Sweet Potato Mac and Cheese! Cheesy, vegan cheese sauce tossed with elbows. Made healthy by using pureed sweet potatoes!

Show me someone who doesn’t love Mac & Cheese and I will show you a liar. Kids, vegans, omnivores, picky eaters, everyone loves creamy pasta and cheese. Current company included. If I could eat any food, regardless of calories or fat, it would most definitely be mac & cheese (followed closely by pizza if anyone’s asking).

This similar love was evidenced to me a few weeks back at my girlfriend’s rehearsal dinner where we were treated to a delicious buffet of gourmet food & fresh salads. After the first go around, I noticed that our entire table had gone back for a second plate of a single item: Mac & Cheese. That’s right folks, a table full of presumably adults rushing to get that second helping of cheesy macaroni. Sigh, it’s so, so good.

I was recently gifted a large box filled with California Sweetpotatoes. Mine to create whatever recipes I’d like, sharing with all of you the nutritious tuber that is the sweetpotato. At first glance, I wasn’t sure what I was going to make with them.

Don’t get me wrong, I love sweetpotatoes, but I usually just enjoy them baked, lightly mashed, or roasted– not exactly groundbreaking recipe material. After roasting about 1/2 the box to snack on as I contemplated recipe ideas, the memory of that Mac & Cheese came rushing back to me. Suddenly, that’s all I wanted.

The beauty of this recipe is that is has 1/2 the calories and fat of regular mac & cheese, yet taste just as decedent and creamy. Pureed California sweetpotatoes create a silky, smooth sauce perfect for tossing with hot pasta. I used the O’Henry variety for this recipe, a pale potato with a slightly sweet, creamy taste that is also perfect in soups and stews.

Dare I say this Mac & Cheese is actually good for you? Swapping sweetpotatoes for cheese packs a nutrient punch. California sweetpotatoes provide a “nutrition bang for the calorie buck” with 4 grams of fiber, 2 grams of protein, vitamin C and more than a day’s worth of vitamin A, all for 105 calories per serving (about 1 medium size cooked sweetpotato).

    I’m with ya on the mac & cheese (and the pizza for that matter!) I often roast and puree butternut squash for my mac & cheese but never have done it with sweetpotatoes. Will probably make this recipe this week (if not in the next few days!)

    • DK

      I hope you do! I’ve made it a few times this week, I can’t stop! I’m a mac & cheese monster :)

    Sweetpotatoes and Mac & Cheese. Two foods I love! Always love making healthier mac and cheese dishes!

  • http://Website DianeZ

    Looks good. I will give it a try!
    I assume you are peeling the sweet potatoes at some point (either before or after cooking)?

    • DK

      Yes! Thanks for the correction, updating now- I did peel the sweet potatoes before I boiled them. Thanks Diane, Alex

    When you said at the top of the post that even vegans would like Mac and Cheese, I thought, really? But now that I read your recipe, I am convinced of it! Love this idea!

    • DK

      Vegans still LOVE mac and cheese :) This one is sneaky- it taste rich and creamy but is almost fat-free. Just 1 tbsp. of butter in the whole recipe!

  • Elizabetheats

  • Joanne

    • DK

      Agreed! I hope to be 85 one day and still eating mac and cheese :)

  • Serena

    I just bought some nutritional yeast and haven’t been sure what to do with it. Now I know! Can’t wait to make this!

    • DK

      Glad you bought some! It’s awesome in just about everything, I love sprinkling it on roasted vegetables and popcorn!
