Why This Recipe Works
The genius of this recipe lies in cooking everything together in one pot. The pasta absorbs the flavors from the sausage and sauce while cooking, creating layers of taste that traditional boil-and-drain methods can’t achieve. Pre-browning, the sausage develops deep, caramelized flavors that enhance the entire dish, while the pressure cooking ensures perfectly tender pasta every time.
Why You’ll Love This Recipe for Spaghetti in the Instant Pot
From start to finish, this entire Instant Pot spaghetti recipe takes less than half an hour to get dinner on the table. In addition, it’s customizable with the sauce of your choice, and you can swap out other pasta shapes without altering the cooking time.
And when cooking on a budget, it’s an affordable option that will feed the whole family or provide plenty of leftovers for future meals.
Ingredients You’ll Need
Just a few simple but flavorful ingredients are needed to make a tasty batch of Instant Pot spaghetti and sausage:
- Spaghetti noodles – Classic pasta shape that holds sauce beautifully
- Italian sausage links – Choose sweet or hot based on your heat preference
- Pasta sauce – Quality jarred marinara or your favorite variety
- Olive oil – For browning the sausage and preventing sticking
- Water – Used to rinse sauce jars and provide cooking liquid
While this recipe uses traditional marinara sauce or red pasta sauce, feel free to substitute any sauce you have on hand or prefer. These can include vodka sauce, pesto, alfredo, and others. You can also use either sweet or hot Italian sausage, depending on the flavor profile you’re looking for.
How to Make Sausage and Spaghetti in an Instant Pot
The simple process to make this tasty Italian dish follows steps that should be familiar to many Instant Pot users:
- Heat olive oil using the saute setting and add the whole sausage links.
- Cook until about halfway done, then remove from the pot and slice.
- Wipe the pot clean of excess grease, then add the pasta sauce, sliced sausage, and water used to rinse the sauce jars.
- Add the pasta, secure the lid on the pot, and cook on the manual high setting for 8 minutes.
- Quick-release the pressure from the Instant Pot, stir, and serve immediately.
Garnish each serving with a sprinkling of parmesan or other Italian cheeses if you desire.
Recipe Variations
We’ve mentioned the ability to swap out sauces and use different styles of sausage already, but these are just two ways to modify this dish for your taste or needs.
For one, adding a pinch of red pepper flakes to the pot before cooking the mixture can add a delightful heat to the sauce.
And while this recipe calls for sausage, it’s possible to sub in other meats instead, including ground beef, ground chicken, or ground turkey.
Italian Sausage Instant Pot Pasta Troubleshooting
- A good rule of thumb for achieving the best results is two cups of liquid for every four ounces of pasta.
- If you perform the quick release and see a milky liquid spraying out, stop the release and let the Instant Pot depressurize naturally for a few minutes.
- Adding a bit of olive oil before sealing can also help decrease foaming.
What Goes Well with Instant Pot Spaghetti and Sausage
This dish is hearty enough to enjoy, but it also pairs well with many diverse sides.
A fresh, green salad with a tangy Italian vinaigrette can provide a perfect contrast, while garlic bread doubles down on the rich, carby goodness of pasta and Italian flavors. Roasted or steamed vegetables can also be an easy, nutritious side.
Storage & Reheating Instructions
- Freezing: Freeze in airtight containers for up to 3 months. Thaw overnight in the refrigerator before reheating.
- Refrigerator Storage: Store in airtight containers for up to 5 days. Pasta may absorb more sauce while stored.
- Reheating Method: Microwave on medium power for 1-2 minutes, stirring halfway through. Add extra sauce if needed to restore moisture.

I don’t see any recent comments. Quite a while ago I sent a comment about making this recipe and having a burn warning on my Instant Pot Duo. I tried the recipe again. I saw the comment that the recipe was “very plain Jane”.
We have a Instant Pot Duo Nova (6quart)
Ingredients:
2 TBSP olive oil
1/2 # sausage
1 jar (Trader Joes) pasta sauce (24oz)
2 cups water
1/2 pound pasta
I made one other change. I diced one small onion, 2 stalks of celery, and 2 cloves of garlic. I added the vegetables to the sauteed sliced sausage. I followed your cooking time and instructions.
The spaghetti was very good. My wife and I had two big dinners and a lunch from this one cooking. Thanks for this recipe
This is a very plain Jane recipe. Fortunately, I added some onions, garlic, carrots, and a little bit of seasoning and salt. This recipe would’ve been so bland without the modifications, and after it cooked I had to let it simmer because it was soupy. I don’t think I’ll be using this recipe again.
I am really sorry you did not like this recipe.
