How To roast sweet potatoes in the oven

First thing to roasting these sweet potatoes in the oven is getting them prepped. 

  • Peel the potatoes.
  • Cut into 1 inch cubes. 
  • Drizzle with olive oil. Stir to make sure the potatoes are coated in the oil.
  • Sprinkle with salt and seasonings.

How To make roasted sweet potatoes Crispy

  1. Roast them at a high heat. To make the sweet potatoes crisp up we will be roasting them at 425 degrees. Roasting them at a high heat gives that almost caramelized coating to the potato.
  2. Ensure that the sweet potatoes are coated in the olive oil.
  3. And most importantly, stir the sweet potatoes halfway through the bake time to help all the sides get crispy.

How to Season Crispy Roasted Sweet Potatoes:

My personal preference is the recipe shared below. A bit of salt and a spice mixture called Herbs de Provence. It’s a mix of: thyme, marjoram, summer savoy, rosemary, mint, fennel seed, sage and lavender flowers. And it’s basically magical on these roasted sweet potatoes.

Other options for Crispy Roasted Sweet Potatoes:

  • Honey or Maple and Cinnamon (drizzle with olive oil first then the honey or maple syrup and sprinkle with cinnamon and a pinch of salt)
  • Garlic Parmesan– drizzle with olive oil. Sprinkle with garlic powder, grated Parmesan (the dried kind that you would use on pizza) and salt. Top with fresh parsley after baking. 
  • Classic Salt and Pepper.

  1. Made these with some sea salt and garlic. They turned out really good! I used precut sweet potatoes from the store. Made this really easy. Thanks for the recipe.

  2. I have never used herbs de provence! But now I must! Can you just buy the mix in the spice section at the store? I would love to make these sweet potatoes!

    1. Hi Melissa! It’s my new favorite seasoning. I bought it just to recreate these potatoes. And yes, I bought mine in the spice section at Walmart, and I’ve seen it at Trader Joes also. I’m sure it’s at most markets.

  3. Oh these look good and healthier than canned yams or the frozen sweet potato casserole in Aldis even. I will definitely have to try this soon!
