Single-Serve Baked Oatmeal Jars

One of the first recipes I ever blogged about was baked oatmeal. Before my site crashed, I had an awesome post about how to make a fast, easy, healthy breakfast that tasted great on its own or could be fancied up with different ingredients.

Although I don’t have that recipe anymore, I do have a new one that I might love even more. Check out these single-serve baked oatmeal jars.

Easy Portion Control

With this recipe, I don’t have to make a huge batch of baked oatmeal that I eat all week. Instead, I just make one jar that’s perfect for me.

It has all the taste and texture of traditional baked oatmeal but in a manageable sized mason jar or ramekin dish* that you can keep in the fridge overnight and then microwave in the morning. No need to clean extra dishes or preheat the oven.

And just like the original recipe, once you’ve got the basics down, you can mix and match ingredients to create the baked oatmeal that’s just right for you.

Did You Try It?

I love making single-serve baked oatmeal jars when I know I’ll have a busy morning. Even without the protein powder, it’s high in protein and fiber and definitely keeps me full for a lot of my day.

But I’d love to know what you think of it.

Do you have other ingredients that you like to add to your oatmeal? Do you leave out the chia seeds or the peanut butter? Let me know in the comments below. Or, feel free to shoot me a message through my contact me page. I check my email regularly, and I will get back with you as soon as I am able.
