Lasagna Soup
with lentils / ricotta / mushrooms / spinach

Active: 40 min Total: 40 min
We created this flavorful soup in 2018 to fill a weeknight craving for lasagna with far less work. The soup even includes lasagna noodles (broken into pieces) and a topping of ricotta cheese to give you the same flavors as the original.
Smarts: This soup is great for making ahead / freezing, but wait to add the noodles until right before serving.

  • Garlic - 4 cloves , chopped
  • Lasagna noodles - 6 oz , broken into pieces

  1. Heat a Dutch oven with oil over medium heat. Stir in onions, garlic, and mushrooms and cook for 2 to 3 minutes.
  2. Stir in tomato paste, oregano, basil, Italian seasoning, and red pepper flakes and saute until fragrant, ~1 minute more.
  3. Pour stock and tomatoes (including liquid) over mushrooms and aromatics. Add bay leaves. Bring to a simmer.
  4. Stir lasagna noodles into soup and cover.
  5. Simmer soup just until lasagna noodles are al dente, tender but still with some bite. This should take 10 to 15 minutes, but watch closely to prevent over-cooking the noodles. In the last minute of cooking, stir in lentils and spinach leaves.
  6. Remove bay leaves. Taste soup and season with some salt and pepper.
  7. Divide soup between serving bowls. Top each bowl with a spoonful of ricotta cheese and some Parmesan cheese (if using). Enjoy!
