This instant pot creamy sweet potato pasta is one of my favorite fall dinners!

Penne drowned in a rich parmesan cream sauce, with sweet potatoes and spinach for added veggies.

This recipe is almost exactly the same as my One Pot Sweet Potato and Spinach Pasta which has long been a favorite in our house!

I have adapted the recipe for instant pot lovers and it’s even simpler than the stovetop version!

The instant pot has fast become a favorite of ours for making recipes in a fraction of the time like this instant pot stir fry. Another favorite is this instant pot broccoli recipe. And instant pot creamy noodles are always a hit!

This pasta has a super thick and creamy sauce and so much flavor thanks to one of my favorite pasta additions – freshly grated parmesan cheese.

Buy a block of parmesan at your grocery store and grate it yourself, that is key for this recipe.

If you have never had freshly grated parmesan before, you will be shocked at the difference!

I’m all for grating your own cheese anyway, but parmesan especially is nowhere near as flavorful when bought pre shredded.

It only takes a few minutes to grate it yourself and is well worth the effort.

Don’t skip this step!

How to make instant pot creamy sweet potato pasta

First, you will peel and dice up 1 large sweet potato into chunks.

If you want your sweet potato to stay in chunks, cut it into larger pieces.

For me, I chopped mine into small pieces and it softened to become part of the sauce.

Either way it’s delicious!

You will also need 1 medium onion, diced, and 10 cloves of minced garlic.

Don’t be afraid of the garlic and onion, as they are the base for all things delicious!

Add your sweet potato, garlic, onion, and olive oil to your instant pot.

Turn the instant pot to Saute and cook your veggies for 7 – 10 minutes, until the sweet potato starts to soften.

Stir often to avoid burning.

Once this step is done, turn the instant pot to OFF.

Add your penne, sage, thyme, vegetable broth, and water to the pot and stir well.

Make sure the penne is well immersed in the liquid.

Turn the instant pot to manual, seal, and set the timer for 5 minutes.

Once the pot comes to pressure (this may take a few minutes), it will cook in just 5 minutes!

This allows for al dente pasta, any longer would result in mushy noodles.

Once your pasta has cooked, do a quick release.

After the pin has dropped, safely remove the top.

Stir in your freshly grated parmesan, heavy cream, and stir.

Give it a few minutes to thicken and keep stirring, then salt and pepper to taste!

The longer it sits, the more it will thicken, and the sauce will still be super creamy.

Toss in your spinach until wilted and you’re ready to serve!

I serve mine topped with more parmesan for flavor.

My toddler absolutely gobbled this one up!

If you have picky kids they may love this recipe.

I loved that he was eating sweet potatoes and spinach and didn’t even seem to notice.

The parmesan cream sauce makes it taste like a fancy restaurant pasta!

Instant Pot Creamy Sweet Potato Pasta

By: Joy Shull
Vegetarian instant pot creamy sweet potato pasta in a parmesan cream sauce.
Prep: 5 minutes
Cook: 15 minutes
Additional Time: 10 minutes
Total: 30 minutes
Servings: 6

Ingredients 

  • 3 tablespoons olive oil
  • 1 onion, diced
  • 10 cloves garlic, minced
  • 1 large sweet potato, peeled and diced**
  • 4 cups vegetable broth
  • 1 cup water
  • ¼ teaspoon ground sage
  • ¼ teaspoon thyme
  • 2 ½ cups spinach, roughly chopped
  • ½ cup heavy whipping cream
  • 1 lb penne pasta
  • 1 ½ cups freshly grated parmesan cheese, plus more to top
  • Salt and pepper, to taste

Instructions 

  • Turn your instant pot to Saute and add the oil
  • Add in your diced sweet potato (see notes), onion, and garlic
  • Saute for 7 – 10 minutes, stirring to avoid burning, until sweet potato begins to soften. If you want your sweet potato to stay intact, cook less time. I cooked mine longer so that it would fall apart and become part of the sauce once cooked. 
  • Once veggies have softened, turn your instant pot to OFF
  • Add in the penne, sage, thyme, vegetable broth, and water
  • Stir well, and make sure the penne is well submerged in the liquid
  • Seal the instant pot, and turn to manual, setting the timer for 5 minutes
  • Once the instant pot comes to pressure, it will count down the five minutes. 
  • Once the five minutes is up, do a quick release
  • After the pin drops, safely remove the lid
  • Stir in the heavy cream and parmesan
  • Let sit a few minutes, stirring, and it will continue to thicken
  • Add in the chopped spinach until wilted, then salt and pepper to taste
  • Serve topped with additional freshly grated parmesan cheese

Notes

** For sweet potatoes that stay in chunks, dice into larger pieces, for sweet potatoes that melt into the sauce, dice into small pieces

    1. This is the first meal I ever made in my instant pot and it was AMAZING!! It was a hit with my husband and kids too! It seems like it would be good with mushrooms, when and how do you suggest adding them?

      1. So glad you enjoyed the recipe! I would add mushrooms in when you are cooking the sweet potato so that they can cook off any liquid.
