Health Benefits Of Eating Sweet Potatoes For Breakfast:

Sweet potato is a higher fiber lower glycemic root vegetable. It’s especially great when paired with the oats for even more fiber.

Any variety of sweet potatoes will work for this recipe as well. All sweet potatoes are high in nutrients and vitamins and are a great way to keep you full in the morning.

You can use roasted or boiled sweet potatoes for this recipe. Usually, I make this recipe whenever I have leftover smoked sweet potatoes or potato mash left.

I prefer sweet potato over pumpkin because it has a better flavor and texture, but you could use it as a substitute.

Can You Bake Oatmeal?

Yes, you can make oatmeal in your oven. Skip the stovetop version and try this baked oatmeal style casserole instead.

I find that it has a much better texture (similar to a bread pudding). It’s still soft and tender, but baking it allows it to be a little more spongey or cake like compared to whipping it up on the stovetop.

It’s an ideal breakfast recipe for meal prepping or serving for friends and family. This sweet potato casserole inspired version of this dish is also festive for the fall and winter time but tastes amazing year-round.


  • 2 1/4 cups Rolled Oats (not quick oats or steel cut)
  • 1 cup Mashed or Roasted Sweet Potato
  • 1 1/2 cups Oat Milk (or other preferred milk of choice)
  • 2 tbsp. Melted Butter (can sub with coconut oil
  • 1/3 cup Maple Syrup (can sub with honey, brown sugar, or a low carb sweetener like allulose)
  • 1 tsp. Baking Powder + Baking Soda
  • 1 tsp. Cinnamon
  • 1 tsp. Vanilla (vanilla helps amplify the flavor of the sweet potato)
  • 1/2 tsp Salt
  • Toppings (optional): Pecans, marshmallows, brown sugar, dried cranberries, white chocolate chips, or even some frozen blueberries.
Sweet Potato Baked Oats Ingredients


If you don’t have leftover mashed or baked sweet potatoes for this recipe, you will need to prep some. Take two small or one large sweet potato and slice it in half.

Place it in a pot and cover it with water. Bring the water to a boil and let it cook until soft, about 15-20 minutes. Remove the sweet potato and peel the skin. Mash with a fork and you’re ready to go!

To mix up these easy oven baked oats, add the warmed mashed sweet potato to a large mixing bowl. Whisk in the oat milk, melted butter, and vanilla.

Mixing the wet ingredients together for baked sweet potato oats

Once it’s fully combined, add in the dried rolled oats, the salt, cinnamon, and leavening agents (baking powder and baking soda). Fold the dried ingredients into the wet ingredients until everything comes together.

It’s ok if the sweet potato is slightly chunky as well, it will all bake together just fine.

Mixing Dry Ingredients together for baked sweet potato oats

Grease a 9×9 inch pan and pour the oat mixture into the pan and spread it evenly. If you want to add toppings, add in some whole pecans and sprinkle with a little brown sugar.

If you want to get into the sweet potato casserole vibe, I would also suggest adding a sprinkle of mini marshmallows over the top as well.

Baking Instructions:

  1. Preheat your oven to 350 degrees F.
  2. Place the pan of oatmeal into the middle rack of the oven and bake for 30 minutes. The oats should not be runny and the marshmallows should have puffed up and be golden brown (if you added them). Bake time may vary slightly if you use a different size pan or double the recipe.
  3. Remove and let the oatmeal cool for 5-10 minutes before slicing and serving. Slice the baked oats into 8 servings and pair with this sugar free ice oat milk espresso!

Storing And Reheating:

Store leftover baked sweet potato oats by covering them with plastic wrap or placing them into an air-tight container. They are best within 2-4 days but will keep for up to a week.

Reheat in the microwave to rewarm the oats as desired throughout the week for a quick breakfast on the go.

If you prefer to freeze any of the baked oats casserole, freeze each piece on parchment paper separately for an hour. Then place it in a bag. You can defrost it in the fridge for the upcoming week or place it straight into the microwave too.
