Ready to learn just how easy it is to make Instant Pot Cheesy Garlic Butter Spaghetti? Then gather up your ingredients and let me show you…..
How to Make Instant Pot Spaghetti
- Pour stock into Instant Pot insert, then add the rest of the ingredients including the best ever Sea Salt Flakes . BUT DO NOT ADD THE CHEESE.
- Close the lid and turn the vent to sealing position. Set the Instant Pot to manual high pressure for 6 mins.
- Cook till done, then allow for a natural pressure release (NPR) of 6 mins before performing a quick release to let out remaining steam.
- Open lid, give it a stir and then serve.
Tips for Making Instant Pot Pasta
- When you first open there will be a bit more liquid, but if you mix and let stand for a bit the liquid will be absorbed.
- And if you like your spaghetti with lots of sauce, add an extra half a cup of stock or cream.
- Double or (even triple) the ingredients in this recipe to feed a crowd without having to adjust the cook time!
- Feel free to sprinkle in even more Parmesan cheese, or add some grated mozzarella for extra cheesy goodness.
Can I Use A Different Kind of Pasta?
No spaghetti on hand? You can swap in the pasta noodles of your choice.
How Long To Cook Pasta in the Instant Pot?
You will get perfectly cooked pasta in the Instant Pot when you set it for 6 mins on manual high pressure. Then allow for a NPR of 6mins before releasing the remaining steam. Chef’s Tip: the cook time remains the same whether you are making 8 ounces, 16 ounces, or 24 ounces of pasta. 
Instant Pot Spaghetti with Sausage
To make Instant Pot spaghetti with sausage, set the Instant Pot to sauté mode, add a bit of oil or no-calorie cooking spray to the bottom of the insert, then add crumbled sausage. Once the sausage is browned, simply follow the rest of this recipe. Delicious!
Instant Pot Spaghetti Carbonara
For delectable carbonara style flavour, add some chopped bacon (like this Crispy Air Fryer Bacon) to your Instant Pot spaghetti before serving.
What is the Correct Instant Pot Pasta Water Ratio?
When cooking Instant Pot pasta, it is important to have the right amount of liquid. You need to make sure there is enough water to allow for the pressure to build, to fully cook the pasta and to make a sauce. I have found that it takes just about 3 cups of liquid to properly cook 8 ounces of Instant Pot pasta.
Recipe Note
A few readers contacted me saying the got the burn notice when they cooked with the cheese in the pot with the pasta. I use the older Instant Pot model to first make this recipe and have not had a problem making this. However, I have amended the recipe so that you add the cheese in after cooking the pasta. Happy eating!!!

my family loved this dish. it was fast and really delicious. thank you for sharing this dish.
Made it yesterday. So easy, quick, and delicious. This recipe is a keeper for sure! Thank you so much!
Plan to make today, but I have a 6qt Instant pot Duo Plus. Will the recipe times remain the same?
I’d like to know how to do this with gluten-free spaghetti. I use rice pasta by Tinkyada. I have hypothyroidism, so I cannot have gluten. Does the amount of time you need at full pressure change when you use rice pasta in the Instant Pot?
Thank you for this delicious recipe! My husband is very picky about his pasta and we both loved this. Thanks for the tip about mixing the pasta and letting it sit a bit. I only used half the butter and it was still delicious.
Hello Bintu, I love your recipes for the IP and have Pinned many of them, I follow your site religiously and get your weekly emails. One question about the IP garlic spaghetti, can you use fresh pasta? I love making my own fresh pasta. If you have done this, do you need to cook it first or can you just add it to the recipe at the beginning?
Thanks Stu
Yup, a guy.
