This blueberry baked oatmeal is easily prepped in one bowl in less than 10 minutes. It makes a great breakfast or snack and is super customizable!
I love a big bowl of oatmeal for breakfast in the morning. I usually either cook it on the stove or make overnight oats the night before if I have a busy day ahead. This blueberry oatmeal bake is another easy alternative to classic oatmeal. It’s quick to make and tastes delicious!
I got this blueberry baked oatmeal recipe when I visited the Amish country while living in Ohio and have adapted it over the years to my families preference. It’s so easy to make and is prepped in just one bowl in less than 10 minutes. It’s great for shelf cooking and takes less than 10 ingredients – most of which you probably already have in your pantry.
My family loves this oatmeal for breakfast or snack time! The great thing about it is that it’s super customizable, so feel free to swap out the blueberries for another type of fruit or include other yummy mix-in’s like nuts or chocolate chips. Sometimes I’ll even make it without fruit, so everyone can add their own toppings. You really can’t mess it up!
How to make baked oatmeal

BAKE. Bake at 350°F for about 25 minutes, or until the middle is set and the edges are lightly golden. Let cool in pan for about 10 minutes prior to serving.
