What are overnight oats?

Overnight oats (aka overnight oatmeal recipes) combine oats, a liquid and a sweetener together to create oatmeal slowly during the night. Mix the overnight oatmeal ingredients the night before so you have a ready-made, transportable oatmeal for breakfast by the morning.

Ingredients for Overnight Oatmeal

• Yogurt: Basically any kind of yogurt works here: plain, nonfat, Greek, Icelandic and even flavored yogurt (although it will affect the taste of the overnight oatmeal).
• Old-fashioned oats: When grabbing oats at the store, double-check the label for “old-fashioned oats” or “rolled oats” (they’re the same thing). Oat packages tend to look exactly alike, and this one tiny detail can make or break your overnight oatmeal.
• Milk: While we recommend fat-free, you can use any type of milk here, even a dairy-free milk alternative.
• Honey: Check out our list of the best store-bought honey brands, as recommended by our Test Kitchen cooks. Substitute maple syrup or agave nectar for the honey if desired.
• Fruit: Use your favorite fruits as a topping. We love to use berries in our overnight oatmeal recipe, just be sure to wash the berries properly without making them soggy.
• Walnuts: You can really use any nut here, just make sure to toast the nuts to remove any raw flavors and bitterness.

Overnight Oatmeal Tips

Taste of Home

Can you use another type of oat?

Do not use another type of oat for overnight oatmeal. Old-fashioned oats have the perfect thickness for the amount of liquid in this recipe. Other types (like quick oats) are too thin and won’t soak up as much liquid, leaving you with runny overnight oatmeal. Thicker oats (like steel-cut) need a lot more liquid than old-fashioned oats and will end up very hard if used in this recipe.

Can you heat up overnight oatmeal after soaking the oats?

You sure can! Place the soaked oats in a saucepan and heat on the stovetop. Or, transfer them to a microwave-safe bowl and nuke them until heated through, about 60 seconds.

How can you make overnight oatmeal creamier?

To make your overnight oatmeal creamier, add an additional tablespoon of yogurt before soaking the oats.

Why are the oats still hard after soaking?

If your oats are still hard after soaking, your ratio may be off. Try not to add more or less of any one ingredient. You may have also used a thicker oat than old-fashioned oats. Double-check your oat container to make sure it says “old-fashioned oats” or “rolled oats”—it’s the same oat with two different names. Any other name means it wasn’t the right oat. Additionally, check to see if your oatmeal has chia or flax seeds, which also soak and gelatinize. They may have stolen some soaking liquid from the oats.

Can you make overnight oatmeal in one large batch instead of individual containers?

Yes, great idea! Multiply this recipe for how many overnight oatmeal servings you’d like to make, and mix it all together in a bowl. From here, you can either divide the mixture into containers or keep the mixture in the bowl. If you do the latter, cover it with storage wrap, keep it in the fridge for up to a week and portion out as much as you’d like when the craving strikes.

Do you add the toppings before or after soaking?

That fully depends on which toppings you’re using and how long they’ll be on the oatmeal. Cut apples and bananas will oxidize, so add those only when you’re ready to enjoy your overnight oatmeal. Any other toppings can be added beforehand, but we don’t recommend keeping toppings like berries on the oatmeal for more than three days as it can speed up their ripening process more quickly than when stored separately.
