Before moving to Pennsylvania, I had never heard of baked oatmeal but I was thrilled to have my first taste while on vacation with my in-laws. She made it before the trip and it was easy to warm up that morning. We like to have it warm with milk poured over the top. Since that first taste, this recipe has been on our regular rotation for hot breakfasts.

We serve it when guests come over and it’s perfect for the busy holiday season. Blueberry Baked Oatmeal is the perfect addition for any brunch you might be planning as well.

Making baked oatmeal regularly has really helped us to cut way back on the cereal consumption in our house. I knew that I didn’t always have time to make eggs for the kids every morning and I wanted something as easy as cereal for busy school mornings.

I can pull together this recipe in just 5 minutes on a Sunday afternoon and our family will enjoy it all week long.

Ingredients and Options for Blueberry Baked Oatmeal

Rolled Oats – You can use quick oats or rolled oats. We love to use rolled oats for the texture and because it is less processed. You can also do a half quick and half rolled oats.
Oil – The original recipe calls for vegetable oil but you can easily substitue coconut oil. I’ve done this several times and it works great.
Sugar – Regular white sugar works well, but to add a richer flavor you can use brown sugar instead. I also like to sprinkle a little turbinado sugar on top for a sweet crispy top.
Eggs – We use large or extra large eggs usually.
Milk – For a dairy free option you can very easily substitute almond or oat milk.
Berries – While this recipe calls for fresh or frozen blueberries. See my list of substitutes below for some other options.

Use good oats! We love to use mostly rolled oats because they hold up really well in this recipe and are more nutritious.
This is a great make-ahead recipe. I’ve found that this recipe just gets better over time. I like to make it the night before so it can sit overnight.
Try making blueberry baked oatmeal in muffin tins instead. This way you have small single servings that are perfect for busy mornings.
Try pouring warm milk or milk substitute over your baked oatmeal (it’s so good!)
