Spiralizing your sweet potatoes is quick and easy! For more spiralizer recipes, try my Spiralized Winter Veggie Gratin or these Zucchini Noodles with Shrimp.

I’ve been experimenting with my Paderno Spiralizer, last week I spiralized broccoli stems with turned out awesome in this Spiralized Beef and Broccoli dish. This week I decided to spiralize a sweet potato. Normally I simply roast them, but my friend and I brainstormed thinking about what else to do with it and came up with this dish.

Guajillo Pepper Sauce

The sauce is AMAZING, a recipe she got from her Mexican friend made from dried guajillo peppers which are very mild in heat. If you want this spicy, you could add some chipotle en adobo to the sauce as well. If you cant find dried guajillo chili peppers, I suggest using 2 to 3 tbsp chipotle chilis in adobo sauce in it’s place although it will be spicier.

The quickest way to make this is using leftover chicken. I usually have shredded chicken on hand that I make in the slow cooker, you can see that recipe here or boil it 10 minutes on the stove as mentioned in the recipe below:

How to Make Easy Shredded Chicken in Your Slow Cooker

  1. Grab a few skinless breasts, and throw them in your crock pot. 24 oz (about 3) boneless, skinless chicken breasts, trimmed of all fat.
  2. Add enough water or reduced sodium chicken broth so it covers the chicken. You can season your water with salt if you wish. For more flavor you can add a quartered onion, 1 celery rib, and/ or a sprig of fresh parsley.
  3. Set it for 4 hours on HIGH.
  4.  Remove the chicken and shred with 2 forks. Use the shredded chicken in any recipe that calls for it or refrigerate for up to 3 days. Discard the rest. Makes about 18 oz cooked chicken.

  1. So good! I did substitute elk grind for chicken, added a zucchini and carrot for bulk, and ampped up the spice a wee bit. I think this would be great as a dip also.

  2. I made this for the first time. I didn’t have dried chilis, so I used chipotle in adobo (I like spicy food anyway). I also didn’t have corn, so I skipped that. Still a big hit with me and my husband, who used to claim he didn’t like sweet potatoes!

  3. Would this freeze well to be eaten later? Trying to find good healthy recipes to make and freeze before baby comes 🙂 

  4. OMG! This was SO good! I’m trying to sneak in more sweet potato into my diet (fiber, beta carotene…you know), but I’m not crazy about them. The base of this casserole is spiral sliced sweet potato, and even though I was very skeptical, I went full speed ahead and made it as written. (Note: also the first time I made sauce with dried red chile…SO easy with Gina’s instruction) I absolutely LOVED this meal and am very much looking forward to having this for lunch tomorrow. I’ve not made a bad dish yet from any of Gina’s recipes. My husband has loved them all as well. Thank you, Gina♥️

  5. Made this dish tonight. My county on restriction. So I made a few adjustments.  Used Compari tomatoes,  shoshinto peppers , and queso cheese. Also hard TJ’s sliced sweet potatoes ribbons. I also did not put in blender, so I added  8 oz of tomato sauce. Everything else the same. Put the ribbons in bottom of casserole pan. Put the other ingredients together in sauce pan. , and poured on top . Did not pre- cook anything but onion and garlic. Made sure sweet potato ribbon Nd were throughly covered , layered on sliced queso, covered with foil and put in oven for 1 hr. Serious yum!
    Would strongly suggest you either prep everything the day before, or don’t do it on a day you do housework, and laundry !

    I was a little nervous about this one because my husband is not a sweet potato fan. He loved it.

    Going to follow the guidance of another poster and use the leftovers for breakfast with eggs over it. Yummae!

    Saving to make again for the fam.

    Added bonus: bought a spiralizer; can’t wait to try it out on other recipes.

    This recipe looks delicious. Is it possible to convert this recipe to the crock pot or skillet? I have your Insta pot, crockpot, and stovetop conversions. We travel to Mexico for 3-4 months per year and I do not have access to an oven. I use many, many of your recipes while in Mexico.

    Thank you in advance.


