Step‑by‑Step Instructions for Vegan Lasagna Soup
Step 1: Sauté Vegetables
Heat 2 tablespoons of olive oil in a large Dutch oven over medium heat. Once shimmering, add 1 diced onion, 1 diced carrot, and 1 diced celery stalk. Sauté for about 5 minutes, stirring occasionally, until the vegetables become tender and fragrant. This creates a robust base for your Vegan Lasagna Soup.
Step 2: Add Aromatics
Stir in 3 minced garlic cloves, 1 teaspoon of dried oregano, and 1 teaspoon of dried basil. Cook for an additional 1 minute, allowing the spices to bloom and release their aromatic scents. The kitchen will soon be filled with delightful Italian scents, signaling it’s time for the next step.
Step 3: Incorporate Tomato Base
Mix in 2 tablespoons of tomato paste and cook for 1 more minute, stirring constantly. This step deepens the flavor of your Vegan Lasagna Soup, creating a rich background. You’ll know it’s ready when the paste darkens slightly and becomes aromatic.
Step 4: Combine Soup Ingredients
Pour in one can (14.5 ounces) of chopped tomatoes, 1 diced courgette (zucchini), and 1 cup of green lentils along with 4 cups of vegetable broth. Increase the heat to bring everything to a boil, then reduce to a simmer. Cook for 5 minutes, until the lentils begin to soften and the flavors meld beautifully.
Step 5: Cook Pasta
Break 3 lasagna sheets into pieces and add them to the bubbling soup. Cook for about 10 minutes, stirring occasionally, until the pasta reaches al dente perfection. If the soup becomes too thick, feel free to add additional vegetable broth to adjust the consistency, ensuring a delightful bowl of Vegan Lasagna Soup.
Step 6: Finish Soup
Finally, stir in 2 cups of baby spinach until just wilted, which takes about 1-2 minutes. Season your Vegan Lasagna Soup with salt and pepper to taste. Once all ingredients are combined and heated through, your delicious and comforting soup is ready to be served hot.

Vegan Lasagna Soup Recipe FAQs
How do I choose the best vegetables for my Vegan Lasagna Soup?
Absolutely! Look for fresh vegetables that are vibrant in color, with no dark spots or signs of wilting. For carrots, choose firm ones with an even color, and for zucchini, select ones that are medium-sized with smooth skin.
How should I store leftover Vegan Lasagna Soup?
Great question! Store your soup in an airtight container in the refrigerator for up to 3 days. When ready to enjoy, you can easily reheat it on the stove or in the microwave until warmed through. Just be sure to check the consistency, as it may thicken, and a splash of vegetable broth can help return it to soup-like texture!
Can I freeze Vegan Lasagna Soup?
Very! To freeze, allow the soup to cool completely. Then transfer it to an airtight container or freezer-safe bag, making sure to leave some space for expansion. It will keep well for up to 3 months. When you’re ready to enjoy it, thaw it overnight in the fridge and reheat gently.
What should I do if my lentils are cooking too quickly?
No worries! If your lentils seem to be cooking faster than expected, reduce the heat to a low simmer to control the cooking pace. Remember, uncooked lentils will take about 15-20 minutes to become tender, so check them frequently after about 10 minutes.
Is this recipe suitable for someone with gluten allergies?
Absolutely! Just swap the lasagna sheets for gluten-free pasta. There are several great options available, like gluten-free lasagna sheets or other short pasta shapes that mimic the texture beautifully while keeping it safe for gluten-free diets.
Can I use other protein sources instead of lentils?
Yes! I often recommend chickpeas as a fantastic substitute. They add a delicious creaminess and protein-rich boost. You can also try beans like kidney or black beans for extra flavor and nourishment. Just make sure they’re cooked or canned for convenience!