I’m wondering if adding the carrots altered the cooking time and flavor? I think I read that somewhere about Instant Pot cooking. Although onions can add liquid when sweating I wouldn’t think that would greatly affect the recipe, nor would the garlic. Just wondering…
I’m also finding the brand of spaghetti sauce makes a big difference. There was one I tried because even though it wasn’t the brand I use it was on sale. I won’t bother doing that again!
With pressure cooking, the cooking time begins when the instant pot reaches pressure.
All Aldi store brand stuff other than kroger chrorizo sausage. Crazy how nice the pasta comes out with your instructions (some of my linguine clumped but that was my mistake; it still cooked and came apart with a fork). Thank you very much for the recipe!!!!!!!!!!
It’s okay. I did 2 jars sauce like it said but only 1 jar of water and it still came out very thin and almost soup like. So wasnt overly happy about that.
So good! Easy and yummy!!!
I just finished my 3rd time with this recipe. All 3 times were a success but this last time was different.
I only had one jar (24 oz) of pasta sauce so I thought I’d cut the recipe in half, only I was skeptical to do that with the water. I used 1 1/2 cups instead and the end result was so so. The spaghetti came out very el dente but still very much edible. The next time I’ll use the suggested 2 cups of water. (I only used a 1/2 pound of the pasta.
I did put the IP in keep warm mode for another 10 minutes with the lid on and that fixed the dish.
Otherwise, what a great meal!

My family loved this. I made it with Kroger brand sausage. Yummo!
I am making cut macaroni. Do I need to adjust the cooking/water time so the pasta is cooked properly?
I don’t know what that is. It is regular pasta? Then try the time I suggested.
Question – if I want to use a different pasta such as gemelli – how do I adjust the time?
I would not adjust the time, please keep the weight of the pasta the same. If you are using tiny pasta, you may then want to reduce the cooking time slightly. When I say “tiny pasta” I mean pasta like anci de pepe, orrzo, or something small like that.
My whole family enjoyed this one.
How long do you brown the sausages?
I would brown them about halfway, meaning I wouldn’t cook them all the way through, get them nice and browned on the outside.
I forgot to put it in the crockpot in the morning, so I found this recipe for my Instant Pot. I made it with close to 2lbs of sausage and added 3 extra minutes to the time. It was fabulous!!!!! My husband and 2 boys (5 & 7) absolutely devoured it and all had seconds.
We used Barilla pasta, Ragu sauce, and Primio sweet Italian sausage links.
I found this recipe when I was in need of a last minute dinner after getting home from work using ingredients that I already had in the house. The best part was that it could be prepared in one pot. I had not thought about cooking pasta in the pot with the other ingredients until I saw this. So easy! I will be making this again. It got a thumbs up from my boys too!,
After 10 Minutes, this came up with Burnt on my Instant Pot after approximately 10 minutes, so I cancelled and quick released all the pressure. I opened it and everything was cooked with a small amount of pasta and sausage burnt to the bottom.
Going to try some more water next time.
Instant Pot DUO Plus 8 Qt 9-in-1
Just curious here, how did you place the ingredients in the pot?
What size instant pot I need to make this? I have a 3 quart will this work?
It should work fine as listed.
I did the recipe in my 3 quart exactly as it specified. The pasta was way undercooked.
I personally would remove the skin from the sausage I I don’t care to have to take it out after browning it. Way to messy and more time spent. Just a thought.
Thank you for sharing. I love the skin on the sausage 😉 What’s awesome about cooking? You can modify recipes to your personal preferences. I hope others try your suggestion.
Since I don’t yet have an Instant Pot (it’s on my wish list) I’m thinking I could do this on the stovetop. Never thought about cooking the spaghetti in the sauce. Your thoughts? Would stovetop yield similar results?
I think it could, make sure you use a really large pot. Barilla makes a quick cooking pasta that is made to cook like this, you may want to try it. I don’t know how it will work across all brands of pasta. I am only familiar with the barilla quick cooking kind.
I think this would work ok on the stove top. I don’t know the exact cooking times. Again, it should work just fine.
You could easily do this one the stove top, I would cook everything the same way, it would most likely take about 35 to 40 minutes to cook.
You don’t say how large the Instant Pot is. And, I have a 2 qt electric pressure cooker. Can you recommend how to cut this portion down for me?
I will correct the recipe for my size of cooker. I am so sorry I left that off. If yours is a 2 quart cooker, I would cut everything by 1/3 EXCEPT the cooking time. I really designed the recipe to go with the 2 jars of sauce and 1 pound of sausage, as those are the common sizes of purchasing each one.
I have the 2 quart instant pot. So I don’t think I need to cut anything down on this one.
Thank you for the recipe!
