Ingredients You’ll Need
Simple ingredients come together beautifully to create this Lemon Blueberry Baked Oatmeal Recipe. Each element adds something special—from the hearty oats for texture to the fresh lemon for brightness, making the final dish light yet satisfying.
- 2 cups old-fashioned rolled oats: These provide a chewy, hearty base essential for that classic baked oatmeal texture.
- 1 tablespoon chia seeds: A little powerhouse adding fiber, omega-3s, and helping bind the oats together.
- 1 teaspoon baking powder: Gives a subtle lift to make the oatmeal fluffy, not dense.
- 1/2 teaspoon ground cinnamon: Adds a warm, cozy spice that complements the lemon and blueberry perfectly.
- 1/4 teaspoon salt: Balances flavors and enhances the sweetness and tartness in the dish.
- 1 cup unsweetened almond milk (or any plant-based milk): Keeps the oatmeal creamy and light without overpowering the fresh flavors.
- 1/4 cup pure maple syrup: Natural sweetness that infuses every bite with a gentle caramel note.
- 1/4 cup unsweetened applesauce: Acts as a moistener and subtly sweet binder, plus it keeps things light.
- 1 teaspoon vanilla extract: Adds nuanced depth and rounds out the citrus and berry flavors.
- Zest of 1 lemon: Provides a fragrant, citrusy kick that awakens your senses.
- Juice of 1 lemon: Delivers bright acidity that perfectly balances the sweetness.
- 1 cup fresh or frozen blueberries: Bursting with antioxidants and juicy pops of flavor that make each bite exciting.
How to Make Lemon Blueberry Baked Oatmeal Recipe
Step 1: Prepare Your Baking Dish and Oven
Start by preheating your oven to 350°F (175°C). Lightly grease an 8×8-inch baking dish with a little oil or non-stick spray so your oatmeal bakes up perfectly without sticking.
Step 2: Combine the Dry Ingredients
Grab a large bowl and mix together the rolled oats, chia seeds, baking powder, ground cinnamon, and salt. This simple blend forms the foundation of flavor and texture. Mixing them well here ensures each spoonful has a balanced taste.
Step 3: Add the Wet Ingredients
Now pour in the almond milk, maple syrup, unsweetened applesauce, vanilla extract, lemon zest, and fresh lemon juice into the dry mix. Stir everything until smooth and well incorporated—this is where that bright lemon magic starts to shine.
Step 4: Fold in the Blueberries
Gently fold in the blueberries so you don’t crush them, keeping those juicy bursts intact. Whether fresh or frozen, they’ll add beautiful color and a sweet-tart counterpoint to the lemon-infused oats.
Step 5: Pour and Bake
Pour the oatmeal mixture into your prepared baking dish, spreading it out evenly with a spatula. Slide it into the preheated oven and bake for 35 to 40 minutes. You’ll know it’s done when the top turns golden and the oatmeal feels set to the touch.
Step 6: Cool Slightly and Serve
Remove from the oven and let it cool for a few minutes. This resting time helps the baked oatmeal to firm up a bit, making it easier to slice and giving you the perfect texture. Optional toppings like extra blueberries or a drizzle of maple syrup take it over the top!
How to Serve Lemon Blueberry Baked Oatmeal Recipe

Garnishes
A sprinkle of additional lemon zest or a handful of fresh blueberries brings brightness and freshness that makes every bite feel special. You could also add a dollop of Greek yogurt or a swirl of almond butter for extra creaminess and protein.
Side Dishes
Lemon Blueberry Baked Oatmeal pairs fabulously with a side of fresh fruit salad or a warm cup of herbal tea. For a heartier breakfast, serve alongside scrambled eggs or a light green salad to balance the sweetness.
Creative Ways to Present
Try slicing the baked oatmeal into bars for an on-the-go breakfast treat or cut into squares and layer with yogurt and granola for a stylish parfait. You can even transfer portions into mason jars for a charming, portable delight.
Make Ahead and Storage
Storing Leftovers
This Lemon Blueberry Baked Oatmeal Recipe keeps beautifully in an airtight container in the refrigerator for up to 4 days. Simply cover and pop it in so you have a quick, wholesome breakfast ready whenever you want.
Freezing
If you want to stockpile breakfasts, freeze the oatmeal in individual portions wrapped tightly in plastic wrap or in freezer-safe containers. It will keep well for up to 3 months and thaw quickly when you’re ready to enjoy.
Reheating
Warm leftovers gently in the microwave or oven. Adding a splash of almond milk before reheating helps keep the texture soft and moist. It tastes nearly as amazing the second time around, making it perfect for busy mornings.
FAQs
Can I use frozen blueberries in this Lemon Blueberry Baked Oatmeal Recipe?
Absolutely! Frozen blueberries work just as well as fresh ones. Just fold them in gently without thawing to prevent adding too much moisture to the batter.
