The Perfect Make-Ahead Breakfast
I’m always looking for healthy breakfast ideas that will give me energy to get through the day. I work long shifts in the ER so keeping my stamina up throughout the day is really important.
I like to pack my own meals on work days. That way I don’t have to rely on what the hospital cafeteria is serving up.
This baked oatmeal is the ideal breakfast for me because I can bake it on the weekend for my whole family. Then I can take the leftovers to work the rest of the week.
Packed with Superfoods
This recipe is packed with superfoods! Superfoods are foods that are rich in compounds that have the power to positively affect our health, ward off disease, and increase longevity.
- Oats are nutritious whole grains that are packed with fiber. Fiber helps keep things moving along smoothly in our intestinal tract. A diet high in fiber also helps reduce cholesterol, regulate blood sugar levels, regulate blood pressure, and lower your risk of heart disease.
- Blueberries are superfoods too. They provide vitamin C, fiber, and powerful disease-fighting antioxidants. I love using blueberries in popsicles, smoothies, and fruit crisps.
- Walnuts are also packed with a wide variety of important nutrients. Did you know that one ounce of walnuts has 2.5 grams of the omega-3 fatty acid alpha-linolenic acid (ALA), 4 grams of protein, and 2 grams of fiber? This combination helps keep you feeling full and satisfied.

How to Make Blueberry Apple & Walnut Baked Oatmeal
Baked oatmeal is so easy to make! Here are the steps. Scroll down to the recipe card below for full recipe amounts and instructions.
- Mix your dry ingredients together (rolled oats, baking powder, cinnamon and salt).
- Mix your wet ingredients together (milk, Greek yogurt, egg, maple syrup, coconut oil or butter, and vanilla extract). A lot of recipes just use milk but I like to add some Greek yogurt to my dish. This adds a nice boost of protein.
- Scatter some blueberries, chopped apple, and walnuts around the bottom of an 8x8-inch baking dish. Top them with the dry ingredients. Then pour in the wet ingredients.
- Press it all down so that the dry ingredients are submerged in the liquid. Finally, top the dish off with some more blueberries, apples, walnuts, and a dusting of cinnamon, and pop it in the oven.
In 40-45 minutes, you’ll have a delicious, hot, baked breakfast dish that’s bursting with flavor. And your kitchen will smell delicious!
This baked oatmeal can easily be adapted to suit all types of diets!

How To Serve This Dish
I love to eat baked oatmeal warm with a some milk drizzled on top or a dollop of Greek yogurt and maple syrup. But it’s also really satisfying eaten cold, straight out of the fridge the next day (or as a midnight snack if you can’t wait until morning!).
