Candied sweet potatoes have been a holiday staple for generations, gracing Thanksgiving and Christmas tables across the U.S. with their irresistible blend of natural sweetness and caramelized glaze.

Candied Sweet Potatoes, Reinvented

But wait...there’s more! Let me spill some tea on the latest trends shaking up this classic dish. In Japan, chefs are using miso-caramel sauce to give candied sweet potatoes an umami-rich, savory-sweet twist. Meanwhile, in Mexico, brown sugar is swapped out for piloncillo, and a touch of ancho chili adds smoky, spicy magic. (Whoa...mind blown, right?)

So, why stick to the same-old recipe? With these creative ideas, you can craft a dish that’s anything but ordinary. I mean...isn’t it time to shock everyone at the dinner table?

Let’s do this!

Storage & Serving Suggestions

Let’s make sure you get the most out of your Keto Candied Sweet Potatoes...

Storage Tips

  1. Refrigerate the Leftovers
    • Got extras? (Lucky you!) Store them in an airtight container in the fridge for up to 4-5 days.
  2. Reheat Like a Pro
    • Pop your leftovers in the oven at 350°F (175°C) for about 10-15 minutes to bring them back to their warm, gooey perfection. Microwave works too... but the oven keeps those textures just right.
  3. Freeze for Later
    • Planning ahead? Freeze this dish in a freezer-safe container for up to 3 months. Just skip the marshmallow topping and add it fresh when reheating.

Serving Tips

  1. Perfect Pairings
    • Serve these alongside roasted turkey, glazed ham, or a keto-friendly main dish like garlic butter steak. It’s the ultimate holiday (or anytime) sidekick!
  2. Top It Up
    • Sprinkle some extra cinnamon, a few crushed pecans, or even a dollop of keto whipped cream for an indulgent twist.
  3. Make It a Meal
    • Add some crispy bacon crumbles on top and turn this into a hearty side that could almost double as a main dish.
  4. Serve Fresh and Hot
    • This dish tastes best when served straight out of the oven... because who doesn’t love gooey marshmallows and warm caramel sauce?

Your leftovers will be just as delicious, but honestly... don’t expect too many of them. 😉

Tips & FAQs

Why should we boil sweet potatoes before baking?

Boiling sweet potatoes before baking isn’t necessary... but it depends on the dish you’re making. For candied sweet potatoes, skip boiling. Roasting brings out their natural sweetness, creates caramelized edges, and keeps the dish rich and flavorful. Boiling, while faster, can make sweet potatoes waterlogged, reducing the depth of flavor.

That said, if you're making mashed sweet potatoes, boiling works beautifully. Want to save time? Try steaming instead—it’s quicker and helps retain nutrients!

Why don’t sweet potatoes get crispy?

Sweet potatoes can be a little tricky to crisp up, and here’s why: they’re naturally high in water content and sugar. When roasted, the sugars caramelize, which adds amazing flavor, but too much moisture prevents that coveted crunch.

For crispy sweet potatoes:

  1. Slice them thinly and evenly.
  2. Roast them in a single layer without overcrowding the pan.
  3. Use high heat (around 425°F/220°C).
  4. Toss with a small amount of cornstarch for an extra-crispy coating.

Is sweet potato better roasted or boiled?

Roasting and boiling sweet potatoes both have their perks, but the choice depends on your recipe:

  • Roasting brings out their natural sweetness and creates a caramelized, crispy exterior. Perfect for candied sweet potatoes, fries, or any dish where flavor is the star.
  • Boiling is quicker and keeps the texture soft, making it ideal for mashed sweet potatoes or soups. However, it can dilute flavor and nutrients, as some vitamins are lost in the water.

For most recipes, roasting wins hands-down for flavor and versatility.

What’s the difference between Yams and Sweet Potatoes?

This is one of the most common food myths out there! Despite their frequent mix-up, yams and sweet potatoes are completely different:

  • Yams: These are dry, starchy root vegetables with thick, bark-like skin. They’re commonly used in African, Caribbean, and Asian cuisines.
  • Sweet Potatoes: Smooth-skinned with a moist, naturally sweet interior, these are what most Americans call “yams” at the store.

Health Benefits of Keto Candied Sweet Potatoes

This dish is a keto-friendly powerhouse of flavor and nutrition. By swapping traditional sweet potatoes for low-glycemic butternut squash or rutabaga, you’ll enjoy a dish that’s:

  • Low in Net Carbs: Butternut squash and rutabaga have significantly fewer carbs than sweet potatoes, making them ideal for keto dieters.
  • Sugar-Free: Using a keto brown sugar substitute eliminates the need for high-carb sweeteners, helping you stay in ketosis.
  • Gluten-Free: A naturally gluten-free dish that’s safe for those with celiac or gluten sensitivities.

Description

Enjoy this delicious Keto Candied Sweet Potatoes recipe, a low-carb, sugar-free twist on the classic holiday favorite that’s gluten-free and keto-friendly.

Ingredients
  • 4 pounds Butternut Squash or Rutabaga (, peeled and cubed)
  • 3/4 cup Keto-Friendly Marshmallows (such as ChocZero or Max Mallow)
  • 1 cup Unsalted Butter
  • 1 cup Keto Brown Sugar Substitute (e.g., Swerve Brown or Allulose Brown)
  • 1 tsp Cinnamon
  • 1/2 tsp Ground Nutmeg
  • 1/2 tsp Vanilla Extract (optional, for added depth)
  • Pinch of Sea Salt
  • 1 cup Pecans or Walnuts (optional, for added crunch)
Instructions
    Preheat & Prep:
  1. Preheat your oven to 400°F (200°C). Grease a 9x13-inch baking dish.
    2. Roast the Veggies:
  2. Place the cubed butternut squash or rutabaga on a baking sheet, drizzle with olive oil, and sprinkle with a pinch of salt. Roast for 20–25 minutes, or until fork-tender. Set aside.
    3. Make the "Candy" Sauce:
  3. In a large saucepan over medium heat, combine butter, keto brown sugar substitute, cinnamon, nutmeg, and a pinch of salt. Stir occasionally until the sweetener dissolves and the mixture begins to bubble. Add the vanilla extract if using.
  4. Pro Tip: If you like it extra creamy, whisk in 2–3 tbsp of heavy cream.
    5. Combine:
  5. Remove the roasted veggies from the oven and transfer them to the saucepan. Stir gently to coat, mashing about half for a creamy texture while leaving the other half chunky. Fold in the pecans or walnuts if desired.
    6. Bake:
  6. Pour the mixture into the greased baking dish. Top with keto marshmallows.
    7. Finish in the Oven:
  7. Bake in the oven for 10 minutes, or until the marshmallows are soft and golden.
  8. Optional: If using a broiler-safe dish, broil on high for an additional minute to toast the marshmallows, but watch closely to prevent burning.
