Instant Pot Lasagna Soup – Vegan Lasagna Soup with Red lentils, lasagna noodles, veggies, and basil. 1 Pot weekday meal. Vegan Nut-free Recipe. Saucepan option Can be gluten-free. Jump to Recipe
Pasta, tomatoes, herbs, red lentils, pesto and garlic bread. I mean, you cannot go wrong with all these together. This soup is satisfying and comfort food made in 1 pot and ready within minutes. It comes together quickly with short active time. Make it in the Instant Pot (pressure cooker) or a Saucepan (see recipe notes), but definitely make it. I love the soup with some extra garlicky topping like garlic bread or garlic olive oil and some fresh basil or pesto. Lentils make up the protein. If using brown lentils, use cooked lentils. Veggie crumbles will also work wonderfully.
To make this gluten-free, use glutenfree pasta or add more lentils or some quinoa and omit the pasta. Easy and Delicious Soup that is versatile and pleases everyone.

This thick luscious meal is more a lasagna casserole than soupy soup. You can add in other ingredients such as veggie crumbles, add more water/broth for thinner soup and so on. The flavor of the soup builds up with the toppings, so definitely use them generously. You can also add in some more herbs and some pesto before pressure cooking and then fold in some mozzarella or vegan ricotta into the hot soup.
Build it up to preference make this your own fave meal!

Tips for making a great Lasagna Soup in a Pressure Cooker
- Mix the lasagna noodles really well before closing the lid, so they don’t stick to each other under pressure.
- Double: Cooking time is the same for doubled recipe. Use slightly less than double amount of pasta, use crinkly noodles or other pasta rather than flat noodles if they tend to stick too much. (more noodles means more surface area to stick). No boil as well regular noodles work. Use more seasoning and salt, a bit more than double as more volume dilutes the flavors a bit.
- Burn errors: Mix the soup really well before closing the lid to pick up all browned onion/veggies. Any scorched veggie at the bottom tends to scorch more under pressure causing burn errors.
- Red lentils (split and skinned lentils) are quick cooking and will cook in the time of the recipe. Whole dried lentils will need a much longer cooking time and that will overcook the noodles and veggies. Use pre cooked whole lentils instead.
- The veggies, noodles and lentils will get affected if trying to make a triple or larger batch. With more volume, the pot takes longer to come to pressure and hence will cook the ingredients longer. Be mindful of the extra cooking time.
- Fold in some vegan mozzarella while the soup is still hot and top with more for a more lasagna like soup. Also do not skip the pesto.

- 2 tsp italian seasoning, (1 tsp basil and 1/2 tsp oregano, parsley, generous dash of thyme/sage and rosemary)
- 1/4 tsp each onion powder, , garlic powder
- 1/2 to 3/4 tsp salt, (depends on if there is salt in the tomatoes or other seasoning, I use 3/4 tsp with)
- 2 cups water or veggie broth, (2.5 to 3 cups for soupier or if using whole grain noodles or with more veggies)
- 5 oz lasagna sheets, , broken into small pieces, or use pasta of choice (I use no boil as they work out the best)
- dash of black and white pepper
- pepper flakes to taste, , i use about 1/3 tsp
- 1 tbsp nutritional yeast
- 1 cup packed spinach, , optional
- vegan pesto, vegan ricotta or mozzarella, vegan butter/ garlic bread to serve, optional
- a tbsp tomato paste, lemon, fennel seeds (optional add ins)
Instructions
- Heat oil in Instant pot on saute mode. When hot, add onion, garlic and a pinch of salt. Cook for 2 mins, stirring occasionally. (See Recipe notes for Saucepan instructions )
- Add veggies and mix in. Add red lentils, tomato purée, tomato, salt, seasoning, onion powder, garlic powder and mix in. Add a tbsp of tomato paste for additional tomato flavor (optional). Add lasagna sheets and water and mix in. (make sure to use small pieces and mix them in well else they tend to stick)
- Close the lid and Pressure cook on manual hi for 3 mins **. Let the pressure release for 10 minutes, then if there is still pressure in the pot, manually release carefully and open.
- Mix in the black pepper, pepper flakes and nutritional yeast. Taste and adjust salt and flavor(italian herbs, onion/garlic powder). Add some more salt, broth, tang(lemon) if needed to balance.
- Fold in the spinach if using. Let sit for a minute. Then serve with pesto/basil and/or vegan ricotta/mozzarella, and garlic bread. You definitely need some vegan cheese for a more lasagna like flavor. Fold in some into the soup while still hot and use more for garnish.

