Even though the holidays are long over, our consumption of sweet potatoes doesn’t have to be – nor should it be!
Find out more about the U.S.history of sweet potato consumption and why you should be eating them throughout the year in my post on Curried Sweet Potato Soup with Tarragon.
Now let’s talk Fettuccine Alfredo. A few months ago I published my recipe for the best Fettuccine Alfredo and included some fascinating history about the dish’s origin and its Hollywood connection. Fettuccine is one of the all-time best comfort dishes – it’s simple, filling and absolutely scrumptious.
Here is a delicious twist on this classic dish. It’s packed with flavor and has a beautiful color!
Plus it’s a great way to pack in a super healthy vegetable.
Got picky kids who struggle to eat their veggies? (Most of us raise our hands.) This is the perfect way to camouflage an especially healthy vegetable and your kids won’t even know it! (Nor will the picky adults for that matter.)
Let’s get started!
Peel and dice the sweet potato in roughly 3/4 inch pieces.
Peel the shallots and garlic. Depending on the size of your shallots, either half or quarter them.
Place the sweet potato, garlic and shallots in a large bowl and toss with olive oil.
Spread the vegetables out on a lined cookie sheet, single layer.
Roast at 450 degrees F for about 25 minutes, flipping the veggies over after every 10 minutes or so, until browned.
Place the roasted veggies in a blender with the hot chicken stock and tarragon and puree until smooth.
Add the cream, salt and pepper and puree again.
Place the puree in a medium saucepan over medium-high heat. Once the mixture begins to simmer stir in butter and Parmesan cheese until melted and the sauce is smooth. Add salt and pepper to taste.
Toss the cooked, hot noodles in the sauce, dish them onto plates, sprinkle with some freshly grated Parmesan and garnish with a sprig of tarragon.
Enjoy!

If you're wondering about the liquid to cheese ratio, the pureed sweet potatoes will thicken the sauce.
Oh that’s a great way to get some goodness into my kids. they love pasta – I can’t wait to try it out.
I ABSOLUTELY NEED THIS. I love the cheesy sauce!!
I cannot wait to try this for dinner! Love this!
Roasting veggies is one of my most favorite ways to cook them. The color alone is beautiful, not to mention sweet potatoes are so good!
I love that you healthified alfredo by adding sweet potato!!! GENIUS!
This looks wonderful! I have a ton of sweet potatoes sitting around and I never do anything with them other than make roasted potatoes. I totally need to try this!
What an awesome and delicious idea…I need to try it.
Such a pretty color and what a great way to get more veggies into your family. Still so creamy!
I’ve got sweet potatos out the yang right now!! This is so luscious looking!! Sign me up!
I love sweet potatoes all year round- not just in fall. 😉 And this sauce looks delicious! Love that you roasted all the veggies- I bet the flavor is amazing.
Normally when I make alfredo I feel so full afterwards that I need to be rolled to my couch. I love that this version uses delicious sweet potatoes and just a touch less butter and cream. Delicious!
So when it comes to kids eating sweet potatoes, I am raising both hands… 🙁 I am putting this dish on next week’s cooking list and hope they will eat them, when they don’t see them in chunks (I’ll just say it’s carrots). It looks so creamy and delicious!
What a creative twist on a traditional classic… I can’t wait to try! Thanks for the recipe!
Two of my favorite things combined! Must try!
I’ve made this yesterday, I loved it and the kids ate it not knowing there are sweet potatoes inside until after the meal. 🙂 I used milk instead of cream, cause I didn’t have any.
That’s awesome, Adina! I’m so happy you made and enjoyed this. And I’m especially happy to hear when kids eat a lot of healthy veggies, even without knowing it 😉 Thanks so much for the feedback!
Made this with coconut milk instead of cream (and nutritional yeast instead of parmesan) to make it vegan and it was delicious!
I found it could use a /wee/ bit of a souring agent, but not too much!
Thanks for the tips on veganizing this, Elizabeth, and I’m glad it was a hit!
