Meal prep is just something that is so helpful for our weeks, especially having little kids.

I’ve always preferred to utilize simple meal prep tips, which I break down in this meal prep for athletes post.

Healthy oatmeal meal prep is part of our weekly to do list because there’s so much you can do with oats!

Baked Oatmeal Meal Prep

Baked oatmeal is one of my favorite forms of meal prep oatmeal because it’s a blank canvas with infinite possibilities!

Whether you want it fruity, savory, sweet, peanut buttery, or something else, there are endless options for your baked oatmeal meal prep.

Skipping breakfast is one of the worst things you can do.

A balanced breakfast is linked to improve cognition, blood sugar control, improved nutrient intake, and less cravings throughout the day!

You can choose different fruits based on the season, you can use dried, fresh or frozen, and you can add fun add in’s, like chocolate chips, nuts, seeds, hemp seeds, spices and more.

You really can’t go wrong with baked oatmeal for your meal prep oatmeal.

Here are some great recipes to get you started.

Baked Oatmeal Meal Prep

These baked oatmeal recipes can help streamline your oatmeal meal prep for the week.

How to Meal Prep Hot Oatmeal

If you don’t enjoy the texture or flavor of baked oatmeal, you can even speed up your morning bowl of hot oats. While it doesn’t take long to cook oatmeal anyway, you have a few options.

You can meal prep your breakfast oatmeal on the stove, in the microwave, or in the crockpot or instant pot.

With these oatmeal breakfast meal prep tips, just keep your ingredients out and pre-mixed and you’re all set for a quick, nutrient-dense morning snack!

When I make my favorite stovetop turmeric oatmeal, I premix the spices the night before, so in the morning I just add oats, milk, spices and banana!

Here’s what you can do to streamline your hot oats:

  • Keep dry oats in a pantry container and pre-measure 1/2 cup-3/4 cup in individual tupperware containers or bags.
  • Then, in the morning, throw in a microwaveable-safe bowl and add a liquid. I usually do 1 cup of liquid for 1/2 cup of dry oats. Microwave for 1-3 minutes, depending on the type of oats and desired consistency.
  • Add your favorite toppings! I always use peanut butter, fruit, nuts and a dollop of greek yogurt.

Overnight Oats Meal Prep

Another method to enjoy the health benefits of oatmeal is overnight oats.

Overnight oats meal prep is perhaps one of the more common ways to meal prep oatmeal and is delicious and refreshing for hot, summer months.

You can use frozen fruit, like those overnight oats with frozen cherries, or fresh or canned fruit.

Meal prepping overnight oats is simple and can be catered to all of your favorites. I love using meal prep oatmeal jars for these.

Overnight oats are great for on the go, too.

Especially if you store them in portable oatmeal jars that you can take in the car, to the gym, to the office, etc. Then, wash and reuse.

Use these tips to streamline your overnight oats recipe meal prep.

  1. Pre-measure your oats – I usually do 1/2-3/4 cup of dry oats. Add to a glass container or mason jar for meal prep oatmeal jars.
  2. Add a liquid – Liquid is necessary for the oats to soak up. I usually use cow’s milk for extra protein, but soy milk or a milk substitute would also work.
  3. Add any add-in’s – Some ideas include fresh or frozen fruit, nuts, seeds, vanilla extract, spices (cinnamon, nutmeg and turmeric all make great toppers!), or cocoa powder. I also always add chia seeds, flax seeds and/or hemp seeds for extra protein and nutrients.
  4. Add a creamy/thickness factor – For me, I love to use greek yogurt, but cottage cheese or a yogurt substitute would work also. This also helps to amplify the protein content in your overnight oats meal prep jars, as well as add probiotics, calcium and Vitamin D – important bone building nutrients. Another option is mashed sweet potato or pumpkin puree.
  5. Shake everything together and cover overnight – When you wake up in the morning, it’s ready to eat. Just grab a spoon and enjoy.

To streamline these, make a bunch at once and have your overnight oats meal prep done in 5-10 minutes of your time.

My favorites are these high protein overnight oats, lemon blueberry overnight oats and cookie dough overnight oats.

Easy Meal Prep Snacks with Oats

Don’t forget about snacks. These meal prep snacks come together quickly thanks to the oats, many of which are healthy no bake snacks.

Snacks are one of my favorite ways to enjoy the health-promoting benefits of oats throughout the day, not just at breakfast!

Health Benefits of Oatmeal

Oatmeal is very nutritious and has several essential vitamins and minerals that honor health. Some of these nutrients include:

  • Fiber – the fiber in oatmeal is great for gut health, and provides prebiotic fiber to diversify the flora and provide fuel for the probiotics (live bacteria). Fiber also helps with satiety and can help reduce cholesterol. There is about 4 grams of fiber per cup of oats.
  • B-Vitamins – B Vitamins, such as folate and B-6, are important for metabolism.
  • Iron – Iron is helpful for so many functions in the body, from oxygen delivery to blood, to cognitive function and immunity. A cup of oats provides about 2 mg of iron. More on iron for runners here.
  • Magnesium – As a whole grain, oatmeal is also a source of magnesium, a mineral that is involved in over 300 reactions in the body.
  • Protein – While oatmeal is not a high protein source, it does provide some protein, about 5 grams per cup.

These micronutrients are important to get in the diet for overall health and oats are a magnificent way to get several of them.

Yes, it’s so easy to add protein sources to oatmeal! You can add nuts/seeds, greek yogurt, cottage cheese, or dairy or soy milk.

Can you add protein powder to oatmeal?

Absolutely! Adding protein powder to oatmeal is so easy. I usually go with a vanilla or chocolate flavor, and you just mix it in your warm bowl of oats overnight oats, or even baked oatmeal.

Can you eat oatmeal from the day before?

If it’s baked oatmeal or overnight oats, absolutely! If it’s hot oatmeal, it may stick together. You could reheat it, but I prefer making leftover oatmeal cookies!

How to store meal prep oats

How to store your oats will depend on which form of oats you’re making. Baked oatmeal can be stored in the fridge for up to 5 days, or frozen for up to 3 months. Overnight oats will keep for 3-5 days in the fridge. Hot oatmeal should usually be enjoyed immediately.
