I realize these Roasted Sweet Potatoes with Feta may be a tough sell with some people who love sugary sweet potato casseroles, but I loved them and so did my nephew/cooking assistant Jake who never used to like sweet potatoes at all. And I’ve been trying out savory sweet potato recipes for a few years now, and somewhere along the way Jake realized he *does* like sweet potatoes when they aren’t topped with brown sugar/and or mini-marshmallows.

I also think that roasting the sweet potatoes is a wonderful trick to bring out their natural sweetness, and roasting them with red onions and then combining them with something salty like Feta cheese gives that wonderful salty-sweet combination that is so appealing.

And although sweet potatoes will never be a low-carb food, adding a generous amount of creamy low-carb Feta will bring down the carbs and if you use portion control this is probably not as high in carbs as you might be thinking!

How to Make Roasted Sweet Potatoes with Feta:

(This is only a summary of the steps for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

  1. Cut up two large sweet potatoes into pieces that are about 1 inch square.
  2. Cut the red onions into pieces that are the same size (or next time I might make them slightly bigger than the sweet potatoes.)
  3. Toss sweet potatoes and onions with 2 tablespoons of olive oil and 1 tablespoon of my seasoning for Spicy Sweet Potato Fries.
  4. Spread the sweet potatoes and onions out on a baking sheet that you’ve sprayed with non-stick spray or misted with olive oil. (Blogger FAIL, I cooked these about 10 minutes before I realized I hadn’t taken a photo.) If they seem crowded at all, use two baking sheets.
  5. Flip them over a few times while they’re cooking; this is how mine looked after about 25 minutes roasting time; this was the second time I turned them.
  6. I roasted mine about 40 minutes total, but depending on your oven and how big the pieces are, you might need a few minutes more or less.
  7. Season with salt and fresh ground black pepper, sprinkle with Feta, and serve hot.

Roasted Sweet Potatoes with Feta would be a great dish for Thanksgiving, but this is a great side dish all winter long for sweet potato fans.


  • 2 large orange-fleshed sweet potatoes, cut in 1 inch cubes, see notes
  • 2 small red onions, cut into pieces just larger than 1 inch
  • 2 T olive oil (or slightly more, enough to coat all the veggies with oil)
  • 1 T seasoning for Spicy Sweet Potato Fries (see link for recipe below)
  • 1/2 cup Feta cheese


  1. Preheat oven to 450F/230C.
  2. Peel sweet potatoes and cut into cubes about 1 inch square.
  3. Peel red onions and cut into pieces slightly over 1 inch square.
  4. Put sweet potatoes and onions into a bowl and toss with 2 tablespoons olive oil (or slightly more if you need it to get all the veggies coated with olive oil.)
  5. Sprinkle 1 tablespoon seasoning for Spicy Sweet Potato Fries over the veggie mixture and toss until all the vegetables are coated with the seasoning mix.
  6. Spray a large baking sheet with non-stick spray or mist with olive oil.
  7. Spread the vegetables out on the baking sheet (use two baking sheets if they’re even slightly crowded.)
  8. Roast about 15 minutes, then flip them over with a turner, roast 15 minutes more, then flip them over again.
  9. Roast 10-20 minutes more, or until the sweet potatoes and onions are both nicely browned and sweet potatoes are soft.  (They don’t get very crisp, but there should be some browning on the edges.)
  10. Total roasting time will be 40-50 minutes, depending on the size of the sweet potatoes, your pan, and the oven.
  11. Season with salt and fresh-ground black pepper as desired, sprinkle with crumbled Feta, and serve hot!


Orange sweet potatoes are sometimes called yams or sweet yams in U.S. grocery stores.
