Ingredients for Roasted Sweet Potato Wedges with Cilantro - Cashew Sauce.

Ingredient Notes:

Sweet Potatoes: Sweet potatoes are available all year round but their peak season is from late summer to early winter. When buying them, look for smooth skins with no discoloration and that are firm and feel solid. Choose orange or red-skinned sweet potatoes which tend to be more moist and less starchy than other varieties. I used medium sweet potatoes.
Serrano Chiles: Serrano peppers are hot chile peppers named for the mountain ridges in Mexico where they originated. They’re second to the jalapeno pepper in popularity there but are hotter than jalapenos. They are also used in Southeast Asian cuisine. Most of the heat is in the seeds and membrane so if you don’t want that much spice, remove them. I highly recommend you wear gloves when handling serranos and be careful not to touch your eyes or other sensitive areas.
Fish Sauce: Fish sauce is a condiment made from fish that has been coated in salt and fermented for up to two years. It’s very popular in Southeast Asian cuisine like Thai. Vegan Alternative: Use soy sauce, mushroom broth or this Vegan Fish Sauce from Vegan24.
Cashews: You may also use peanuts.

Step-By-Step Instructions:

Gather and prep all the ingredients.
Preheat your oven to 425 degrees.
Start by making the Cilantro Cashew Sauce. Place all the ingredients EXCEPT the cashews into a food processor or blender. Process until smooth.

Transfer to a bowl then stir in the chopped cashews. (They won’t soften up all that quickly.) Set aside.
MAKE AHEAD: The Cilantro Cashew Sauce can be made one day ahead. Refrigerate until needed. Don’t add the cashews until ready to serve.

Peel the potatoes if desired and cut them into 6 to 8 wedges each, keeping them as uniform as possible.
Place the wedges on a cast iron baking pan such as the one shown below or line a rimmed baking sheet with nonstick aluminum foil or parchment paper.

MAKE AHEAD: The potatoes can be roasted one day ahead of time to this point. Be careful to not overcook or over brown them. Refrigerate until needed.

Chef Tips and Tricks:

When doing any type of potato wedges recipe, don’t crowd the potatoes. If crowded, they steam instead. Make sure one of the cut sides is touching the foil.
To speed up the roasting process, cut the sweet potatoes into cubes and toss them with a spatula or large spoon. You can also do sweet potato fries.

Frequently Asked Questions:

Can I make sweet potato wedges in an air fryer?

Yes, absolutely! Preheat your air fryer to 350 degrees. Arrange the sweet potato wedges in the basket or on the rack. Make sure they’re not touching. Cook for 8-10 minutes, flip then cook another 4-5 minutes. You may need to cook them in batches.

Can I roast sweet potato wedges ahead of time?

Yes, you can. Be careful to not overcook or overly brown the sweet potatoes when roasting the first time. To reheat, place on a baking sheet and reheat at 350 degrees.

Can you eat sweet potato skins?

Yes! Whether you peel sweet potatoes is entirely up to you. Be sure to scrub them well if you intend to. Sweet potato skins are rich in fiber to increase feelings of fullness and manage blood sugar and cholesterol, support a healthy gut and nutrients and antioxidants to prevent chronic disease.
