Purple Sweet Potatoes with Praline Topping

Purple sweet potatoes – who knew?! I thought it would be fun to use them in my version of my friend Jan’s sweet potato casserole with praline topping. Of course, “regular” sweet potatoes or yams work well here.

Jan’s recipe was adapted from one she found in Cooking Light over fifteen years ago. I put my spin on her recipe, adding more pecans and spice to the topping. The original recipe called for one egg white, but I threw in a whole egg, added a bit more butter and then some cream instead of the evaporated milk. The folks at CL probably would not approve…

Many thanks to Frieda’s Produce for sending me a generous bag of these purple beauties. Although the potatoes were provided at no cost to me, I received no compensation for this post.

TIP: This entire dish can be assembled a day ahead of serving, an ideal Thanksgiving “side”. Refrigerate overnight, then allow the casserole to come to room temperature – an hour or so – before baking.

    Wow what a color! I’m so impressed that the sweet potatoes retained their color after cooking, I’ve used purple carrots, cauliflower, sprouts, beans and potatoes before and all disappointingly turned a shade of green after cooking!

    • Liz November 23, 2013 at 8:36 am #

      To tell the truth, I’m not sure that the bright purple is that appealing to me when I think of eating the dish…

    Those are the most vivid purple yams I have ever seen, how beautiful and delicious, I love the praline topping and I think adding the whole egg, butter and cream will make it even better, I’m sure it’s great the other way also but it’s the holidays where we can enjoy a little excess. Just beautiful!

    • Liz November 23, 2013 at 1:51 pm #

      Thanks, Suzanne – Happy Turkey Day-

    I just discovered purple sweet potatoes. Their color is fantastic!

    • Liz November 23, 2013 at 1:52 pm #

      Yes, it blew me away when I started peeling them for my dish.

        Eat these all the time out in Hawaii, they are incredibly tasty and healthy. A superfood really, you could literally live off of them. The purple color is the same antioxidant that is found in blueberries.

        Ive been making this dish for a few years now. For a tropical twist, use coconut cream or milk in lieu of the dairy. Adds just a hint of coconutty richness.

    I’ve only had sweet potatoes when in Hawaii, never knew you could get them State-side….so pretty, AND tasty!

    • Liz November 29, 2013 at 10:18 am #

      The color is pretty wild but I liked the flavor, Steve.

  6. Adri November 30, 2013 at 7:12 am #

    Beautiful! I bet this is wonderful.

    These are gorgeous! I’ve seen them but haven’t bought them , so thanks for this great recipe for them. i can’t do the nuts, but pine nuts should work fine i would think!

    • Liz December 1, 2013 at 9:09 am #

      Sure, pine nuts would be delicious here.

  8. SallyBR December 6, 2013 at 7:39 am #

    Beautiful! The color of those potatoes is so amazing, I don’t buy them often enough, and love this idea of using them in a puree type dish

    lovely!

    • Liz December 6, 2013 at 8:24 am #

      Thanks – the color is super intense, even after cooking the dish –

  9. Angel Mamma Bear January 19, 2014 at 5:10 am #

    Wish they sold them year round. They are hard to find. I love the flavor n color.

  10. Lynda November 24, 2014 at 2:02 pm #

    The color of the potatoes is stunning. I love their flavor too. This is a beautiful and festive dish perfect for the holiday table.

    • Liz November 24, 2014 at 3:29 pm #

      Thanks, Lynda, the color certainly is startling, isn’t it?

  11. Dorothy at Shockingly Delicious November 24, 2014 at 4:41 pm #

    Wow, the color! I have some of those on the counter and I thought of something like this, but I am like you…not sure about wanting to eat them. I sure want to look at them, though!

    • Liz November 24, 2014 at 5:47 pm #

      Agree with you, Dorothy – happy Thanksgiving!

  12. suzanne November 24, 2014 at 5:05 pm #

    Wow, what amazing color, I’ve never had purple sweet potatoes before. I love how they look, and the praline topping sounds amazing. Happy Thanksgiving Liz!

    • Liz November 24, 2014 at 5:48 pm #

      Of course, Suzanne, the topping is the best part – Happy Thanksgiving.

    I’m all about the praline topping! I’ve tried the purple fingerlings, but not the purple sweet potatoes – they are definitely a vivid purple, but I know my family would prefer the traditional orange 🙂 I’ll have to try them in some other dish. Happy Thanksgiving to you and Larry, Liz!

    • Liz November 24, 2014 at 6:43 pm #

      Happy Thanksgiving, Priscilla – I’m wondering if you are celebrating in New England with your family or back home. Yep, orange will be on my table – but the praline topping rocks.

  14. Sippitysup November 24, 2014 at 7:27 pm #

    …and they stay purple! GREG

    • Liz November 24, 2014 at 7:59 pm #

      Indeed they do…

  15. Wendy Read November 25, 2014 at 5:39 am #

    The color is fabulous Liz, this recipe is another keeper, I love your choices of ingredients. I am wishing you a wonderful happy and healthy Thanksgiving!

    • Liz November 25, 2014 at 8:04 am #

      Best wishes for a happy Thanksgiving to you and your family, Wendy – thanks, as always, for your support.

    Looks like a very colorful Thanksgiving! What a beautiful color, I’ll look for these at the farmer’s market on Saturday.
