Step‑by‑Step Instructions for Vegan Lasagna Soup
Step 1: Sauté the Vegetables
In a large Dutch oven, heat 2 tablespoons of olive oil over medium heat. Add diced onion, chopped carrots, and celery, sautéing for about 5 minutes until they soften and become aromatic. Stir occasionally, allowing the vegetables to mingle and release their flavors, preparing a hearty base for your Vegan Lasagna Soup.
Step 2: Add Aromatics
Stir in 3 cloves of minced garlic along with 1 teaspoon each of dried oregano and basil. Cook for an additional minute, stirring continuously until the garlic becomes fragrant and begins to slightly brown. This step infuses the soup with warm, inviting Italian aromas, and enhances the overall flavor profile of the Vegan Lasagna Soup.
Step 3: Incorporate Tomato Paste
Next, add 2 tablespoons of tomato paste to the pot and cook for about 1 minute, stirring to combine. This helps to caramelize the tomato paste, intensifying its sweetness before adding other ingredients. The color will darken slightly, signaling that it’s ready to meld with the remaining components.
Step 4: Add Main Ingredients
Pour in a 28-ounce can of chopped tomatoes, 1 diced courgette, and 1 cup of green lentils, followed by 6 cups of vegetable stock. Bring the mixture to a rolling boil, then reduce the heat to low and let it simmer gently for 5 minutes. This allows the lentils to start cooking, enriching the soup’s texture while infusing it with robust flavors.
Step 5: Mix in Lasagna Sheets
Break 8 lasagna sheets into pieces and add them to your simmering soup. Stir well and allow it to continue cooking for about 10 minutes. Keep an eye on the pasta, checking for doneness; it should be al dente. If the soup thickens too much, add additional vegetable stock to reach your desired texture.
Step 6: Finish with Spinach
Stir in 4 cups of fresh baby spinach and allow it to wilt for about 2 minutes. This not only adds a vibrant green color to your Vegan Lasagna Soup but also packs in essential nutrients. Taste and adjust the seasoning with salt and pepper, ensuring every bite is flavorful.
Step 7: Serve and Enjoy
Ladle the Vegan Lasagna Soup into bowls and consider topping each serving with nutritional yeast or vegan cheese for added flavor. Enjoy warm, savoring the rich combination of veggies and pasta, all reminiscent of a comforting lasagna in a delightful soup form!
