Apple Pie Baked Oatmeal | Kara Lydon

Perfect for the fall, this apple pie baked oatmeal is a cozy, delicious make-ahead breakfast for the week. Made with diced apples, rolled oats, maple syrup, cinnamon, nutmeg and ginger, it’s reminiscent of warm apple pie flavors!

Why I Love This Recipe

This Apple Pie Baked Oatmeal is a perfect warm and cozy breakfast that will give you all the fall warm and fuzzies. 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. 

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.

Ingredients You’ll Need

Notes on Ingredients

apples: I like to use Honeycrisp apples but any variety will work in this recipe. No need to peel the apples unless you prefer it

rolled oats: oats are a nutritious whole-grain rich in many vitamins and minerals. I recommend using old-fashioned rolled oats here but if you want to make a gluten-free version, be sure to use certified gluten-free rolled oats. Rolled oats are naturally gluten-free but if they are manufactured in a facility that produces gluten it may have trace amounts so if you have a gluten allergy (Celiac disease), you’ll want to find certified gluten-free oats.

butter: acts as a flavor enhancer and helps to give a smooth texture

eggs: binding ingredient to hold everything together

maple syrup: adds a touch of sweetness 

vanilla: also provides some sweetness

almond milk: you can use any type of regular dairy or non-dairy milk in this recipe. I like using almond milk for it’s mild, neutral taste

pumpkin pie spice: gives all the warm, cozy fall flavor! It’s typically made up of cinnamon, nutmeg, ginger, cloves and allspice 

baking powder: helps the oats rise in the oven and lightens the texture 

salt: enhancecs the flavor 

walnuts: add a little monounsaturated fat and plant-based protein boost, bumping up the satiety factor of this breakfast

Expert Tips

1. Make this a make-ahead breakfast! Mixture can be made ahead of time (like on a Sunday!) and stored overnight in the fridge. Let sit out at room temperature while the oven preheats and stir mixture before baking. Bake in the morning and you’ve got breakfast for the entire week! 

Recipe FAQs

What type of apple is best?

Personally, I like to use Honeycrisp apples because they’re both a little sweet and a little tart but any type of apple will be delicious. I opt not to peel my apples to save some time but you can certainly peel them if you prefer. 

How do you reheat baked oatmeal?

Baked oatmeal can be reheated in the microwave for 1 minute with a little splash of almond milk or milk or in the toaster oven for a few minutes. I find that the splash of milk keeps the oatmeal moist and prevents it from drying out. 

What toppings should I use on baked oatmeal?

You can jazz up your baked oatmeal with a variety of toppings. Think a dollop of whipped cream or yogurt, a drizzle of maple syrup, honey, or nut butter, a dash of cinnamon, more diced apples, or dried cranberries or raisins. 

Storage and Preparation

Apple Pie Baked Oatmeal leftovers can be stored in an airtight container in the refrigerator for up to 4 days. Reheat in microwave for 1 minute with a little splash of almond milk or milk.

Baked oatmeal is also freezer-friendly. To store in the freezer, bake as directed, let cool completely, then store in an airtight container in the freezer for up to 3 months.
