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.

If you're looking for more make-ahead breakfast ideas, try my chocolate baked oats, healthy make-ahead breakfast burritos, berry chia pudding or banana chocolate chip muffins.

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.

Doctor's Tip: Discover the remarkable health benefits of overnight oats! From promoting heart health to aiding in weight management, oats are packed with nutrition to kickstart your day!

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!

Chef's Tips

This baked oatmeal can easily be adapted to suit all types of diets!

To keep the dish vegan, you can use plant-based milk and yogurt, a flax egg, and coconut oil.
If you're watching your sugar intake, you can leave out the maple syrup or use any sweetener of your choice.
If you're following a gluten-free diet, use certified gluten-free oats.

Baked Oatmeal Has Endless Variations

Once you get the basic recipe for baked oatmeal down, you can make endless variations using your favorite ingredients.

In the summer, you can make baked oatmeal with sweet summer berries or luscious stone fruit like plums, nectarines, apricots or cherries. In the fall, you can make a batch with apples and cranberries.

My Peach Baked Oatmeal pictured here is a reader favorite that you must try! Warm, cinnamon-infused oatmeal is studded with sweet peaches and topped with thick, creamy vanilla yogurt. Yum! It's super easy to make and your whole family will love it!

How To Serve This Dish

I love to eat baked oatmeal warm with a some milk drizzled on top and 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!).

The Greek yogurt adds a nice boost of protein to keep you full and satisfied all morning long.

A hearty and satisfying breakfast that’s bursting with flavor, whole grains, protein, fiber, and antioxidants. What more can you ask for?

Recipe FAQs

Can you make baked oatmeal ahead of time?

Yes, this baked oatmeal is the perfect make-ahead dish! You can assemble the whole dish the night before and refrigerate it. The next day, just pop it in the oven and bake as directed.

Can you freeze baked oatmeal?

Yes, you can freeze baked oatmeal. You can wrap the dish with plastic wrap and freeze the whole thing or cut it into pieces and freeze the individual portions. The whole dish can be reheated in the oven. The individual portions can be reheated in the oven or microwave.

Can you use quick oats instead of old-fashioned oats in this recipe?

Yes, you can use quick oats in this recipe as some of my readers have noted. Quick oats are just rolled oats that go through further processing to decrease cooking time. They're partially cooked and then rolled out thinner than old-fashioned oats. Using quick oats may give the baked oatmeal a slightly finer, more cake-like consistency, which is delicious!
