I’m a huge advocate of starting the day with a protein rich breakfast, and my chocolate protein oats and protein overnight oats are always in my rotation! I also love this make ahead berry protein baked oats, which always turns out amazing.
Inspired by that, I thought of making a crockpot oatmeal with old-fashioned oats, and I’m so glad I tried this one out. Everyone in my family absolutely loves it, and now, it's regularly on my meal prep routine too.
Why You’ll Love This Crockpot Oatmeal Recipe
- Low calorie: The oatmeal is sweetened with coconut sugar and is an excellent low calorie breakfast option to make, especially if you're watching your weight.
- Make ahead breakfast: If you love meal prepping, this one's going to be a great addition to the menu. It's great to make over the weekend and enjoy throughout the week.
- Easy to make: It’s a seriously easy, no-fuss recipe to have in your arsenal.
- Healthy and filling: If you love starting your day with a healthy, high protein breakfast, you’ll love this filling recipe.
Ingredients
- Apple: You can use almost any kind of apple here, but I would recommend using a sweet variety like Honeycrisp which helps to naturally sweeten the oatmeal.
- Rolled oats: Rolled oats have the best texture and are chock full of fiber, which makes them the perfect choice for this recipe.
- Applesauce: For a bit of natural sweetness.
- Cranberries: I used frozen cranberries. If you have fresh cranberries, feel free to use them.
- Coconut sugar: To sweeten the oatmeal. I like the coconut sugar because it has a lower glycemic index but feel free to use maple syrup, agave or honey if you prefer.
- Egg whites: Boosts the protein and helps give some structure to the dish. Whole eggs won't give you as much protein so I don't recommend using them.
- Milk: To get the mixture to the right consistency.
- Seeds: I used a mix of pumpkin seeds, chia seeds, and hemp seeds here. These lend the slow cooker oatmeal a nice boost in nutrition, add some texture, and also help thicken the oatmeal by absorbing liquid.
- Flavorings: You’ll also need a dash of vanilla extract for the flavor, and some cinnamon to lend a bit of warmth to the dish.

Variations & Dietary Modifications
- Dairy-free: Swap the milk in the recipe for unsweetened almond milk or any other plant based milk of your choice to make a dairy-free version of this recipe.
- Fruit swap: Swap the apple for pear and use other berries like strawberries, raspberries or blueberries to enjoy a different flavor variation.
- Add nuts: Nuts like pecans, almonds, and walnuts can be a great addition to this crockpot oatmeal recipe.
How to Make Crockpot Oatmeal with Apples and Cranberries
To make this Crockpot protein oatmeal, start by spraying the inside of your Crockpot with some nonstick cooking spray.
Step 1: Whisk eggs and milk. Combine the eggs and milk in a large mixing bowl and whisk together.
Step 2: Add remaining ingredients. Add in all the remaining ingredients.
Step 3: Mix well. Gently mix everything.
Step 4: Transfer to slow cooker. Transfer the oatmeal mixture to the greased slow cooker and cook on low for 3 hours or on high for 1 hour.
Step 5: Finish up and serve. Once the apple and cranberries have softened and the oatmeal is cooked turn off the slow cooker and serve immediately.
Storage Directions
- Storing: Store the leftover baked oatmeal in the refrigerator for up to 4 days, and reheat it in the microwave whenever you want to. Make sure you cover the container with plastic wrap or a lid to seal in the moisture.
- Reheating: You can reheat the oatmeal in the microwave or the oven. Just make sure you don't end up overcooking it, and cover it with a lid to keep it moist.
- Make ahead: Make this crockpot oatmeal in a big batch and portion it out into meal prep containers to store for months. You can then reheat them from frozen, or thaw them overnight in the refrigerator and reheat them in the morning.
Serving Suggestions
You can enjoy this healthy oatmeal hot or cold. Team it up with Greek yogurt for some extra protein or top it with a drizzle of maple syrup and chopped nuts for some sweetness and texture.
I love enjoying a bowl of this oatmeal with my hot chocolate smoothie or low calorie pumpkin spice latte during the colder months of the year. You can also pair it with this carrot cake protein smoothie or a healthy pumpkin smoothie.
Recipe Tips
- Thaw first: If you're using frozen cranberries, remember to thaw them first and then use them for the recipe.
