Brown butter sweet potato alfredo is a great way to still get the creaminess of the classic alfredo sauce but with a lighter and more flavorful sauce approach. The brown butter gives it a nice, nutty flavor without overpowering the dish.

I finally found a new tv series to get hooked on. Besides my undying love for Friday Night Lights and Scandal (which this whole winter hiatus is not cool right now!), I have fallen in love with Nashville. It’s weird seeing Connie Britton/Tami Taylor as Rayna on Nashville but man, I love that lady (can I please have her hair?). She is always so dazzling.

Nashville. I can’t stop watching it. I wish it were [free] streaming on Amazon Prime or Netflix but it’s not so I’ve been getting the discs in the mail from Netflix which is still great but I’m always left in suspense disc after disc waiting for the next disc to arrive! I’m on disc 2 and there is so much drama! I love it! I also watched the pilot episode of One Tree Hill and I must say, I can see myself getting hooked on that, too.

I need to give Downton Abbey a second shot. I watched the first couple episodes and I just couldn’t get into it. They were so boring and dragged on and on. I know it’s for character and plot development but I couldn’t force myself to sit through it. I really want to, though, because I want to feel the excitement that everyone else is feeling. It is free streaming on Amazon Prime so there’s no reason for me not to watch, right? Oh, and I just added Homeland to my DVD Queue – I hear that show is addicting too.

This pasta was made ages ago. Like 3 months ago. Oops. I’ve held out on you for too long and I hope you enjoy it nonetheless! I think this is a fairly lightened up dish to the alternative alfredo cream sauce considering that the creaminess of this pasta comes from the sweet potato and roux. I decided to amp up the flavor by adding brown butter – you can’t ever go wrong with that and it’s only 2 tablespoons so it’s not like you’re killing your entire days’ worth of calories over this dish – that is, unless, you eat like 7 bowls of this, but we all know you won’t do that, right?

In case you aren’t sure what brown butter really is, it’s really butter that has been browned in a skillet to create a nutty and unbelievable flavor! Just don’t burn it!

**How to brown butter: place butter in a skillet on medium heat. Immediately begin whisking it. It’ll start to foam and within 2-3 minutes, brown bits will start showing up at the bottom. At this point in time, I usually will take the skillet off the heat and start swirling the butter around in the pan in the air so it doesn’t quickly go from brown to burned. Once you see a nice brown color in the butter (and start smelling the amazingness), you’ve achieved brown butter awesomeness!

Brown butter sweet potato alfredo is a great way to still get the creaminess of the classic alfredo sauce but with a lighter and more flavorful sauce approach!

Servings: 4 -6
Ingredients
  • 2 tbsp unsalted butter, browned
  • 1 medium sweet potato cubed into 2-inch cubes
  • 2 tbsp all-purpose flour
  • 1 cup whole milk
  • 1 3/4 cup water, divided
  • 1 cup freshly grated Parmesan cheese
  • 1 pound dried spaghetti pasta, cooked according to the directions on the box
  • 1/4 tsp cayenne pepper, more or less depending on heat preference
  • Salt and pepper to taste
Instructions
  1. Bring a pot of water to a boil and add the cubed sweet potatoes and cook until fork tender. Carefully place sweet potatoes into a blender and puree until smooth.
  2. In a large pot over medium heat, add the brown butter and whisk together with flour for 30 seconds. Turn the heat up to medium-high and carefully add the milk and continue whisking until mixture thickens, about 3-4 minutes. At this time, add the pureed sweet potatoes and 1 1/2 cup of water. Let the mixture simmer for 5-7 minutes until thickened then add the Parmesan cheese, cayenne, salt, pepper, and turn off the heat. If the mixture seems too thick, you can add the remaining 1/4 cup of water to thin it out.
  3. Add the cooked pasta to the pot and toss until well-coated.

    Well, it took me long enough to finally make this, but I had to let you know just how much we loved this! My husband said, “If you weren’t sitting right here, I’d lick my plate!” This is really company good!

