Tips for the Best Sweet Potato Casserole

Bake the Sweet Potatoes

Bake the 8 sweet potatoes in the oven. If you are in a pinch for time, you can totally microwave them. I think the flavor is better when you bake them. But honestly, the difference is very minor so microwaving is definitely an option.

Be sure to wash and puncture sweet potatoes with fork holes all over, both for the oven or microwave method.

Place potatoes on a baking sheet and pop in the oven for 1 hour at 400 degrees.

Blending the Bottom Layer

When mixing the bottom layer of sweet potatoes, softened butter, sugar and eggs use a hand mixer on low. Consistency will be thick but spreadable. Then, pour and spread in the bottom of a baking dish. Glass or metal is fine.

What Gives the Awesome Crunch?

What really makes this sweet potato casserole stand out? The amazing CRUNCH! Your typical sweet potato recipe is adorned with marshmallows, which is okay but I’m a sucker for the crunch in this recipe! The crunch comes from the combination of toasted corn flakes and pecans. While this dish bakes in the oven, the brown sugar melts coating the pecans and corn flakes. The result is out of this world good!

For the top layer you will want to mix by hand with a spoon. I like to mix it with the melted butter fairly warm so it combines well with the sugar and other ingredients. Spread the top layer over the bottom layer of sweet potatoes.

Then pop in the oven for about 30 minutes or until golden brown. And voila! Now you have a gorgeous sweet potato casserole dish that is really the best. Ever.
