Sweet Potato Casserole with Crunchy Pecan Topping

This warm, smooth and fluffy sweet potato casserole has a delightfully crunchy topping that features cinnamon, brown sugar and pecans. The combination of textures is seriously to die for – as you munch on the crispy, buttery topping, the soft sweet potatoes melt in your mouth. And putting it all together couldn’t possibly be more simple.

Even though this side dish is on the sweeter, more indulgent side, it’s still a healthy recipe to serve your family. The sweet potatoes contain tons of vitamins, nutrients and beneficial plant compounds, while the pecans are a great source of minerals like calcium, potassium and magnesium.

So even though this casserole may taste like a dessert, it’s going to nourish your body and keep you satisfied. And that’s what Thanksgiving is all about!

How to Make Sweet Potato Casserole

Before you start on your filling, you will need to bake and mash up the sweet potatoes. Once they are prepared, you’ll have to bake them once more with the streusel on top.

Make the Filling

Heat Oven: Preheat the oven to 400°F.

Poke Potatoes: Use a fork to prick the sweet potatoes a couple of times on all sides.

Bake: Bake the poked potatoes on a lined baking sheet for 40 minutes.

Turn Oven Off: After 40 minutes, turn off the oven and let the sweet potatoes sit inside for an additional 30 minutes.

Remove from Oven: Remove the sweet potatoes from the oven and let them cool.

Peel Potatoes: Remove the potato skin and place the flesh into a large bowl.

Add Remaining Ingredients & Mash: Next, add in the melted butter, maple syrup, vanilla, egg and almond milk. Mix everything together with a hand blender until the potatoes are creamy and smooth.

Heat Oven: Preheat the oven to 350°F.

Assemble in Pan: Transfer the prepared filling to an 8×8-inch glass pan and sprinkle the pecan streusel overtop.

Bake: Bake the casserole uncovered for 45 minutes, or until the topping is browned.

Enjoy! Serve warm.

Can I Make This in Advance?

If you’d like, you can make your sweet potato filling a day or two ahead of time. Just store it well-covered in the fridge until you’re ready to make your topping and bake.

Tips for Success

You’re almost ready to make the best sweet potato casserole you’ve ever tasted! These tips and tricks will make the process even simpler.

  • Don’t Forget to Prick the Potatoes: Poking small holes into the potatoes before you bake them is a very important step. It prevents them from exploding in the oven, as it allows the steam to escape while they cook.
  • Peel After Cooking: While it’s okay to peel the potatoes before you bake them instead of afterward, I don’t necessarily recommend it. They are so much easier to peel after they’re cooked.
  • Bake or Boil: This recipe instructs you to bake the sweet potatoes before mashing them, but you can choose to boil them instead if you’d like. As long as your sweet potatoes are fork tender and mash-able, any cooking method will suffice.
  • Avoid Over-Browning: If you find that your streusel topping is browning too quickly, simply tent a piece of foil over the baking dish to stall the browning process. You could also use a pie shield if you have one.

Variation Ideas

There are plenty of ways to make adjustments to this festive side dish. Get a load of the tasty variation options below!

  • Marshmallow Topped Sweet Potato Casserole: Many people prefer a fluffy marshmallow topping to a crunchy pecan one when it comes to their sweet potato casseroles. If this sounds like you, feel free to forego the streusel topping for mini marshmallows. Bake the casserole until the marshmallows puff up and start to brown.
  • Spiced Sweet Potato Casserole: If you want to incorporate even more holiday goodness into this dish, you can add spices like cinnamon, nutmeg, cloves and allspice to the filling.
  • Bacon Topped Sweet Potato Casserole: Craving some savory bacon with your sweet potato casserole? Feel free to substitute the pecans in the topping for cooked bacon bits. Cook the bacon slightly less crispy than you like it since it will crisp up as the casserole bakes.
  • Corn Flake Topped Sweet Potato Casserole: Corn Flakes have recently become quite a popular topping for sweet potato casseroles. If you’d like to try this new-wave variation, just substitute the pecans for Corn Flakes. You could even leave off the topping in favor of a generous layer of Frosted Flakes, if desired.

How to Store Leftovers

Refrigerate leftover casserole in an airtight container once it has cooled completely (don’t leave it at room temperature for longer than 2 hours). It will stay fresh in the fridge for up to 5 days.

To reheat it, place it in a 350°F oven for about 15 minutes. Make sure you cover it with foil to keep the topping from over-browning. Small portions can be reheated in the microwave.

Can I Freeze Sweet Potato Casserole?

Yes, you can freeze leftover casserole for up to 4 months. Place it in a freezer-safe container or cover it with two layers of plastic wrap. Thaw it out overnight in the fridge before reheating it.

  1. I’ve never made a sweet potato casserole but this one sounds good with the pecan crust. Much better than marshmallows.
