary fiber for better digestion, and adds valuable micronutrients like magnesium and zinc. It also thickens the shake and makes it more filling.

Oats will definitely make your shake thicker and creamier. If you prefer a thinner consistency, simply use less oats or add more liquid to the mixture.

While technically possible, using raw steel-cut oats is not recommended as they do not blend well and will leave your shake coarse and chewy. The best way to incorporate them is to cook them beforehand or grind them into a powder.