Notes
- Burn errors: Mix the soup really well before closing the lid to pick up all browned onion/veggies. Any scorched veggie at the bottom tends to scorch more under pressure causing burn errors. Add more liquid. Readers often double the liquid, veggies and sauce ingredients and don’t double the pasta.

This was EXCELLENT!!! Just made it, planned to save a serving, hubby and I devoured the whole pot. This was better than lasagna I’ve baked in a pan that took three hours. Thank you SO MUCH!
This is our new favorite recipes — thank you! I use a 6qt & have had no problems with sticking or burning. I followed the recipe perfectly the first time, & added an extra cup of liquid the next time. I was afraid to double it until I become more experienced with the pot, but after reading your comment that no cook time adjustment is necessary I will double next time. It is so good!
I made this Insta Pot lasagna yesterday for lunch. It was so easy and delicious! I doubled the recipe and it worked out fine. I made a creamy vegan cheese sauce that I used last time I baked a lasagna adding it in after pressure was released. I added green green chard at that time too. I’m still new to using my Instant-Pot so your recipe and tips were very helpful.
Thank you for taking the time to create this recipe and the many others you share on this site. I’ve tried several other recipes you’ve created and enjoyed all of them!
Thats awesome! yes a cheese sauce drizzle will be perfect
Delish! Even though I set the time a little too long, maybe reading the instructions on my new Crockpot/instantpot would be a smart thing LOL. Def will be making this again. I sauteed mushrooms, removed and then added after. Do you know if they would be ok to leave in with everything else?
thanks!!
yes you can leave them in, saute just a little as they will continue cooking with the rest
appreciate it! Making this again this weekend!
This recipe is TO DIE FOR!!! My family couldn’t believe there was no cheese in this soup LOL. Finally, a vegan recipe that tastes incredible. Vegan Richa you knocked it out of the park thank you!
yay!
I adore your cookbooks.I really really wish they were printed in a spiral bound plastic coated form.That would be fantastic for cooking.Maybe you could suggest that to the publishers so when we cook we can just flip to the page & wipe them off if we get something on them. Keep up the great work.I have never made a recipe of yours I have not liked. Thank you.
Thank you Paula. I will suggest that to the publisher.I think you can take the book to binding place and they convert it for you too
This recipe was amazing !
I made it twice
I didn’t try using fennel seeds in this recipe but I was a little afraid – has anyone else tried it?
they add a sausagey flavor
Am I putting boiled pasta or uncooked lasagna pasta in the mix? Did I missed it? when you said that you need to put it in pressure cooking, do mean put the valve in “sealed” rather than “venting?” Thank you!
its uncooked pasta and it gets cooked under pressure.Yes the valve is on sealing. i’ll make this clear inthe instructions
If I boil them separate, is there still an advantage to cook the rest/sauce in the IP, or just do stove top? Trying to figure out the best way to make this with gf lasagna noodles. Any suggestions appreciated!
with the separate noodles either way to make the sauce will work. Instant pot will just keep your hands free as you dont have to stir or keep an eye on the stove.
This is the 2nd time I’ve made this, and I will be making it regularly. It is superb! Took it to a party last night and it was gobbled up by vegans and non-vegans alike. Thank you!
awesome!
