This Vegan Instant Pot Italian Pasta is so incredibly easy and fast to make, requiring only 8 simple ingredients. A 1 pot meal that is oil-free, dairy-free and is topped with a delicious vegan parmesan cheese and fresh basil!
You all already know how much I am all about the simple, but incredibly delicious, easy vegan recipes. That is so important to me. Well, the instant pot just further enhances how easy and quick you can prepare a delicious plant-based meal. This Vegan Instant Pot Italian Pasta is so delicious, full of flavor and extremely fast and easy.
I topped it with black olives, fresh basil and my Vegan Lemon Parmesan Cheese. Totally optional, but just an extra yummy boost of flavor. Plus, the parmesan only takes 5 minutes to make.
I received an instant pot for my birthday last month and have been using it nearly on a daily basis. I’ve been testing many different types of recipes, just getting a feel for it overall. Of course, my love of pasta should come as no surprise that it would be the first type of vegan instant pot recipe I would share.
INGREDIENTS NEEDED
(Only 8 main ingredients needed. Full details and measurements on the recipe card below.)
- Red onion
- Garlic powder
- Italian seasoning: Store-bought or my homemade blend. Just make sure that if you use store-bought, it has no added salt or red pepper flakes.
- Tomato sauce
- Rotini pasta: I used a regular gluten (not whole wheat though) rotini pasta. If you use gluten-free, please research adjusted times for gluten-free pasta in the instant pot.
- Pure maple syrup: Balances out the acidity, you don’t want to leave it out. It really adds dimension to the the flavor.
- Dark balsamic vinegar: Adds depth of flavor to this sauce. This is not the white balsamic, but the dark aged balsamic. I use either the Alessi or Pompeian brands.
- Fresh basil: Using fresh herbs in simple meals like this really do make a difference to the overall flavor, so don’t leave it out!
HOW TO MAKE VEGAN INSTANT POT PASTA
Step 1: Cook the onions on the saute setting until they become tender and caramelized (browned). Add water as needed to prevent sticking and burning.
Add the spices and stir for about 30 seconds to toast them and release their aroma. It will absorb any residual moisture.
Step 2: Add the remaining ingredients, except the basil and optional ingredients. Stir the mixture really, really well so it is mixed thoroughly.
Step 3: Cook on high pressure for 5 minutes and then naturally pressure release for 5 minutes only. Set the timer. Do a manual quick release of any remaining pressure, using a pot cover to protect your hand. Make sure to never stand too close to the pot or near the steam vent.
Step 4: Open the lid and it will look quite soupy, this is normal. Stir the pasta around for 1 minute or 2 and it will absorb the remaining liquid perfectly, making it nice and saucy.
Step 5: Stir in the basil and add to serving bowls. Garnish with sliced olives and my Lemon Parmesan cheese if desired.
FLAVOR
The key to this tomato pasta sauce is the balance of flavors. Tomatoes are very acidic and a bit one note, so to bring that alive, we are using these 3 ingredients that add a touch of sweetness to create a really delicious and balanced tomato sauce:
- Pure maple syrup: Just enough to make the overall sauce balanced and taste so delicious.
- Red onion: We are cooking the red onion until soft and caramelized, to where they are browned and sweet and add delicious flavor.
- Dark balsamic vinegar: This exact vinegar adds a mild sweetness and great punch of balance to the overall flavor. It brings the sauce alive!
NO INSTANT POT?
I specifically created this recipe for instant pot users. But, if you don’t have an instant pot, no worries, I have another amazing tomato and pasta recipe that is similar and full of flavor. Try this Easy Tomato Garlic Pasta instead!

Vegan Instant Pot Italian Pasta
Ingredients
- 1/2 packed cup (80g) finely diced red onion
- 2 tablespoons garlic powder (yes, tablespoons, lots of flavor!)
