Notes
*Note: Nutrition facts are calculated assuming this recipe makes 8 servings, although I have found it makes more than that! To Prepare in Advance
Bake the night before & reheat. I usually make this Blueberry Baked Oatmeal the night before, store it in the fridge, then just warm in the oven the next morning. It takes 5 minutes to throw together and 35 minutes to bake, plus it uses ingredients I almost always have on hand!
Make batter ahead of time and bake in the morning. You can also make the batter the night before - just leave out the blueberries- and store it in an airtight container in the refrigerator. In the morning, fold in the blueberries, spread it into a baking dish and bake!
