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.

- 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.

Delicious the first night, and do I dare say even better as leftovers?! Mmmmm!!!
So glad you liked it!
This was absolutely delicious. If I wasn’t watching what I eat these days, I’d probably eat the whole thing up in one sitting. I followed the recipe to a T. I did add extra vegetables and spinach, so I added a little bit more water but not a lot. I didn’t have No boil lasagna so I put the regular lasagna pieces in a pot of water while I cooked my veggies. I over cooked a little bit, but it still came out great. Can’t wait for leftovers.
Yay!
Absolutely delicious and so easy to make. This is going to be a regular for me. I like how the recipe is flexible with using any veggies to hand and your choice of pasta. Very flavourful.
Happy to hear!
Very spontaneous dinner recipe tonight as I realized I had most of the ingredients in my pantry! My husband and I loved it! Very hearty, delicious soup that tastes like rich ministrone, but if I used lasagna noodles (I used whole wheat pasta) and added vegan ricotta or mozzarella I imagine it the flavor would be closer to lasagna. I used canned tomato sauce and diced tomatoes instead of puree or fresh tomatoes, which made it super easy!
Glad it worked out!
This is a great soup! Cozy and full of flavor-all the comforts of lasagna with half the work. Yum!
Glad you enjoyed it!
Hi…I’m new to Instant Pot cooking, and was wondering what size IP are you using with your recipes in the 31-day challenge (mine is a 3 qt)? Thanks!
I use 6 qt. This recipe works in 3 qt as well
Easy and very delicious! I’ve made this a half-dozen times and it always gets rave reviews! Instead of folding in spinach, I fold in baby kale – so good! Thank you!
Genius!! Baby kale is great with this.
Made this tonight for my husband’s birthday dinner. Did the stovetop version. Used gluten-free mafalda pasta (looks like little lasagna sheets). Turned out very well with pesto and some vegan mozzarella mixed in. Husband thought it was great!
So happy to hear!
Loved it! I doubled the recipe and it turned out very well. the whole family loved it…even the non-vegans
Yay!! It’s always a hit with the little ones.
I absolutely love this recipe and have n my are it many times – I love that any veg can be swapped in easily – whatever’s in the fridge – and it’s a healthy easy complete meal all in one put. Quick to make and freezes well for lunches too. Thank you !
Thank you for making my recipes!!
