Ingredient Notes to Make Baked Oatmeal with Blueberries
To make this recipe, there are just a few easy ingredients that are needed. They can all be found in the kitchen, at the store or can be substituted.
Get the full printable recipe with specific measurements and directions in the recipe card below.
- Oats: It’s best to use rolled oats. Quick oats will cook too quickly and end up soggy.
- Blueberries: I love to use fresh, in season berries for all of my recipes.
- Maple Syrup: I prefer to use real maple syrup as my sweetener for oatmeal.
- Milk: Feel free to use dairy milk or almond milk in this baked oatmeal recipe with blueberries.
Baked Oatmeal Variations and Substitutions
This recipe is super easy to customize. I like to take it to the next level by using different ingredients or trying different flavors.
- Sweeteners: Instead of syrup try honey, brown sugar or stevia for a sugar-free option.
- Milk: Any milk including whole milk, 2%, skim, buttermilk, soy, oat, coconut milk or cashew milk can be used.
- Spices: Add nutmeg, cardamom, ginger or even pumpkin pie spice with the cinnamon.
- Nuts: Chopped pecans, almonds or cashews can be added in addition to or instead of walnuts for extra crunch and healthy fats.
- Seeds: Try chia seeds, flax seeds or hemp seeds for added nutrition.
- Coconut: Stir in some sweetened or unsweetened shredded coconut.
- Chocolate Chips: Try white, dark or milk chocolate chips for a treat.
- Protein Powder: Mix in a scoop of unflavored or vanilla protein powder with the dry ingredients for an extra boost.
- Flavor Extracts: Vanilla extract is standard, but almond extract, lemon extract, or even a touch of orange zest can elevate the flavor.
How to Make Baked Blueberry Oatmeal
This recipe comes together in 4 easy to follow steps. This easy breakfast is so good, it’s in my weekly meal rotation.
Get the full printable recipe with specific measurements and directions in the recipe card below.
- Preheat Oven and Prep Pan: Preheat the oven and grease a baking dish.
- Mix the Ingredients: In a large mixing bowl, mix together the rolled oats, some of the chopped walnuts, baking powder, cinnamon and salt. In another bowl, mix the maple syrup, milk, eggs, butter and vanilla.
- Layer the Casserole: Spread half of the blueberries on the bottom of the dish. Evenly sprinkle the oat mixture over the top of the berries, then pour the liquids on top. Top with the rest of the nuts and blueberries.
- Bake the Oatmeal: Bake the dish until the top is brown and the oats have set. Let the oatmeal cool before serving.
Prep Ahead Suggestions to Make Blueberry Baked Oatmeal
Preparing baked oatmeal ahead of time can be the best way to go. Make banana blueberry oats in advance to be able to enjoy it whenever.
- Overnight Oats Style: Combine all dry ingredients in the baking dish. In a separate bowl, whisk together all wet ingredients. Cover both and refrigerate overnight. In the morning, pour the wet over the dry, stir, and bake.
- Full Assembly & Refrigerate: Assemble the entire easy baked oatmeal in the baking dish, cover tightly with plastic wrap or foil, and refrigerate for up to 1-2 days before baking. You might need to add 5-10 minutes to the baking time if baking from cold.
- Bake Ahead: Bake the entire batch, let it cool completely, then portion and store baked oats for quick reheating during the week.
Alternate Cooking Methods for Healthy Baked Oatmeal
Make this recipe another way by using your air fryer or crock pot. You can even make individual portions.
- Muffin Tin Baked Oatmeal: Divide the mixture into greased muffin tins for individual servings. Baking time will be significantly reduced (15-25 minutes).
- Individual Ramekins: Bake in oven-safe ramekins for single servings. Adjust baking time as needed.
- Slow Cooker (less common): Some recipes adapt baked oatmeal for a slow cooker, resulting in a softer texture. This usually involves lower liquid and longer cooking times on low.
- Air Fryer (for small portions/muffins): If using a small oven-safe dish or muffin tins that fit in your air fryer, you can bake individual portions. Reduce temperature and cooking time.
How to Store, Freeze, Reheat and Use Leftovers
- Store: Once cooled, store covered in an airtight container in the refrigerator for up to 5 days.
- Freezer: Baked oatmeal freezes exceptionally well!
- Whole Batch: Wrap the cooled baked oatmeal tightly in plastic wrap and then foil, or place in a freezer-safe container. Freeze for up to 3 months.
- Individual Portions: Once cooled, slice into portions, wrap each slice individually in plastic wrap, and then store in a freezer-safe bag or container. This makes for super convenient grab-and-go breakfasts.
- Reheat: Reheat individual portions in the microwave or oven until warmed through. If using the oven, cover with foil to prevent drying.
- Use Leftovers: Enjoy leftovers again as brunch, a snack, dessert or topping on Greek yogurt parfaits or fruit salads.
Common Questions About This Oat Recipe
What Kind of Oats Should I Use?
Use rolled oats—not quick or steel‑cut—for best texture
Why is my Baked Oatmeal Dry/Soggy?
If your oatmeal is too dry, you didn’t add enough liquid or you may have baked for too long. If it’s soggy, you probably added too much liquid or used the wrong kind of oats.
Is it Gluten-Free?
No, but it can be by using gluten-free rolled oats.
Expert Tips for Making This Recipe
- Don’t Overmix: Mix until just combined. Overmixing can develop the gluten in the oats and make the texture tougher.
- Let it Rest: While not strictly necessary, letting the assembled mixture sit for 10-15 minutes before baking allows the oats to absorb some liquid, leading to a more tender result.
- Even Distribution: Ensure blueberries (and any other add-ins) are evenly distributed so every bite gets some goodness.
- Grease Your Dish: Always thoroughly grease your baking dish to prevent sticking.
- Check for Doneness: Baked oatmeal is done when the liquid is mostly absorbed, the top is set, and the edges are lightly golden. A knife inserted into the center should come out mostly clean.
- Cool Slightly Before Slicing: While delicious warm, letting it cool for 5-10 minutes after baking helps it set and makes it easier to slice cleanly.
- Toppings: Enhance the experience with a drizzle of maple syrup, a dollop of yogurt, a splash of milk or cream, or a sprinkle of chopped nuts. Feel free to add other fruits like sliced banana or raspberries.
- Serve this Recipe With: Serve the best baked oatmeal with Ham and Egg Cups, Easy Blueberry Cobbler or Overnight Apple Pie Oats.

We recently tried baked oatmeal and have fallen in love with it. And as for blueberries…fuhgeddabowddit…we love them too! I will be pinning this recipe. Found you through Bloggy Moms.
Thanks for stopping by! We love ANYTHING with blueberries! 🙂
Forgot to add, next time I make this, will toast the nuts first. I like my nuts with a little crunch to them
Just made this today and really liked it. I used frozen wild blueberries, so the dish came out very purpley, but the taste is very comfy! I will be enjoying this all week, too, as an easy reheat breakfast. Thanks for sharing
This sounds great. I make something similar, but with a few more ingredients. One question: how many servings does this make? Many, many thanks! Kelly
You’re very welcome! I would say it makes about 6 one cup servings. Enjoy! 🙂
This sounds like a great breakfast idea. It is nice that you can bake it and reheat it for those busy mornings.
That’s exactly what I love about it! 🙂
