How Long Do Oats Last?
Unopened oats will last for months—even years—when stored in a cool, dry place like your pantry or cupboard. Once opened, however, they should be used within three to six months for the best quality (1).
You can tell if your oats have gone bad by looking for signs of spoilage such as mold or off-odors. If they smell musty or rancid, it’s best to discard them (2).
Once cooked, oats will last in the fridge for four to five days or in the freezer for two to three months (3).
However, cooked oats may become mushy when reheated so it’s best to eat them within a day or two of cooking.
Storing Oats Properly
To extend the shelf life of unopened oats and keep them fresh for as long as possible, be sure to store them in an airtight container in a cool, dry place (4).
Once opened, transfer them to an airtight container as well and use within three to six months for the best quality.
Can Oatmeal Be Refrigerated And Reheated?
If you’ve ever had oatmeal that’s been refrigerated and reheated, you know it can be a bit gummy and not as tasty as when it’s fresh. But is it safe to eat?
The answer is yes, oatmeal can be refrigerated and reheated without any food safety concerns.
However, there are a few things to keep in mind to make sure your oatmeal is still delicious.
First, when reheating oatmeal, be sure to add a little extra water or milk to help rehydrate the oats and prevent them from getting too thick or gummy. Second, if you’re using pre-cooked oats (such as quick-cooking or instant oats), they will cook more quickly than rolled oats and may not need to be reheated at all – simply add some hot water or milk and they’ll be ready to eat.
Finally, if you find that your reheated oatmeal isn’t as flavorful as you’d like, try adding a little brown sugar, honey, or fruit before eating.
With these tips in mind, there’s no reason why you can’t enjoy delicious oatmeal anytime – even if it’s been refrigerated for a few days!

How Long Does Oatmeal With Milk Last in the Fridge
If you’re like most people, you probably have a box of oatmeal in your pantry and a jug of milk in your fridge. But how long does oatmeal with milk last once you’ve combined them?
The answer depends on a few factors, including the type of oatmeal and milk you’re using, as well as how long the oatmeal has been sitting in the fridge.
Let’s take a closer look:
Type of Oatmeal: Quick-cooking oats will spoil faster than rolled oats or steel-cut oats. This is because quick-cooking oats are more processed and have less fiber than the other types of oats.
Type of Milk: Whole milk will spoil faster than skim milk or almond milk. This is because whole milk contains more fat than skim milk or almond milk. Fat creates an environment where bacteria can flourish, leading to spoiling.
How Long Oatmeal Has Been in the Fridge: If you make a batch of oatmeal and then refrigerate it, it will last longer than if you combine all the ingredients and then refrigerate it. The reason is that when food spoils, bacteria release enzymes that break down carbohydrates into simpler sugars. These simple sugars then act as food for the bacteria, causing them to multiply rapidly.
So, if there are fewer carbohydrates present (as in the case of pre-made oatmeal), there will be less food for the bacteria to thrive on.
Bottom line: If you’re using quick-cooking oats and whole milk, your oatmeal with milk will last 2-3 days in the fridge before spoiling.
How Long Does Cooked Oatmeal Last Out of the Fridge
If you’re like most people, you probably have a container of oatmeal in your pantry. But how long does cooked oatmeal last out of the fridge?
Cooked oatmeal will last for about 3-4 days in the fridge.
After that, it will start to spoil and should be thrown out. cooked oatmeal can be stored in the freezer for up to 6 months.
To extend the shelf life of your cooked oatmeal, make sure to store it in an airtight container.
This will help keep bacteria and mold from growing on your oats.
When it comes to leftovers, always err on the side of caution and throw out anything that looks or smells suspicious. If you’re not sure whether or not your oatmeal is still good, play it safe and toss it out!
