I love having oatmeal for breakfast because it’s an easy way to make a breakfast that will keep me full until I have time for lunch. I normally just make oatmeal in the microwave, but lately I’ve loved the simplicity of overnight oats! Soaking the oats in milk helps them soften and after a few hours (or overnight) the oats become thick and creamy.

How to Make Overnight Oats

Add the oats, almond milk, chia seeds, maple syrup, and peanut butter to a jar. Stir until well combined, to ensure that the oats are completely submerged in the milk. Let the oats sit in the fridge for 2-3 hours or overnight. You can enjoy them cold or heat them in the microwave for warm oatmeal.

What are chia seeds?

Yes, chia seeds are the same chia seeds found on chia pets. But they’re actually a superfood! They’re packed with fiber, protein, healthy fats, calcium, manganese, and magnesium. When mixed with a liquid, they expand and thicken. They create a puddling-like texture in these overnight oats. You can typically find chia seeds in the organic section of the grocery store near flax seeds and other seeds. You can also order chia seeds on Amazon.

Chia Seed Substitutions

If you don’t have chia seeds, you can still make delicious overnight oats! You can either substitute the chia seeds for ground flaxseeds, which create a similar thick texture. Or you can add yogurt to create a creamy consistency. I like using 1/4 cup of Greek yogurt for a thick, satisfying texture. To keep this recipe vegan, you can use dairy-free yogurt.

Frequently Asked Questions

  • Do I have to soak my oats overnight? No, the oats will be ready after just a few hours. But they can be soaked overnight, so you can make the oats in advance if you like.
  • Can I warm them up? Absolutely! If you like your oats warm, simply pop them in the microwave for a minute or two to warm them up.
  • Can I skip the sugar? I recommend some sort of sweetener for the best flavor. I’ve made these oats with stevia and I like the taste. You could also use monk fruit or whatever alternative sweetener you like. I recommend adjusting the amount to taste, as it doesn’t measure the same as maple syrup.
  • Can I add other toppings? Yes! Try it with chopped strawberries, raspberries, or a sprinkle of granola. You can also make these oats with almond butter or cashew butter.
  • Can I add more protein? For a high protein recipe, try my cottage cheese overnight oats!
  • What if I don’t have a jar? You can use any container. I recommend a glass container like a mason jar or a small glass container with a tight fitting lid like a Pyrex container. You can also repurpose containers like glass yogurt containers or spaghetti sauce jars! I recommend using a container that is at least 16 ounces so you have room to stir the ingredients together.
