Ingredients

This healthy baked oatmeal recipe uses just 10 simple ingredients that you likely already have on hand in your fridge or pantry:

Fresh or frozen blackberries both work, but definitely opt for fresh if given the choice, especially during blackberry season to enjoy its juiciness. Frozen berries will also bleed a bit more, but that really only affects the presentation.
Quick-cooking oats make for a slightly creamier oatmeal bake, which I prefer. I discuss the types of oats in more depth later in this post, but rolled oats are also fine to use in this recipe. Regardless of the type, I always make sure they are certified gluten-free.

How to Make It

1. Add the dry ingredients to a mixing bowl and stir to combine.

4. Transfer the mixture to a parchment-lined baking pan and use the bottom of a small glass and parchment paper to pack it down tight. I like to top it with extra berries here so they'll show when it comes out of the oven.

Recipe Tips

Swap in other fresh berries. This oatmeal bake recipe works with other juicy berries. Swap the blackberries out for strawberries, raspberries or blueberries, or mix a few together for a beautiful medley!
Make it your own! In addition to swapping the fruit, feel free to add other spices or wholesome ingredients such as walnuts, chia seeds, hemp seeds or pumpkin seeds. Top with plant-based yogurt or any nut butter for breakfast or vegan vanilla ice cream for dessert!

Choosing Which Oats to Use

Baking with quick-cooking oats, rolled oats, steel-cut oats... what's the difference and why does it matter?

Quick-cooking oats hold together better when baked, making them softer and not as chewy.
Rolled oats, also called old-fashioned oats, are slightly chewier than quick-cooking oats when cooked. They work perfectly fine in this recipe but I prefer the texture of quick-cooking oats more here.
Steel-cut oats do not work in this recipe because they take significantly longer to cook and require a lot more water. Plus, they are not gluten-free.
