Rethink the way you enjoy sweet potato casserole with this fun twist! Captain Crunch casserole is full of creamy sweet potatoes and topped with a crunchy cereal topping. It’s the perfect side dish, especially on your holiday table.

forget the cereal bars or rice krispie treats, use cereal as a topping

Forget everything you know about sweet potato casserole. You might say that the gooey marshmallows on top is the best thing about it but I am about to change your mind!

The casserole base is the same as your normal sweet potato casserole but the topping is what really makes it.

Bits of sweet cereal mixed with light brown sugar and melted butter make a crunchy topping that is the perfect compliment to the creamy casserole underneath.

Give it a try and I promise you won’t miss the marshmallows!

Serve it any time of the year or during the holidays along with my pineapple casserole, onion casserole, mashed potato casserole, and this twice baked potato casserole.

Tips For The Best Casserole

Crush cereal in a food processor or in a plastic bag with a rolling pin. You want small pieces not dust.
Prep ahead of time and bake when ready.
Leave off topping until ready to bake so it doesn’t get soggy.
Substitute Kix or other corn cereal for the Cap’n Crunch.
Add in chopped toasted pecans if you like a nutty topping.
Use gluten free cereal for a gluten free dish!
