Oat groats
Oat groats are the whole, minimally processed kernels of oats with only the outer husk removed. Unlike rolled oats or quick oats, oat groats retain their natural bran, germ, and endosperm, giving them a pleasantly chewy texture and a rich, nutty flavor. When cooked, they create a hearty and satisfying porridge that feels wholesome and nourishing, making them an excellent choice for breakfast, meal prep, or healthy side dishes.
One of the biggest benefits of cooking with oat groats is their impressive nutritional profile. They are rich in dietary fiber, particularly beta-glucan, which may help support heart health and maintain healthy cholesterol levels. Oat groats also provide complex carbohydrates for sustained energy, along with important nutrients such as protein, iron, magnesium, zinc, and B vitamins. Because they are less processed than other oat products, they digest more slowly, helping you feel fuller for longer and supporting stable blood sugar levels. Their versatility, nutritional value, and naturally satisfying texture make oat groats a wonderful addition to a balanced diet.
Overnight cooking:
This apple porridge using oat groats needs slow, long cooking. If you cook your porridge the night before, you will have it ready and warm in the morning!
I have an old AGA cooker, so I use the simmering oven for slow overnight cooking. But a slow cooker can be used to make this porridge.
Ingredients
- 1/2 cup of oat groats
- 2 apples
- 2 handfuls of raisins
- Cinnamon
- Sea salt
How to prepare the porridge
Soak the oat groats with a drop of lemon juice or apple cider vinegar for 8 hours.
Rinse the oat groats and put them in a small saucepan; a good stainless steel saucepan or a small cast-iron is best.

Cut the apples into small pieces, and put them in the saucepan with the oats.
Add the raisins.

If cooking in a cast-iron range, add 2 1/2 cups of water to the saucepan with the oats, apples, and raisins, and add a pinch of salt and the cinnamon. Cover and bring to a boil, then put in the Simmering Oven and leave overnight.
In a slow cooker, add 2 cups of water, the oats, apples, and raisins, and a pinch of salt and cinnamon. Set it to low

In the morning, you will have the delicious porridge ready to eat.
