Oats & Oat Flour Recipes: Safe for Celiac and Gluten-Sensitivity?
Oats on their own are gluten free. But not all oats are certified gluten free because of cross contamination in production. Meaning those with celiac disease need to watch the labels to ensure the brand is certified gluten free.
How to Make Oat Flour
Oats are easy to make into oat flour
All you need is a blender or food processor and viola, you have oat flour. Grind it longer for more fine flour and shorter for a coarser blend. I don’t normally grind my own flour, but oat flour, I do.
Toasted oats bring out the flavor
Toasting the oats beforehand is not necessary to make oat flour, but it sure does bring out the deep, robust flavor of the oats. It’s a lot like toasting nuts – if you’ve ever had a toasted walnut, they have that darker and more intense flavor than an untoasted walnut.
Oats produce a nicely balanced bread
Oats are high in protein and fiber, but just how high and what does that mean for bread baking? Well, according to our flour guide, oat flour contains about 17% protein and 10% fiber. Compare that to brown rice flour that has 7.5% protein and 5% fiber and almond flour with 21% protein and 10.7% fiber.
Both of these are key factors in how much water the flour will absorb during mixing. The oat flour with a higher protein and fiber count will absorb more water than the rice flour, but the almond flour will absorb more than the oat flour. Oat flour is an excellent choice for yeast breads as it it a nice balance.
Ingredients & Substitutions in this Oatmeal Bread Recipe
Fortunately, the simple ingredients list for this bread isn't too complicated. You'll want to make sure all ingredients are weighed and at room temperature. For where to purchase these ingredients - I recommend somewhere like Nuts.com where the oats are certified gluten free.
Below are the ingredient brands I use and recommend and the substitutions:
- Gluten free oats - These rolled oats by Bob's Red Mill work wonderfully. If you need to substitute the whole oats, I'd suggest going with a different bread recipe... this sorghum bread is delicious. Oats are a main ingredient in this bread so substituting them changes the whole recipe.
- Tapioca starch (also called tapioca flour) - Use the one from Nuts.com - they are not only budget friendly, but also really high quality. Instead of tapioca starch, you could use cornstarch, potato starch or arrowroot starch as well.
- Almond milk - Here's a great almond milk at a great price (make sure you pick unsweetened!). If you don't want to use almond milk, go for oat milk or coconut milk.
- Oil - I used vegetable oil, but peanut or canola or even melted coconut oil would work well too. I have not tested olive oil.
- Yeast - use the active dry yeast. The recipe has not been tested with instant or quick rise yeast.
- Sugar - regular white, granulated sugar was used in the recipe. A substitution for it would be Swerve sweetener. I use Swerve in this sandwich bread and in these lemon poppy muffins and it works the best of all the artificial sweeteners I've tried. Swerve isn't cheap but this oat flour bread is not a sweet bread, so you just use a small amount of sweetener.
- Honey - there's only a Tablespoon but honey adds such a wonderful flavor to this bread. I used this raw honey. Instead of honey, maple syrup would be an equally great substitute.
- Eggs - So there are 3 eggs in this recipe. I used organic eggs from my local grocery store. But if you need to substitute the eggs, go for chia eggs or flax eggs (my guide to substitutes covers this extensively).
How to Make Gluten-Free Oat Bread
Step 1: Make the oat flour: After toasting the oats, add the oats, tapioca flour and salt to the food processor. Mix for about 4 minutes to make the finely ground flour.
Step 2: After the oats are toasted, add to the bowl of a food processor.
Step 3: Process until a flour forms - about 5 minutes.
Step 4: Add oat flour, salt and tapioca starch to the bowl of a stand mixer.
Step 5: Use a small pot and heat the milk and oil just to a rolling boil.
Step 6: Immediately remove from the heat and pour it into the bowl with the dry ingredients.
Step 7: Mix on medium speed until fully combined. The batter will be very firm and not soft. Let cool for 20 minutes.
Step 8: Meanwhile, stir the yeast into the warm water and let proof for 5 minutes.
