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!

Course Dinner, pasta
Cuisine Italian, Vegan
Yields 3 -4 servings

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.

    We’ve made this recipe twice now! It’s amazing! I will say I did the recipe exactly both times. In the future, I think I’ll leave out the agave because the balsamic vinegar that I have is sweet on its own. Other than the sweetness this recipe is killer!

    Tried this recipe for dinner and it was so easy and fantastic! You were so right about the sauce having a great depth of flavor. I think you could easily add some veggies to it too. Will definitely be making this one again! Thank you for sharing such a tasty recipe!

    If doubling the recipe do you pressure cook for 10 min? Then 10 min pressure release before manually pressure releasing the rest? Thanks!

      Hi Tara! I’ve never tried doubling it, but the cook time shouldn’t change since the pasta still needs the same time to cook. I would follow the same directions. Hope it turns out the same.

    Thank you for such a wonderful, tasty meal for my family and me! We have decided to do our little part and begin having meat-free Mondays; this was our first official meal for it!
    I’ll definitely be adding this to our rotation and checking out your other recipes!

    I usually never leave comments on recipes but I make this recipe so much I feel like I have to! I’m a student and barely have anytime to cook so this recipe is absolutely perfect! It tastes awesome and cooks perfectly in the instant pot (I often have issues with the burn notice with other recipes but that has not happened a single time with this recipe). I use chickpea pasta instead by pressure cooking for 3 minutes with 4 minutes natural release. Thanks so much for this awesome recipe!

    Brandi, this was delicious! I used capenelle pasta, what I had & power greens. The black olives were a nice touch. Thank you!

    I have had my eye on this recipe for awhile. Because you mentioned the importance of the dark balsamic vinegar, I have been to 4 stores trying to find those brands without luck. Is it fair to say that any dark balsamic vinegar should do the trick? I have one from Costco and one from Trader Joe’s.

        Thank you for the reply! I made it with the Costco’s balsamic vinegar and it was “very good” to quote my husband. I used Trader Joe’s organic “brown rice and quinoa” fusilli pasta so I made some adjustments so it did not turn to mush. Added additional 1/2 cup water, set instant pot to cook for only 2 minutes then released pressure after 5 minutes. Happy to say it was perfect! Phew!

    Wow, this was delicious! I browned some plant-based Italian sausage and added it once the pasta was done. I love how such simple ingredients came together to make a wonderful dinner!
