Whether it’s a lazy weekend brunch or quick weeknight brinner, we’ve got you covered with this Healthy Mixed Berry Baked Oatmeal.

This post was created in partnership with our friends at Kalona Supernatural. 

A small white plate holds a serving of Mixed Berry Baked Oatmeal topped with whipped cream and sprinkled with nuts.

An easy one-bowl recipe that comes together with just a few wholesome ingredients.

Mixed Berry Baked Oatmeal is made with ingredients you may just have on hand. You’ll appreciate that it takes just 15 minutes (or less) to prep and in the oven, it goes. I personally prefer baked oatmeal over a bowl of oatmeal and that is because of the texture and how all of the delicious flavors come together. It’s sweetened ever so slightly with pure maple syrup and in combination with cinnamon, vanilla, and mixed berries it’s truly something scrumptious. I like to serve it warm, right out of the oven, with a dollop of whipped topping or yogurt on top!  You’ll be mmm’ing at every bite.

Mixed Berry Baked Oatmeal is a dish to enjoy all year round.

This recipe calls for frozen berries, therefore it’s perfect to make all year one. I also want to note that it makes for a great meal prep recipe because it reheats nicely and you can even enjoy it cold if time is not on your favor and you need something quick. If you have another kind of frozen berries kickin’ around in your freezer, by all means, save yourself a trip to the grocery store and use what you have on hand.

Kalona Supernatural Organic Plain Kefir is being poured from a glass measuring cup into a bowl filled with rolled oats to make Mixed Berry Baked Oatmeal.

You may have thought that kefir was just for drinking but it’s also great for baking. Whole milk kefir adds richness to baked goods and can be used in place of buttermilk in pancakes, waffles, muffins, and more. I love the flavor and nutritional benefits kefir adds to this recipe and I highly recommend you make it as the recipe calls, however, if needed feel free to substitute any milk of your choosing.

You can learn all about Kefir, what it is, and its benefits in our blog post, What Is Kefir?

In the background, a bottle of Kalona Supernatural Organic Plain Kefir is positioned next to another serving of Mixed Berry Baked Oatmeal.

It’s time to give this satisfying and nutrient-rich Mixed Berry Baked Oatmeal a try!

I can’t wait for you to serve yourself up a piece of this baked oatmeal.

And if you’re looking for additional recipes that call for Kefir, try our Peanut Butter Banana Overnight Oats, Pumpkin Pie Overnight Oats or for something savory our Sweet Potato Nachos.

Tip!

How to Make this Baked Oatmeal Egg-Free

To make this baked oatmeal egg-free, simply replace the egg(s) with ‘flax eggs’ in the recipe and bake as directed.

To make a ‘flax egg’, combine 1 tablespoon ground flax meal and 3 tablespoons water in a small bowl. Stir well and let stand 5-10 minutes to thicken then add to the recipe in place of the eggs.

Double this if the recipe calls for 2 eggs.

    Delicious! I have made it a few times. Once I subbed Greek vanilla yogurt 3/4 cup and 3/4 cup water because I ran out of kefir. it baked up the same, maybe a little sweeter, but still amazing.
