Very early tomorrow morning I’m getting on a plane to Chicago, where I’ll be attending BlogHerFood15 (and speaking about Pinterest; are you following me there?) So things might be a little quieter than usual here for a few days, but I did want to share one more updated Thanksgiving favorite before I leave town. I made these Spicy Crockpot Sweet Potatoes with my niece Kara, and we used the new Crock-Pot Casserole Crock Slow Cooker (affiliate link). These sweet potatoes have the same seasoning as Spicy Sweet Potato Fries, the recipe that turned me into a sweet potato fan.

This shape of slow cooker worked beautifully for Spicy Crockpot Sweet Potatoes (and the casserole crock can go in the oven, so we browned the sweet potatoes a little bit when they were done) but any large oval slow cooker will work. And did we ever love this recipe! I butter since it’s a Thanksgiving recipe, and Kara and I both devoured it when we tasted the results. Give this a test run before Thanksgiving and see if you can save oven space by making slow cooker sweet potatoes for the big day.

And if you’re really a sweet potato fan, there’s a whole collection of Slow Cooker Sweet Potato Recipes on Slow Cooker from Scratch, or check out Favorite Healthy Sweet Potato Recipes to see more of my favorite dishes that use sweet potatoes!

This is a holiday sweet potato recipe that anyone can enjoy, even if you’re dieting or restricting sugar for health reasons. If you want a recipe that’s vegan, just omit the optional butter and this will still be delicious. And I strongly suggest doubling or tripling the spice mixture, because you’ll want to be making this recipe or Spicy Sweet Potato Fries over and over once you’ve tried them.

By the way, these orange sweet potatoes are not yams, even though that’s probably what your grocery store is calling them!

  1. Peel about 4 pounds of orange sweet potatoes and cut them into pieces about 1-2 inches square.

  3. Spray your slow cooker with non-stick spray and spread the sweet potatoes out, dotting with a little butter if desired.
  4. Cook on high until the sweet potatoes are soft (about 3 hours) then mash slightly.
  5. You can brown them for 15-20 minutes in a 450F/220C oven if desired, but that’s optional. (Be sure your slow cooker insert can go in the oven.)

Spicy Crockpot Sweet Potatoes

Spicy Crockpot Sweet Potatoes

Yield 8 servings
Prep Time 15 minutes
Cook Time 3 hours 15 minutes
Total Time 3 hours 30 minutes

Make these delicious Spicy Crockpot Sweet Potatoes for a holiday meal, and you'll have more room in the oven!


  • 4 lb. orange-fleshed sweet potatoes (4 large or 5 medium sweet potatoes, often called yams or sweet yams in U.S. stores)
  • 2-3 T olive oil, divided
  • non-stick spray for crockpot
  • 1 T sweet potato spice mix, divided (see below)
  • fresh ground black pepper to taste
  • sea salt to taste (I used a sea salt grinder)
  • 2-3 T butter to add to the top of the sweet potatoes (optional, use more or less to taste)

Sweet Potato Spice Mix:

  • 2 T ground coriander
  • 1 T ground fennel
  • 1 T dried oregano
  • 1 T Aleppo Pepper (or use a smaller amount of cayenne pepper)
  • 2 T kosher salt


  1. Grind the herbs together with a mortar and pestle or spice grinder, then mix in the salt.
  2. Peel sweet potatoes and cut into pieces about 1-2 inch square.
  3. Put sweet potatoes into a large bowl and toss with 1 T olive oil and 1 tsp. spice mix. Add another tablespoon of olive oil and another teaspoon of spice mix and toss again.
  4. Then one more time, add a tablespoon (or less) of olive oil and another teaspoon of spice mix and toss again. (Please don't get lazy and add the olive oil and spice mix all at once or the sweet potatoes won't get evenly coated with the mixture.
  5. Spray inside of slow cooker with non-stick spray or olive oil.
  6. Put sweet potatoes in crockpot, spreading them out in a single layer as much as you can, and dotting with a little butter if desired.  
  7. Cook on high, stirring a couple of times and pouring off any water that accumulates under the lid.
  8. Sweet potatoes are done when they're completely softened and fragrant, about 3 hours.
  9. Mash slightly if desired, and season to taste with fresh ground black pepper and sea salt.
  10. At this point you can brown the sweet potatoes a little in a pre-heated 450F/220C oven for 15-20 minutes. We did think that gave good results, but it's totally optional. (Make sure your slow cooker insert can go in the oven.) 
  11. Serve hot, dotted with a little more butter if desired.
  12. Make Ahead Tips: Sweet potatoes can be cut and mixed with olive oil and seasoning earlier in the day. Cooked sweet potatoes could be kept in the crockpot on low or warm for a few hours if needed.


