If you're a fan of oatmeal and cozy, warm fall flavors, then you'll love these pumpkin pie overnight oats.

If you've never had overnight oats you might be wondering what they are. And if you know, you know.

Basically, overnight oats are delicious, creamy oats made by soaking the oats overnight in liquid - a no-cook method for making oats.

So instead of hovering over the stovetop to prevent your oats from burning the bottom of your favorite pot, or blitzing your oats in the microwave, you just mix and let it sit. The oats soak up the liquid and all of the flavorful additions and become soft and creamy.

For these oats, we're adding big flavor, because without big flavor what's the point?! I love oats and overnight oats, but they do need just a little encouragement in the flavor department. Luckily, my pumpkin pie overnight oats are full of flavor boosts from pumpkin puree, coconut sugar, coconut milk, vanilla extract, and my homemade Pumpkin Pie Spice Mix.

The bottom line is that all you have to do is mix this up and let it sit. Come back in the morning to your ready-made breakfast. Give it a stir and then serve it up.

Ingredients

About the ingredients for this recipe. See the recipe card below for exact amounts.

• the oats: For my overnight oats recipes I prefer to use half old-fashioned rolled oats and half large flake oats. Most recipes I've read use all old-fashioned oats for a super creamy texture. I like my oats to still have a bit of texture, a bit of chew. Just don't use quick oats, they'll get too soft.
• the liquid: I prefer to use plant milk for my oats, but you can use cow's milk or even water. For this recipe, I use coconut milk because I like how it combines with the pumpkin puree and pumpkin pie spice to create a rich flavor. For a sweetener, I usually use either coconut sugar, brown sugar, or maple syrup. You could also use honey.
• the flavor boosts: for this recipe you'll need pumpkin puree - make sure not to buy pumpkin pie mix, just pumpkin puree. Pumpkin pie spice adds a warm and cozy flavor. I have a super easy pumpkin pie spice mix recipe, but you can use store-bought if you prefer. You'll also add a touch of vanilla extract.
• other ingredients: Chia seeds make overnight creamy and contribute protein, fiber, and healthy fats. Flax seeds also give healthy fats and fiber. You can skip both of these if you want to but decrease the liquid by about a quarter cup because chia seeds soak up liquid.

TIP: Oats have great nutrition benefits - they are high in protein and fiber and help you feel full and satisfied.

How to Make Pumpkin Pie Overnight Oats

Overnight oats containers

When preparing overnight oats you usually make 2-4 servings at a time - the perfect meal prep recipe! When mixing the oats, you have two options for storage in the fridge:

One large container: you can make all of the servings of oats in one bowl, mix everything together, and refrigerate them like that. When you're ready to eat them, just scoop out the number of portions you need. This makes mixing easier and eliminates the need for small jars with lids. You can use any bowl with a lid or cover it with plastic wrap.
Individual containers: if you want grab-and-go containers, you can mix the oats mixture up and then portion it into jars and then refrigerate them. When you're ready to eat the oats, just grab one portion and it's ready to eat or toss it in your bag to take on the go.

Mixing the overnight oats

In a medium bowl, mix together the oats, chia seeds, flax seeds, coconut sugar, the pumpkin pie spice mix, and a pinch of salt.

Pour the can of coconut milk into a bowl or a 4-cup glass measuring cup.  Fill the cup up to 3 ⅔ cups with cold water.   Add the pumpkin puree and the vanilla extract and whisk until smooth.

Add the wet to the dry ingredients and mix well.

At this point, you can add a lid or wrap it and refrigerate, or you can portion it into 4 smaller containers. Let it sit overnight or for at least 4 hours. Stir before serving.

How to serve overnight oats

You have a couple of options when serving overnight oats.

To serve overnight oats cold: If you made them in a large container just portion out the amount you want into a bowl and eat it like that. Or if you made it in the individual jars just eat it out of the jar, or take it with you if you're going out and bring a spoon with you.
To serve overnight oats warm: If you made the oats in the large container then portion some out into a bowl to microwave it. You can also put some in a non-stick pot to warm it. If it starts to get drier you can add more liquid, like milk. Serve warm.
Serve the oats garnished: You can garnish your overnight oats when you serve them with whatever goes with the flavor of your oats. Use garnishes like fresh fruit, nuts, seeds, nut butter, jam or spreads, coconut, chocolate, whipped cream or coconut cream, spices, granola, or flavored syrups.

RECIPE TIP: If you're taking your oats to go and want to garnish them, don't forget to pack the garnish separately so that you can add it when you're ready to eat.

How do I store overnight oats?

Store your overnight oats in the fridge until serving. Overnight oats last in the fridge for about 5 days or so, making them a great meal prep recipe.
