Crunchy Sweet Potato Casserole Recipe

In the same way that sweet potato casserole isn’t reserved for Thanksgiving, my kids like to eat cereal throughout the day. This served as the inspiration for our dinner plans this evening. People coat chicken and fish with crushed cereal, so I thought I would see what happens when you mix sweet potato casserole with cereal.

Back in 2016 I used a cereal as a topper, but most of the time I will just use marshmallows.  And not just any cereal, but versatile Post’s Honey Bunches of Oats cereals.

They come in a variety of flavors and complement many casseroles like Sweet Noodle Kugel, as a yummy topping. As an aside, I personally like to eat cereal out of the box as a snack, and Honey Bunches of Oats cereals have many different textures for your mouth to explore.

I like to microwave my sweet potatoes when making them to eat in their entirety or to smash for a casserole. I use the potato setting on my microwave (about 10 minutes).

Each microwave varies, so be sure to check your potatoes and turn over after five minutes.

If you make this recipe ahead of time, you can allow it to cool slightly, before covering and placing in your fridge. You’ll want to let it chill for about an hour before cooking.

Otherwise, bake your casserole for about 30 minutes. Then, it is time to cover your sweet potato casserole with the crunchy and sweet toppings that take it to a new level.
