How to Make Vegetarian Lasagna Soup
Step 1: Heat the Olive Oil
Heat the olive oil in a large pot over medium-high heat.
Step 2: Sauté Onion
Add the diced onion along with a pinch of salt and pepper. Sauté while stirring frequently for about 3 minutes until softened.
Step 3: Add Garlic and Seasoning
Reduce heat to medium. Add the sliced garlic, Italian seasoning, and additional salt and pepper. Sauté for another minute until fragrant.
Step 4: Incorporate Tomato Paste
Add tomato paste to the pot and stir well to combine. Cook this mixture for about 2 minutes or until the paste turns brick red.
Step 5: Deglaze with Broth
Deglaze the pot by adding a splash of vegetable broth. Scrape any bits from the bottom of the pot for added flavor.
Step 6: Combine Main Ingredients
Add pesto, split lentils, crushed tomatoes, remaining vegetable broth, and sugar if desired. Stir with large pinches of salt and pepper.
Step 7: Bring to Simmer
Increase heat to medium-high. Bring the mixture to a gentle simmer while stirring occasionally so lentils do not stick to the bottom.

Step 9: Incorporate Spinach

When making Vegetarian Lasagna Soup, it’s easy to overlook some key steps. Here are common mistakes and how to avoid them.
- Skipping the seasoning: Not seasoning your soup adequately can lead to blandness. Always taste as you go and adjust with salt and pepper.
- Overcooking the pasta: Cooking the lasagna noodles for too long can make them mushy. Keep an eye on the time and ensure they’re cooked al dente.
