I don’t have a microwave. How long should I cook it on the stove?

Thank you

    Hi Susan,
    Sorry for the delay. Do you have a rice cooker? That works great. Otherwise – bring to a boil on the stove, then reduce heat and simmer for 40 min. For overnight, simply bring to a boil, then remove from heat, cover overnight.
    Thanks for the inquiry.

Overnight Oat Groats , my new favorite! Used your recipe (except did all the cooking in the microwave) & it was delicious! Now am “playing around” changing spices, fruit and liquids. FABULOUS!

Can you just soak Oat groats overnight and eat it the next morning? Or do you have to cook it first?

    The best way to do that is just to bring them to a boil first, then cover them overnight. They will be soft, a bit crunchy and delicious in the morning. Check out our recipe for “Crazy Breakfast”. It’s our favorite. Thanks,

      Is it possible to make a granola from oat groats by boiling them first and then bake in over after stirring in maple syrup, honey, nuts and seeds etc? Will it be crunchy enough if baked at about 140-150°C for about 30 minutes?

        Hi Purvi,
        Absolutely. I could them in a rice cooker too. So simple. Then simply add your syrup etc. I think that would work better than baking – as they need a little moisture to soften.
        Thanks for your inquiry.

What is the difference between oat Groats and steel cut oats?

    Deb Wheaton

    Deb Wheaton · April 17, 2018 at 5:31 PM

    The oat groat is the whole seed of the oat plant. Steel cut oats are oat groats that have been cut. Our unique variety of oat groat is very small and looks and cooks just like rice. It is also raw and sproutable too.
    Hope that helps.

We have been eating overnight oats every morning for 3 years.
We buy our oats in 50 pound bags delivered to the door by Amazon and drag the bag to the pantry.
We use a rice cooker and cook for one hour and just keep them in the pot.
Next morning they are cooked and cooled down. We break up the cooked groats .
We add cut up apples or bananas or whatever and add lime juice from one lime.

Now the good parts.
I am a male over 70.
I lost 40 pounds, groats fill you up .

    Hi Tom,
    Sounds delicious. Thanks for sharing. And this is how we prepare our groats too. But I’ve never added lime. I’ll try that. Do you buy our Groats?

I like to soak the Oats overnight. The next morning I blend them in a vitamin with water. Can be eaten raw with cinnamon dates and coconut milk.
