What You Will Need
- rolled oats – the hearty base of the best baked oatmeal recipe, if you need it to be gluten-free make sure they are gluten-free certified rolled oats.
- coconut sugar – perfect for an added touch of sweetness!
- baking powder – a little bit to help with the structure for this baked good.
- kosher salt – just a pinch for added flavor and to help with the structure too!
- ground cinnamon & vanilla extract – both are perfect for adding flavor to all of your favorite baked goods.
- unsweetened almond milk – this will bring moisture to the dish. Substitute with regular milk if you aren’t concerned about it being dairy-free.
- eggs – holds it all together and gives structure to this delicious breakfast!
- butter – flavor plus it’s great for making the top crisp and brown.
- apple, blueberries, & peaches – a delicious combination of fresh and canned fruit that we love to use, but feel free to use any of your favorite fruit combinations!
How To Prep This Baked Oatmeal Ahead Of Time
If you want to prep this the night before, this is what you can do:
- Combine your dry ingredients and place in bowl and cover.
- Chop your apples and peaches and store in separate bowls.
- Set out your pan and another bowl for your wet ingredients ahead of time.
The next morning you can throw everything together quickly and pop it in the oven! I wish I could tell you that you could combine it all together the night before, but you would end up with a pan of overnight oats in the morning.
How To Make Healthy Baked Oatmeal
To start things off you can mix together the dry ingredients in a large bowl and the wet ingredients in a small bowl. Then pour the wet ingredients into the dry ingredients and mix to fully combine.
Now you can add the fresh blueberries, chopped apples, and chunks of peaches to the oat mixture.
Use a large wooden spoon to carefully fold in the fruit.
Then pour the mixture into a large prepared baking dish.
Place the baking pan on the middle rack of the oven and bake at 350 degrees F for 45-60 minutes.
Let it cool for a bit and enjoy!
How To Serve Healthy Baked Oatmeal
One of our favorite ways to serve this fresh baked oatmeal is to give it a fresh sprinkling of ground cinnamon and just a splash of almond milk. A drizzle of maple syrup or honey would also be amazing! On the side we love some added fresh fruit, Greek yogurt, a cup of cold brew coffee, a cup of hot tea, or a delicious mango smoothie! Or for a little added protein you could hard boil some eggs!
- Fruit variations: you can easily substitute other fruit for either the blueberry, apple or peaches! Feel free to use raspberries, blackberries or pears!
- Add-Ins: you can toss so many different things into this simple recipe, like nuts, chocolate chips, shredded coconut, flax, etc.
- Storage: any leftovers can be kept in an airtight container in the refrigerator for up to 5 days.
- Freezing: after it has cooled you can either cover the entire pan and store in the freezer for up to 3 months. Or you can cut into individual portions, wrap them in plastic wrap, and store in a freezer bag so that you can reheat them 1-2 at a time.
- Reheating: so simple! You can either place it back in the oven at 350 degrees F until heated through or place in the microwave for a quick breakfast.
