This instant pot creamy sweet potato pasta is a delicious fall dinner! Ready in 30 minutes, and full of delicious flavor and kids will love it. Make this your new instant pot recipe of the week!

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!

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!

I hope you’ll try this easy and delicious recipe.

It’s a winner for me when I can make a dinner that both the adults and the kids will eat.

Ingredients

• 3 tablespoons olive oil

3. 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.

5. Add in the penne, sage, thyme, vegetable broth, and water
6. Stir well, and make sure the penne is well submerged in the liquid
7. Seal the instant pot, and turn to manual, setting the timer for 5 minutes
8. Once the instant pot comes to pressure, it will count down the five minutes. 
9. Once the five minutes is up, do a quick release
10. After the pin drops, safely remove the lid
11. Stir in the heavy cream and parmesan
12. Let sit a few minutes, stirring, and it will continue to thicken
13. Add in the chopped spinach until wilted, then salt and pepper to taste
14. Serve topped with additional freshly grated parmesan cheese
15. Enjoy!

Notes

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