Ingredients Breakdown

Every ingredient in this baked blueberry banana oatmeal plays a crucial role in creating the perfect texture and flavor:

Rolled oats – The star of the dish, providing a chewy, hearty base. Avoid quick oats for the best texture.

Ripe bananas – They add natural sweetness, moisture, and a creamy texture when mashed.
Fresh or frozen blueberries – Bursting with juicy flavor and antioxidants. Frozen berries work just as well if fresh aren’t in season.
Milk (dairy or plant-based) – Keeps the oatmeal moist and tender. Almond milk, oat milk, or whole milk all work beautifully.

Eggs – Help bind everything together for a sliceable texture.
Maple syrup or honey – A touch of natural sweetness to enhance the fruit flavors.
Cinnamon and vanilla extract – Warm spices that elevate the overall taste.

Baking powder – Gives the oatmeal a slight lift, making it fluffy rather than dense.

How to Make The BEST Baked Blueberry Banana Baked Oatmeal!

Follow these simple steps for a foolproof baked oatmeal every time:

Preheat your oven to 375°F (190°C) and lightly grease a 9×9-inch baking dish.

Mash the bananas in a large bowl until smooth. Add the eggs, milk, maple syrup, and vanilla, whisking until well combined.
Mix the dry ingredients – In a separate bowl, stir together the oats, cinnamon, baking powder, and a pinch of salt.
Combine wet and dry ingredients – Pour the wet mixture into the dry ingredients and stir until just combined. Gently fold in the blueberries.

Transfer to the baking dish – Spread the mixture evenly and top with a few extra banana slices and blueberries for a pretty finish.
Bake for 35-40 minutes – The oatmeal should be golden on top and set in the middle. Let it cool slightly before serving.

Pro tip: For extra caramelized flavor, drizzle a little extra maple syrup over the top before baking.

Pro Tips for the Best Results

Take your baked oatmeal to the next level with these expert tricks:

Use extra-ripe bananas – The spottier, the better! They’ll be sweeter and mash more easily.
Let the batter rest for 10 minutes before baking to allow the oats to absorb some of the liquid for a creamier texture.

For a crispier top, broil for the last 1-2 minutes of baking (watch closely to prevent burning).
If using frozen blueberries, toss them in a bit of flour before folding them in to prevent sinking.

Variations and Substitutions

This recipe is incredibly adaptable. Here are some delicious ways to switch it up:

Nutty crunch – Add chopped walnuts, pecans, or almonds for extra texture.
Chocolate twist – Stir in dark chocolate chips or cacao nibs for a decadent version.
Tropical vibes – Swap blueberries for diced mango or pineapple and add shredded coconut.

Gluten-free – Use certified gluten-free oats if needed.
Vegan option – Replace eggs with flax eggs and use plant-based milk.

What to Serve With It

While this baked oatmeal is delicious on its own, pairing it with the right sides can make it even more special:

A dollop of Greek yogurt or whipped cream for added creaminess.
Drizzle of extra maple syrup or a spoonful of almond butter.
Fresh fruit salad or a side of crispy bacon for a sweet-savory balance.

A hot cup of coffee or a refreshing glass of cold-pressed juice.

How to Store and Reheat

This baked oatmeal keeps wonderfully, making it ideal for meal prep:

Refrigerate – Store in an airtight container for up to 5 days.

Freeze – Slice into portions and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
Reheat – Warm individual servings in the microwave for 1-2 minutes or in the oven at 350°F (175°C) for 10-15 minutes.

Frequently Asked Questions (FAQs)

Can I use steel-cut oats instead of rolled oats?
No, steel-cut oats won’t soften enough in this recipe. Stick with old-fashioned rolled oats for the best texture.

Can I make this recipe without eggs?
Yes! Substitute each egg with a flax egg (1 tbsp ground flaxseed + 2.5 tbsp water) for a vegan-friendly version.

Why is my baked oatmeal too dry?
You may have overbaked it or used too many oats. Check for doneness at the 30-minute mark and adjust liquid slightly if needed.

Can I double this recipe?
Absolutely! Use a 9×13-inch baking dish and increase the baking time by 5-10 minutes if needed.
