“Better than Sweet Potato Casserole” CRISPY Sweet Potato Fritters

These crispy sweet potato fritters, known as tortitas crujientes de boniato, are seriously some of the best fritters I have ever tasted. We’re talking a light crispy texture with a delicious interior, easy to make, and all done in about 30 minutes. Serve them as a tapas appetizer or even as a side dish.

CRISPY Sweet Potato Fritters

To make this recipe, I left the skins on the sweet potato. As it adds more nutrients and flavors. If you prefer, you can peel it. Either way, once you shred the sweet potato, make sure to add it over a cheesecloth or flour sack towel and squeeze out any of the water. This will ensure you achieve that crispy texture.

I served these fritters next to a simple yet delicious mayo aioli. Made with just garlic, saffron, mayonnaise, Dijon mustard, lemon juice, and olive oil. You can also add in a dash of crushed red pepper for a spicy kick if you like.

TIPS & TRICKS to Make this Recipe: For the batter, I used beer. You can also use club soda or sparkling water. If you see your batter is too thick, just add in some whisked egg or more liquid. You can also make the batter ahead of time. It will hold for up to 2 to 3 days in the fridge in an airtight container.

Instructions

TO MAKE THE SWEET POTATO FRITTERS

  1. Using a box grater, finely shred the sweet potato, then add over a cheesecloth with a bowl underneath, and squeeze out all the water

  2. Add the flour and baking powder into a large bowl, whisk together, then make a well in the middle, crack in the egg and whisk the egg, and then add in the beer and whisk everything together until you get a smooth batter

  3. Add the shredded sweet potato into the bowl with the batter, along with the chopped onion, grated garlic, grated cheese, chopped parsley, paprika, cumin, and season with salt & pepper, mix together until well mixed and you end up with a paste-like texture, add in some whisked egg if it looks to dry

  4. Heat a large fry pan with a medium heat and add in the olive oil

  5. After a couple of minutes and the oil is nice and hot, start adding in spoonfuls of the batter and gently pushing down on each one, you want all the fritters in a single layer and evenly spaced, so cook in batches to not overcrowd the pan, fry for 3 to 4 minutes per side or until golden and crispy, then transfer into a dish with paper towels

TO MAKE THE MAYO AIOLI

  1. Add the chopped garlic into a mortar, along with the saffron, and a pinch of salt, using a pestle pound down on the ingredients until you get a paste-like texture, then add in the mayonnaise, dijon mustard, lemon juice, olive oil, and season with salt & pepper, whisk together

  2. Add the mayo aioli into a serving dish and decorate the fritters around it, garnish with chopped chives, enjoy!
