Zucchini and Oatmeal Bake
A cozy, lightly sweet baked oatmeal made with wholesome rolled oats, fresh zucchini, warm cinnamon, and vanilla. It has a soft, tender center with lightly golden edges and makes an excellent make-ahead breakfast or snack. Similar zucchini baked-oatmeal recipes use rolled oats, eggs, milk, shredded zucchini, cinnamon, and baking powder, with baking times generally around 30–40 minutes.
Ingredients
For the Bake
2 cups old-fashioned rolled oats
1½ cups finely grated zucchini
2 large eggs
1¼ cups milk
⅓ cup pure maple syrup or honey
2 tablespoons melted butter or coconut oil
2 teaspoons vanilla extract
1½ teaspoons ground cinnamon
½ teaspoon ground nutmeg
1 teaspoon baking powder
¼ teaspoon salt
½ cup chopped walnuts or pecans, optional
¼ cup raisins or dried cranberries, optional
Optional Toppings
Greek yogurt
Chopped walnuts
Fresh berries
Banana slices
A drizzle of maple syrup
Peanut or almond butter
Instructions
Preheat the oven to 350°F (175°C).
Lightly grease an 8×8-inch baking dish or line it with parchment paper.
Grate the zucchini using the smaller side of a box grater.
Place the grated zucchini in a clean kitchen towel or paper towels and gently squeeze out some of the excess liquid. Don’t dry it completely—the moisture helps keep the oatmeal tender.
In a large bowl, whisk together the eggs, milk, maple syrup, melted butter or coconut oil, and vanilla.
Add the rolled oats, cinnamon, nutmeg, baking powder, and salt. Stir until well combined.
Fold in the shredded zucchini.
If using, stir in the chopped walnuts and raisins.
Pour the mixture into the prepared baking dish and spread it evenly.
Let the mixture sit for 5 minutes so the oats can begin absorbing some of the liquid.
Bake for 35–40 minutes, or until the center is set and the top is lightly golden.
Remove from the oven and let it cool for 10–15 minutes before slicing.
Serve warm with Greek yogurt, berries, nuts, or a small drizzle of maple syrup.

Tips for the Best Zucchini Oatmeal Bake
Don’t completely squeeze the zucchini dry: A little moisture helps the baked oatmeal stay soft.
Use old-fashioned rolled oats: They provide better texture and structure than instant oats.
Don’t overbake: The center should be set but still tender. It will continue to firm up as it cools.
For extra crunch: Sprinkle chopped walnuts over the top before baking.
For meal prep: Cool completely, cut into squares, and refrigerate in an airtight container for up to 3–5 days, depending on the ingredients used. Similar zucchini baked-oatmeal recipes recommend refrigeration for several days.

Higher-Protein Version

Q&A
Q: Can I make this the night before?
Yes. You can mix the ingredients, cover the dish, refrigerate overnight, and bake the next morning. Overnight soaking can help the oats absorb the liquid and develop a softer texture.
Q: Why is my oatmeal bake watery?
The zucchini may contain too much water. Gently squeeze excess moisture from the grated zucchini before adding it.
Q: Can I use quick oats?
You can, but old-fashioned rolled oats generally provide a better chewy texture and structure.
Q: Can I leave out the eggs?
Yes. A flax or chia egg can be used as an egg-free alternative in similar baked-oatmeal recipes.
Q: Can I make it dairy-free?
Absolutely. Use unsweetened almond, oat, soy, or another plant-based milk and dairy-free butter or coconut oil.
Q: Can I reduce the sugar?
Yes. Reduce the maple syrup to ¼ cup for a less-sweet version, especially if you’re adding banana, raisins, or chocolate chips.
Q: Can I freeze it?
Yes. Cool completely, cut into individual portions, wrap well, and freeze. Thaw overnight in the refrigerator and reheat before serving.
Q: What should I serve with it?
Greek yogurt, fresh berries, banana, chopped nuts, nut butter, or a small drizzle of maple syrup are all excellent choices.
Q: Is zucchini noticeable?
Not much. Finely grated zucchini becomes tender during baking and blends into the oatmeal, while cinnamon and vanilla give it a zucchini-bread-style flavor.
