How to Make Mixed Berry Vanilla Baked Oatmeal

Step 1: Prep Your Dish

Preheat your oven to 350°F (175°C). Lightly grease your baking dish with butter, coconut oil, or nonstick spray.

Step 2: Mix Dry Ingredients

In a large bowl, combine the oats, baking powder, and salt. Pour half of the oat mixture into the prepared baking dish.

Step 3: Add Berries

Layer half of the berries over the oat mixture in the baking dish. Then pour in the remaining oat mixture on top.

Step 4: Whisk Wet Ingredients

In the same mixing bowl, whisk together the eggs, milk, maple syrup, vanilla extract, and melted butter or coconut oil.

Step 5: Pour and Layer Again

Carefully pour the liquid mixture over the oats in the dish. Then scatter the remaining berries over the top.

Step 6: Bake

Bake uncovered for 25–40 minutes, or until the top is golden, the oats are tender, and the liquid has set.

Step 7: Serve

Serve warm with a splash of almond milk, a drizzle of extra maple syrup, or even a dollop of Greek yogurt on top.

FAQ: Mixed Berry Vanilla Baked Oatmeal

Can I make this oatmeal ahead of time?

Absolutely! It’s ideal for meal prep. Bake it on Sunday and enjoy it all week.

Can I use steel-cut or instant oats?

Is this recipe gluten-free?

Yes, if you use certified gluten-free oats.

Can I make it vegan?

Yes! Swap the eggs for flax eggs (1 tbsp flaxseed + 3 tbsp water per egg), use coconut oil instead of butter, and a plant-based milk.

What if I only have frozen berries?

You’re good to go! Use them straight from the freezer—no need to thaw.
