- One pot cooking means less cleanup and more time to chill or do whatever you love.

- Natural release lets everything settle so you don't end up with a messy splatter or mushy noodles.
Your Simple Ingredient Checklist
First things first, you gotta have the right stuff ready. It starts with half a tablespoon of oil to get your sauté going. Then chop up one small onion, diced just right so it softens good in the pot. Don’t forget 4 cloves of garlic minced fine to bring that punch of flavor.
Next up are your seasonings: 1 and a half teaspoons Italian seasoning, a teaspoon of onion powder, and half a teaspoon paprika to sprinkle some warmth. Toss in 1 and a quarter teaspoons of sea salt but you can add more or less as you like. Black pepper’s a must to taste.
For the protein and body, grab half a cup of dried red lentils and 5 cups of low sodium veggie broth or water for the base. Add half a cup dairy-free milk or cream to keep it creamy but plant-based. Tomato sauce and a tablespoon of thick tomato paste give it that rich red sauce feel. Break six lasagna noodles into chunks (gluten free if you choose).
To finish, you use a quarter cup of nutritional yeast, a third cup of cashew butter for creaminess, a tablespoon lemon juice to brighten it up, plus optional red pepper flakes, vegan ricotta or mozzarella, and fresh herbs for garnish.

Walking Through Every Single Move
Heat your pot with that half tablespoon oil over medium heat. Toss in your diced onion and cook till it’s translucent, about five minutes. You’ll see the edges start to soften and the smell fills the kitchen.
Next, add minced garlic plus Italian seasoning, onion powder, paprika, salt and pepper. Stir it all for a minute until you can smell the spices getting cozy together.
Pour in the dried lentils and vegetable broth and crank up the heat till it boils. Once boiling, reduce heat to a simmer letting the lentils cook about twenty minutes until tender pull happens.
About five minutes before it’s done, break those lasagna noodles into bite-sized pieces right into the pot. Stir occasionally so noodles don't stick. Cook until noodles are al dente.
Turn off the heat and add in your dairy-free milk, tomato sauce, tomato paste, nutritional yeast, cashew butter, and lemon juice. Stir well to get that creamy, cheesy texture going.
Give it a taste, tweak the salt or pepper if it needs. Let the soup sit for a few minutes on natural release after sealing the pot, so everything melds together nice. Then serve up, garnish with vegan cheese or fresh herbs if you want.
Smart Shortcuts for Busy Days
- Use pre-minced garlic or garlic paste so you skip chopping and still get big flavor.
- Grab pre-diced onions from the store to save yourself some prep time.
- Swap dried lentils for canned ones when you are in a real rush—rinse them well though.
- Frozen diced onions or garlic also work fine if fresh isn’t around.
- If you got leftover cooked noodles, add them after the soup’s done to heat through, so they don’t mush.
Your First Taste After the Wait
The first spoonful kinda warms you like a hug, rich with tomato tang and that cozy cashew creaminess you never thought would work so good in soup. You feel the gentle tender pull from the lentils and the soft noodles mingling together.
There’s that hint of Italian herbs and paprika teasing your taste buds, with just enough pepper heat to keep it interesting. You might even get a touch of zing from the lemon juice peeking through, making every bite feel bright and fresh.
The vegan cheese on top melts in slow, adding extra creaminess and that comforting lasagna vibe. Every mouthful kinda reminds you of home cooking but way easier and quicker to get on the table.
Your Leftover Strategy Guide
To keep your soup tasting fresh, store leftovers in airtight glass containers. They hold in the flavors and avoid weird fridge smells.
You can keep soup in the fridge for about four days without issues. When reheating, use medium heat on the stove or microwave, stirring halfway through so the noodles don't get mushy.
If you want long term, freeze the soup but remember noodles can get soft after thawing. Best to freeze soup separate from noodles if you wanna keep texture.
Reheat frozen portions slowly on stove, letting it come to a gentle simmer. Add a splash of water or broth if it gets too thick. You can toss in fresh noodles at serving if old ones feel off.
Everything Else You Wondered About
Can I use different types of noodles? Totally. You can switch to gluten free noodles or even smaller pasta shapes but add them at the same time as lasagna noodles.
Is cashew butter necessary? It really helps with creaminess but you can swap in tahini or blended soaked cashews if that’s what you got.
How do I know when lentils are done? You watch for that tender pull when you stir and taste. They should be soft but still hold shape.
Can I double the recipe? Sure thing! Just remember your pressure cooker size limits and maybe increase cooking time slightly.
What’s the difference between natural release and slow release? Natural release means you let the pressure come down on its own after cooking stops, no touching valve. Slow release means you ease the pressure out little by little manually to avoid splatters.
Can I add other veggies? You can, but add quick cooking kinds like spinach or mushrooms near the end so they don’t overcook.
