The best part?

The procedure to prepare overnight oats is pretty straightforward. And when you follow the preparation method we mention right below, you also make it safer to eat and preserve.

Just soak the oats at room temperature for about 4 hours before tossing the container in the refrigerator. That’s it!

Soaking the oats at room temp or a slightly warmer than room temperature before refrigeration actually gives you a better nutritional profile by allowing the growth of some beneficial microorganisms.

And refrigeration after the 4-hour mark will slow down the fermentation and keep the oats from getting spoilt.

Eat the overnight refrigerated oats with the toppings of your choice the next day or days after, given you refrigerate or freeze the soaked oats properly. More on this later.

All in all, overnight oats are a nutritious food to incorporate into your overall diet as long as you keep the toppings and mix-ins in accordance with your health goals.

Here’s a complete breakdown of how you are actually supposed to eat overnight oats to maximize nutrition.

Are Overnight Oats Safe to Eat

Overnight oats are uncooked oats that have been soaked overnight or longer in a liquid of your choice.

How long do overnight oats need to sit? 

Allow about 12 hours of overnight soaking altogether. This will reduce the phytic acid content in oats, making it easier for you to utilize the maximum nutrients the next morning.

When it comes to the liquid used to soak the whole grain oats, you have a lot of possibilities. 

Milk, soy milk, nut milk (almond, cashew), water, coconut milk, and hemp milk are all popular options.

Though, overnight oats with yogurt deserve a special mention here.

Many people are keen on trying fermented oats soaked in yogurt overnight. Well, if you’re doing this solely to reduce the phytic acid, you’re better off soaking your oats in just plain water.


According to Monica Reinagel, a US-based nutritionist, while lactobacillus bacteria and acidic mediums break down phytic acid, calcium can block the enzymatic breakdown of phytic acid. Details are available here.

She also mentions that mineral deficiencies caused due to too much phytic acid is primarily a concern for those with nutritionally deficient diets, and it’s not something everyone should worry about.


What About Fermented Overnight Oats?

Well, in order to ferment your oats outside the fridge, you’ll have to submerge and leave them soaked at room temp or warm liquid for 12 to 24 hours.

However, this duration largely depends on the room temperature.

There’s a chance that you may end up leaving the soaked oats out for far too long without the proper knowledge of fermentation and the required temperature, which might make the oats inedible.

Furthermore, you can cook it after leaving it out for fermentation, but then that will defeat the purpose of overnight oats.

That’s the reason it’s advisable to not leave out oats soaking at room temperature for more than 5 hours before refrigeration. This way you will slow down the speed of fermenting the grains and prevent bacterial overgrowth.

Moreover, lemon or apple cider-flavored overnight oats are savory choices if you tend to favor the sour and tangy taste of fermented overnight oats. You can also use yogurt or kefir for a flavorful addition.

Moving on to the choice of oats, steel-cut oats, rolled oats, and quick oats are the three most popular types of oats available.

However, rolled oats are the ideal sort for making overnight oats because they are healthier and produce better results when soaked.

So, yes, overnight oats are safe to eat when prepared this way.

Overnight oats are, in fact, a healthy meal prep option. Whole grain oats are the main ingredient, and they carry a multitude of health benefits. 

Here are five good reasons why overnight oats are safe to eat and can benefit your health immensely:

  • The Improved Digestibility of Overnight Oats 
  • Increased Resistance in Overnight Oats Starch
  • Overnight Oats is Easy to Use in a Variety of Recipes
  • Overnight Oats Save Time and Money 
  • Oats Kept Overnight Taste Great

Moreover, it’s completely a treat to eat if the raw dry oats have been properly hydrated and soaked for at least 12 hours. 

Bonus! Soaking oats also aid in digestion, making it more suitable for gluten intolerant people.

Well, a single search for “Are overnight oats safe Reddit” will likely return a number of results from people who have been enjoying overnight oats.

The best part is there are a number of ways to make your delicious bowl, and most of them fit into a busy schedule.


What is the Best Way to Make Overnight Oats?

Combining four ingredients in a jar or bowl and letting the mixture sit overnight in the fridge is all it takes to make this quick breakfast. 

What is the Best Way to Make Overnight Oats

The following is a list of the ingredients you’ll need: 

#1. Overnight Oats Soaking 

Basic Overnight oats are traditionally made with old-fashioned (rolled) oats. Quick oats or instant oats should not be used since the texture will be unpleasant. 

Make this recipe with steel-cut or rolled oats, which have a considerably chewier texture. Soak the oats for at least 12 hours, though.

