This Butternut Squash Mac and Cheese recipe is full of hidden veggie power, but it’s so creamy, cheesy, and delicious, nobody would ever guess it’s healthy! And the best part – it comes together so fast thanks to the Instant Pot! This post contains affiliate links for products I’m obsessed with.
You guys know I am not above hiding veggies in my families meals. I mean, at this point they kind of know it, too.
And for a long time, cauliflower was my hidden veggie go-to. And it still is, but I have added another favorite to the mix:
Butternut Squash.
Just like cauliflower, Butternut Squash ups the creaminess factor in healthy recipes without a lot of fat, but the flavor is mild enough that it is easily hidden (if that’s your goal)…maybe even more hidden than cauliflower.
Butternut Squash has a ton of health benefits, too – it’s high in fiber, has no fat or cholesterol, and has a ton of vitamin A, a powerful antioxidant. And this Butternut Squash Mac and Cheese has a heaping three cups of squash added in!
I use this technique with my Instant Pot Chicken Curry and Rice – the butternut squash adds lots of creamy and just a slight bit of sweetness to that dish, but you mainly taste the yummy ginger and curry.
Ingredients for Butternut Squash Mac and Cheese
You don’t need a lot of ingredients to make this delicious side dish!
- Gluten Free Rotini or Penne Pasta – I tested this with elbow noodles and I felt that the finished texture heavily depended on the brand, but the rotini and penne both came out perfect without regard to brand. Also, if you are not gluten free, you can sub whole wheat pasta.
- Low sodium chicken broth or water – I love the extra flavor that broth gives to mac and cheese, but you can definitely just use water or even veggie broth to keep this dish vegetarian.
- Dry mustard – I always use dry mustard in my mac and cheese bc my momma always did.
- Garlic powder – you can sub fresh garlic if you don’t have the powder, but this is quick and easy.
- Salt – if you use water instead of broth, you might need some extra salt.
- Butter – we use vegan butter for this, but you can use whatever butter you have on hand.
- Frozen butternut squash (1 10oz frozen bag) – I love the time saver of using frozen butternut squash that is already pre-cubed, but you can certainly use fresh squash if you have some.
- Freshly shredded sharp cheddar cheese, packed in tight – bagged cheddar will also work, but for the meltiest cheese, fresh is best.
- Pecorino Romano or parmesan cheese – you can swap this out for extra cheddar, but I love the extra zip the Pecorino Romano gives to mac and cheese.
- Optional – Gluten free breadcrumbs (note – you can make these easily by putting a slice of bread in your blender) – as an optional last step, I love to add some breadcrumbs and cheese for a fun, crispy topping.
How to Make Butternut Squash Mac and Cheese in the Instant Pot
I love making pasta dishes like Mac and Cheese in the Instant Pot because it’s seriously so quick and easy.
Step One: Add pasta and seasonings to your Instant Pot. Then add in your broth, but don’t stir.
Step Two: Add butter and butternut squash to the pot, again, don’t stir. Just layer then on top of the pasta.
Step Three: Cook for 2 minutes on high pressure, then do a quick release when cook time is finished.
Step Four: Stir up the pasta and butternut squash, then add in the cheddar cheese!
Step Five: continue to stir that creamy, cheesy goodness, adding in a splash of broth, if the cheese mixture is too thick.
Optional Step Six: Top with gluten free breadcrumb and some extra cheese. Bake in the oven for ten minutes or until breadcrumbs are crispy!
What if my Pasta isn’t cooked all the way after the two minutes?
If your pasta doesn’t feel cooked all the way or evenly after cook time, don’t panic! Stir it all up and then just lay the lid on the pot. In a couple of minutes, the heat from the pot should finish your pasta! You can also put it on saute to help this!

How can you make this if you don’t have an Insrant Pot?
Nancylynn says
Stay tuned for oven directions, coming soon!
Marisol says
Have you shared non instapot recipe? I would love to make this today!
Nancylynn says
Stove top directions are now added!
Amy says
I don’t have an instant pot. Can this also be made in a slow cooker or Ninja?
Nancylynn says
It’s perfect for a Ninja Foodi! Instead of transferring to a baking dish, just add the breadcrumbs and cheese for the top and broil in your Foodi until breadcrumbs are crispy (about 5 minutes). Enjoy!
Laura says
How would you do this with chicken? Would you add the chicken with the pasta or does it have to be cooked before adding it?
Nancylynn says
I would dice it up smaller, saute it in the pot first for a few minutes and then add in the remaining ingredients and follow the directions accordingly!
Angelique Friedman says
Sounds amazing! What if I only have fresh butternut squash?
Nancylynn says
If you dice it really small, the fresh should work! OR you can precook the squash in the microwave for about 5 minutes (after stabbing all over with a knife or fork) then add to the IP and follow directions from there.
Gina says
If I’m not using frozen squash, so I reduce cooking time?
Nancylynn says
Hi! No – just be sure your squash is diced up very small and keep the time the same!
Jessi says
Sooo good! The first time I tried it, I used gluten free noodles from Aldi. Our pressure cooker isn’t instant pot brand so sometimes it needs a few minutes over the time listed… that turned these noodles into moosh. We still ate it though. The second time I used whole wheat and it came our perfect.

Finally decided to pull out my IP and learn to use it. Soooo glad I did….this mac & cheese is amazing! Thank you so much for sharing!

Nancylynn says
So glad you did too! Keep trying new things in that IP!
Marisol says
Is there a stove top recipe, I don’t have an instapot. Thanks
Nancylynn says
Stove top directions are now added! 🙂
Melissa Allaband says
Any adjustments required if we use non-gluten-free pasta?
Nancylynn says
You should be ok keeping everything the same. But if the pasta is too al dente after cook time, pop the lid back on for a few minutes and let the heat steam the pasta a little bit.
