Inspired by my favorite fall casserole, this sweet potato baked oatmeal is loaded with sweet potato goodness and topped with a crispy pecan topping. It’s also vegan and gluten-free.

This month’s baked oatmeal flavor is inspired by my absolute favorite Thanksgiving dish – sweet potato casserole. When brainstorming baked oatmeal recipe ideas for November I thought, why not take the main flavors from my favorite dish and turn them into a baked oatmeal?

Now I get to enjoy one of my holiday faves all year long… and for breakfast, nonetheless.

Baked Oatmeal FAQs

Before we dive into the recipe, I wanted to address some FAQs I’ve been getting about baked oatmeal!

Why almond milk? I personally love the flavor and nutrition stats for almond milk. That said, you can absolutely swap in your preferred milk of choice. Cow’s milk, cashew milk, oat milk, rice milk, soy milk… really any type of milk will work for baked oatmeal.

Why rolled oats? Rolled oats absorb more liquid than other types of oats and hold up well during cooking. I would not recommend using different oats unless the recipe calls for a specific kind of oat. I do have a delicious baked steel cut oatmeal recipe!

Can I prep at night and bake in the morning? Yes, you can totally do this to save on time, but I personally like to prep and bake it all at once because the oats do tend to soak up quite a bit of the milk overnight (kind of like overnight oats). If you don’t have a choice and need to prep the oatmeal bake ahead of time, that’s fine. It might just seem a little bit drier than normal after baking. If this happens, just serve with a splash of milk.

Another prep-ahead option is to combine all the dry ingredients in a bowl and combine the wet ingredients in a separate bowl the night before. The morning of, simply mix the two together, pour into your baking dish and bake!

Crispy Oatmeal Pecan Topping

In my opinion, the topping is what makes sweet potato casserole so yummy, so of course I had to include it in this baked oatmeal recipe.

The oatmeal topping is made of coconut sugar (or brown sugar), chopped pecans, rolled oats and coconut oil. Mix the ingredients together and sprinkle on the oatmeal bake before baking. The end result will be a crispy, crunchy topping that’s simply irresistible.

Flavor Variation

Not a sweet potato fan? You can use pumpkin instead! Use 1 cup of pumpkin puree (not pumpkin pie filling) in place of the mashed sweet potatoes. Mmm…

  1. For Lent this year I am following a No Food Waste program (that and the current restrictions, really make me focus on no waste) There is a cup of butternut squash leftover from the other night–Not really enough for the two of us so I’ll freeze it. When I am able toto get more milk, I certainly will try this.

  2. I’ve been looking for an oatmeal breakfast “on the go” and out of 4 recipes I’ve tried out, this is the only one I really like. The texture is very pleasant and it’s tasty. This will definitely become a regular breakfast for me, and a nice reason to get up in the morning 🙂

  3. Brittany have you baked this in muffin cups? I want to make breakfast foods grab and go.
    I have two preschooler granddaughters who eat on the run (literally) and they love anything made into Muffins:)

  4. I felt like I won the lottery when I saw this recipe posted and knew I had a cup of mashed sweet potato leftover in my fridge! I love every baked oatmeal variation and this one is a fantastic addition 🥰

  5. Hey! I would love to make this as a breakfast prep ahead of time for when my baby comes! I’m deep in the cook & freeze mode!
    Wondering if it’s best to freeze, then thaw and bake, or bake then freeze ? Looking for tastiest reheat option in the oven!
