Let’s Get Cooking! (The Step-by-Step)
Grab your big soup pot or Dutch oven. This is where the magic happens. Follow these steps and you’ll be eating in no time.
- Heat the olive oil in your pot over medium heat. Add the diced onion and cook for 3-4 minutes, until it starts to soften.
- Add the garlic, mushrooms, Italian seasoning, and red pepper flakes. Cook for another 5-7 minutes. The mushrooms should release their water and start to brown. This builds a flavor foundation.
- Pour in the entire jar of marinara and the vegetable broth. Give it a good stir and bring it to a simmer.
- Once simmering, add the broken lasagna noodle pieces. Stir to submerge them. Let the soup cook for 10-12 minutes, stirring occasionally so the noodles don’t stick.
- While the soup cooks, make the cashew cream. Drain your soaked cashews. Add them to a blender with the 1 cup water, nutritional yeast, lemon juice, and salt. Blend on high until it’s completely smooth and creamy. This takes about 1-2 minutes.
- Check your noodles. They should be tender. Reduce the heat to low. Stir in the fresh spinach until it wilts.
- Now, pour in that glorious cashew cream. Stir everything together until the soup is beautifully creamy and unified. Taste it! Add more salt and pepper if needed.
- Serve immediately. Top with vegan parmesan, fresh basil, or a dollop of vegan ricotta if you’re feeling fancy.
What to Serve With This Dish
This soup is a full meal. But if you want to round it out, keep it simple. We’re not making a second complicated project.
A thick slice of crusty garlic bread is perfect for dipping. A simple green salad with a tangy vinaigrette cuts the richness. Or just grab a bag of pre-washed salad greens. No shame in that game.
Make This Recipe Your Own (Quick Swaps)
Make it work for you! Use what you have. That’s the busy cook way.
No cashews? Use 1 cup of raw sunflower seeds for the cream. Or, stir in a cup of canned full-fat coconut milk for richness (it will taste slightly coconutty).
Add a protein. A can of drained and rinsed lentils or white beans stirred in with the broth is fantastic. For a “meatier” bite, use a plant-based ground “beef” crumble. If you’re not strictly vegan, another fantastic one-pot option is this Creamy Garden Chicken Lasagna Soup.
Different greens? Kale works great. Just chop it small and add it a minute earlier than spinach so it softens.
How to Store Leftovers (If You Have Any!)
This soup stores like a dream. Let it cool completely, then pop it in an airtight container in the fridge.
It will keep for 4-5 days. The noodles will soak up more broth, so it gets thicker. Just add a splash of water or broth when you reheat it to bring it back to soup consistency. Reheat on the stove or in the microwave.

FREQUENTLY ASKED QUESTIONS
Can I make this in an Instant Pot?
Absolutely! Use the Sauté function for steps 1 & 2. Add everything except the cashew cream and spinach. Cook on High Pressure for 5 minutes. Quick release, stir in spinach and cream.
My soup got too thick overnight. Help!
No problem! The noodles are thirsty. Just add more broth or water when you reheat it, a little at a time, until it’s your perfect consistency.
Can I use regular lasagna noodles?
Yes, but you must boil them first. The “oven-ready” kind are a major time-saver because they cook right in the broth. If using regular, cook them separately, then add to bowls before ladling in the soup.
See? Dinner doesn’t have to be a battle. You just made a pot of comfort that’s fast, healthy, and seriously delicious. You won the weeknight. For another creamy, dairy-free favorite, my Vegan Potato Soup is the ultimate cozy meal.