Note: Overnight oats phytic acid can be reduced by soaking oats overnight.

Proper soaking can help in the reduction of phytic acid by activating phytase (a type of enzyme). By neutralizing the anti-nutrient, you can aid mineral absorption. And as the phytic acid is broken down enzymatically, there’s no harm in consuming the liquid you soaked the oats in.

#2. Solvent Used

You can use whichever milk you choose. Dairy, almond milk, soy milk, coconut milk, pea milk, and cashew milk are all good options.

We don’t recommend using water if the flavor and creaminess of the oats are essential for you.

#3. Sweetener

Sweeten your overnight oats with pure maple syrup. Honey, brown sugar or coconut sugar can also be used. To make a sugar-free breakfast, reduce the amount of sweetener or leave it out entirely.

#4. Extracts

Vanilla Extract is the secret ingredient, and we strongly advise you to not leave it out!

Just a smidgeon of vanilla extract added to overnight oats before soaking them overnight makes a tremendous change in flavor. The essence offers a hint of vanilla for mild sweetness.

#5. Optional Add-Ons

You can use only the ingredients listed above, or you can add more to your jar of oats. To prepare overnight oats with yogurt, whisk in some high-protein Greek yogurt. 

Almond butter or peanut butter are also excellent sources of protein. For added nourishment, add chia seeds, flax seeds, or hemp seeds.

#6. Toppings

Add your favorite toppings in the morning and enjoy! 

Fresh berries, sliced bananas, or peaches are all good options. Almonds, pecans, walnuts, pepitas, chia seeds, and sunflower seeds, for example, add a delightful crunch. One of the favorite toppings for many is toasted coconut.

A Special Note:

Take a minute to see which toppings will jell with overnight oats. You might be better off adding dried fruits and chia seeds instead of fresh fruits at the time of refrigeration. Plus, you can always add fruits, nuts, or other toppings of your choice before eating the overnight oats.

Normally, the overnight oats expiration date is after four days, making them a wonderful alternative for meal prep breakfasts. 


What is the Best Time to Eat Overnight Oats?

There’s no need to exclude overnight oats entirely from your diet. They can, in fact, be a nutritious and filling part of a balanced diet. 

It’s all in the timing, though. The ideal time to take carbohydrates is later in the day, which goes against the classic rule of breakfast.

The thing is a carb-rich breakfast can easily go overboard in its amount of glucose. And all the glucose that’s left to be used up as energy often gets stored as fat. 

Thus, it’s probably ideal to have a balanced breakfast with protein and healthy fats along with carbs.

So, if you do eat overnight oats as breakfast, add in some protein in there as well.

Or, if you think you can have overnight oats any time of the day, having them at times other than breakfast is also an option.

Eating overnight oats for dinner may sound unusual, but they’re a delicious, safe, and healthful dinner choice. If you’re going to eat overnight oats, it’s ideal to do it around four hours before bedtime to get the most benefit.


Are Overnight Oats Good for Weight Loss?

One of the best sources of resistant starch is overnight soaked oats. Oatmeal has a number of advantages, including the ability to burn abdominal fat. 

This form of starch takes a long time to digest. As a result, you will feel more satisfied and have fewer hunger pangs.

Furthermore, oats activate the release of several digestive acids that reduce appetite and increase the calorie-burning rate.

As a result, overnight oats are safe to eat when combined with healthy add ons and can undoubtedly assist you in losing weight.


Benefits of Overnight Oats When Cooked the Right Way?

This portion of the blog will discuss some of the advantages of overnight oats when cooked right:

#1. You’ll Be in a Better Frame of Mind

The gut bacteria then ferment the fiber, which aids in the creation of a healthy gut environment. And, thanks to the gut-brain axis, a healthy stomach leads to a better mood.

#2. You’ll Be More Consistent

You’ll be able to go to the bathroom with ease thanks to the fiber content in overnight oats—as long as you don’t have any other underlying concerns.

#3. You’ll Feel Fuller for Longer

The satiating quality of overnight oats—due in part to all that fiber—will provide you with enough energy to get you through your morning and avoid the dreaded hunger pangs.

#4. You Might Be Able to Slim Down 

Switching to overnight oats—which contain just about 200-300 calories per half-cup could result in weight loss after a few weeks of sticking to this new routine.

#5. You’ll Improve Your Heart Health 

Switching to overnight oats reduces the number of saturated fats you consume each day, which may help to improve heart health over time.
