Ingredients You’ll Need for Vegan Lasagna Soup

Let’s keep things real here. You probably have most of these in your kitchen already.

Here’s what goes into the base recipe:

• ½ tablespoon oil
• 1 small onion, diced
• 4 garlic cloves, minced
• 1½ teaspoons Italian seasoning
• 1 teaspoon onion powder
• ½ teaspoon paprika
• 1¼ teaspoons sea salt (or to taste)
• Black pepper to taste
• ½ cup dried red lentils (rinsed)
• 5 cups low-sodium vegetable broth or water
• ½ cup dairy-free milk or cream
• ½ cup tomato sauce (passata works beautifully)
• 1 tablespoon tomato paste
• 6 lasagna noodles, broken into bite-sized pieces (gluten-free if needed)
• ¼ cup nutritional yeast
• ⅓ cup cashew butter (or almond butter/vegan sour cream)
• 1 tablespoon lemon juice
• Red pepper flakes (optional, for heat)
• Vegan ricotta or mozzarella (optional, for garnish)
• Fresh herbs like parsley or basil for garnish

A Quick Note on Substitutions

• Nut allergy? Swap the cashew butter for sunflower seed butter or a nut-free vegan cream.
• No tomato paste? Just increase the tomato sauce by a few tablespoons.
• Spice-lover? Add extra red pepper flakes or a dash of hot sauce.

This soup is forgiving. Make it work with what you have.

How to Make Creamy Vegan Lasagna Soup (Step-by-Step)

Here’s how I get it on the table in under 30 minutes—even with kids running around the kitchen.

1. Rinse the lentils

Run cold water over them in a sieve. Set them aside while you prep everything else.

2. Sauté the aromatics

In a large pot, heat the oil over medium heat. Add diced onion and sauté for 3-4 minutes until soft. Stir in minced garlic and cook for another minute.

3. Build the soup base

Add the Italian seasoning, onion powder, paprika, salt, pepper, red lentils, tomato sauce, tomato paste, cashew butter, and broth.

Whisk it all together. Let it come to a gentle boil.

4. Add the lasagna noodles

Break them into small pieces with your hands and stir them in.

Let the soup simmer for 9-10 minutes until the noodles are tender.

5. Stir in the creaminess

Turn off the heat. Add dairy-free milk or cream, lemon juice, and nutritional yeast. Stir gently to blend.

6. Taste and adjust

Now’s the time to season it up. Add more salt, pepper, or a pinch of red pepper flakes for heat.

7. Serve and garnish

Ladle into bowls and top with vegan ricotta or shredded mozzarella and fresh herbs.

It’s rich, cozy, and incredibly satisfying.

Tips for Making This Recipe Your Own

Every time I make this soup, I tweak it just a little. That’s the beauty of it.

Here are some ideas if you want to mix things up:

• Add veggies: Stir in chopped spinach, kale, or zucchini during the last few minutes of cooking.
• Swap noodles: Use gluten-free pasta, rotini, or even broken spaghetti.
• Make it nut-free: Replace cashew butter with sunflower seed butter or vegan cream cheese.
• Boost the protein: Add canned chickpeas or white beans for extra heartiness.
• Spice it up: A swirl of sriracha or a pinch of chili flakes goes a long way.

You could even draw inspiration from this vegan sausage broccoli orzo skillet if you’re craving more veggie-rich pasta dinners.

How to Store and Reheat Vegan Lasagna Soup

This soup thickens as it sits because the noodles keep absorbing the broth. That’s not a bad thing—it turns into a thick, creamy stew by the next day.

Here’s how I store and reheat it:

• Refrigerator: Store in an airtight container for 4–5 days.
• Reheat: Warm on the stove or microwave. Add a splash of broth or plant milk to loosen it up.

It actually tastes even better the next day.

This soup can totally stand alone. But if you’re feeding a hungry crowd or want to round out the meal, here are a few ideas:

• Crusty bread or garlic toast for dipping
• Simple green salad with balsamic vinaigrette
• Roasted vegetables like broccoli, carrots, or Brussels sprouts
