Blueberry Baked Oatmeal is an easy, healthy breakfast you can prep the night before. Perfect for a stress-free weekday breakfast!

We love oatmeal around here – in baked oatmeal, in overnight oats, in breakfast cookies… I have a few versions of baked oatmeal here on the blog that are super delicious already, but a blueberry one was definitely missing!

This works great with both fresh or frozen blueberries, so it’s a wonderful make ahead breakfast all year round. You can even switch up the berries if you’re feeling adventurous – raspberry is a firm favorite over here, too!

You can prep this the night before for an easy morning, but if you want to bake it right away, I’ve included some instructions below.

Ingredients in baked oatmeal

Here is a visual overview of the ingredients in the recipe. Scroll down to the printable recipe card at the bottom of this post for quantities!

Ingredients you’ll need: Rolled oats, applesauce, eggs, walnuts, vanilla extract, maple syrup, milk, baking powder, cinnamon, salt and blueberries.

Ingredient notes

  • Eggs: Instead of whole eggs, you can also use 3 large egg whites. I have never tried making a vegan version without eggs, so I can’t recommend any substitutions here.
  • Sweetener: Use 1-2 tablespoons of a Stevia or Erythriol blend to sweeten the oatmeal if you want to make it sugar-free.
  • Oats: I always use old fashioned. Quick oats work OK, too, they’re just a little moister. Please do not use instant oats.
  • Blueberries: I always use frozen because they’re more budget-friendly. You can use fresh if you want to.
  • Milk: Cow’s milk or unsweetened almond work best here.

Steps to make baked oatmeal

collage if steps to make blueberry baked oatmeal

Steps to make baked oatmeal with blueberries:

1) Combine all ingredients except for the blueberries in a large bowl.

2) Spread half in a lightly greased casserole dish and sprinkle with ¾ of the blueberries.

3) Cover with the remaining oat mixture, then

4) sprinkle with remaining blueberries and more walnuts if desired.

5) Chill covered in the fridge overnight, then bake in the morning.

Recipe tips

  • No grey oatmeal: I usually don’t stir the blueberries into the oats, but but sprinkle them on top, to keep the oatmeal from turning all weirdly grey.
  • Bake without soaking overnight: Make sure to use quick-cooking oats, let the assembled oats sit on the counter for 10 minutes while you preheat the oven, and live with the fact that it’s a little less cake-like 😉

Serving suggestions

Some of my family members prefer theirs in a bowl with milk and use a spoon to eat their oatmeal.

Others like it cake-style, with a few spoonfuls of Greek yogurt and a fork. And one particular tiny person might like it best cold, slathered with peanut butter 😉

I let them do whatever they want, as long as they get their own stuff and put it back again after breakfast, ha!

Large step by step photos

I just use a large bowl, measure out all my ingredients, dump them in the bowl and stir with a wooden spoon until they’re combined. Well, that’s pretty much the recipe 😉

oat mix for blueberry baked oatmeal

I’m using a 7×11 rectangular baking dish. You could also do individual muffin cups! I prefer layering my baked oatmeal vs stirring the blueberries into the whole mix. This a) helps prevent blueberries sticking to the bottom of the baking dish like glue and b) doesn’t turn your baked oatmeal a ghastly grey color.

First, I spread half the oat mix in the bottom of the baking dish. It’s smart to just lightly grease the dish, but I often forget. Then I layer on most of the blueberries.

THEN I add the rest of the oat mixture…

… and scatter with a few remaining blueberries and some extra chopped walnuts for pretty looks. This is not necessary, but it does look nice.

This is what it looks like after an overnight rest IN THE REFRIGERATOR:

Then you just pop it in the oven and pat yourself on the back for being so organized 😉

    I just made this (my first ever attempt or taste of baked oatmeal). I used quick oats, brown sugar and an equal amount of mashed banana instead of the applesauce. Plus fresh blueberries. It tastes AMAZING. I ate TWO pieces straight out of the oven. Love it

    This was delicious…my hubby even liked it! The consistency of the oat blend was a tad runny, so I added in some ground flaxseed and that did the trick. Thank you for the great recipe…will be added to our recipe lineup.

    Is this ok to freeze?

      June 27, 2022 at 12:29 pm

      Yep, totally! Freeze wrapped in plastic wrap, then aluminium foil for up to 3 months. I recommend defrosting overnight for best results, but you could just defrost it in the microwave. I like mine warmed up, so I either use my steam oven or the microwave to re-heat. Hope this helps!

      No, it’s actually better to use them straight from the freezer. Hope this helps, Heather!

    Fantastic recipe! I have made it as-written with the blueberries and LOVE it. One day, much to my horror, I was OUT of blueberries and in the middle of making the recipe. I instead cut up 2 cups of small diced apples and they too were a perfect replacement for the tastes of cinnamon and walnuts. I love to drizzle just a little maple syrup on top when serving. Oh and sometimes I add 1/4 cup ground flaxseed which also was great. Thank you for an easy, delicious, flexible, and nutritious recipe! 🙂

    Love this recipe. Not to sweet so if you tend to like sweet things more you might add a little extra syrup. Bet some toasted coconut would be good too. I used just old fashioned oats, not instant and only let it sit 30 minute not over night. I give it 4 stars! Easy to make and quick.

    *****I just made this recipe last week and I have enjoyed your delicious oatmeal all week long. It is the perfect breakfast especially on a cold winter morning. I like the fact that you can dress it up to your specific liking. I can also say that it stays with you all morning, no need for mid morning munchies. I am going to make another batch again right now. Thanks for the recipe!!!

    My husband and I love this recipe for so many reasons, but especially for its versatility! The second time we made it, we swapped the apple sauce for two bananas to achieve the sweetness level we prefer; we had just enough blueberries for the top only. This dish is so quick to prepare the night before, then we just pop it in the oven in the morning to have with coffee and eggs. So delicious!
