How To Prep Your Sweet Potatoes

One of the keys to making killer sweet potato fries is the prep. You may have tried this dish in the past and ended up with a soggy, flavorless “fry” that turned you off from ever wanting to try it again. No more! Truth be told, sweet potato fries can be a little finicky, but we all deserve a little TLC sometimes. These tips will help you achieve much crispier and tastier fry:

  1. Peel your raw sweet potatoes and slice them into 1/4 inch matchsticks. We like to slice the sweet potato into thin lengthwise sections first, and then slice the sections into the long matchsticks.
  2. Soak the sliced sweet potatoes in cold water for a minimum of 1 hour. You can even soak these babies overnight. Is this time-consuming step necessary? Yes, if you want a crispy sweet potato fry. The goal is to pull out the excess starch from the sweet potatoes. Trust us, it's worth it.
  3. Rinse the sweet potatoes and pat dry.
  4. Add two large handfuls of fries to a large plastic bag plus two teaspoons of starch and shake vigorously. Do this until all the fries have been coated in a very light layer of starch. You can use cornstarch, tapioca starch, brown rice starch, or a combination of the three.

Ok, now that your sweet potatoes are prepped, it's time to get cooking!

Sweet Potato Fries In The Oven

No deep fryer? No problem! You can still make tasty, crispy fries by baking them in your oven!

To start, preheat your oven to 425 degrees.

While the oven is heating, you'll want to toss your sweet potato fries in some oil. We recommend using grapeseed or canola oil instead of olive oil. Grapeseed and canola have a higher smoke point, which is important considering the heat required to crisp these babies up.

You'll also be tempted to add salt at this point, but don't do it yet! Save that for after they are baked.

Next, line a sheet pan with heavy-duty aluminum foil sprayed with a little bit of non-stick cooking spray. You'll then want to lay your sweet potato fries in a single layer with a good amount of space in-between. This is another important step to achieving a crispy fry, so don't skip it! If the fries are too close or touching the sweet potatoes will actually steam instead of bake, resulting in a sad, soggy fry.

Allow the fries to bake for 30 minutes, flipping halfway through. Let cool on the pans for at least 10 minutes before tossing in salt and/or other seasonings.

Sweet Potato Fries In The Air Fryer

Remember the days before air fryers were a thing? How did we survive?! An air fryer is a fantastic way to make sweet potato fries!

Follow the same prep instructions outlined above, and preheat your air fryer to 400 degrees.

Once heated, place the fries in the basket of the air fryer. Just like in the oven, you don't want to crowd them, so you may want to do this in batches so there is plenty of room for air to circulate around the fries.

Cook the fries for about 10 minutes, shaking the basket halfway through. Since there is some variation between air fryers, you may find that you need more or less time depending your desired level of crispiness.

Remove from the air fryer, toss with salt, and enjoy!

Sweet Potato Fries In The Deep Fryer

If you are one of the lucky souls to own a deep fryer, you have some delicious sweet potato fries coming your way!

To make sweet potato fries in the deep fryer, prep your fries as outlined above up to step 3.

Then, create a batter for your fries by combining cornstarch with either water or club soda using a 1:1 ratio. Dip the fries in one or two at a time and add to the hot oil.

Keeping your oil at the right temperature is an important part of creating a yummy fry. We recommend using peanut oil heated to 325 degrees. A deep fry thermometer is a great tool to make sure this process goes smoothly.

Fry each batch for about 1-2 minutes, then remove, salt, and devour! Yum!

Variations For Sweet Potato Fries

Sweet potatoes pair well with a variety of flavors! As mentioned previously, you'll want to reserve seasoning with salt until after the fries are cooked. However, when shaking with starch or creating a batter, feel free to add seasonings such as paprika, cayenne pepper, chili powder, chipotle powder, black pepper, or garlic powder.

You can also add seasonings after cooking, specifically herbs. Try adding chopped rosemary, thyme, dill weed, or Italian seasoning for a fresh twist of flavor!
