Overnight Oats

Jump to Recipe Print Recipe

This simple, satisfying overnight oats recipe is the perfect solution if you often find yourself short on time in the mornings. It takes mere minutes to throw together, and your refrigerator does the hard work for you!

While I often turn to my tried and true Instant Pot Steel Cut Oats recipe, overnight oats work for me when I just want to meal-prep and not have to think about planning breakfast for a few days. It’s also a smart option for warmer weather, when you may not necessarily want a hot breakfast.

One of the things that first drew me to overnight oats was the texture — something magical happens when you mix oats and milk, and pop it into the fridge overnight. You end up with a thick, creamy, luxurious mixture that you can flavor any way you like! (And I have plenty of ideas for you below.) My basic overnight oats recipe can also be flavored with any of your favorite toppings or mix-ins.

So if you’ve spent too many mornings rushing out of the house with a rumbling tummy while chugging a cup of coffee, consider trying these grab-and-go overnight oats.

What You Need to Make This Recipe

Ingredients needed to make overnight oats.

Base Oats Recipe

Old-fashioned rolled oats — old-fashioned oats are the best option for making overnight oats. They absorb liquid really well, so you end up with a thick mixture when it’s time to chow down. Steel-cut oats, quick oats, or instant oats don’t absorb liquid quite as well, so steer clear of those for this recipe.

Milk — any milk will do. I chose to use oat milk, but dairy milk or non-dairy milk (almond milk, coconut milk, soy milk, cashew milk, etc.) will work as well.
Plain yogurt — While this is optional, I think it amps up the creaminess of the oats, as well as adding a subtle tang. But you can skip it and use more milk instead. You can also use an equal amount of Greek yogurt.

Maple syrup — a tablespoon of maple syrup adds a bit of sweetness. You can also use honey, agave nectar, or other sweeteners of choice. You could also ditch the sweeteners altogether and rely on your mix-ins for a little sweetness instead (more on that below).

Chia seeds — another optional ingredient, chia seeds are a nutritional powerhouse that I like adding to my breakfast oats for an extra boost. They’re a good source of protein, fiber, and fatty acids. Chia seeds also absorb liquid really easily, so they’re a good way to make sure you end up with thick, almost chia pudding-esque overnight oats, with no excess liquid.

Salt — a small pinch of salt brings out all the other flavors in this overnight oats recipe.
You can stick with the ingredients above for delicious oats, but if you’re looking for more flavor and different textures, keep reading for a few simple add-ins that will take your breakfast to the next level.

Chocolate Chip Peanut Butter Overnight Oats

Chocolate chips — I like semi-sweet chocolate chips as they aren’t too sweet. Feel free to use whatever kind of chocolate chips you like, whether they lie on the sweeter or more bitter ends of the spectrum.

Peanut butter — who doesn’t love chocolate and peanut butter? But beyond the addictive flavor combo, peanut butter is a great source of protein, so you can start the day off on the right foot. Other nut butters are delicious here too, like almond butter and cashew butter.

Berry Overnight Oats

Berries — simply mash up some of your favorite berries and toss them in! I went with blueberries, but strawberries, raspberries, and blackberries would taste great!

Vanilla extract — vanilla lends this recipe a bit of a dessert-like flavor that complements the berries.

PB & Jelly Overnight Oats

Fruit jam — use your favorite fruit jam, be it strawberry, blueberry, plum, peach…really, whatever you like!

Peanut butter — you can use either creamy or chunky peanut butter.

Strawberries — diced strawberries are optional, but they add a pop of bright color, a little tartess, and textural interest to the recipe.

Banana Nut Overnight Oats

Banana — you’ll need ½ a banana, mashed up with a fork.

Nuts — chop up some nuts of your choice. Whatever you have on hand will be perfect for a little crunch.

Shredded coconut — if you’re a fan of some subtle coconut flavor, you’ll love this! Shredded coconut also absorbs liquid well, so it will help to thicken up your overnight oats.

Nut butter — try peanut butter or almond butter.

Ground cinnamon — a small amount of ground cinnamon rounds out all the flavors in this breakfast recipe.

5. To give your breakfast a PB&J sandwich sort of twist, Add your chosen fruit jam and peanut butter to the container. If you like fresh fruit in your oats, dice up some strawberries and toss those in, too.

6. If you like banana nut muffins, you’ll love these add-ins! Mash up a banana well with a fork. Chop up a couple of tablespoons of nuts and add them to the oats, along with an equal amount of shredded coconut. Add peanut or almond butter, and ground cinnamon. Add the mashed banana and mix everything together.

Once your extras have been added, close the Mason jar and refrigerate overnight. The next morning, you may need to add a little milk to thin it out, but otherwise, it is ready to enjoy

Pro Tips for Making This Recipe

For best results, use old-fashioned oats. Steel-cut, instant, and quick-cooking oats don’t absorb liquid as well as rolled oats.
To up the protein ante, add a scoop of protein powder to the jar along with the oats. You may need to add a little more liquid to compensate for the extra dry ingredient, but it’s a great way to add a protein boost to your breakfast.
Go nuts with toppings! No, really. Chopped nuts are a delightful topping for this recipe because they add crunch and texture. Another crunchy option is granola. Or you can add sliced fresh fruit, chocolate chips, and drizzles of nut butter.
Refrigerate the oats overnight. The oats need a lot of time to absorb all the liquid and become thick and creamy.
If your oats have thickened up more than you expected, add a little milk to thin it out. Start with a tablespoon at a time until you have the desired consistency. Be careful of adding too much milk or you will end up with runny oats.

Frequently Asked Questions

How long do they last?

Overnight oats are a great make-ahead option as they will keep well in the refrigerator for five days.

How do I store leftovers?

This recipe yields a single serving, but if you have leftovers, simply close the jar and pop it back into the refrigerator.

Can I freeze them?

Yes! You can make the base recipe and freeze it after refrigerating overnight. Fruits, spices, and other mix-ins can change their texture and flavor after being frozen, and freezing the plain oats avoids that issue. Just add your flavorings once you’ve thawed the oats.

You can freeze single servings in freezer-safe jars or containers. Or, spoon the oats into silicone muffin cups, freeze, and pop them out and store in freezer bags.
They will keep for up to 3 months. Thaw the oats in the refrigerator for 12-24 hours before eating.