  8. I plan on making this tomorrow night, but I will be using fresh Anaheim peppers instead of the Guajillo peppers. What should I do differently? Should I still boil them before putting them in blender? I also plan to use crushed or diced tomatoes instead of fresh. Thanks!

    I would not recommend this dish for dinner. Maybe I did something wrong, but it was way too mushy and not hearty enough to be satisfactory for dinner. On that note, It was absolutely DELICIOUS the next morning for breakfast. I heated it up in the skillet then topped it with two fried eggs. I would definitely make this again and serve at a brunch, but definitely not for dinner.

  10. Got a new casserole baking dish so I looked for a new recipe that I hadn’t tried before. This was absolutely delicious!! Thanks, Gina!

  11. This one has been on my want to make list for awhile and I am glad I did. I had some left over chicken and used it here. This was wonderful. My husband said better then eating out any day and please make again. We
    loved it. Thank You.

  12. Made this tonight for dinner and even my sick-with-a cold hubs loved it. I couldn’t find the dry chili peppers at the store so used chipotle chilis in adobo sauce but only 1 tablespoon since the hubs doesn’t like spicy hot food. I would have used 2 T if just for me.
    One problem: the cheese stuck to the foil so I lost most of it. I added more cheese and put it back in the oven uncovered for 5 mins to brown cheese. Any ideas on how to prevent the cheese sticking to foil problem?
    Thanks, Gina, for another delicious recipe. And the best news: there are leftovers!!

    1. Another hint: instead of using my big blender, I used my Breville stick blender in the little pitcher that came with it to blend up the sauce. Worked great! And, easier to clean………..

    2. Any time you add cheese to a dish and have to cover the pan with foil, spray the foil with cooking spray and then cover. The cheese doesn’t stick.

    This was so delicious and easy to make and I finally used the spirallizer on my food processor. Loved it! Tasted even better the next day for lunch.

  14. Very tasty! I substituted a 7 oz jar of roasted red peppers (without the liquid) since I did not have guajillo chili peppers and I put a very small amount of jalapeno in the blender. The sweet potato taste is uniquely tasty. Mine looked beautiful but there was a lot of watery liquid left in the pan when you scoop out a serving. I suspect it was the fault of my tomatoes . That part wasn’t pretty but it doesn’t take away from the fantastic flavor.

    Made this recipe on Tuesday. I am not typically a fan of the sweet potato, but I thought I would give this a try.. This dish WOWED me! It was the perfect combination of savory and sweet!

    This site has been a fantastic resource for me in my quest to reduce my calorie intake and choose healthier options with amazing flavors!! What a Win! Thank you.

    1. No spiralizer so I shredded the sweet potato and it worked just fine. Everyone even my sweet potato disliking daughter enjoyed it.

  16. I followed the recipe exactly, except kept the seeds from the chile peppers when blended and thought if lacked flavor, which is surprising since it had so many different ingredients. I added some more salt and smoked salsa and it tasted significantly better. I am usually a huge ST supporter but I’m not sure if I’ll make this again.

  17. Make this one often! Use canned tomatoes generally (until the garden produces) and I sub the sweet potato noodles for butternut squash noodles. Very Weight Watcher friendly. Freezes good. It’s even better warmed up as leftovers!

    We forgot to buy tomatoes so we subbed 12oz of crushed tomatoes instead.


    We had already loved this, but the substitution of crushed tomatoes changed the text of the dish into wonderful comfort food. That’s a permanent change for us.

  19. Hi,
    Has anybody tried this with another kind of meat? I’m guessing it would taste good with turkey breast… do you think it would taste good with ground turkey?

    1. update: I went ahead and made it ground tukrey- seasoned the meat with some cumin, paprika and whatever else I had on hand..t turned out great! Will definitely make it again!

    I used chipotle peppers in Adobo sauce and was a bit heavy handed, sauce was very flavorful but just a bit too hot. Did a quick glance around my kitchen for an answer to tame it down a bit and ended up making a sorta mole with some unsweetened cocoa powder, Mexican instant espresso and just a bit of sugar. Turned out Amazing! This definatley will be included in our go-to-list, with either version of the sauce.
