When it’s baking, this healthy baked oatmeal fills the kitchen with sweet, cinnamon-y love.

How I healthified this blueberry baked oatmeal

I sweetened and flavored this healthy baked oatmeal recipe with orange juice. And I added some brown sugar, vanilla extract, cinnamon and nutmeg to give this warm dish the aroma and taste that make gathering around the breakfast table something to look forward to. Of course, the coffee and good company are the other two parts of a breakfast or brunch trifecta.

Both the oats and the berries are part of my power food list for prediabetes. Add a third by topping it with some Greek yogurt like I did here, and find out if your yogurt is among the best for prediabetes. These foods are also ideal for the heart and the brain.

    This looks like a really good recipe. If you take out the brown sugar and the orange juice, then on WW (Weight Watchers) “purple” plan, then it would be a “zero point” food (not free). What would happen if I took those two ingredients out? Should I add more fruit? I eat oatmeal every day for breakfast – and usually 2 or 3 eggs (on WW, those are “zero points”). My internist (primary care physician) is glad I lost 50 lbs so far, and he wants me to lose 45 more. I am a 54 year old male. I am on no medications, and my lab results and blood pressure are now normal – with diet and exercise alone!

    Another thing my doctor wants is for me to eliminate “added sugar”. (Note: On WW, eating an orange is “zero points” but a glass of orange juice is 6 points – an orange fills you up more).

    This is a serious question for me since my diet and exercise regimen has done for me what it takes pharmaceuticals to do for many others. Nutrition is powerful medicine.

    Thanks! I may try out this recipe without the orange juice and brown sugar – just let me know what you think.

      Wow, I love hearing about your great success. I’ve made this recipe with milk instead of OJ and it’s quite good. I think you’ll need some sweetener, so I suggest using whatever no calorie or low calorie sweetener you prefer. I’m anxious to hear how your changes work out. I always say that a recipe is a guide, not a contract.

        Hi Jill, as you offered I used the recipe as guide; I dropped the oj, used water, and added nuts, as well as dried apricot. I had no vanilla essence, and ran out of cinnamon, so I topped up with chinese 5 spice and a little cayenne…true confession, wasn’t sure about the size of my egg, so I used 2 and reduced the amount of water.

        From my pov it worked out really well, I lost the sugar, and gained some fibre, and for me the fruit, nuts and spices took away the need for a sweetener of some kind.

        Will definitely be using your recipe again, the eggs and bicarb made the bake lighter than I expected…I think I was expecting something denser like flapjack.

        As you said it is very enjoyable warm with yoghurt; tomorrow I’ll take a piece to work to fill a corner.

        Thank you 🙂

          I LOVE that you did this. And thank you so much for sharing your success. I hope others will take it as inspiration. I sure will. I always say that a recipe is a guide, not a contract.

    Hi, fellow RD here! For those seeking a baked oatmeal that uses less added sugar, I would recommend substituting the OJ with milk, non-dairy milk, or water. And I would limit the sugar to 1 tbsp. I understand the recipe makes 9 squares, which amounts to only 8grams of sugar per serving (not including the OJ), but I’m thinking 1/9 of this recipe might not be filling enough. So people might consume more, upping their added sugar intake. I make a similar baked blueberry oatmeal that uses the same amount of oats, milk instead of OJ, only 20 grams (About 4 tsp) of maple syrup, 2 eggs, some nuts and oil, and it’s sweet enough and filling for my family of 4. It makes 4 large servings at only 4.5 grams of sugar per serving.

      Thanks for these ideas! I’ve made versions with milk, milk and OJ, various and fruits and nuts. All of them turned out great. I like to serve it with Greek yogurt on top. A scrambled egg or two would really round out the meal.

    I love this and usually bake once/week; both myself and my husband are great fans of this. It’s super easy to make and quite filling; I try to eat it mindfully, enjoying the different tastes and textures – thanks!

    • Jill Weisenberger on May 13, 2021 at 9:00 pm

      Yay! This makes me so happy! Have you experimented with the recipe to try other flavors? I’ve done it with other fruit when I didn’t have blueberries.

  4. Denise Grover on April 25, 2022 at 2:05 pm

    Hi Jill, I made this recipe with Almond milk, instead of OJ and used 2 tablespoons of brown sugar to decrease the sugar amount. Since my husband and I are pre diabetic. Can you tell me what the amount of sugar is if you made it following your recipe? just curious. it was great serving it warm with Greek yogurt.

    • Jill Weisenberger on April 25, 2022 at 2:52 pm

      I LOVE that you made it your own! If you follow the recipe exactly how I have it here, your added sugar is 9 grams per serving. The way you’ve done it with just 2 tablespoons of brown sugar, brings the added sugar down to just 3 grams. Next time I make it, I’m going to use Swerve brown sugar substitute. I think it will come out well.

  5. Mary Angelini on December 26, 2022 at 12:41 pm

    can you use quick oats in place of rolled oats?

    • Jill Weisenberger on December 27, 2022 at 5:02 pm

      Thanks for asking Mary. I haven’t tried it, but I understand it comes out well with a slightly different texture. If you try it, please let me know how it comes out.

  6. Bev Darnell on February 19, 2024 at 10:15 pm

    Hi! Piggy back on the last question with substituting rolled oats, I have steel cut oats in pantry. Can I substitute steel cut oats and if yes, would I use a lesser amount?

    • Jill Weisenberger on February 20, 2024 at 2:34 pm

      I haven’t tried it with steel cut oats. If you decide to experiment with that, I suspect you’ll need a similar amount, but a longer cooking time. Let us know what happens if you try it.
