Ingredients

For the Soup

2 tablespoons olive oil
1 medium yellow onion, diced
3 cloves garlic, minced
1 medium carrot, finely diced
1 bell pepper, diced
1 pound vegan ground meat or plant-based crumbles
1 teaspoon Italian seasoning
1 teaspoon dried oregano
1/2 teaspoon smoked paprika
1/2 teaspoon red pepper flakes, optional
1 teaspoon salt
1/2 teaspoon black pepper
2 tablespoons tomato paste
1 can (28 ounces) crushed tomatoes
1 can (14.5 ounces) diced tomatoes
5 cups vegetable broth
8–10 lasagna noodles, broken into bite-sized pieces
1 tablespoon balsamic vinegar
1 teaspoon sugar, optional
2 tablespoons chopped fresh basil or parsley

For the Vegan Ricotta Topping

1 cup dairy-free ricotta
1/4 cup nutritional yeast
1 tablespoon fresh lemon juice
1 tablespoon chopped fresh basil
1/4 teaspoon garlic powder
Salt and black pepper, to taste

Instructions

1. Sauté the Vegetables

Heat the olive oil in a large Dutch oven or soup pot over medium heat.

Add the diced onion, carrot, and bell pepper. Cook for about 5–7 minutes, stirring occasionally, until the vegetables begin to soften.

Add the minced garlic and cook for another 30 seconds.

2. Add the Plant-Based Meat

Add the vegan ground meat or plant-based crumbles.

Cook for approximately 3–5 minutes, breaking it apart with a wooden spoon as it cooks.

If you’re using a variety that doesn’t need browning, simply cook it until warmed through and lightly browned.

3. Add the Seasonings

Stir in the Italian seasoning, oregano, smoked paprika, red pepper flakes, salt, black pepper, and tomato paste.

Cook for about 1–2 minutes.

This short step helps the tomato paste and spices develop a deeper flavor.

4. Build the Soup

Pour in the crushed tomatoes, diced tomatoes, and vegetable broth.

Stir everything together and bring the soup to a gentle boil.

Reduce the heat and let it simmer for about 10 minutes.

5. Add the Lasagna Noodles

Break the lasagna noodles into smaller pieces and add them directly to the soup.

Stir well to prevent the noodles from sticking together.

Simmer for approximately 10–12 minutes, or until the noodles are tender but still slightly firm.

Stir occasionally while the pasta cooks.

6. Finish the Soup

Once the noodles are cooked, stir in the balsamic vinegar.

Taste and adjust the seasoning as needed.

If the tomato sauce tastes particularly acidic, a small amount of sugar can help balance the flavor.

Stir in the fresh basil or parsley just before serving.

7. Make the Vegan Ricotta

While the soup is simmering, combine the dairy-free ricotta, nutritional yeast, lemon juice, fresh basil, and garlic powder in a small bowl.

Season with salt and black pepper to taste.

Mix until creamy and well combined.

8. Serve

Ladle the hot lasagna soup into bowls.

Add a generous spoonful of the vegan ricotta mixture on top.

Finish with fresh basil, parsley, or a sprinkle of nutritional yeast.

Serve immediately while hot.

Tips for the Best Vegan Lasagna Soup

Don’t overcook the pasta. Lasagna noodles continue absorbing liquid after cooking, so it’s best to stop when they’re just tender.

Use a flavorful vegetable broth. Since the broth makes up a large portion of the soup, a good-quality broth adds plenty of depth.

Don’t skip the tomato paste. It gives the soup a richer, deeper tomato flavor.

Add the balsamic vinegar at the end. A small amount brightens the tomato sauce and balances the richness.

Adjust the consistency. If the soup becomes too thick, add another splash of vegetable broth before serving.

Easy Variations

Add More Vegetables

You can add mushrooms, zucchini, spinach, kale, celery, or chopped tomatoes.

Make It Spicy

Add extra red pepper flakes or a pinch of cayenne pepper for a spicy kick.

Use Different Pasta

If you don’t have lasagna noodles, broken-up lasagna sheets aren’t essential. Mafaldine, bow-tie, penne, or another short pasta can work as well.

Make It Extra Creamy

Stir a small amount of vegan cream cheese or cashew cream into individual bowls before serving.

What to Serve With Vegan Lasagna Soup

This soup is filling enough to serve as a complete meal, but it pairs wonderfully with:

Garlic bread
Vegan breadsticks
Toasted sourdough
Simple green salad
Roasted vegetables
Bruschetta
Garlic and herb flatbread

Storage and Reheating

Store leftover soup in an airtight container in the refrigerator for up to 4 days.

Keep in mind that the noodles will continue absorbing liquid as the soup sits, so the leftovers may become thicker.

When reheating, add a splash of vegetable broth or water and warm gently on the stovetop or in the microwave.

For freezing, it’s best to freeze the soup without the noodles, because cooked pasta can become soft after thawing. Prepare fresh noodles when reheating for the best texture.
