From Start to Finish: Baked Oatmeal with Blueberries and Bananas

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your baked oatmeal cooks evenly and comes out perfectly golden.
Step 2: Combine the Dry Ingredients
In a mixing bowl, combine the oats, baking powder, cinnamon, and salt. Stir until well mixed to ensure even distribution of the leavening agent and spices.
Step 3: Mix the Wet Ingredients
In another bowl, whisk together the milk, egg, honey or maple syrup, and vanilla extract until fully combined.
Step 4: Incorporate Bananas and Blueberries
Add the sliced bananas and blueberries to the wet mixture, gently folding them in to avoid smashing the berries.
Step 5: Combine Wet and Dry Mixtures
Pour the wet ingredients into the bowl with the dry ingredients. Stir until just combined, being careful not to overmix.
Step 6: Add Nuts
Fold in the chopped walnuts or pecans for added crunch and flavor.
Step 7: Transfer to Baking Dish
Grease your 9×9-inch baking dish and pour the oatmeal mixture into it. Spread it out evenly with a spatula.
Step 8: Bake
Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.
Step 9: Cool and Serve
Once baked, remove from the oven and let it cool for a few minutes. Cut into squares and serve warm, perhaps with a drizzle of extra honey or a splash of milk on top.
Allergy-Friendly Swaps

- For a nut-free option, omit the walnuts or pecans, or substitute with sunflower seeds.
- If you’re avoiding gluten, ensure your oats are certified gluten-free.
- For a dairy-free option, use almond milk, coconut milk, or any other plant-based milk.
- To make it vegan, substitute the egg with a flaxseed meal or chia seed mixture (1 tablespoon of flaxseed meal or chia seeds mixed with 3 tablespoons of water, let sit for 5 minutes to thicken).
What I Learned Testing
The beauty of baked oatmeal lies in its versatility. During testing, I discovered that using different fruits can yield delightful variations. Apples, peaches, and even pumpkin puree can be substituted for bananas and blueberries depending on the season. Additionally, the texture is incredibly forgiving; if you prefer a creamier bite, simply add a bit more milk before baking. Most importantly, this dish is a great way to use up ripe fruit that might otherwise go to waste, making it a sustainable choice for breakfast.
How to Store & Reheat
To store your baked oatmeal, let it cool completely before transferring it to an airtight container. It will keep well in the refrigerator for up to five days. For reheating, simply microwave individual portions for about 30-60 seconds or until warmed through. You can also enjoy it cold, straight from the fridge, with a dollop of yogurt or a splash of milk.
Reader Questions
Can I use frozen blueberries in this recipe?
Absolutely! Frozen blueberries work wonderfully in this baked oatmeal. Just toss them in frozen; there’s no need to thaw them first. They may make the mixture slightly wetter, but the baking time remains the same.
How can I make this recipe more filling?
To make your baked oatmeal more filling, consider adding a scoop of protein powder or an additional egg to increase the protein content. You could also serve it with a side of Greek yogurt for extra protein and creaminess.
Is it possible to make this ahead of time?
Yes, you can prepare the mixture the night before and store it in the refrigerator. In the morning, just pour it into the baking dish and bake as directed. This makes for an easy grab-and-go breakfast!
Can I add other fruits or spices?
Definitely! Feel free to customize the recipe by adding fruits like apples, strawberries, or even peaches. You can also experiment with spices such as nutmeg or ginger for a different flavor profile.
