Which Oats Are the Best Buy?

When you make oatmeal, you can choose from the following types of oats:

  • Flaked Oatmeal
  • Oat Groats
  • Steel-Cut Oats

Out of the three types, oat groats will be your best buy.  Oat groats are the whole oat grain that has not been adulterated in any way. Since it has received minimal processing, the cost is lower than the other forms of oats.

So the next time you are out shopping or ordering online, be sure to look for oat groats and add them to your cart.  You will be able to use the oat groats to make a delicious and budget-friendly breakfast that is easy to make.

Making Apple Cider Vinegar

When you soak your oat groats in water overnight, you’ll want to add apple cider vinegar, lemon juice, or whey. I like to use apple cider vinegar.

Did you know you can easily and cheaply make homemade apple cider vinegar? I’ll show you how in my three-part series. You won’t need to buy it from the store anymore!

In addition to soaking oat groats to make soaked oatmeal, you can also soak beans and nuts, as well as sprout flour to make healthy and delicious homemade recipes.

Mockmill also makes an electric grain mill that is a very affordable and beautifully crafted. This German-made mill stone grinds grain with settings ranging from 1 to 10—fine to coarse ground grain.

How to Make Soaked Oatmeal Using Oat Groats

5 from 1 vote
Prep: 5 minutes
Cook: 10 minutes
Soaking time: 12 hours
Total: 12 hours 15 minutes
Yield: 4
Making soaked oatmeal is not only nutritious, it's also very affordable using inexpensive oat groats.


  • 1 cup Oat groats
  • 4 cups Water divided
  • 1 tablespoon Apple cider vinegar
  • 1 teaspoon Sea salt coarse ground
  • 4 ounces Unsalted butter optional
  • 1 tablespoon Cinnamon optional


  • Place the oat groats on a parchment-lined baking sheet and place into a 350°F or 176°C oven to toast for no more than 5 minutes.
  • Remove toasted oat groats and allow to cool. Once cooled, transfer to a small grinder. Grind oat groats to a consistency of half powder and half chopped groats.
  • Add oat groats to a small sauce pan, which is either enameled cast-iron or stainless steel. Cover oat groats with 2 cups of the water. Also add 1 tablespoon of apple cider vinegar. If you do not have apple cider vinegar, you can use lemon juice or whey.
  • Allow oat groats to soak overnight or for approximately 8-12 hours.
  • After soaking, place the saucepan containing the oat groats on the stove burner on medium high and add the remaining water and the salt. Bring the oat groats to a simmer and turn the heat to medium low, continually stirring to prevent the oat groats from sticking to the bottom of the pan.
  • After about 10 minutes, the oat groats should have thickened. Now add the butter and cinnamon, if using, and stir until combined. The oatmeal is now ready to be served.



Toasting the oat groats before grinding enhances their flavor.
Serve up your oatmeal with any combination of a variety of seasonal fruits, chopped nuts and seeds, cream, honey, and maple syrup, or simply served plain.

  1. Hi Mary,
    I love your videos. Would love to try this recipe. Can I use steel cut oats instead of the whole groats. Thank you Joyce

  2. Hi Mary,
    I want to try soaking oatmeal but I can’t have gluten so I’m wondering if you know of any foods with phytase that can replace the rye. I tried google but I didn’t really get any results. The only thing I found was foods with phytic acid. Are you able to help me with this?

    1. Hi Roz,

      Thanks so much for your note. I understand completely. You can leave the rye flour out. Instead just use the Apple cider vinegar. The acidulated water will help significantly to activate the phytase which will help to decrease the phytic acid.

      Hope this helps!

      Please let me know if you have any other questions. I’m so happy to help!

      Love, Mary
