Overnight oats are perfect for a busy morning. They’re ready to go when you need them, so you get out the door quickly.

This chia seed oatmeal is even more filling than regular oatmeal. The chia seeds expand in your stomach, making you feel full for longer. I love to have this breakfast when I know I have a busy morning ahead of me.

This is a basic recipe for chia overnight oats, and it can be dressed up with some add-ins in the morning. I like to add raspberries, strawberries, and bananas along with walnuts or almonds. A drizzle of peanut butter and a few coconut flakes are delicious, too.

Step Four: Cover the chia seed oatmeal and refrigerate

Put a lid on each container, and place the covered containers in the fridge overnight. In the morning, top with berries, nuts, or any other desired toppings. Serve cold or warm.

This recipe serves four, and it generates fairly large servings. You can divide the oatmeal into smaller jars if you don’t have a big appetite in the morning.

Chia Seed Oatmeal Tips and Frequently Asked Questions

Should I soak chia seeds before adding to oatmeal?

It isn’t necessary to soak the chia seeds. They quickly absorb the liquid from the oatmeal mixture, and they add a nice bit of texture to the oatmeal.

Can I make this oatmeal on the stove?

This recipe is for overnight oats, but you can make chia seed oatmeal with regular stove top oatmeal, too. I like to cook the oats according to the package directions, then stir in the chia seeds. Let them soak into the oatmeal while it cools.

What are the best oats to use for overnight oats?

I like to use old-fashioned rolled oats for this recipe, but quick oats are steel cut oats could be used as well. I prefer to cook the oatmeal when using steel cut oats.

What are the best toppings for chia seed oatmeal?

You can add any of your favorite toppings. Some combinations include raspberries and blueberries, bananas and mini chocolate chips, and strawberries, pecans, and shredded coconut. Drizzle with a bit of extra sweetener such as pure maple syrup, honey, or agave nectar if desired. But if you’re adding banana to the chia seed oatmeal in the morning, you can skip the extra sweetener. A ripe banana will sufficiently sweeten the oats.

    I have some sprouted rolled oats , can I add it straight to the recipe or does it need to be cooked ?, look forward to exploring and trying out more of your recipes, in efforts of healthy eating with toddler twins

    1. I haven’t made this with sprouted rolled oats, but I imagine it would be fine to use them in this recipe without cooking. Please let me know if you try it.
