How to Make Lemon Blueberry Baked Oatmeal Recipe
Step 1: Prepare Your Oven and Baking Dish
Start by preheating your oven to 350°F (175°C). Lightly grease an 8×8-inch baking dish so your oatmeal doesn’t stick and you get those lovely golden edges everyone loves. This set-up step is quick but crucial for a perfect bake.
Step 2: Combine the Dry Ingredients
Grab a large bowl and whisk together the rolled oats, chia seeds, baking powder, cinnamon, and salt. This simple dry mixture forms the sturdy foundation of your Lemon Blueberry Baked Oatmeal Recipe and ensures even flavor throughout.
Step 3: Mix in the Wet Ingredients
To the dry mix, add almond milk, maple syrup, unsweetened applesauce, vanilla extract, lemon zest, and fresh lemon juice. Stir everything together until just combined. This blend brings moisture and brightness, mingling the sweet, tangy, and creamy notes beautifully.
Step 4: Fold in the Blueberries
Carefully fold in your fresh or frozen blueberries, making sure not to overmix. This way, the berries stay intact, offering juicy pops in every bite. The blueberries also add wonderful color contrast against the lemony oats.
Step 5: Transfer and Bake
Pour your mixture into the prepared baking dish and spread it evenly. Pop it into the oven and bake for 35-40 minutes. You’ll know it’s done when the top turns golden and the oatmeal feels set. The aroma at this stage is simply irresistible!
Step 6: Let It Cool and Serve
Once baked, let it cool for a few minutes so it firms up slightly and is easier to cut. While still warm, it’s absolutely divine, and you’re just moments away from enjoying a nourishing breakfast that feels like a special treat.
How to Serve Lemon Blueberry Baked Oatmeal Recipe

Garnishes
Top your serving with a handful of fresh blueberries or a drizzle of maple syrup for an extra hit of sweetness. A sprinkle of lemon zest or a few slivers of toasted almonds can also add a delightful crunch and brighten the presentation.
Side Dishes
This baked oatmeal pairs wonderfully with a side of creamy coconut yogurt or a dollop of almond butter for added protein. Fresh fruit or a citrusy smoothie can round out the meal beautifully for a refreshing balance.
Creative Ways to Present
For a grab-and-go breakfast, cut the baked oatmeal into squares and wrap them individually. You could also serve it warm in bowls topped with a swirl of yogurt and a sprinkle of granola for texture. Layering chilled portions with Greek yogurt and granola parfait-style is another fun twist that’s perfect for brunch.
Make Ahead and Storage
Storing Leftovers
Leftover Lemon Blueberry Baked Oatmeal can be stored in an airtight container in the fridge for up to 4 days. It keeps its flavor and texture well, making it perfect for quick breakfasts during a busy week.
Freezing
If you want to prep ahead even further, portion the baked oatmeal into freezer-safe containers and freeze for up to 2 months. Thaw overnight in the fridge before reheating to enjoy a freshly baked taste any day you want.
Reheating
To reheat, warm individual portions in the microwave for about 60-90 seconds or until heated through. You can also reheat in a preheated oven at 300°F (150°C) for 10-15 minutes, which helps preserve the delicious texture and warmth throughout.
FAQs
Can I use rolled oats instead of quick oats?
Absolutely! Rolled oats are perfect for this Lemon Blueberry Baked Oatmeal Recipe because they hold their texture better during baking, resulting in that satisfying chewy bite.
What if I don’t have almond milk?
No worries! You can substitute any plant-based milk like oat, soy, or cashew milk, or even dairy milk if you prefer. Just use the same quantity to keep the moisture balance.
Can I use frozen blueberries?
Yes, frozen blueberries work great. Just fold them in frozen and expect a slightly more vibrant juice release during baking, which adds a lovely natural sweetness and color.
Is this recipe gluten-free?
It can be, as long as you use certified gluten-free oats. Regular oats are naturally gluten-free but can be cross-contaminated if not labeled gluten-free.
Can I add nuts or seeds to this recipe?
Definitely! Adding chopped walnuts, almonds, or pumpkin seeds can add incredible texture and nutrition. Just sprinkle them in before baking or use as a topping after baking for a crunch.
Final Thoughts
This Lemon Blueberry Baked Oatmeal Recipe is the kind of breakfast that makes you excited to start your day. With its lively citrus notes and juicy bursts of blueberry, coupled with a comforting oat base, it’s both nourishing and downright delicious.