- 2 tablespoons Italian seasoning (I use my homemade blend, but store-bought is fine, just make sure it is unsalted)
- 1/2 teaspoon fine sea salt and 1/4 teaspoon ground pepper
- 3 cups (720g) tomato sauce (or called passata)
- 3 cups (720g) water
- 1 tablespoon (15g) dark balsamic vinegar (really brings the sauce alive, don't omit) This is not the clear balsamic, but the dark aged balsamic. I use either the Alessi or Pompeian brands.
- 1 1/2 tablespoons (30g) pure maple syrup or agave (really enhances the overall sauce flavor and balances the acidity, so don't omit)
- 4 cups (360g) rotini pasta (please note that if you use GF, the time may change in the IP, I only use wheat)
- 1/2 cup chopped fresh basil
- Optional: sliced black olives
- Optional: My Lemon Parmesan (so good on top and only takes 5 mins)
- I use this scale.
Instructions
- Have all ingredients measured and ready to go, this is a quick meal! Add the onion and a few tablespoons of water to the instant pot and turn to normal saute setting. Cook for 5-8 minutes, stirring often until the onions are tender and caramelize (turn warm brown). Add only tiny amounts of water as needed to keep the onion from sticking/burning. Turn off the saute mode.
- Add the garlic powder, Italian seasoning and salt/pepper and stir around for 30 seconds until fragrant. If it's too dry to stir, add a tiny splash of water. Then add the tomato sauce, water, vinegar, syrup and pasta and stir the mixture really, really well so it is mixed thoroughly.
- Cook on high pressure by selecting either manual or pressure cook and set the time to 5 minutes. Please note that it takes about 10 minutes before the IP will come to pressure and start the 5 minutes cooking. After the 5 minutes is up, allow the instant pot to naturally pressure release for 5 minutes only. Set the timer. You don't want to let it sit longer than that or it can make the pasta mushy. TIP: What I basically like to do is as soon as the instant pot has reached pressure and it begins the 5 minutes cooking, I set a timer for 10 minutes (for the 5 mins cooking and 5 mins to sit). Do a manual quick release of any remaining pressure, using a pot cover to protect your hand. Make sure to never stand too close to the pot or near the steam vent.
- Open the lid and it will look quite soupy, this is normal. Stir the pasta around for 1 minute or 2 and it will absorb the remaining liquid perfectly, making it nice and saucy, as pictured. Turn off the IP.
- Stir in the basil and add to serving bowls. Garnish with sliced olives and my Lemon Parmesan cheese if desired.
Could you please clarify what you mean by dark balsamic vinegar? Do you mean regular balsamic vinegar (as opposed to white balsamic vinegar), or is it a product labeled “dark balsamic” (and is that the same as aged balsamic?)? Thank you so much!
Hi Cari, I just updated the ingredients to be more specific. This is not the clear balsamic, but the dark aged balsamic. I use either the Alessi or Pompeian brands.
Thank you!
Thank you for including the nutritional information. However, im not seeing how may servings this makes. Thanks!
Hi Joy, look towards the top of the recipe card, it is 3-4 servings. 4 small bowls or 3 quite large ones.
Are you talking about regular pasta or whole wheat pasta? Because that is what I always use.
Just regular, not whole wheat. I am prefer regular over whole wheat, but if you use whole wheat pasta, I imagine it would cook the same!
If I use a pound of pasta, would I have to change a lot of the ingredients? All my packages of pasta are 400 grams.
Just measure out 4 cups or weigh 360 grams. A pound is almost 2 cups more and would be way too much for how I’ve written the sauce portion and ratio to pasta.
What size is your insta pot?
Hi Susan, it is an 8 quart, this is the one I have.
Hi, can you confirm whether the pasta should be cooked or uncooked when it is added to the Instant Pot. I’m assuming uncooked but wanted to make sure.
Thanks
Uncooked
This Instant Pot pasta was amazing. It’s so easy my girls (13&10) made this. It is so adaptable to your linkings if you wanted to add other vegetables or plant based protein. It all comes together so quickly so have everything ready/prepped to go. We will definitely make this again!!
