Have you ever roasted sweet potatoes? If you haven’t, we are hoping we can convince you to because they make the greatest side dish to any meal!

We first tried these roasted sweet potato cubes over a decade ago, inspired by our recipe for Parmesan Potatoes that we’ve always made.

Since then, we have become OBSESSED and whip them up on the regular! They take about 5 minutes to prep and 20 to bake. They are so simple and so delicious, and our go-to side along with our Roasted Brussel Sprouts and Oven Roasted Vegetables.

Why we think you’ll love it:

  • Simple. This easy side dish takes just about 5 minutes to throw together and 20 minutes to bake.
  • Flavor. The combo of sweet and savory potatoes, plus the cheese and seasonings, is out of this world!
  • Adaptable. Change this potato side dish based on the herbs and seasonings used. Make them sweeter or more savory!

    Honestly looks really delicious! I used to make something super similar to this with my husband. The two best ways both me and him lost weight were from this blog’s recipes and following a proven plan. We actually lost a lot of weight following this program we found. Not sure if I am allowed to post links on here but https://bit.ly/2JR1wT5 was the program we used. Hope it helps someone as well.

    I think the butter was a bit unnecessary & unhealthy, but everything else made for a delicious combo. next time i’ll add a little more olive oil and skip the butter. I added fresh parsley after pulling the potatoes out of the oven. loved it!!!
