I’ve been craving warm and cozy breakfasts for the past couple of weeks. It’s been grey and chilly in Boston and I wake up wanting a hearty breakfast that is going to give me all the fall warm and fuzzies. Ya feel me, fam? We’re talking warm fall flavors – cinnamon, nutmeg, and ginger.

Oatmeal is one of my go-to breakfasts in the fall and winter because it’s satiating and satisfyingly cozy. But I don’t always want to dirty a pot every morning and wait for the oats to cook. Enter baked oatmeal! I get the satisfaction of hot oatmeal every morning but only have to make one batch for the work week and dirty one pan!

Baked oatmeal is custard-like vs. porridge-like, which is another reason I love it. I dig the hearty texture that almost reminds me of a bread pudding. The other cool thing about baked oatmeal is you can change up the add-in ingredients based on what you have on hand. Since apples are in-season right now, I decided to make an apple version but you could swap in whatever fruit (or frozen fruit!) you have on hand.

The walnuts add a little healthy fat and plant-based protein boost, bumping up the satiety factor of this breakfast. An oatmeal breakfast that will ACTUALLY hold me over for a few hours?! Mind. Blown.

This breakfast only takes 5 minutes of hands-on prep time. And 50 minutes hands-off in the oven. Now if that’s not #BREAKFASTGOALS, I don’t know what is.

Stay cozy, fam!

    I followed the recipe exactly and it’s bubbling over in an 8×8 pan? What went wrong?

    • Hi Morgan – I’m so sorry that happened! Thank you for the feedback. I’m going to update the recipe to use a 10×7 baking dish.

  2. Micheline

    This looks so satisfying. But…. I am severely allergic to walnuts, pistachios, and macadamias. . Could another nut, like plain peanuts work, or should I leave them out altogether?

    • Hey Micheline, if it were me personally, I’d leave them out altogether. Are you allergic to all tree nuts? If not, pecans would be a delicious substitution.

    Absolutely LOVE this recipe, as Scots, porridge is a staple in our home, overnight,
    bircher… but this recipe is such a delight. Some we’ve adapted and added raisins too and some days we switch to pecans or almonds, its a fab recipe so versatile ( my son loves it with custard for dessert lol) ill make a huge batch and its great to grab on the go, as a nurse who works a lot of nights its so easy to grab before shift or have warm with some Greek yogurt when i get home, thanks so much x

    For those of us counting calories- is there a way to work out roughly how many calories per serving?

    Such a lovely recipe and so filling too!

    I just discovered baked oatmeal about a month ago and trying different on line recipes. Your version of maple, apple and walnut is delicious and healthy. I had to stop myself from eating more than a quarter of the pan. As a retired dietitian I appreciate your moderate use of salt, butter and maple syrup. Chock full of apples too. Great for any season.
    Thanks, Bella
