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.

Made this tonight and the fam actually LOVED IT!
excellent!
This was so easy to make and so delicious. Will definitely make again. Thank you for this great, easy to follow recipe.
So glad you enjoyed it, thanks for the review!
I used gf lasagne made from corn, and you’re right they do tend to stick, but the taste was excellent. I didn’t have any leafy greens on hand, so I used mushrooms. Next time I’ll use a different pasta.
I also got my first electric pressure cooker just two days ago and didn’t feel like dealing with something new, so I made it on the stovetop.
I wish I had made double the amount!
thank you! maybe you can try it next time, soon you’ll be making everything in it!
I love this recipe; so easy and SO DELICIOUS!! Thank you for sharing 💚
So glad you enjoyed it!
This was really good and super easy.
Awesome! (Like all your recipes!) Does it freeze well?
I made this as directed and it burnt to the bottom of the instant pot before reaching pressure, I cooked for longer on the stove then put it back in the cleaned instant pot with some extra water, it quickly burned again. What am I doing wrong here? (I made sure there were no burnt or stuck bits after sauteeing)
It’s probably the pot. Some instant pots heat unevenly or hotter and cause certain areas to heat up a little more which can sometimes burn the food. Sometimes the inner pot is defective. This overall causes thicjer pasta dishes or tomatoe dishes to generally scorch the bottom. Once you switch off sauté let the mixture cool a little bit also use a bit more liquid in the recipe states and try.
Thank you – I finished cooking it on the stove and it was delicious:)
I finally got around to making this and it was so simple to make and it turned out sooo good! I probably used closer to 2 cups of veggies (bell pepper, zucchini, carrot and mushrooms) so I increased the water to 2.5 as suggested. Some of my lasagna did stick together but I think I made a lot of the pieces too small. The only reason my we didn’t eat the whole pot of soup was because my hubby wanted to save some for the next day for lunch. I will definitely make this again and double from now on! Thanks for a great recipe!
excellent!! tastes even better the next day. maybe a double batch is in order next time!!
If I double this recipe, how much time should I give it? Any thoughts on this? Our family loves it but we have just enough for the 5 of us. I would love to have a few leftovers and I think there is still plenty of room in the pot without having any issues. Thanks!
Cook it for the same time as a single batch, just make sure you have enough room in your Instant Pot.
Hi Richa, do you know if we can freeze it?
yes
