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!

You definitely dont want to skip some vegan cheese (mozzarella or ricotta) and pesto!

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.

My husband and I love this recipe! We’ve made it twice with gluten-free pasta and serve it with cashew ricotta stirred in, with a dollop on top! Yum!! We’re not vegan but we don’t even miss the meat and dairy! We thank you for sharing your recipe!
Excellent recipe! Very unique taste and texture. I have made so many of your recipes, that I should be considered your disciple/ student. Thank you for sharing these recipes.
wow – I could use an apprentice!! 🙂
So good! Just found your site while searching for a potato recipe.
This made such a good dinner. Looking forward to leftovers!! And I can’t wait to try more recipes! 😊
THANK YOU – Go for it – you won’t be disappointed
This recipe turned out amazing! 🙂
yay!!!! my goal has been realized
Outstanding and seriously such a quick meal, especially if you have already pre-cut some onions, carrots and peppers.
thank you kindly, exactly- a little pre – preparation goes a long way
Fantastic! It hit all the right spots. So easy and quick to prepare. So incredibly satisfying and delicious!
I Love this recipe! Due to the fact that I am the only one eating it… have you ever pressure canned it?
Please lmk if so, what you did… thank you 😊
Thank you!! I have not yet tried that… sounds interesting.
I’m new to instant pot cooking. I stumbled on your recipe and have always loved the recipes in your Indian Kitchen cookbook, so I thought I’d try this.
Hubby and I just finished this lasagna soup. YUM! So satisfying. I’m glad I doubled the recipe.
wow!!! doubled right away – some things you just know! thank you kindly Kat. I’m glad to hear it. The instant pot is amazing, right?
This recipe is iconic to me and it’s old hat at this point when I make it. Fool proof, flavorful, allows for creativity or staying simple. Whenever my non Vegan husband gets to make a recipe request he always goes for this one! It’s kid friendly, easy to reheat and the clean up is easy enough. Vegan Richa recipes always leave me with the same “Finally! That craving is curved.” feeling. This one just makes me as usual miss nothing about the meat or cheese days. Keep it up, I really love your work.
Last time I made this I cooked up some tofu sausage, that is a fantastic addition. It’s one of the highest protein enriched meals I eat when I go serve it up that way.
wow – that’s what I love to hear!! thank you so much.
Delicious! Perfect meal to make to meet my sons girlfriend.
