Ingredients You’ll Need
One of my favorite things about Lemon Blueberry Baked Oatmeal is how it uses everyday ingredients, each with a special job to play. The subtle sweetness, lush berries, and zingy lemon all come together for the kind of breakfast you wake up excited for.
- Old-fashioned rolled oats: These create that tender, chewy base and soak up all the lovely flavors.
- Baking powder: Just a bit helps the oatmeal puff up and bake to perfection.
- Salt: Essential for balancing flavors and enhancing all the sweet and bright notes.
- Ground cinnamon: Adds a gentle warmth that cozies up to the lemon and blueberry.
- Lemon zest: The star for tangy brightness—it lifts and freshens every bite.
- Milk (dairy or non-dairy): Helps to bind and moisten, so the oats bake up creamy and soft.
- Maple syrup or honey: Natural sweetness that pairs perfectly with lemon and berries.
- Large egg: Binds the ingredients together, ensuring each square holds up.
- Melted coconut oil or butter: For richness and subtle flavor—either option makes the bake tender.
- Vanilla extract: Adds depth and that classic “baked goods” aroma.
- Fresh or frozen blueberries: You can’t skip these juicy gems; they offer bursts of sweetness and color.
- Additional lemon zest (optional): If you love a pop of citrus, sprinkle some on top right before serving.
How to Make Lemon Blueberry Baked Oatmeal
Step 1: Prep Your Pan and Oven
Start by preheating your oven to 350°F (175°C). Lightly grease an 8×8-inch baking dish—this quick step ensures easy cleanup and perfectly baked edges. This is the perfect moment to gather your ingredients, too.
Step 2: Mix the Dry Ingredients
In a large bowl, combine the rolled oats, baking powder, salt, ground cinnamon, and lemon zest. Give these a good stir so that each bite is nicely seasoned and every oat gets a touch of citrusy zing.
Step 3: Whisk the Wet Ingredients
In a separate bowl, whisk together the milk, maple syrup (or honey), egg, melted coconut oil (or butter), and vanilla extract. This mixture brings sweetness, moisture, and richness—together, they make the oats bake up soft and flavorful.
Step 4: Combine and Add Blueberries
Pour the wet ingredients over the dry and stir gently until just combined. Fold in the blueberries carefully, trying not to burst them if you’re using fresh ones. The batter will look a bit liquidy, but trust the process—the oats will soak it up beautifully as they bake!
Step 5: Assemble and Bake
Pour the mixture into your prepared baking dish and gently spread it out evenly with a spatula. Pop it in the oven and bake for 35 to 40 minutes, until the top is golden and the center is just set. Your kitchen will smell so inviting, you’ll be tempted to dig in immediately.
Step 6: Cool and Serve
Let the Lemon Blueberry Baked Oatmeal cool for about 10 minutes so it’s easier to slice and serve. If you like, shower the top with extra lemon zest for a citrusy aroma right before you cut it into squares.

Lemon Blueberry Baked Oatmeal Garnishes
For a burst of color and freshness, I love showering the top with a little more lemon zest and a handful of extra blueberries. A drizzle of maple syrup or a spoonful of creamy yogurt adds a luscious finishing touch, making your breakfast feel special every time.
Side Dishes
This dish stands well on its own, but if you’re feeling fancy, try serving it with scrambled eggs, crispy turkey bacon, or a fruit salad. The balance of sweet and savory makes the whole meal sing, and your breakfast table will look vibrant and inviting.
Creative Ways to Present Lemon Blueberry Baked Oatmeal
Serve in large, generous squares for a rustic look, or cut into smaller pieces for brunch gatherings. You can even bake the mixture in muffin tins for perfectly portable portions—kids love this version! For a fancy brunch, layer slices in glasses with yogurt and berries for a parfait-style treat.
Make Ahead and Storage
Storing Leftovers
Lemon Blueberry Baked Oatmeal keeps beautifully in the fridge, making your mornings that much easier. Place cooled pieces in an airtight container and store for up to 5 days—the flavors only get better as they meld together.
Freezing
If you’d like to have breakfast ready for weeks to come, this recipe freezes like a dream! Just cut fully cooled oatmeal into squares, wrap them individually, and pop them in a freezer bag or container for up to 2 months. Thaw overnight in the fridge or quickly warm in the microwave.
Reheating
To bring your Lemon Blueberry Baked Oatmeal back to that just-baked glory, reheat individual squares in the microwave for about 30 seconds to 1 minute. For a slightly crispier top, warm them in a 350°F oven for 8-10 minutes. Add a splash of milk if you want it extra moist.
FAQs
Can I use quick oats or steel-cut oats instead?
For best results, stick with old-fashioned rolled oats. Quick oats will make the bake too soft and mushy, while steel-cut oats need more liquid and a much longer baking time.
Can I make Lemon Blueberry Baked Oatmeal vegan?
Absolutely! Use non-dairy milk, swap the egg for a flaxseed egg (1 tablespoon ground flax mixed with 3 tablespoons water), and choose melted coconut oil and maple syrup. The results are still delicious and perfectly moist.
Do I need to thaw frozen blueberries?
No need to thaw them first—just toss frozen blueberries right into the batter. They may give the oatmeal a pretty, marbled purple hue, but the flavor is just as sweet and bright.
Can I double the recipe?
Definitely! Just bake in a 9×13-inch dish and keep an eye on the baking time—it might need a few extra minutes in the oven. It’s a great idea for brunch parties or meal prep for a crowd.
What’s the best way to serve leftovers?
Warm individual slices in the microwave or oven and add a splash of milk or dollop of yogurt. Garnish with extra lemon zest or even a handful of toasted nuts for a new twist each day.
Final Thoughts
I just know that once you try Lemon Blueberry Baked Oatmeal, it’ll find a regular spot on your breakfast table. It’s everything you love about morning comforts with a fresh, fruity twist—so don’t wait to give it a try. Happy baking, friend!
