Sweet Potato Fries

  • 860 g Sweet Potatoes
  • 2 tbsp Olive Oil
  • 1 1/2 tsp Salt
  • 2 tsp each Pepper, and Thyme
  • 1 tsp Chipotle Powder

Homemade Spicy Mayo

  • 1 Egg
  • 1/4 cup Chili Oil
  • 2/3 cup Olive Oil
  • 1 1/2 tbsp White Wine Vinegar
  • 1/4 tsp each Thyme, Basil, Salt, Pepper, Cumin


  • Heat the oven to 400F. Line two baking sheets with parchment paper.

Sweet Potato Fries

  • Cut the sweet potatoes into 1/2" thick wedges.
  • In a large bowl, combine the sweet potatoes, oil, and spices. Toss together to coat fully.
  • Spread the wedges out, evenly spaced apart, onto the two trays. Give them plenty of space for that they don't overcrowd each other.
  • Bake for 12 minutes, then flip. Bake for another 10-12 minutes, or until crisp and lightly browned on the outside, and soft all the way through.

Spicy Mayo

  • While the fries are cooking, prepare the mayo. To the mixing cup of an immersion blender, add the egg and chili oil.
  • Begin blending the egg and oil. Next, in a slow, steady stream, pour in the olive oil, while blending continuously. It will become very thick.
    If you have a second pair of hands to help you with this, it can be useful to have them hold the cup.
    If using a traditional blender, start blending the egg and chili oil, then stream in the olive oil into the blender while it's running.
  • Blend in the vinegar. The vinegar will loosen up the mayo. Add the spices, and season to taste with salt and pepper. At this point you should adjust the mayo to your tastes. More vinegar or spices can be added depending on what you like.
  • Serve the fries, hot, alongside the mayo. Enjoy!
