How to roast sweet potatoes (basic method)

You don’t even need a recipe for making roasted sweet potatoes! Make this recipe once exactly as written, just to get a feel for the amounts of flavoring. Then you can go free form: and it’s easy to memorize too! Here are the basic steps, then a little more detail in the sections below (or go right to the recipe):

  • Preheat the oven to 450 degrees Fahrenheit.
  • Dice the sweet potatoes into 3/4-inch chunks.
  • Season with olive oil, salt and garlic powder (see below).
  • Roast about 25 minutes, until tender. No need to stir!

Why to dice into 3/4-inch chunks

This sounds oddly specific, right? But we’ve found that a 3/4-inch dice is the best size for roasted sweet potatoes. A 1/2-inch piece gets small and shriveled, and doesn’t feel like substantial enough bites. 1-inch pieces are rather large and take longer to roast. So 3/4-inch is perfect! (Trust us.)

The flavor secret: garlic powder!

Here’s our flavor secret for roasted sweet potatoes: garlic powder takes sweet potatoes over the top! It doesn’t even taste garlicky: it’s just savory, roasty goodness. To the mix you’ll also add olive oil and kosher salt. The quantities are easy to memorize:

  • 2 pounds of sweet potatoes (about 4 medium)
  • 2 tablespoons olive oil
  • 1 teaspoon each kosher salt and garlic powder

Why to roast sweet potatoes at high heat

The best temperature for roasting vegetables? High heat: 450 degrees Fahrenheit or 230 degrees Celsius. Why? This gets them perfectly tender on the inside and caramelized on the outside. Use a lower temperature and it gets cooked through, but not caramelized.

Throw those sweet potatoes onto a parchment paper lined baking sheet, and roast away! The best part? You don’t even need to stir: just leave the potatoes as is to make them beautifully caramelized on the bottom. Remove from the oven and enjoy!

    1. Great question! Make up to 3 days in advance and reheat in a 350 degree oven (or microwave or on the stovetop). We’ve added a note to the recipe!

  1. Can I leave the potatoes (in water) overnight at room temperature? When I come home from church, is it okay to paper towel and then proceed baking.


  2. Coming from a huge sweet potato lover, this is BY FAR the best sweet potato recipe I’ve ever found. I refuse to cook them any other way! So easy and delicious and it’s always a hit with my guests. So grateful for your recipe! Thank you!

  3. Excellent! I’ll do one potato at a time in the toaster oven to accompany my protein…!

  4. These are great! So simple and easy to cook. I doubled the ingredients to have extra leftovers – it came out perfectly. Thank you!

  5. These are so good! I love sweet potatoes in all their forms but was kind of skeptical with the addition of garlic powder, but it was really good! These will be on rotation at our house for sure now! On a side note – I put the leftovers into my salsa verde chicken burritos (which also included your instant pot Spanish Rice) and it was delicious! :)
