Gluten free whole oats vs quick oats, many people can enjoy both on a gluten free diet plus steel cut oats and oat flour. It’s great to have so many options but there are a few things you need to know about oats.

Before you learn about safe oats it’s important to know that some people with celiac disease simply don’t tolerate oats. That includes safe gluten free oats. If you’re not completely symptom free on a gluten free diet you might need to pay attention to what you’re eating that contains oats. With the recent introduction of gluten free Oreos there has been a lot of discussion about them because they contain oat flour.

This is just a reminder that learning is an important part of a gluten free lifestyle. It’s not enough to simply look for the certified gluten free symbol. You need to keep up on food manufacturing if you want to be as healthy as possible.


Before we get into whole oats vs quick oats, we need to address BROW. When you’re new to the gluten free lifestyle you learn about the acronym BROW. It stands for barley, rye, oats and wheat and they’re all off limits. With oats in that list you can see that many things aren’t as simple as the advice you got to “just avoid gluten.”

Barley, rye, oats and wheat have traditionally been grown, transported and processed in close proximity. So although oats themselves don’t contain gluten they are considered unsafe because of the way they’re produced. That is until some farmers and manufacturers decided to change that.

Reliable Sources and Understanding the Purity Protocol

Manufacturers have been trying to be helpful with terms like certified to test to less than 5ppm of gluten or processed in pure oat dedicated plant. Now we finally see clear symbols on products saying certified gluten free. Yipee! You still need to know what that means in the country the product was made in but there’s no arguing these symbols have made life easier for gluten free shoppers.

As a general rule I say don’t get your medical information on Facebook but it would be more accurate to say look for credible sources. Here are some places I look to for reliable up-to-date information.

Cooking With Whole Oats vs Quick Oats

Whole Grain Rolled Oats

Also called large flake oats these are my favourite! I can make hot oatmeal for breakfast in the winter and use them for baking too. They’re a staple in my pantry and here are a few more ways I like to use them.

  • In my chewy Granola Bars
  • For homemade granola to help create those big clumps I like.
  • In Uncooked Dainties, a favourite childhood cookie in my family, large oats and coconut are what make the messy haystack look I want.
  • Large flake oatmeal is my choice for that crunchy topping on a Fruit Crisp or as part of the streusel topping I sometimes use on muffins.
  • A British tradition and a good tip for gluten free cooks in to substitute oat flakes for breadcrumbs in meatballs or meat loaf.
  • If I specifically need oat flour or just want a small amount of flour I can whiz up some whole oats in my food processor and make oat flour.

Quick Oats

These are small flake oats that cook more quickly. Whole oats cook in the microwave for two minutes while quick oats only take 1½ minutes. I eat hot oatmeal for breakfast in the winter but I prefer the texture of whole oats for oatmeal. If you like quick oats then I just saved you 30 seconds every time you make oatmeal.

I could list just as many uses or quick oats as whole oats so they really are interchangeable. You decide on the texture you like and what kinds of things you make in your kitchen. Of course you can buy both but I try to minimize the number of items in my pantry so I stick with whole oats.

Steel Cut Oats

Some people love the texture and nutty flavour of steel cut oats. If that’s sounds like you then by all means try them. My husband likes to cook them on the stove for 25 minutes and might add grated apple or applesauce to mix things up. A pinch of cinnamon it nice too.

I’m more likely to cook whole oats for 2 minutes in the microwave and be done with breakfast.

Oat Flour

Safe oat flour is now easy to find if you want to experiment with another flour. Try it in all things oatmeal. To learn more about using oat flour check out this post from my yearlong blog series, How To Use Oat Flour.

So it’s not gluten free whole oats vs quick oats, it’s more how many oat products do I want in my pantry. I’d love to hear your take on oats in the comments below.
