Crumble Topped Sweet Potato Casserole

Crumble Topped Sweet Potato Casserole

I know we are all used to seeing that classic sweet potato with mini marshmallows on the Thanksgiving dinner table, but once you have sweet potato casserole with crunchy topping, you won’t turn back. My Crumble Topped Sweet Potato Casserole has a fluffy sweet potato mixture combined with a sweet, salty and crunchy topping.

Crumble Topped Sweet Potato Casserole Tips

You want to bake the sweet potatoes. This just creates a fluffier texture for your casserole. You need them fork tender. We are talking super soft sweet potatoes here.

You’ll let those cool so you can handle them and put them in a large bowl and use a potato masher to mash them smooth. I really like to whip them in my stand mixer, but if you don’t have one, this will be fine. A hand mixer works too!

The maple syrup adds a touch of sweetness, but not too much. While it’s a pricier ingredient, I highly recommend it. Make sure it’s pure maple syrup and not your morning pancake syrup.

The crunchy pecan crumble has an unexpected ingredient, corn flakes! The corn flakes get extra crispy in the oven and they create that sweet and salty crumble texture you’re after. The butter is essential here to facilitate flavor and that crunchy texture. The food processor makes quick work of the crumble, but if you don’t have one, just put the pecans and corn flakes in a zip top bag to crush them. Beat them with a rolling pin or mallet. Get those aggressions out before family arrives 😉

If you use the zip top bag method, simply add the butter in by cutting into small pieces and sprinkle it over the top of the casserole. It will be just as tasty and golden brown! This delicious sweet potato casserole is hard to mess up!

I like to bake this in a cast iron skillet, but your favorite casserole dish will work too!

One of the best part about this sweet potato casserole is that it’s just as delicious at room temperature. Ovens and space is always challenging at the Thanksgiving table so recipes like this are the best.

Another bonus – this recipe is perfect when assembled ahead of time. Just get it ready to go in the oven, but refrigerate and bake it fresh the next day.

Sweet Potato Casserole Substitutions

First off fresh sweet potatoes or real yams are a non negotiable. The flavor and texture of canned ones just will not do here.

There are few subs for this easy sweet potato casserole, but I’ve put together a few so this can be allergy friendly. Nuts are sometimes an issue, so if you can’t do those, just use all corn flakes in the pecan topping. I already recommend almond milk for the dairy, so again if nuts are a thing, just use any milk you can handle.

Inevitably someone will ask me about cutting sugar etc. Listen, it’s Thanksgiving. I wrote this recipe to be far healthier than the family favorite, but I still wanted it to be the best sweet potato casserole recipe it can be. Good food requires some fat and sugar. Make these kinds of substitutions at your own peril.

But also ask yourself what is a “healthy lifestyle” if it can’t include one day of indulgence with your family. In fact, if you have some from leftover from other recipes, don’t buy another kind of milk, just use that heavy cream.

Thanksgiving day was meant to be enjoyed so enjoy.

Storing Leftovers

Assuming you have any? Simply store your leftovers in an airtight container and reheat in the microwave or oven. They will keep for 3-4 days as any other leftovers like this will. The best part? Those corn flakes really keep it crunchy so it still has great flavor!

Mashed Sweet potatoes, crumb topping…. I just don’t see leftovers being an issue here.

Calories 147 kcal


  • 1.5 cups Corn Flakes Cereal
  • 1/3 cup Pecans
  • 4 tbsp. Butter Cold, diced into small cubes
  • 4 tbsp. brown sugar divided- half for topping and half for filling
  • 1/2 tsp. salt divided- half for topping and half for filling
  • 4 large Sweet Potatoes Baked or Microwaved
  • 1 large egg
  • 1 large Egg White
  • 1 tsp. cinnamon
  • 1/4 cup Maple Syrup
  • 1/4 cup unsweetened vanilla almond milk


  • Preheat oven to 400 degrees. You can bake or microwave your sweet potatoes. I find that this casserole is fluffier if I bake them, but the difference is minimal. Do whatever works for you time wise.
  • In the bowl of a food processor pour in the corn flakes, pecans, butter, 2 tbsp. of brown sugar and 1/4 tsp. of salt. Whirl it up until it forms a nice crumble texture. The butter will evenly distribute throughout.
  • Set the crumble aside and prepare to mix the filling. You can do this in a stand mixer or with a hand mixer.
  • Make sure the sweet potatoes are cooled. Scoop out the flesh of the sweet potatoes and then add the egg, egg white, cinnamon, brown sugar, maple syrup, 1/4 tsp. salt and 1/4 cup of vanilla almond milk. Beat on medium high speed with a whisk attachment until fluffy.
  • Butter a 10 inch cast iron skillet or an 8x8 baking dish. Pour the filling in, then spread the crumble topping over it. Bake for 25-30 minutes or until the top is golden and everything is warmed through.


Make it Gluten Free: Make sure your corn flakes are certified gluten free and this is a gluten free crumble topped sweet potato casserole you can enjoy.
