Who needs pasta when you can enjoy all that deliciousness in a bowl? It’s like a warm hug on a chilly day! I love making a big pot and then enjoying leftovers for lunch—so easy and satisfying!
Key Ingredients & Substitutions
Ground Beef or Italian Sausage: Both work great for this soup. If you want a leaner option, turkey or chicken sausage is an excellent alternative. You could also use plant-based meat substitutes for a vegetarian version!
Tomato Products: Crushed tomatoes and tomato sauce form the base of the soup. If you’re looking to lower acidity, choose low-sodium or organic options. You can also use fresh tomatoes—just blend them if you prefer a smoother soup.
Cheese: Ricotta adds creaminess, but you can substitute cream cheese or cottage cheese if you prefer. For the mozzarella, low-fat cheese can work as well, though I love the classic meltiness of full-fat mozzarella!
Broth: Beef or chicken broth adds depth. Vegetable broth is a great vegetarian alternative, but be sure to check for low-sodium options if that’s your preference.
How Do I Make the Perfect Broth for This Soup?
The broth is key to rich flavor in your Lasagna Soup. First off, don’t skip browning the meat—it adds a lovely depth! After adding the tomatoes and broth, let it simmer low and slow. This step helps all the spices meld together, creating a delicious and aromatic soup.
- Sauté the onion and garlic until soft; this builds the base flavor.
- After adding the tomatoes and broth, allow the soup to come to a gentle boil for a robust flavor.
- Simmer for at least 20 minutes to let all the ingredients blend well.
- Taste before serving to adjust seasoning—it’s the final touch that can elevate your soup!
Enjoy crafting this comforting low-carb lasagna soup, perfect for any day of the week!
