Why You'll Love These Blueberry Baked Oats
Great to make ahead - This baked oatmeal lasts in the fridge for 3-4 days so you can make it ahead and just reheat a serving in the oven every morning. If you only want to cook a smaller batch, I recommend this Single Serving Baked Oatmeal.
Sweet and flavorful - Blueberries give this oatmeal flavor, sweetness, and a beautiful purple color. The flavors are really simple but so delicious. The oatmeal pairs well with yogurt, nut butter, berries, or even ice cream if served as a dessert!
Versatile - If you don't have blueberries, you can use other berries or a mix. Check out this Mixed Berry Baked Oatmeal, it's my all-time favorite sweet make-ahead breakfast. If you're all out of berries, this Peach Baked Oatmeal is also amazing! You can follow this recipe and change up the fruit and spices to whatever you have or are craving.
Ingredients
- Rolled oats - Use certified gluten-free oats if needed. Regular old-fashioned oats are the best for this recipe. Quick-cooking oats will yield a much denser texture and steel-cut oats wouldn't cook properly.
- Eggs - Eggs help bind everything together and make the texture more cake-like. I haven't tried any vegan replacements so I can't guarantee results.
- Almond milk - To keep the recipe dairy-free, I opted for almond milk but you can use any regular or non-dairy milk you prefer. I don't recommend using canned coconut milk because it's too thick. You can use boxed coconut milk instead.
- Blueberries - I used frozen wild blueberries but regular blueberries work just as well. You can use fresh or frozen berries.
- Raspberries - This is optional but they add a nice tang and balance out the sweetness of the maple syrup and blueberries.
- Flavorings - Vanilla extract, cinnamon, and cardamom give this oatmeal all the flavor it needs.
Variations and Substitutions
- More berries - I like adding raspberries to the oatmeal but this is optional. You can also try my Mixed Berry Baked Oatmeal which also has strawberries!
- More spices - The oatmeal has cinnamon and cardamom but you could add other spices like ground ginger, nutmeg, or allspice as well to add more flavor.
Step-by-Step Instructions
- Start by preheating your oven to 375F and prepare a 12x8-inch baking dish.
- In a medium bowl, mix together the oats, cinnamon, cardamom, and baking powder. Set that aside while you prep the rest of the batter.
- In a large mixing bowl, whisk together eggs, almond butter, maple syrup, and vanilla extract until smooth.
- Add almond milk and whisk again briefly to mix.
- Add the dry ingredients you mixed earlier into the wet ingredients and stir everything together until well mixed. I like to switch to a spoon here because it's easier than a whisk.
- Add blueberries and raspberries and stir again to incorporate.

- Pour the mixture into your prepared baking dish and top with more berries if desired.
- Sprinkle with turbinado sugar for extra sweetness and to help the oatmeal get a nice golden crust on top.
- Bake the oatmeal in the oven for 45-50 minutes. Slice into 6 squares and enjoy!
Tips & Tricks!
- Turbinado sugar - If you want the top of the oatmeal to be crunchy and caramelized, sprinkle the oatmeal with some turbinado sugar before you put it into the oven. It caramelizes but it doesn't melt completely which adds a nice crunch.
- Grease your baking dish - While this is optional, I recommend greasing your baking dish with butter. You could use cooking spray
Serving Suggestions
You can serve the baked oats on their own or add your favorite toppings! Below are some of my favorites to give you inspiration.
- Fresh or cooked fruit - I like adding fresh strawberries, blueberries, blackberries, bananas, stone fruit, or simmered frozen berries. You could also serve it with some caramelized bananas or these Caramelized Peaches!
- Yogurt - Add a dollop of Greek yogurt or your favorite regular or dairy-free yogurt.
- Nut butter or seed butter - Drizzle the oatmeal with almond butter or add a spoonful of peanut butter. It would also be delicious with this Homemade Nutella!
- Serve it as a dessert - Cut the oatmeal into smaller squares and serve it with a dollop of vanilla ice cream and some whipped cream for dessert! You can even drizzle it with Homemade Chocolate Sauce!
Storing and Reheating
Refrigerator: Store any leftovers in an airtight container in the fridge for up to 3-4 days. Make sure the oatmeal has cooled completely before closing the container with a lid. If you're stacking the slices, I recommend adding parchment paper between each slice so they don't stick together.
Freezer: Freeze individual portions in freezer bags or in a freezer-safe container with parchment paper in between layers to make sure they don't stick together. Freeze for 3-4 months.
Reheating: You can eat the leftovers either cold straight from the fridge or warm them up in the oven. Preheat your oven to 300F (150F), transfer the oats to an oven-safe dish, and warm up for about 10 minutes or until warmed through.
FAQs
Yes, just use flax egg instead of eggs, or skip them altogether and add more almond milk. I haven't tried these substitutions but the batter is very forgiving so it should work fine. Keep in mind the baked oatmeal won't have a cakey texture without the eggs.
Yes, oats are naturally gluten-free but always choose certified gluten-free oats to be sure they are handled in a gluten-free facility.
Yes, the texture won't be the exact same after defrosting but you can cut the oatmeal into servings and freeze them separately in freezer-safe containers. Reheat the oats in a preheated oven at 300F.

Notes
Storing: Store any leftovers in an airtight container in the fridge for up to 2-3 days. You can also freeze the oatmeal in a freezer-safe container for 3-4 months. I recommend placing parchment paper in between the slices to avoid them getting stuck together.
Reheating: Preheat your oven to 300F (150C) and reheat the baked oats on a baking sheet or in an oven-safe dish for approx. 10 minutes. If your oatmeal is frozen, I recommend defrosting it overnight first or keeping it in the oven for longer.