Step 9: Add the proofed yeast mixture and the honey to the stiff batter and mix for about 30 seconds on medium.
Step 10: Then add the eggs and mix again for 1 minute. The batter will not look like traditional bread dough. It will be stiff, but not able to be kneaded.
Step 11: Scrape the batter into the prepared baking pan. Use a 10 inch size bread pan or a 9"x5" loaf pan.
Step 12: Cover with a piece of plastic wrap and let it rise just until the top of the batter touches the rim of the pan. This may take anywhere from 15 to 30 minutes.
Step 13: Bake the loaf for about 50 minutes or until an instant read thermometer reads between 205 - 210 F. Start checking it at 45 minutes.
Storing this Healthy Oat Flour Bread
Store this bread in an air tight plastic bag or airtight container for up to 2 days at room temperature. Any longer than that and you'll need to slice it and freeze it. Individual slices may be toasted directly from frozen.
Pro Tips for this Gluten Free Oat Bread Recipe
This loaf has been tested and retested and retested again - it's an absolutely delicious bread with a slightly nutty flavor, but for the best results, it's important to follow these pro baking tips:
1. Use room temperature ingredients
Room temperature ingredients, as opposed to straight from the refrigerator, are a crucial factor in the success of this oat flour bread. It's tempting to just pull that milk straight from the refrigerator and add it to the recipe, but cold ingredients do not mix well and do not make for a nicely risen bread. The same goes for the flours and starches.
Tips for quickly warming eggs: Take a glass measuring cup like this one and fill it ⅔ full of water. Heat the water in the microwave for about 45 seconds. Remove the cup and float the eggs in the warm water for 2-3 minutes. (Watch your water temperature as hotter water will mean the eggs warm faster, less warm water may take a little longer).
2. Measure the flours and starches by weight
As you probably know, gluten free baking is so much different than baking with regular flours. From the use of starches in baking to the multiple flours, everything is different. And so is the way we measure ingredients. Now more than ever, a digital kitchen scale, like this one, is more important in your baking than ever before. You'll want to weigh everything in grams and then keep it exact. I talk about this more in my baking masterclass, but these measurements need to be exact. And cups may be vastly different from cup measure to cup measure.
3. Tools for successful bread
Some of these you may have on hand, but these are the tools you'll need to make this recipe:
- Stand mixer - when I say this is a tool you need, it really is one you need! It's a big purchase for sure, but one that will serve you well for years (and I mean years!) to come. For reference, my Kitchen Aid is 22 years old and works like new.
- Digital scale - there are some pricier scales out there, but this model is the one I have and works just as well as those. You basically want to it to be able to show grams and switch back and forth from ounces, grams, even ml is nice.
- Food processor - I never thought I used this as much as I do, but I realized this handy appliance's importance when my old one when out! I like this one because it's reliable and doesn't break the bank.
- Cookie sheet - something with a non stick coating is as versatile for cookies as it is for toasting these oats.
- Instant read thermometer - how any times has it looked like a loaf of bread is done, only to cut into it and see these gummy slices. Now it's not always a baking issue, but many times, that gumminess is just because the bread isn't fully baked. An instant read thermometer will help remedy that problem. I would recommend something like this one. There are always more expensive ones out there, but this one works great.
- Baking pan - the baking pan you want to use for this bread is one that has dimpled edges so the batter can 'climb' up the walls. These pans are excellent for that reason.
- Rubber spatula - This batter is quite stiff for the first few steps, that's why you'll need a good quality rubber spatula for working with it. These are excellent and seem to last forever!
Gluten Free Oatmeal Bread FAQs
The bread is excellent with just about anything from breakfast with some honey and butter to lunch sandwiches. My personal favorite is a mid afternoon snack with a dab of honey!
The best way to store this bread is to wrap it well or place it into a plastic bag and either freeze it or keep it at room temperature for up to 2 days.
An alternative would be to use a hand mixer like this one.
After mixing together the milk mixture and oat flour mixture, the batter will not be like batter, it will be very stiff. Not until after you mix in the eggs will it look like softer batter.
