The Best Overnight Oats Base Recipe

Great overnight oats are creamy, not gluey. They taste balanced, not bland. The best jars also hold up well in the fridge. Once you learn this basic formula, you can make overnight oats every week. Use this base once, then change the flavor each day.

Use this as your base formula for 1 serving:

• 1/2 cup rolled oats, the base, gives structure and chew

• 1/2 cup milk, our liquid of choice that softens the oats and adds creaminess

• 1/4 cup Greek yogurt, adds body, tang, and protein

• 1 tablespoon chia seeds, to thickens the mixture

• 1 tablespoon maple syrup, for sweetness

Optional, but helpful for flavor:

• 1/4 teaspoon vanilla extract

• Pinch of cinnamon

• Tiny pinch of salt, this boosts flavor fast

If you like your overnight oats thinner , add a splash more milk in the morning. If you prefer  thicker oats, add a little bit more chia seeds. If you want to do a big batch, just double each of the ingredients,

How to Make Overnight Oats – step by Step

I love how easy it is to make overnight oats. Once you have the base formula down, you can do it with your eyes closed all week.

Step 1, Mix the base

Add the base ingredients to a jar or bowl:

• Rolled oats

• Milk

• Greek yogurt

• Chia seeds

• Maple syrup

Then stir very well. Make sure the chia seeds are fully mixed in. They like to clump if they sit in one spot.

Tip, if you are making a flavor variation, add the mix-ins now [like cinnamon, cocoa, mashed banana, or nut butter].

Step 2, Let it rest briefly, then stir again

Let the mixture sit for 2 to 3 minutes, then stir again. This helps to distribute chia seeds and keeps the texture smooth.

Step 3, Cover and chill

Cover the jar or bowl and place it in the fridge.

• Minimum soak time, 2 hours

• Best soak time, overnight [about 8 hours]

Allow the mixture to chill overnight gives the oats the best texture. This way you get turn creamy, thick, and fully hydrated overnight oats

Step 4, Stir and check the texture in the morning

Give the oats a quick stir before serving. If your overnight oats are too thick, add a splash of milk. If too thin, stir and let it sit a few more minutes

Step 5, Add toppings and serve

Add toppings right before serving for the best texture.

Good topping ideas include:

• Fresh fruit

• Nut butter

• Chopped nuts

• Seeds

• Coconut flakes

• Granola [for crunch]

Keep crunchy toppings  such as granola separate until morning so they stay crisp.

Can you eat overnight oats warm?

Yes, you can. Many people eat overnight oats cold, but you can warm them if you want a cozier breakfast.

Quick warming tip:

• Microwave in a microwave safe bowl or jar [if safe], in short bursts

• Stir between each burst

• Add a splash of milk if needed

The oats may thicken more when heated, so a little extra milk helps.
