What makes this sweet potato casserole healthy and yet so good?

  • Instead of mixing tons of butter into the sweet potatoes, we add some almond milk to get the perfect amount of moisture. You only need 3 tablespoons of butter for this delicious crumb topping, but you can also use vegan butter or coconut oil.
  • The sweet potato mix is ​​only sweetened with a little pure maple syrup.
  • We’re skipping the marshmallow topping and adding a crispy, addicting pecan oatmeal topping instead. YUM!

I’m not going to lie, there have been many times I’ve preferred this as my Thanksgiving dessert because it’s so delicious. Pour some whipped cream over it or serve with vanilla ice cream and you’re done.

Healthy ingredients for the sweet potato casserole

This incredible, healthy sweet potato casserole recipe is easy and delicious. You basically need sweet potatoes, spices, oats, and pecans to make the whole thing. So easy! Here is everything you need:

  • Roasted Sweet Potatoes: This recipe starts with roasted sweet potatoes, which are crucial in keeping the casserole sweet, creamy, and tasty without the need to use a ton of excess sweeteners. The good news is that you can roast them ahead of time! They take an hour, so I like to bake them a few days beforehand, then wrap them in foil and keep them in the fridge until baked. Advancing them is optional.
  • Pure maple syrup: I love adding pure maple syrup to the sweet potato filling. It’s only 2 tablespoons so feel free to use honey, but I ALWAYS choose maple.
  • Almond milk: some almond milk will help smooth things out and make the sweet potato filling super creamy. Feel free to use whatever milk you want. I also think coconut or cashew milk is delicious!
  • Egg: I usually add 1 egg to the sweet potato mixture for a little more moisture. Feel free to leave it out if you are a vegan.
  • Spices: Add some cinnamon, nutmeg, and a hint of allspice to get just the right flavor.
  • Pecan Oatmeal Crumble: Who doesn’t love a crispy oat topping? This one contains a little butter, brown sugar, whole wheat flour, oatmeal, and sweet pecans! Trust me it’s fabulous.

Simple ingredient swap

From a few ingredients? No problem! This sweet potato casserole is easy to personalize:

  • For the butter: Feel free to subtract coconut oil or vegan butter.
  • For the brown sugar: You can also use coconut sugar or make your own brown sugar with this tutorial!
  • For the flour: If you don’t have whole wheat flour, you can use regular all-purpose flour. See below for a gluten-free option.

Simply prepare dairy-free or vegan

Right, you can easily make a vegan sweet potato casserole out of it! Use coconut oil or vegan butter instead of regular butter in the topping to keep it dairy-free; and if you’re vegan, skip the egg in the sweet potato mixture. It will still be delicious!

How to make sweet potato casserole in advance

Here’s some good news: Not only is this SIMPLE recipe, but you can make it a day in advance if you want. Simple:

  1. Prepare the recipe as directed.
  2. Cover with foil and put in the refrigerator.
  3. After preparation, bake and serve as directed!

As mentioned earlier, you can also roast your sweet potatoes in advance. They take an hour so I like to bake them a few days beforehand, then wrap them in foil and put them in the fridge until the casserole is done. I am always happy when I can save as much time as possible on Thanksgiving, because it leaves more time for wine and good conversations with the people you love.

  4. Slice and peel the sweet potatoes, place the sweet potato meat in a large bowl and add the maple syrup, almond milk, vanilla, egg, cinnamon, nutmeg, allspice and salt. Use an electric mixer to whip until smooth and add a squeeze more almond milk if you want them to be creamier. Pour into the prepared baking pan and smooth out.

  5. For the topping: whisk together the flour, oatmeal, brown sugar and pecans. Stir in melted butter with a fork until a nice crumb is formed. Sprinkle everything over the sweet potato mixture.

  6. Bake for 25-30 minutes or until the top is lightly golden brown. Take out of the oven and let cool for 5-10 minutes. Serves 8.
