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.

Ingredients
- 1 tsp oil
- 1/2 onion, chopped
- 4 cloves of garlic, chopped
- 1 cup veggies - combination of peppers, , carrots, zucchini
- 1/4 cup red lentils, (uncooked) - quick cooking red lentils (split ones) also called masoor dal

- 1 to 1.5 cup diced tomato
- 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.

What is substitute for yeast?
I don’t have it handy
its nutritional yeast which is inactive and adds a bit of cheesy flavor. you can omit it. the soup is flavorful enough
Omg, I love you. New staple.
This had such rave reviews that I had to try it for myself. Did it live up to the hype? Absolutely!!
This was phenomenal!
For the vegetables, I used 1 zucchini and 1/2 green pepper.
I think when I serve it to guests, I will serve it over cauliflower rice so that I can give them a smaller portion of the soup to make it last longer.
Many thanks!!
awesome!!
I don’t know what i did wrong. It looks and smells delicious but it tastes so bland. It’s so strange. I followed the recipe exactly but it’s really lacking something.
I would like to solve it bc it smells soooo good!
Got my Instant Pot today and made this fantastic soup. It is delicious and I cannot wait to have people over for dinner so I can wow them with this vegan dish!
How would you successfully double or more this recipe without changing consistency or flavor! I need to serve 8-10?
You can triple it for 8-10 people. Use a bit less liquid than 3 times. Also you want to use crinkly lasagna noodles or other pasta as the plain lasagna noodles will tend to stick because they will get heavy with the higher amount and the flat noodles with more surface area in contact with each other will stick. Adjust the consistency once you open the lid with additional tomato or flavor if needed.
If I double the recipe, does the cooking time change or remains the same? Logically speaking, I think it will take longer for the instant pot to come to high pressure.
Any thoughts?
Yes the coming to pressure time will increase. If you make a much larger helping (4 times or more), then the veggies might be a bit overcooked because of the added coming to pressure time where they already start cooking. Cook time remains 3 mins for double/triple.
I think I’m going to modify and put some of the veggies that get over cooked easy after the pasta and lentils are done. Maybe that might help. Thanks!
I doubled it tonight in my 6qt and it worked great
Hello! This recipe looks amazing. I’m cooking this for my fam tomorrow night but I do not have an IP. When you say to add 3c of water – do you mean in addition to the 2? Or just 3 instead of 2. Sorry if this is a dumb question, I’m just a paranoid recipe follower, lol. -_-
its 3 total instead of 2. In a saucepan there is more evaporation , so you need a bit more liquid
Thank you! And thank you for the recipe. 🙂
Hi, I just got an instant pot so I’m new to this way of cooking. So far I made lentil taco meat and it was a hit. For the viggies in this recipe can I use a frozen medley of a combination of peppers , carrots, zucchini? Will this alter cooking time? So excited to try this!
yes. it will work fine as the instant pot will add a min or so in coming to pressure time by itself.
This is insanely delicious! So fast and easy with the instant pot. Too bad this only has a five star rating system. This one is easily a six star!
yay! awesome! <3