    To you think the whole milk could be replaced with a nondairy substitute like almond, coconut or soy milk?

      I’m sure it could, but I don’t know how it’ll react in the sauce (like if it’ll separate/curdle) since I haven’t personally tested/tried it myself. You should definitely try it out though!

    Would a baked sweets potato work? I bake them all the time for my one year old.

      Yes, I can’t see why it wouldn’t work!

    Would it throw off the flavor if you used chicken or vegetable broth in place of the water?

      Nope, it wouldn’t!

    OK… so I had all these sweet potatoes lying around and just needed to do something with them. This inspired me. Thank you. I did change it up as I have a 16 year old in the house that is an endless pit when it comes to eating, so I had to make a huge casserole to last a few days. My stepson loved it! I used all organic ingredients… so here is what I did. I boiled the sweet potatoes – 2 large ones. I sautéed one onion in a stick of butter and added 2 tbsp of brown sugar. While that was simmering, I pureed the sweet potatoes with milk and added a little nutmeg. I then cooked it all together until it thickened up. I poured it over elbow macaroni. For the finale, I browned some small bits of bacon and stirred it in… WOW! Thank you again for helping me feed the teenager!

    Added a bit of garlic powder but followed the recipe as is and man is this good :) I’ve never made a roux type of sauce before either. I topped this wonderful dish with some sliced oven “fried” chicken tenders.

    Might Be a silly question but do you drain the potatoes before pureeing them?

    • Julie

      Yes, drain them before pureeing.

    How do you think this would taste over spaghetti squash?

    Made this tonight and it was very delicious! A couple thoughts to future readers:
    1. I ended up with more sauce than I felt I needed! It’s hard to complain about really saucy pasta lol, but if you’re looking to lighten this up a little bit, you could definitely make like 3/4 of the sauce and still have plenty.
    2. I definitely won’t make this again with angel hair pasta. The sauce was thick and sticky (even after adding even more water than suggested), and the angel hair pasta just ended up in huge clumps. I’d make this with a penne or something like that in the future.
    Very yummy recipe though – I didn’t change a thing when I made it and will definitely be making it again!

    Wowzas! This sounds SOOOO good. Saving this recipe!

    This looks nice!
    I have sweet potato leftovers in my fridge, and was just googling what to do with them. Will try this recipe tonight.

      A salad? Or some delicious crusty bread!

    The spaghetti pictured looks thin, not quite angel hair thin. What kind did you use? I want to try!
    Thank you

    • Julie
      01/30/2016 at 5:44 pm

      I actually did use angel hair! I don’t know why my angel hair looks slightly thicker but that’s definitely what I used! Haha

    I was just looking for something to use with the Roasted Root Vegetable Ravioli I got at Trader Joe’s AND a way to use up some sweet potatoes and here you were! (Thank you Google.) I think I’ll add some toasted, chopped pecans or walnuts for texture and extra taste. Great recipe!

    Made this last night and a few notes:
    If I stuck to the exact recipe it was very bland. Had to add more cayenne, garlic salt, and other spices I had on hand. Also added lots more parm than suggested and added grilled chicken. I loved the idea of using sweet potatoes, but it needed some love to suit my tastes. I hope that helps some people trying to make this! Thanks for the awesome idea using sweet potatoes Julie!

    I was “challenged” by my daughter to make a pasta sauce with sweet potatoes. I made yours and it was delicious!

    I cooked a big batch of pasta and made 3 versions- one without spicing
    one with nutmeg
    one with cayenne pepper as recommended in the recipe.

    My daughter preferred the one with nutmeg.
    I also shortened the prep time by putting the sweet potato in the microwave for 4 minutes.

    I made this tonight. It’s VERY good. It tastes like the richest, cheesiest mac and cheese sauce ever. I will definitely make this again.

    This was an absolutely delicious recipe. So glad I found your site on Pinterest. We had a chicken to ours and it was phenomenal.
