How to Make Zucchini Blueberry Baked Oatmeal Recipe
Step 1: Preheat and Prepare
Wash your hands because it’s time to get cozy in the kitchen! Preheat your oven to 350°F (175°C) and grease your baking dish well. This little step ensures the baked oatmeal won’t stick and forms a golden, crisp edge that contrasts the tender inside.
Step 2: Mix the Dry and Wet Ingredients
In a large bowl, whisk together the rolled oats, milk, maple syrup, vanilla extract, cinnamon, baking powder, and salt until everything is evenly combined. This mix promises each bite is bursting with flavor and the right amount of lift for that perfect baked texture.
Step 3: Fold in the Good Stuff
Gently stir in the grated zucchini, fresh blueberries, and if you’re using them, those crunchy chopped walnuts. Folding instead of stirring vigorously keeps the blueberries whole and helps the zucchini stay tender, making sure flavors stay vibrant and textures balanced.
Step 4: Bake to Golden Perfection
Pour this luscious mixture into your prepared baking dish, spreading it out evenly so it cooks uniformly. Pop it in the oven and bake for 30 to 35 minutes, or until the top becomes beautifully golden and firm to the touch—the smell alone will have you eagerly anticipating your first bite.
Step 5: Cool and Serve
Allow the baked oatmeal to cool slightly—it’s worth the wait! This resting time lets everything set so when you serve it, each square holds together perfectly without crumbling.
How to Serve Zucchini Blueberry Baked Oatmeal Recipe

Garnishes
Adding a touch of extra sweetness or creaminess elevates this dish effortlessly. A drizzle of maple syrup brightens the flavors, or a generous dollop of rich Greek yogurt adds a tangy contrast that pairs beautifully with the blueberries and cinnamon.
Side Dishes
Want to turn this into a hearty brunch? Fresh fruit salad or a lightly toasted slice of sourdough bread makes a lovely companion. For a more indulgent feel, crispy bacon or a side of scrambled eggs work perfectly to lend some savory balance.
Creative Ways to Present
Think beyond the baking dish! Try portioning the baked oatmeal into individual ramekins for a charming presentation, or layer it in a glass parfait with yogurt and extra berries for an impressive, yet simple, brunch centerpiece. The speckled colors of the zucchini and blueberries make it visually inviting no matter how you serve it.
Make Ahead and Storage
Storing Leftovers
Leave your baked oatmeal to cool completely, then transfer any leftovers to an airtight container. Stored in the fridge, it will keep perfectly for up to 4 days, making it a fantastic grab-and-go breakfast for busy mornings.
Freezing
This dish freezes beautifully, so don’t hesitate to make a double batch. Slice it into portions, wrap each tightly in plastic wrap, then place into a freezer-safe bag or container. Frozen portions will last up to 3 months, letting you enjoy your favorite Zucchini Blueberry Baked Oatmeal Recipe anytime you want.
Reheating
To safely bring your baked oatmeal back to life, reheat individual portions in the microwave for about 1 to 2 minutes until warmed through, or bake in the oven at 350°F (175°C) for 10 to 15 minutes. Either way, you’ll enjoy that freshly baked taste without the wait.
FAQs
Can I use frozen blueberries instead of fresh?
Absolutely! Frozen blueberries work well if you don’t have fresh ones on hand. Just toss them in frozen and gently fold into the batter—the baking time remains the same, but expect a bit more juice in the final dish.
Do I need to peel the zucchini?
Nope! The skin is thin and adds good color and nutrients. Make sure to grate it finely and squeeze out excess water to avoid sogginess in your baked oatmeal.
Is this recipe suitable for a gluten-free diet?
It can be! Just be sure to use certified gluten-free rolled oats. This small swap keeps your Zucchini Blueberry Baked Oatmeal Recipe safe and delicious for those avoiding gluten.
Can I substitute the walnuts?
Of course. If you want a nut-free version or prefer different textures, try chopped pecans or almonds, or simply leave nuts out altogether. The oats and blueberries will still shine wonderfully.
How sweet is the oatmeal?
This recipe is mildly sweet from the maple syrup and blueberries, making it perfectly balanced. You can always add more syrup on top if you like it sweeter or keep it lighter for a more natural flavor.

Once you make this Zucchini Blueberry Baked Oatmeal Recipe, it’s bound to become a cherished part of your breakfast rotation.
