How to Make Lemon Blueberry Baked Oatmeal Recipe
Step 1: Prep Your Oven and Pan
Start by preheating your oven to 350°F (175°C). Lightly grease an 8×8-inch baking dish to ensure nothing sticks and the oatmeal comes out cleanly. This step sets the stage for a perfect bake every time.
Step 2: Combine Dry Ingredients
In a large bowl, toss together the rolled oats, chia seeds, baking powder, cinnamon, and salt. These dry ingredients form the sturdy base of your baked oatmeal, offering texture and a subtle hint of spice.
Step 3: Add Wet Ingredients
To the dry mix, pour in the almond milk, pure maple syrup, unsweetened applesauce, vanilla extract, lemon zest, and fresh lemon juice. Stir everything until the ingredients are fully blended into a luscious batter, packed with flavor and moisture.
Step 4: Fold in Blueberries
Gently fold your blueberries into the batter. Whether fresh or frozen, they add juicy pops of sweet and tart that make each spoonful a pleasure. Be careful not to crush them for that beautiful burst in texture.
Step 5: Bake to Perfection
Pour the mixture into your prepared baking dish and spread it out evenly with a spatula. Place it in the oven and bake for 35 to 40 minutes, or until the top turns a gorgeous golden color and the oatmeal sets firmly. The aroma filling your kitchen will be irresistible!
Step 6: Cool Slightly and Enjoy
Once baked, give the oatmeal a few minutes to cool slightly. This step helps it firm up just enough for perfect slices or scoops. Serve warm to enjoy all the cozy flavors at their best.
How to Serve Lemon Blueberry Baked Oatmeal Recipe

Garnishes
Add a final flourish with fresh blueberries, a drizzle of pure maple syrup, or a sprinkle of lemon zest to enhance the already vibrant flavors and make your presentation shine. A dollop of Greek yogurt or a handful of toasted nuts can also add richness and texture.
Side Dishes
Pair this baked oatmeal with a side of fresh fruit salad or a warm cup of herbal tea or coffee to create a balanced and satisfying breakfast experience. It’s both hearty and fresh enough to complement lighter side dishes.
Creative Ways to Present
Serve the baked oatmeal in individual ramekins or bowls topped with granola for some crunch. You could also layer it in a parfait with yogurt and extra berries to make a stunning breakfast treat that looks as good as it tastes.
Make Ahead and Storage
Storing Leftovers
Leftover Lemon Blueberry Baked Oatmeal Recipe can be stored in an airtight container in the refrigerator for up to 4 days. Keeping it chilled helps maintain its texture and freshness, making it easy to reheat for busy mornings.
Freezing
This oatmeal also freezes beautifully. Slice it into portions and wrap each piece tightly in plastic wrap or foil before placing in a freezer bag. It will keep for up to 3 months, allowing you to enjoy homemade baked oatmeal anytime.
Reheating
To reheat, simply pop a portion in the microwave for 30 to 60 seconds or warm it in the oven at 350°F until heated through. You can add a splash of milk before reheating to restore its creamy texture and top with fresh fruit or syrup as desired.
FAQs
Can I use fresh and frozen blueberries interchangeably?
Absolutely! Both fresh and frozen blueberries work well in this Lemon Blueberry Baked Oatmeal Recipe. Just be gentle when folding in frozen blueberries to avoid turning the batter blue.
Is this recipe suitable for vegans?
Yes, this recipe uses plant-based almond milk and applesauce, making it fully vegan-friendly. You can enjoy all the flavors without compromising your dietary preferences.
Can I substitute chia seeds with flaxseeds?
Yes, ground flaxseeds can replace chia seeds if you prefer. Both add fiber and nutrition, though flaxseeds won’t provide the same gel-like texture chia does, but your baked oatmeal will still turn out delicious.
How can I make this recipe gluten-free?
Make sure to use certified gluten-free oats, as regular oats can sometimes be cross-contaminated. All the other ingredients in this Lemon Blueberry Baked Oatmeal Recipe are naturally gluten-free.
Can I add other fruits or nuts to this recipe?
Definitely! This recipe is very versatile. Try adding chopped nuts like walnuts or pecans, or mix in other fruits such as raspberries or diced apples for a fun twist.