- Bake it: If you don't have a crockpot or just want to bake the oatmeal instead, you can do that too. Portion it out into ramekins or pour the mixture into an oven safe dish and bake at 375 degrees for about 30-45 minutes.
- Adjust the flavors: Feel free to use a bit more vanilla or cinnamon, leave out the sweetener, or add a bit more. There's lots of flexibility to make it to your own tastes.
Recipe FAQs
Technically, you can use instant or quick-cooking oats too, but they don't tend to preserve their texture, and end up turning mushy when you use them for this recipe.
You absolutely can! Use a heavy-bottomed saucepan or pot to cook the oatmeal on a stovetop. Make sure you keep the heat medium-low and stir frequently so that you don't end up burning it. Cook until the fruit reaches the desired consistency and the oats absorb the milk. It should take about 15-20 minutes.

I must totally not be very cool, because I was never even talked to at the gym... I think people just notice how well you do at certain things or your consistency Megan, and they admire that!
I'm actually more of a work out at home gal; it takes bravery for me to go to the gym. O_O
Oh girl, you don't have to look a certain way or even know what you're doing. You just need to show up with the confidence of a rockstar!
How many cups is one serving size?
About 1/2 cup
Haha I'm so terrible at "spacing out" at the gym Dave will often be like did you see so and so (clearly I didn't), so I almost never notice if someone is staring and I don't get many people coming up to me asking questions (prob. bc I'm in beast mode when I'm there lol). I kind of love that! This recipe looks amazing, I still have some frozen cranberries, yum!!
I space out too, but people still do it to me! I think it's because I'm so hard core compared to everyone else.
Oooh, I think that I have all of these ingredients in my kitchen. Making it soon!! I love all of the texture and flavors from the variety of seeds and fruits! No boring oats allowed. 🙂
I can't remember the last time I had a plain bowl of oats. haha!
This looks like such a delicious, comforting breakfast! I love all of that sweetness from the apples and the cinnamon pairs beautifully! Thanks for sharing, Megan! 😀
It is the ultimate winter comfort & nourishment. Thanks Kennedy!
How much do you consider a serving? I always struggle with this.
1/8th of the recipe is one serving. Start by taking 1/2 cup of the mixture and placing in a bowl or container. Repeat this until you have 8 containers then take the remainder and divide equally among the 8 containers. If you're concerned about getting the exact portion, this is the way to do it. You can also weigh the entire cooked oatmeal on a food scale then divide by 8 to get the weight in grams per serving.
HOLY YUMMINESS!!!!!!!!!!!!!!!!! And as for the gym, I rather not say some of the things.. 🙂 I think you are a motivation!!!!!
HAHA...I want to know if this stuff happens to you or if it's just me!
I think it's probably a mix of you being motivational and there being a few freaks out there, haha! But mostly the first one, I'm sure.
This oatmeal sounds delicious! I love that you can wake up and it's ready to eat. My kind of breakfast! 😉
Well, I seem to attract a lot of weirdos in general but I like your theory so I'm going with that. Have a great weekend Sarah!
I've never tried making oatmeal in a crockpot before, but it sounds like a great idea, especially for Sunday food prep!
It is! You really should try it sometime.
Obviously, this look s amazing. I would love to have known what people thought while I was doing the hand bike!
I could tell you what I think of those hand bikes...
That's creepy :/ Another perk or working out with my "home gym" 😉
And I still need to try making oatmeal/porridge in my slow cooker!
I have to say I've been to a lot of gyms and mine is the most normal of any I've been to with the exceptions I mentioned. And yes! You really need to bust out the crockpot and make oatmeal. It's so easy!
I guess that's one of the reasons I avoid the gym - I'd rather just get my workout done without having any social interactions! I go so infrequently that luckily none of that has happened 🙂 And that's pretty cool that you have loads of recipes ready to go! I'm always scrambling to put something together in time.
I think I just attract the freaks. That seems to happen to me everywhere I go. And yes! I have so many recipes sometimes I forget I have them. Haha! I try to keep a list of, but it gets lost with all my other lists.
You had me clicking and sharing with the word meal in the crockpot 🙂 but I have to join in that I'm all about the at home these days. Just don't talk to me 🙂
haha! I don't know what I'd do without my crockpot. It's a lifesaver.
