Ingredients You’ll Need
The beauty of this Zucchini Blueberry Baked Oatmeal is in its simplicity. Each ingredient brings something essential to the table, whether it’s flavor, texture, or a boost of nutrition. Here’s what you’ll need—and why they each matter:
- Old-fashioned rolled oats: The heart of the bake, giving it a chewy, hearty texture that holds up beautifully in the oven.
- Baking powder: This helps the oatmeal rise just enough, so you end up with a light, slightly fluffy bite instead of something dense.
- Cinnamon: Warm and comforting, cinnamon adds a cozy flavor that pairs perfectly with both zucchini and blueberry.
- Nutmeg: Just a hint brings subtle depth and a gentle, spicy aroma to every bite.
- Salt: Don’t skip this—salt enhances all the other flavors and keeps the oatmeal from tasting flat.
- Milk (dairy or non-dairy): Adds moisture and richness; use your favorite kind for a creamy base.
- Unsweetened applesauce: Naturally sweetens the bake and helps keep it moist without adding extra fat.
- Maple syrup or honey: Provides just the right amount of sweetness and brings a lovely depth of flavor.
- Egg: Binds everything together for a cohesive, sliceable bake.
- Vanilla extract: A splash of vanilla makes the whole dish taste bakery-fresh.
- Grated zucchini (squeezed): Adds moisture, nutrition, and a subtle green fleck—no one will guess there’s a veggie hiding in their breakfast!
- Fresh or frozen blueberries: Pops of juicy sweetness throughout; use frozen for convenience or fresh when they’re in season.
- Melted coconut oil or butter: Drizzling this on top gives the oatmeal a golden, tempting finish and a bit of richness.
How to Make Zucchini Blueberry Baked Oatmeal
Step 1: Prep Your Oven and Baking Dish
Start by preheating your oven to 375°F (190°C). Lightly grease an 8×8-inch baking dish with coconut oil, butter, or a quick spray of nonstick cooking spray. This ensures your Zucchini Blueberry Baked Oatmeal comes out easily and the edges get just a little crisp.
Step 2: Mix the Dry Ingredients
In a large mixing bowl, combine the rolled oats, baking powder, cinnamon, nutmeg, and salt. Give them a quick toss to evenly distribute all the spices and leavening, so every bite is full of flavor.
Step 3: Whisk the Wet Ingredients
Grab a separate bowl and whisk together the milk, applesauce, maple syrup or honey, egg, and vanilla extract. This mixture is your flavor-packed liquid base, and whisking well ensures the egg is fully incorporated for a smooth, even bake.
Step 4: Combine and Add the Goodies
Pour the wet ingredients into the bowl of dry ingredients, then stir until everything is combined. Now gently fold in the grated, squeezed zucchini and the blueberries. Fold carefully to keep the blueberries as whole as possible—you want those pretty bursts of color and flavor scattered throughout.
Step 5: Assemble and Bake
Pour the entire mixture into your prepared baking dish, spreading it out evenly. Drizzle the melted coconut oil or butter over the top. This step gives the oatmeal its signature golden, tempting finish. Slide it into the oven and bake for 35 to 40 minutes, or until the top is golden and the center is just set. Let it cool for about 10 minutes to make slicing easier (and to avoid burning your tongue on those hot blueberries!).
How to Serve Zucchini Blueberry Baked Oatmeal

Garnishes
A little garnish can take your Zucchini Blueberry Baked Oatmeal from everyday to extraordinary. Try a dollop of Greek yogurt, a splash of milk, or a sprinkle of chopped nuts for crunch. For a touch of indulgence, a drizzle of extra maple syrup or a dusting of powdered sugar is always welcome.
Side Dishes
This oatmeal bake pairs beautifully with breakfast classics. Serve it alongside scrambled eggs, a crisp green salad, or fresh fruit for a balanced meal. If you’re hosting brunch, a platter of smoked salmon or a side of breakfast sausage makes it extra special.
Creative Ways to Present
Slice the Zucchini Blueberry Baked Oatmeal into squares and serve in individual bowls for grab-and-go breakfasts. For a fun twist, layer warm squares with yogurt and more berries in parfait glasses, or cut into small cubes and skewer with fresh fruit for a kid-friendly breakfast kabob.
Make Ahead and Storage
Storing Leftovers
Any leftover Zucchini Blueberry Baked Oatmeal can be cooled completely, then covered and stored in the refrigerator for up to five days. It holds up well and remains moist, making it a fantastic option for meal prepping your breakfasts ahead of time.
Freezing
This baked oatmeal freezes beautifully! Simply cut into individual portions, wrap each square tightly in plastic wrap or foil, and store in a freezer-safe bag or container. Thaw overnight in the fridge or pop a square straight into the microwave for a quick defrost.
Reheating
To reheat, microwave a square on medium for 30 to 60 seconds, or until warmed through. You can also reheat larger portions in the oven at 350°F (175°C) for about 10 minutes. Add a splash of milk before reheating to keep it extra moist and delicious.
FAQs
Can I use quick oats instead of old-fashioned rolled oats?
It’s best to stick with old-fashioned rolled oats for this recipe, as they provide the perfect texture. Quick oats may make the bake a bit mushy, while steel-cut oats won’t soften enough in the baking time.
Do I have to peel the zucchini first?
No need to peel the zucchini—the skin is thin and tender, and it adds a lovely fleck of green to your Zucchini Blueberry Baked Oatmeal. Just be sure to squeeze out as much moisture as you can after grating.
Can I make this recipe vegan?
Absolutely! Swap the egg for a flax egg (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water), use non-dairy milk, and choose maple syrup over honey. Coconut oil is perfect for keeping it dairy-free as well.
Will frozen blueberries work?
Yes, frozen blueberries are a great choice—no need to thaw them first. Just fold them in gently to avoid turning the batter purple, and bake as directed.
Can I double the recipe for a crowd?
Definitely! Just bake in a 9×13-inch dish and add a few extra minutes to the baking time. Keep an eye on the center to make sure it’s fully set before serving.
Final Thoughts
There’s something truly special about the way Zucchini Blueberry Baked Oatmeal brings together comfort, nutrition, and a burst of color all in one pan. Whether you’re meal prepping for the week or treating yourself to a cozy breakfast, this recipe is sure to brighten your mornings. Give it a try—you might just find a new staple for your breakfast table!
