Healthy Blueberry Baked Oatmeal {Gluten Free, No Refined Sugar}

Start your day off right with this easy, healthy Blueberry Baked Oatmeal recipe. This make-ahead breakfast casserole is perfect for a grab and go meal or a lovely addition to brunch.

I did not grow up as a breakfast food lover. In fact, I'm known to eat the previous night's dinner for breakfast.

But that all changed when I fell in love with baked oatmeal. Filling you up without the need for a mid-morning nap, this recipe has enough protein to keep you going until lunch time!

Why I love Blueberry Baked Oatmeal:

• Baked oatmeal recipe can be made ahead of time and reheated (or eaten chilled). You can wrap individual pieces and freeze for later, too!
• It’s portable (hello, busy farm families!)
• With no refined sugar, it’s not overly sweet and better for you.
• This recipe is awesome for a family or can feed a crowd (or extra hungry teenagers) when doubled

Ingredients in Blueberry Baked Oatmeal

old fashioned or rolled oats: wholesome oats are the main ingredient because it's baked oatmeal! Either of these oats work great. You won't want to use quick oats or steel cut oats for this recipe. Use certified gluten free oats to make this a gluten free recipe.

baking soda: acts as a leavening agent, making your baked oatmeal lighter and fluffier.

cinnamon & vanilla: delicious flavor additions!

sea salt: Just a pinch works great in this recipe

eggs: act as the binder, plus they add a little protein.

maple syrup: nature's sweetness! If you don't have maple syrup, honey or agave nectar work.

milk: I use whole milk but you can use whatever you kind you have in your fridge. 2%, almond....I would think skim milk works too but I haven't tried it myself.

blueberries: fresh, juicy berries if you have them. This recipe really brings out their inherent sweetness. If blueberries aren't in season, you can substitute frozen berries. Just don't thaw them, pop them in right from the freezer!

How to Make Blueberry Baked Oatmeal

In under ten minutes, you'll be on your way to a healthy breakfast you'll feel good about feeding yourself and your family!

1. Preheat your oven to 350°F. In a medium sized bowl, combine dry ingredients (oats, baking soda, cinnamon, and sea salt). Mix.
   
2. In another bowl, combine 2 eggs, lightly beaten, maple syrup, vanilla extract and milk. I used whole milk but you can use whatever you have on hand. Whisk together and add to your dry ingredients.
   
3. Add the wet ingredients to the dry ingredients and mix using a spoon or spatula. Fold the blueberries into the batter taking care to be gentle (don't go crazy here, now is not the time to get your aggression out!) If you overwork the blueberries, you'll end up with a less appetizing oatmeal bake.
   
4. Grease a 9x9 baking pan. Pour in the oatmeal mixture and spread evenly. Bake for 35-40 minutes until the center is set. Allow to cool for 15-20 minutes before slicing and serving.

While it's baking it makes the kitchen smell SO GOOD. It's a homey, delicious scent that is edible, unlike all the candles in my household.

When my blueberry oatmeal was done baking, I took the pan out of the oven and sniffed it. Twice.

That, my friends is the sign of a good breakfast.

Can I use frozen berries?

Yes, you can use frozen blueberries! Add them to the recipe right before baking. Keep them frozen so you don't have a grey-purple oatmeal.

Can this recipe be doubled?

Again, the answer is yes! Bake in a 9 x 9 dish or if doubling, a 9 x 13 pan. You could also make these this blueberry oatmeal as muffins!

Leftovers can be wrapped in plastic wrap and frozen for several months.

Can I use different oats?

I recommend old fashioned oats for their texture and density. You could use quick oats if needed. I do not recommend using steel cut oats as they're a different type of oat altogether.

How to Make this Ahead:

Do you have too much time on your hands? Yeah, me either. Here are a few ways you can get ahead by making this baked oatmeal as part of your meal prep!

• Bake this ahead of time and freeze slices, individually wrapped
• Bake ahead of time and refrigerate
• Assemble as instructed up until the blueberries are added and refrigerate overnight. Just before baking, add the blueberries and pour into your prepared pan.

To reheat, microwave slices on a plate for about 30 seconds. If frozen, I recommend thawing in the refrigerator overnight and then reheating.
