Oat Groats

From the Culinate Kitchen collection by
Serves 3 to 4


Years ago, when we ran the Whole-Grain Challenge on Culinate, James posted his method of cooking oat groats. Who knew there would be such a hullabaloo about groats! I decided to give them a try when I learned that they reheat beautifully. A pot of oatmeal made with rolled oats yields mushy, lumpy leftovers. A pot of cooked oat groats, however, makes for several days of delicious, “instant” oatmeal.


1 cup oat groats
3 cups water
½ tsp. cinnamon
1 apple, grated (with peel)
~ Milk
~ Brown sugar


  1. Place 1 cup oat groats in a saucepan with 3 cups water. Cover the pan, cook over medium heat, and turn off the heat just before it starts to boil. Leave on the stove, covered, until morning.
  2. In the morning, remove the cover and add ½ tsp. cinnamon and one grated apple. Cook over medium heat, simmering the groats for about 15 minutes. Turn off the heat and steam, covered, for 10 minutes.
  3. Serve with milk and brown sugar.

Ten minutes in a pressure cooker with 1/4 tsp salt yields perfect, delicious al dente groats with a minimum of fuss.

Carrie, by “oat groats” do you mean whole hulled oats, as James did, or cracked oats--that is, Irish or Scottish oatmeal? Also, how do you prefer to reheat the groats, if they are to be eaten over several days?

Whole hulled oats are what I call oat groats. They look like wheat berries (and smell like oatmeal cookies when cooking). I reheat them in the microwave: I put a big spoonful in a microwave-safe bowl, cover it with a paper towel, then hit “quick minute.” I think they taste just as good reheated as freshly cooked. If I were to reheat them on the stove, I’d probably cook them over low heat with a little milk or water in a small saucepan.

Funny, I just did a piece on oat groats for The Full Yield! I too use a pressure cooker - they’re delicious with honey and raisins and cinnamon or with butter,
salt and pepper as a side dish, and you can eat from a batch all week long if you like. And you can add the groats to pancakes and muffins. I find oats the friendliest of grains.

I toast the oat groats first, as explained in this post

6. by Deborah Madison on Mar 12, 2012 at 7:04 AM PDT

What a good idea, Simona. I’m going to try that, too, not only with oats but with other grains. How lucky you have a grain CSA - Loved your post on this, too.

Definitely use it on other grains too, Deborah. I always toast whole-grain barley this way and I recently tried rye. Also quinoa acquires a nice flavor when toasted.

I’ve just made a most delicious smoothie. Take a handful of oats groats and toast them till they stop ‘popping’ in a dry pan. Then in your blender add almond milk, a handful of curly kale (about 2 leaves), quarter of an avocado, a banana, fruit of your choice (I used blueberries, but raspberries, mango, pineapple would all be delicious), 1 tsp of almond butter and your toasted oats groats and whizz till smooth. I’ll leave you to work out how much milk, depending on how thick you like it, and equally what proportions of fruit etc. It’s totally delicious, and the toasted oats groats gives it a slightly chewy texture and nutty taste. It’s completely divine!

What an interesting combination of ingredients, Amanda!

10. by Deborah Madison on May 21, 2013 at 11:34 AM PDT

Amanda- that sounds like a terrific smoothie - I’m going to try it. Do you use
a blender or a vita mix? Just curious. I have a hard time with kale in the blender.

11. by anonymous on May 21, 2013 at 12:23 PM PDT

Hi Deborah, I use an old blender and I must admit it takes a while but the kale does disappear into the liquid eventually. I tend not to put the very big bits of stalk in, just the leafy part. If you use plenty of almond milk, and juicy fruit, it should ‘catch’ and liquidise eventually. A vita mix is on my ‘dream’ list!
Hope you enjoy it

12. by Deborah Madison on May 21, 2013 at 2:11 PM PDT

Thank you so much! A Vita-Mix is on my list too, but I’ll just do it longer.
Otherwise it sort of films your teeth I find -

I just bought a 5lb bag of oat groats and had no idea what to do. The recipe that James offered worked perfectly! I skipped the apple and cinnamon, and it was still delicious. It was better than any bowl of oatmeal that I’ve ever had. Thanks!

14. by Deborah Madison on Aug 14, 2013 at 12:20 PM PDT

Lori - Oat groats are also good with butter, salt and pepper for dinner. So chewy and nice - a friendly grain. (And cooked groats can go right into pancakes and muffins or you can add them to other, smaller cereal grains for breakfast.

15. by anonymous on Dec 10, 2013 at 10:22 AM PST

I have great luck with oat groats! I just rinse them, put them in a large pot (usually 4 cups at a time), add twice as much water, and let them sit overnight or all day. Then I just heat the mixture til they start to boil and turn off the heat. As they cool, they absorb the water and turn out perfectly. I freeze half and put the other half in the fridge for several easy breakfasts.

This is a great technique. I toasted the oats, too and found the times to be right on.
