Peel the skin off of the sweet potatoes and boil in water for 30 minutes or until soft.
Preparing the Croquettes:
In a large mixing bowl add the sweet potatoes and mash with a fork. Next, add ½ cup of bread crumbs, mozzarella cheese, grated cheese, and 1 egg.
Mix all ingredients well and place in the refrigerator to cool for 1 hour. Remove potato mixture from refrigerator and form croquettes by molding two tablespoons of potatoes into oval shapes.
Place formed croquettes into the refrigerator overnight or the freezer for 2 hours.
Breading the Croquettes:
Prepare an egg wash. Whisk 3 eggs and ¼ cup of water together in a large bowl. Place 2 cups of bread crumbs into another large bowl.
Remove croquettes from refrigerator or freezer and dredge croquettes in flour than place in egg wash and then bread crumbs.
Place in egg wash and bread crumbs again to obtain a double coat of breadcrumbs.
Cooking the Croquettes:
In a large frying pan bring 1 cup of canola oil to a high heat.
Cook croquettes until golden brown, flipping as needed (3-5 minutes). Remove croquettes and drain oil.
To Serve:
Serve these simple sweet potato croquettes as an appetizer or a side dish.
Notes
Invent Your Recipe:A twist on the classic potato croquette, this recipe substitutes in sweet potatoes. For the traditional recipe, you can use yellow potatoes or red bliss potatoes.The ingredients in the mixture are up to you. The egg is not necessary, it just makes for a better binder when paired with the bread crumbs. If you choose not to use the egg or bread crumbs I highly recommend freezing the croquettes before you fry them. This will help to prevent them from falling apart in the oil.