My family made this just the other night. My daughters made this. It’s simple and comes together so quickly. You can add other veggies or plant based protein to it as well. We will definitely make this again!
Thank you so much John for taking the time to leave a lovely review! So wonderful that your daughter’s made it!
Just made this and it was delish even though I had no fresh basil and I had to use yellow onion instead of red. One pot and delish = winner !
Wonderful to hear!
Brandi, Once again you’ve hit this OUT OF THE PARK! Just made this last night for the first time and it was enthusiastically given a thumbs up by all family members! I especially love that it took ingredients that were already in my pantry and fridge. Prep was a breeze, the cooking part was speedy, and the results were nothing short of amazingly delicious. And it made a lot, so that we have leftovers for lunch today….my mouth is watering just thinking about it.
Thanks for all the recipes you create and share with us Brandi!

Aww, this comment was so sweet, so glad you loved it so m uch Lillianne!
This recipe was super easy and delicious! The hubby even went back for seconds! This is definitely going into the regular dinner rotation! Fast, easy and delicious! I might add some chopped spinach at the end next time too.
So happy to hear you and your hubby loved it Lisa!!
very tasty! We made it tonight for dinner and all the seasonings went together very well!
So glad to hear that Carla!
OMG!!! Are you kidding me? I bought an IP just to make this dinner (plus I knew you would be making more IP recipes🤪). It was so incredibly flavorful! The pasta was a perfect al dente and the sauce was sooooo rich! My husband LOVED it and asked when I would be making your next IP recipe. One pot, one measuring cup and one measuring spoon. Unreal 😻
Yay, that is so amazing to hear Marie!! Thank you so much for making it and leaving feedback! Did you see the curry I just posted as well? It’s another IP recipe 🙂
I’m really slack about reviewing or commenting on recipes I pull from the Internet. I’ve used quite a few of years in the past, and had good results. This was just so delicious and easy, I know it will be a standby favorite. I’ve never been a huge fan of the red pasta sauces, but the cashew cream or coconut milk ones add so much fat. Adding the balsamic and maple syrup transformed the flavors and since it was so quick and easy, I did make up your vegan lemon parmesan and add that. Amazing! I’ll be asking for your cookbook for Christmas this year! Super yummy meal with plenty of leftovers. I did add one large zucchini in chunks and about a half cup of sliced baby portobellos and it didn’t impact the cooking time at all.
Thank you so much for this awesome review Melissa!
Easy to make and so so tasty!! Thank you!! 🙂
Wonderful to hear Esther!
Really really excellent, thank you so much for the recipe!!!!
So happy to hear that, thank you Phil!
Ah Brandi, it’s so refreshing to have someone whose recipes you can try with 100% faith that they’re going to work out perfectly. I love that about your recipes. This was the same – loved it and it was perfect. I did actually use a gluten free bean based pasta so I did have to alter the time slightly, as you’d suggested. I went with the rule I saw online of “halve the suggested cooking time on the packet and minus one minute.” I did that, with your 5 minute release and it was perfect. Looking forward to trying all of your IP recipes.
You are so sweet, thank you so much Louisa!! So happy you love my recipes!
Tasty! I made a half recipe with modifications: about 1 c chopped tomatoes and 2 T tomato paste diluted with water as I had no tomato sauce, no sweetener as I find I usually prefer omitting the sweetener in savory recipes and twice as much balsamic vinegar (1 T for 1/2 recipe) as goofed…but it’s very good!!
Made this tonight and it was a hit! The girls want me to make it every day. Used whole wheat rotini and it was just perfect. Another one in the rotation!
Every day, that is awesome Elyse!!
Thank you so much for your recipe! It turned out so delicious 😋! Everyone gobbled it up and they could hardly tell it was vegan, it was so hearty!
