Fermented oatmeal is a delicious and traditional breakfast. It’s as quick as instant oatmeal, but far cheaper and healthier than store-bought instant oatmeal packets. Stir in some nutritious and probiotic toppings to really kick-start your day!
Why Ferment oatmeal?
Pre-soaking and fermenting grains before cooking is a traditional way of preparing them. Some of the benefits include:
- Reduced cooking time – rolled oats will cook in the same amount of time as quick oats
- Improved digestion – complex carbs are broken down before cooking.
- Healthier – breaking down phytic acid increases the absorption of nutrients.
- Flavour development – fermented oatmeal has a delicious sourdough flavour.
Probiotic Toppings For Oatmeal
It’s easy to add delicious and nutritious flavours to your oatmeal. Stir in flax, chia seeds, hemp hearts or walnuts. Add fresh berries, chopped apple or raisins. Cook your oatmeal with pumpkin pie spice, chai spice or straight cinnamon. However, for a delicious probiotic oatmeal, top it with a dose of probiotics. Here are a few delicious suggestions:
- Cultured Dairy: Yogurt or buttermilk are perfect for oatmeal. I don’t recommend pouring milk kefir into hot bowl of porridge because it tends to curdle.
- Cultured Coconut Milk: Thick and creamy coconut milk yogurt is delicious with sliced banana, kiwi and pineapple.
- Fermented Fruit Sauce: Try a spoonful of fermented apple sauce or berry sauce with a sprinkling of hemp hearts and cinnamon.
- Caramel Sauce: If you’re a sweet tooth, switch up your usual sweet toppings for a probiotic date caramel sauce.
- Naturally Sweet Condiments: Instead of jam, try a naturally sweet fermented condiment, like apple chutney, mostarda or cranberry sauce.

- Prep Time: 2 minutes
- Cook Time: 10 minutes
- Total Time: 12 minutes
- Yield: 2 servings 1x
- Category: Breakfast
- Method: Fermented
- Cuisine: Traditional
Ingredients
- 1 cup rolled oats
- 2 tbsp culture (see notes)
- 1 cup water (chlorine free for soaking)
- 1 cup of water for cooking
Instructions
- Mix the oats with the culture and 1 cup of water in a glass container.
- Cover with a tea towel and leave to ferment in a warm location overnight or for up to 2 days.
- To cook, boil 1 cup of water and mix into the oats. If it’s not warm enough you can cook the oats for a few minutes in the microwave or on the stove top.
Notes
- Usually, I make fermented oatmeal with milk kefir. You could also use other dairy cultures like buttermilk and yogurt.
- For vegan oatmeal, culture with vegan yogurt or kombucha.
- The kitchen counter is fine for soaked oatmeal. However, if you want a strong sourdough flavour, then stash your fermenting oats somewhere warm, like above your refrigerator, near a heater, or beside your hot water tank.

Emillie, does one have to use a starter culture? Will the oats ferment on their own without the inclusion of any culture?
★★★★★
Oats will fermented without a starter (like sourdough), however it will probably take about 5 days. I usually set up my oatmeal the night before with a starter because I’m not that organized!
I put organic yogurt & the liquid with my oats & water overnight and eat them straight out of the jar (not cooking) is that okay? Especially in summer time, I’d rather not cook them. Is it more or less beneficial cooking or eating raw. I add blueberries, nuts, seeds and a little almond creamer to sweeten. Just wondering what you opinion is about eating them ‘raw’
★★★★★
Fermenting the oats for raw eating is definitely better than just eating raw oats with milk (muesli style.) If it doesn’t bother you, then I don’t think you need to have it cooked, especially as having it raw will give you a good dose of probiotics.
