Ingredients You’ll Need
These ingredients are straightforward but play a crucial role in delivering the rich, comforting flavor and wonderful texture that make this Blueberry Baked Oatmeal Recipe so irresistible. Each element—from the bread to the spices—adds a special touch that transforms humble components into breakfast magic.
- 6 cups cubed bread (brioche, challah, or French bread): Using a soft, slightly sweet bread creates the best custardy texture.
- 2 cups fresh or frozen blueberries: Bursting with flavor and natural sweetness, they give every bite a juicy pop.
- 4 large eggs: The binding agent that holds everything together and adds richness.
- 1 ½ cups milk (or dairy-free alternative): Adds creaminess and helps soak the bread perfectly.
- ½ cup heavy cream (or coconut cream): Enhances the custard’s silky texture and depth.
- ½ cup maple syrup or honey: Natural sweeteners that blend beautifully without overpowering.
- 1 tsp vanilla extract: Adds warmth and aroma, lifting all the flavors.
- 1 tsp cinnamon: A hint of spice that complements blueberries perfectly.
- ¼ tsp salt: Balances the sweetness and enhances all flavors.
- ½ cup chopped nuts (optional): Adds a delightful crunch and nutty contrast.
- Powdered sugar, for serving (optional): A light dusting for a beautiful finish and extra sweetness.
How to Make Blueberry Baked Oatmeal Recipe
Step 1: Prepare Your Oven and Dish
First things first, preheat your oven to a cozy 350°F (175°C). While it’s warming up, grab a 9×13-inch baking dish and give it a light grease. This prevents sticking and helps your baked oatmeal come out perfectly every time.
Step 2: Layer the Bread and Blueberries
Spread those cubed pieces of bread evenly across the dish—no overcrowding here! Then, sprinkle the blueberries generously over the bread. If you’re using frozen berries, no need to thaw; they’ll thaw and slowly release lovely juices as they bake.
Step 3: Whisk Together the Custard Mixture
In a large bowl, whisk the eggs with milk, heavy cream, maple syrup, vanilla extract, cinnamon, and salt. This mixture is going to soak into the bread cubes, making every bite soft and rich. Make sure everything is well combined for an even custard.
Step 4: Combine and Let Soak
Pour the custard over the bread and blueberries, pressing down gently to submerge all the bread pieces. This soaking step is crucial to getting that soft, pudding-like inside. Let it sit for 10 minutes at room temperature. For a more intense flavor, cover and refrigerate overnight.
Step 5: Add Nuts and Bake
Sprinkle chopped nuts on top if you like a little crunch. Slide your dish into the oven and bake for 35-40 minutes. You’re aiming for a golden brown top and a custard that’s set but still slightly wobbly in the center.
Step 6: Cool and Serve
Let the baked oatmeal cool just a bit before dusting powdered sugar on top. This cooling time helps it set more firmly, making it easier to cut and serve without falling apart.
How to Serve Blueberry Baked Oatmeal Recipe

Garnishes
Brighten up your Blueberry Baked Oatmeal Recipe with a drizzle of extra maple syrup, a dollop of creamy yogurt, or a sprinkle of toasted nuts. Fresh mint leaves or a handful of additional fresh blueberries add pops of color and freshness that make every bite more exciting.
Side Dishes
Although this dish is a hearty meal on its own, pairing it with crispy bacon or turkey sausage can bring savory balance. Fresh fruit salad or a glass of cold-pressed juice complements the sweetness perfectly without overwhelming the palate.
Creative Ways to Present
For a brunch gathering, serve your Blueberry Baked Oatmeal Recipe in individual ramekins, garnished with edible flowers or a swirl of whipped cream. Layer it in clear glasses with yogurt and granola for a stylish parfait twist that looks as delightful as it tastes.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover your leftovers tightly with plastic wrap or transfer to an airtight container. It will keep well in the refrigerator for up to 4 days, making it a perfect grab-and-go breakfast option that tastes just as good warmed up.
Freezing
This Blueberry Baked Oatmeal Recipe also freezes beautifully. Cut into portions and store each piece wrapped in foil or parchment paper and then in a freezer bag. It can last up to 3 months, so you’ll always have a comforting breakfast ready when you need it.
Reheating
Reheat your portions in the microwave for 1-2 minutes or in a preheated oven at 350°F for about 10 minutes. Warming it slowly brings back that custardy softness and helps reactivate the wonderful aromas of vanilla and cinnamon.
FAQs
Can I use frozen blueberries in this recipe?
Absolutely! Frozen blueberries work just as well as fresh in this Blueberry Baked Oatmeal Recipe. There’s no need to thaw them beforehand, as they’ll thaw during baking and release their delicious juices.
Is it possible to make this recipe dairy-free?
Yes, simply swap the milk and heavy cream for your favorite dairy-free alternatives such as almond milk or coconut cream. The recipe will still be rich and flavorful with those adjustments.
Can I prepare the Blueberry Baked Oatmeal Recipe in advance?
Definitely! You can prepare the entire dish the night before, refrigerate it to let the flavors develop, and then bake it fresh in the morning. This makes busy mornings so much easier and tastier.
What type of bread is best for this recipe?
Brioche, challah, or French bread are excellent choices because they soak up the custard well and become beautifully tender. Avoid very dense or whole-grain breads that might result in a heavier texture.
Can I add other fruits or nuts?
Feel free to experiment! Blackberries, raspberries, or chopped apples all complement the baked oatmeal nicely. Nuts like pecans or walnuts add great texture, so customize it to your taste.
