How to Make Homemade Blueberry Oat Casserole in an Oven
Aunt Lou here.
To all my new to cooking and baking folks, I know this Homemade Blueberry Oat Casserole may look very scary with the long list of ingredients. I need you to trust me, the person who was once terrified to try and make a box of Hamburger Helper, when I say that you can absolutely make this delicious casserole. My advice is to take a deep breath, read over the entire recipe once, gather your ingredients and read each step slowly and carefully. When you do this, it really helps to get a recipe right the first time. This is a great way to build your confidence with any recipe.
(If this sounds like something you would rather make in your crock pot, do not worry. We have you covered. You can find the original, crock pot version of this recipe here.)
