Ingredients & Substitutions

This section explains how to choose the best ingredients for roasting sweet potatoes, what each one does in the recipe, and substitution options. For measurements, see the recipe card below.

Sweet Potatoes:

Some considerations when choosing and preparing sweet potatoes to roast:

  • Variety – Garnet or jewel varieties, with their reddish skin and orange flesh, work best for roasting and you can find them at most grocery stores. You can also substitute yams, which are similar to sweet potatoes, but less sweet.
  • Skin – It’s up to you if you want to peel them or leave the skin on. Keep in mind that the skin is packed with nutrients, including potassium, calcium, vitamin C, and fiber.
  • Chopping – I cut the potatoes into 1-inch chunks, but you can do sweet potato wedges if you prefer.


  • Olive Oil – Helps the potatoes hold onto the seasonings, keeps them from sticking to the baking dish, and allows them caramelize. You can substitute any neutral oil you prefer.
  • Brown Sugar – This is optional, if you like more sweetness. I typically avoid refined sugar, so I use Besti Brown Monk Fruit Allulose Blend instead, but you can also omit altogether. You could also substitute honey or maple syrup if you like.
  • Garlic – Mince fresh garlic cloves for the best flavor. If you are in a hurry, you can use jarred minced garlic instead, or a teaspoon of garlic powder.
  • Cinnamon – Adds a sweet and woody flavor with a slight citrusy note to sweet potato cubes. For even deeper flavor, try swapping it with homemade pumpkin pie spice or savory spices like cumin and paprika.
  • Sea Salt – I recommend sea salt instead of kosher salt for better flavor, but either works. The salt also helps them crisp up.
  • Black Pepper

Optional Toppings:

  • Butter – Gives the potatoes a richer flavor and adds a little moisture to them after roasting.
  • Fresh Herbs – Parsley or thyme add a burst of fresh flavor and aroma to the finished dish.

  1. Prep. Preheat the oven to 425 degrees F. Lightly grease a 9×13 baking dish with olive oil.
  2. Season. Cut and arrange sweet potato cubes in the baking dish. (Don’t crowd the pan too much — ideally no more than 2 layers of cubes.) Drizzle with oil, and add the brown sugar or Besti Brown (if using), minced garlic, cinnamon, salt, and pepper. Stir to coat.

How Long To Roast Sweet Potatoes?

Roasting sweet potatoes in the oven will take about 35-40 minutes.

What Temp To Roast Sweet Potatoes?

The higher the temperature, the sweeter your potato will be. For a sweeter potato, 425 degrees F is the ideal temperature. But, if you want less sweet fork tender, crispy skinned, roasted sweet potatoes, 400 degrees F is the ideal temperature to use.

Tips For The Best Roasted Sweet Potatoes

Tips For The Best Roasted Sweet Potatoes

If you want to make this the best oven roasted sweet potato recipe, follow these tried and true tips:

  • Cut potato cubes to the same size. This ensures that the cubes cook at the same rate.
  • Soak potato cubes if time allows. This step is not required, but it removes excess starch which gives the potato cubes a crispy exterior. To do this, soak the diced potatoes in cold water for at least 30 minutes before cooking, or overnight. Pat them dry before adding oil and seasonings.
  • Don’t crowd the pan too much. Two layers in a 9×13 baking dish is fine as long as you stir halfway through. You can also use a baking sheet instead for even more browning, and in this case stirring is less important if the potatoes are in a single layer.
  • Don’t use parchment paper. This is not necessary for a baking dish anyway, but even if using a sheet pan, leave it unlined or use foil and grease well. Parchment paper will inhibit browning and caramelization.
  • Position the oven rack correctly. Place the oven rack in the center of the oven for even heat distribution.
  • Doubling or tripling the recipe? Use multiple baking dishes so potatoes can cook evenly and become slightly crispy.

Storage Instructions

  • Store: Keep leftovers in the refrigerator up to 5 days.
  • Meal prep: Cut up potato cubes, then keep them submerged in a bowl of water in the fridge. This prevents browning, and will also help make your potatoes crispy when you cook them. Drain and pat dry before roasting.
  • Reheat: Warm this roasted sweet potato recipe in a skillet on high heat, or in the oven at 350 degrees F, to crisp them up. Alternatively, you can put them in the microwave, but they won’t be crispy that way.

Can You Freeze Roasted Sweet Potatoes?

Yes, you can freeze leftover sweet potatoes for up to 3 months. Keep in mind that the potato texture may change.
