How to Make Baked Sweet Potato Wedges and the Cilantro Cashew Sauce:
Recipe Ingredients:
Here’s everything you’ll need to make this sweet potato wedges recipe. See the recipe card below for the exact quantities.
Ingredient Notes and Substitutions:
- 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 that are firm and 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 remove them if you don’t want that much spice. 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 cuisines 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.
- Roast for 20 minutes. Flip, then roast for another 20 minutes or until cooked through and lightly browned.
- MAKE AHEAD: The potatoes can be roasted one day ahead of time to this point. Be careful not to overcook or overbrown them. Refrigerate until needed.
- That’s it!
- Serve the oven-roasted sweet potato wedges immediately topped with the spicy, savory, crunchy Cilantro – Cashew Sauce!
- Enjoy!! The sauce is also amazing over a baked sweet potato, too!
Chef Tips and Tricks:
- Don’t crowd the potatoes when making any type of potato wedges recipe. If crowded, they steam instead. Make sure one of the cut sides is touching the pan.
- Cut the sweet potatoes into cubes and toss them with a spatula or large spoon to speed up the roasting process. You can also do sweet potato fries.
Recipe FAQs:
