Baked Sweet Potato Fries & Spicy Chili-Lime Mayo

Fries are only as good as their condiment – and this mayo is awesome!

Whenever my husband orders Sweet Potato Fries at a restaurant, he constantly raves about the flavor of the spicy mayo dip. After the last time, I had enough, and rolled up my sleeves and created my own gluten-free version for him to try.

After some trial and error, my husband now raves about MY dip!

  • 1 lbs sweet potatoes peeled & cut into 3/8-inch sticks
  • 2 Tbsp olive oil
  • Salt and pepper to taste

Spicy Chili Lime Mayo

  • 1/3 cup GF mayonnaise
  • 2 tsp GF ketchup
  • 2 Tbsp lime juice
  • Zest from 1 lime
  • 1/4-1/2 tsp chili powder or Sriracha to taste
  • 1/4 tsp salt
  • 1 Tbsp fresh cilantro finely chopped
  • 1/2-1 clove garlic minced
  • Dash of chili flakes optional


  • Slice the sweet potatoes plank-style, 1/4" thick by 1/2" wide. This gives more surface area to cook them, making them crispy instead of mushy-which tends to happen with this type of high-starch potato.
  • Soak the cut slices for 30 minutes in very cold water (with ice or in fridge) to remove as much starch as possible from their surface.. Drain and pat dry.
  • Toss the sweet potatoes with the oil, salt, and pepper, and spread in an even layer on a preheated baking pan or a baking stone (for crispier fries).
  • Bake at 400°F for about 40 minutes, turning a few times to ensure even browning.
  • Remove from the oven and sprinkle with a bit of coarse sea salt if desired, and serve with mayo.
  • To prepare spicy mayo, whisk all ingredients together until smooth.
