I prefer one-dish meals over the traditional “main and two sides” structure these days because I like to save time and effort. BUT sometimes you just really need a side dish, and when I do, I try to keep them as simple as possible. Not only do I want to save effort, but I really don’t want to upstage my main dish. That’s why simple recipes like these Chili Roasted Sweet Potatoes are so great. They’re easy and serve their purpose. Nothing more, nothing less. :)

How to Season Roasted Sweet Potatoes

I used a mild chili powder blend to season the sweet potatoes, plus just a little salt. That’s all they need–really! The natural subtle sweetness of the sweet potatoes perfectly balances the mild, earthy flavor of the chili powder and a pinch of salt always helps the flavor pop.

What Kind of Chili Powder is Best?

I use McCormick’s chili powder, which has no heat and very little salt. If you’re using a different brand, make sure to check the ingredients and adjust the salt if needed and/or be prepared for a some heat. Some brands of chili powder are spicy, some aren’t. Spicy chili powder goes just as well with sweet potatoes as mild, so either can be used.

What to Serve with Roasted Sweet Potatoes

I made these Chili Roasted Sweet Potatoes to go along side my Cumin Lime Chicken Drumsticks. They cooked in the oven at the same times as the chicken so everything was done at one time, and the offered the perfect complimentary colors and flavors. Everything just went together so very well.

Cook 45 minutes
Total 55 minutes


  • 2 lbs. sweet potatoes ($2.08)
  • 1 Tbsp chili powder* ($0.30)
  • 2 Tbsp olive oil ($0.24)
  • 1/4 tsp salt (or to taste) ($0.02)


  • Preheat the oven to 400ºF. Line a baking sheet with aluminum foil.
  • Wash and peel the sweet potatoes, then cut them into 1/2 inch cubes. Place the cubed sweet potatoes into a large bowl and drizzle with the olive oil, chili powder, and salt. Toss the potatoes until evenly coated in oil and spices.
  • Spread the seasoned sweet potatoes out over the prepared baking sheet so they are in a single layer. Roast the potatoes in the preheated oven for 45 minutes, stirring once half way through. After 45 minutes, the sweet potatoes should be soft and slightly browned on the edges. Total cooking time will ultimately depend on the size of your cubes.

How to Roast Sweet Potatoes – Step by Step Photos

Sweet Potatoes whole on a wooden cutting board

Wash and peel two sweet potatoes (about 2 lbs. total). Preheat the oven to 400ºF and line a baking sheet with foil.

Peeled and cubed sweet potatoes on a wooden cutting board

Cut the sweet potatoes into 1/2-inch cubes. The easiest way to do this is to first cut the potatoes into 1/2-inch thick slices, then cut the slices crosswise into cubes.

Chili Powder bottle

Place the cubed potatoes in a large bowl and add 2 Tbsp olive oil, 1 Tbsp chili powder, and 1/4 tsp salt. I use McCormick’s chili powder, which is mild and contains very little salt. Every brand is different, though, so be aware that if yours contains cayenne or another spicy chili, you could end up with some spicy sweet potatoes. Likewise, if your chili powder contains more salt, you may need to reduce or eliminate the salt I have listed in the ingredients.

Toss the sweet potatoes until they are coated in the oil and spices.

Roast the sweet potatoes in the preheated oven for 45 minutes, stirring once about half way through. When finished, they’ll be soft and slightly browned on the edges. Taste and adjust the salt if needed.

I added a little fresh cilantro to my Chili Roasted Sweet Potatoes just for color in the photos and because I had it on hand from the Cilantro Lime Chicken. It’s totally not needed to make these sweet potatoes mouth-wateringly good, though!

  1. I served these with the green chile enchiladas to get some extra veggies. I really appreciate all the vegetable recipes you have!

  2. This is in my regular rotation. It’s absolutely one of my favorite things to make and eat. I follow the recipe exactly except that I cook them in the air fryer for 15 minutes, shaking the basket a couple of times. So simple, but looks and tastes so fancy. Thank you for sharing the recipe!

  3. Just made these tonight! Discovered at the last minute that I have no chili powder in the house (like, how is that even POSSIBLE??) so I used some Sriracha Lime seasoning blend I had in the cupboard. TO DIE FOR. These were so quick and easy to prep, and so delicious. The kids have asked me to make them again soon.

  4. Thank you Beth. My elderly parents have become picky. I can make this dish for both them and myself, adding some meaty dish for them and some hummus for me. I am so making this recipe this weekend to try it out and tweak it in anyway for their palate.
    Thank you for some more vegetarian dishes.

  5. I had this with the oven-baked fajitas because I didn’t have anything on hand for a side but sweet potatoes. Turned out great! I also used McCormick brand and it wasn’t too spicy. I did have to add a little salt. Great side dish!

  6. Made this last night – amazingly quick, easy, and delicious…but beware if your chili powder is spicy. I had more potato and with the 1 Tbsp of Chili powder, it was overpoweringly hot.

    Next time, I will be sure to avoid using the full amount that is called for in your recipes.

    Looking forward to making this again in the future.

    1. I think it depends on the brand of chili powder you use. I use McCormick, which has no heat to it, but I’ve bought other brands before that did have some cayenne in them, so they were a bit spicy.

  7. “I made these Chili Roasted Sweet Potatoes to go along side my Cumin Lime Chicken Drumsticks. They cooked in the oven at the same times as the chicken so everything was done at one time, and the offered the perfect complimentary colors and flavors.”

    Did you mean Cilantro Lime chicken Drumsticks?

  8. Just tried this tonight with fish and mixed salad and a nice bottle of Chardonnay. The recipe was very easy to prepare and cook. Result was a delicious tasty meal.

  9. This is a great recipe, but I found that powdered ginger added to the mix resulted in a very interesting flavor. Going to make them again tonight.

    1. Any recipe anywhere that I come across, especially when it comes to roasted vegetables, I make sure to check the oven constantly. There are so many factors that can effect the time it takes for the food to be done. Variance in oven temperature, variance in size of the vegetables cut up. Use common sense.
      Love the kick of heat in these!

  10. This was my first time making sweet potatoes and I LOVED THEM! One change, when I first tried my sweet potatoes I felt they were dry and lacking sweetness, so I juiced a lime on top and it made a world of difference. Anyone trying this recipe, if you have a lime on hand, definitely add it at the end! Thanks again Beth for another keeper :)

  11. Tried the whole recipe, the chicken, the rice and the potatoes, followed all your instructions. This was AMAZING and EASY!!!!!!!! Thank you so much! Perfect Saturday food with fresh market produce, easy to trow together, not much clean up! Thank you!

  12. I’m going to give these a try. I love the simple roasted sides. I often make enough for a few servings and eat them cold. Anything roasted tastes good cold, I find.
