low carb sweet potato recipe

Brown Butter Roasted Sweet Potatoes

While sweet potatoes aren't 100% keto-approved, they do fall on the lower end of the glycemic index and are packed with health benefits, so I'm including this delicious recipe on my keto menu as a bit of a cheat that is well worth it in terms of flavor and nutrition.

  • 4 pounds sweet potatoes peeled and cut into bite-sized cubes
  • 1/4 cup brown sugar substitute I like Swerve Brown or Lakanto Golden sweetener
  • 1/2 cup unsalted butter
  • 1 tablespoon fresh thyme leaves
  • 1 teaspoon fresh sage julienned (cut in thin strips)
  • salt and pepper to taste


  • Preheat oven to 400℉
  • Add sweet potatoes and brown sugar substitute to a bowl and toss to coat.
  • Heat the butter in a saucepan over medium heat until it melts and then starts to brown...make sure to keep an eye on it so it doesn't burn. This will take about 5 minutes.
  • Remove browned butter from heat and add thyme and sage.
  • Add the butter mixture to the bowl and toss to coat.
  • Season with salt and pepper.
  • Lay the potatoes in a single layer on a prepared baking sheet.
  • Roast for 45 minutes until the potatoes a soft and glossy.
  • Season with salt and pepper and serve!
