Ingredients & Substitutions
This Vegan Lasagna Soup uses simple, wholesome ingredients that are easy to find at your local grocery store or even in your pantry. Each ingredient plays a key role in building the hearty and comforting flavors of this dish:
Vegan Italian Sausages:
These sausages are perfect for adding a savory, meaty texture and a boost of flavor to the soup. If you’re looking for a healthier option or prefer a gluten-free version, swap them with brown or green lentils. These lentils provide a natural, earthy taste and are packed with plant-based protein, making the soup even more nutritious.
Cremini Mushrooms:
Known for their rich, umami flavor, these mushrooms add depth to the dish. If mushrooms aren’t your favorite, you can leave them out or substitute them with white beans, green lentils, or even crumbled tofu for extra texture.
Yellow Onion:
A foundational ingredient that infuses the soup with a natural sweetness as it cooks. If you’re out of yellow onions, you can use red onion or shallots for a slightly sharper flavor.
Garlic:
Freshly minced garlic is a must for creating layers of flavor in this soup. Its aromatic profile ties all the other ingredients together. For convenience, pre-minced garlic or garlic paste can be used, but fresh garlic is unbeatable!
Italian Seasoning Blend:
This classic mix of dried herbs like basil, oregano, thyme, and rosemary provides the signature Italian flavor that makes this soup so comforting. If you don’t have a ready-made blend, you can easily create your own using pantry staples.
Tomato Paste:
A small but mighty ingredient, tomato paste intensifies the rich tomato flavor of the soup. It’s essential for that deep, robust taste, so don’t skip it!
Marinara Sauce:
This serves as the tomato base of the soup. You can use a jarred marinara for convenience or prepare a homemade version for a personal touch. Look for a sauce with minimal added sugar and high-quality ingredients for the best results.
Vegetable Broth:
The liquid backbone of the soup, vegetable broth enhances the overall flavor while keeping the dish plant-based. For an extra savory kick, try using a chickenless broth or add a splash of soy sauce for added depth.
Lasagna Noodles:
The star of the show! These broken lasagna sheets mimic the texture and feel of classic lasagna in soup form. For dietary needs, substitute with gluten-free noodles, campanelle pasta, or even another pasta shape of your choice.
Cashew Cream:
This creamy addition brings richness to the soup without the need for dairy. You can make it at home by blending soaked cashews with water and a touch of lemon juice. Alternatively, use coconut milk, soy cream, or tofu ricotta for a creamy texture with subtle flavor differences.
Baby Spinach:
Adding fresh spinach not only boosts the nutritional value but also provides a pop of vibrant green color. If fresh spinach isn’t available, frozen spinach works just as well—just be sure to thaw and drain it before adding.
Vegan Mozzarella:
A finishing touch that melts beautifully into the soup, creating gooey, cheesy perfection. If you’re looking for alternatives, try vegan ricotta cheese or sprinkle a bit of nutritional yeast for a cheesy flavor without the melt.
Seasonings:
Salt, black pepper, and red chili flakes are essential to balance and enhance the flavor of the soup. Adjust these seasonings to your taste preferences. For a smoky twist, you could even add a pinch of smoked paprika.
With these versatile ingredients, this recipe ensures a comforting and delicious soup that’s easily adaptable to different dietary needs or personal tastes. Whether you want a protein-packed meal with lentils or a creamy soup using coconut milk, there’s plenty of room to customize this dish!