We made this in the Crock-Pot Casserole Crock Slow Cooker (affiliate link) which was really perfect for this recipe, but any oval-shaped large slow cooker will work.

  1. Do you think this could be doubled? I’m cooking for a lot of people and have a large slow cooker.

  2. Dana, you could definitely cook sweet potatoes in the crockpot with any spices you like the flavor of combined with the sweet potatoes, but this combination is really great. If you have some of these, I’d use the ones you have (especially fennel and coriander.) Spike isn’t similar to the flavor of this at all and I haven’t tried it on sweet potatoes.

    You might try googling “sweet potato fries” and see what other kinds of seasonings people use on them that you have.

  3. Those look great ! I’ll have to give that spice combination a try I love coriander so I bet I would like those.

  4. if you don’t have that exact spice mixture on hand, anything you suggest in a pinch? spike? a mixture of more common dried herbs?

    happy thanksgiving all!

  5. sounds like a great combo of spices, and i have been trying to bust out my crockpot more!!

  6. A friend called today to tell me that she’s been commanded to bring sweet potatoes with marshmallow topping to a Thanksgiving dinner, because the host’s son requested it. When I found out that the son is 25 years old, I laughed — but honestly, I’d rather have my sweet potatoes done like yours, savory and not so sweet.

  7. Where are my manners? This is what happens when I’m at school all day and not feeling that hot. Thanks for the nice comments everyone!

    Heather, I promise I didn’t add any liquid at all. I do think the crockpot should be quite full. I stirred them a few times, or they might have stuck on the bottom.

  8. Ooooh I love sweet potatoes & I love my crockpot! This recipe sounds perfect. And thanks for the advice on not adding too much spice…it was like you were talking directly to me!

  9. So I use my crockpot occasionaly to cook meat. I’m skeptical about the fact that you don’t add liquid. You have me wanting to plug the crock pot in but I only have one sweet potato. I’ll do it tomorrow! They look great and the spice mix sounds great.

  10. Marsha, just make the Spicy Sweet Potato Fries (recipe linked in this post) in your oven. I wouldn’t do it on the stovetop.

  11. Kalyn, could these be done on the stove or in the oven? I’d like to try this tasty sounding recipe, but I no longer have a crockpot.

  12. Kalyn this sounds soo good! I’m hosting a Thanksgiving party for my coworkers this Sunday and one of my charges is sweet potatoes. I’m now debating between making these and a sweet potato mash with sage and caramelized onions that I picked up from Food Blogga.

    So many choices! 🙂

  13. I love sweet potatoes!! Never tried them in the crock pot!

  14. Wow! I am impressed, by both the use of the slow cooker, and your spice mix.

  15. I’m a big fan of using the crockpot on Thanksgiving – one year I bought two bright red crockpots to heat and serve and give me more oven space for an overly large turkey. Great idea to prep sweet potatoes in the crock pot.

  16. Oh that sounds great! I wish I had known about it before our Thanksgiving… but I’ll save it for next year!j

  17. I should start considering a crockpot: it sounds so useful. Interesting spic mix: thanks for the pointer.

  18. There is something special about slow-cooked sweet potatoes… I’ve only ever had them done like this with sweet seasonings. Intrigued by the spicy flavours – thanks for the inspiration!

  19. Very clever! Now I have to buy myself a crock pot!!

  20. And yet there are somethings that more is more but I’ll trust you on this one Kalyn!

    Feeling better I hope!
