This tasty breakfast is made with simple, nutritious ingredients that can be found in any grocery store. Here's what you'll need:
- Blueberries + Bananas - Of course, you'll need some fresh blueberries and bananas. If you don't have both on hand, you can also make it with just one fruit.
- Oats - You'll use old fashioned rolled oats for this recipe. I don't recommend using instant oats or steel cut oats, because they absorb liquids differently and have different cooking times.
- Nuts - Chopped nuts add flavor and texture to the finished oats. I used walnuts, but pecans and other nuts are okay, too. Feel free to skip the nuts, if you prefer.
- Cinnamon - Fragrant ground cinnamon add that classic oatmeal flavor that you know and love.
- Brown Sugar - This recipe is lightly sweetened brown sugar.
- Vanilla - A little vanilla extract adds another layer of flavor this breakfast bake.
- Milk - For best results, use 2% or whole milk. Plant based milks are also fine (I like using soy milk).
- Eggs - The recipe uses two large eggs, which help bind the ingredients together.
- Leavener - Baking Powder helps the oats rise a bit, which lightens the overall texture.
- Salt - A little kosher salt perks up all the other flavors.
This recipe is naturally vegetarian, as well as gluten free. If you have a gluten allergy, use oats marked gluten free to avoid cross-contamination. You can also make the recipe vegan by swapping in plant based milk and skipping the eggs (or by using a vegan egg replacement).

Grab a small bowl to beat the egg, a large bowl to mix the oatmeal together, and an 8 x 8-inch square pan for baking. If you're looking for a baking dish that goes from the oven to the table, check out my fave Emile Henry Square Baker. It's easy to clean and looks so pretty when serving guests!
How to Make Blueberry Baked Oatmeal
Let's talk about how to make this recipe ... it's so simple! You'll find a detailed recipe card below, but here's an overview of the steps:
- Mix the oats. Start by combining the oats, cinnamon, brown sugar, baking powder, and salt. Then stir in the milk, eggs, and vanilla extract. Make sure to mix everything together really well.
- Cover bottom of pan with fruit. Place the blueberries in the bottom of your pan, then top with the bananas and nuts. Reserve about a quarter of each for topping the oatmeal.
- Top fruit with oats. Pour the oatmeal mixture over the fruit. Smooth the top, then sprinkle on the reserved fruit and nuts.
- Bake the oats. You'll know the oatmeal is done when it's set, and the top is lightly browned.
Don't you just want to dig into that scrumptious Blueberry Banana Baked Oatmeal right now?! And trust me, it tastes even better than it looks.
As the casserole cooks, the bottom gets a little custardy, but the oats on top stay chewy. The blueberries become super juicy, and the bananas add the ideal amount of sweetness. Pretty much the perfect combination of textures and flavors!
If you feel like experimenting, this recipe is easily customizable! Here are a few ideas to try:
- Fruit - The two fruits used here work great together, but you can make this recipe with just blueberries or just bananas, too. You could also swap one of the fruits out for strawberries, raspberries, blackberries, peaches, and more. Dried fruit, such as cranberries or raisins, will also work.
- Nuts - I used walnuts when developing this recipe, but other nuts (like pecans, pistachios, or almonds) will also work. You could also skip the nuts, if you prefer.
- Spices - I kept things simple and used cinnamon, but other warm spices, like cardamom, cloves, ginger, nutmeg, or allspice, would also be delish. A little fresh lemon zest would be tasty paired with the blueberries.
- Vegan - To make the recipe vegan, use plant based milk and skip the eggs (or use a vegan egg replacement).
- Cups - If you'd prefer to portion the recipe into single servings before baking, cook it in a muffin tin instead of a square pan. Spray the cups with nonstick spray before adding the fruit and oats, and watch closely, because the baking time will be about 10 to 15 minutes shorter.
As you can probably guess from the photos, these Blueberry Baked Oats have a different texture than you may be used to. Compared to the creamy porridge you get when cooking oats on the stove, this recipe is more of a breakfast casserole with a firmer, bread pudding-like consistency.
Enjoy the oats as-is, or serve them with yogurt and fresh fruit, like I did. You might even like them with milk. For a sweeter breakfast, sprinkle a little brown sugar or drizzle some maple syrup over the top.
This Blueberry Banana Baked Oatmeal is an excellent make ahead breakfast. It's also great for meal prep ... prepare the recipe on Sunday, then enjoy a quick, delicious meal all week! Refrigerate leftovers in an airtight container, and they'll stay fresh for three to four days. Then reheat gently in your microwave before eating.
Leftovers can also be frozen for up to two months. I recommend wrapping individual portions separately, and then storing them in a larger container. That way, you can grab only what you need.
