Ingredients

For the Cheese Mixture:

  • 1 Tablespoon basil freshly chopped
  • 1 Tablespoon parsley freshly chopped
  • 1 Cup ricotta cheese
  • 1 Cup mozzarella cheese shredded
  • 1/4 Cup parmesan freshly grated
  • 1/2 Teaspoon garlic salt

Instructions

  • Heat a frying pan or skillet over medium/high heat. Add olive oil and swirl to coat.  
  • Season sausage with a pinch of salt and pepper. Brown the sausage. Drain sausage over a bowl and pour the drippings back into the pan and add sausage to the slow cooker. 
  • Next, add onions, crushed tomatoes, sun dried tomatoes, tomato paste, red pepper flakes, wine, and a pinch of salt and pepper to the hot pan. Sauté for 5 minutes then add minced garlic. Cook for 1 more minute, then pour into the slow cooker. 
  • Add vegetable broth, Italian seasoning, granulated garlic, onion powder, salt, and black pepper to the slow cooker. Cover, and set to low for 6 hours.  
  • At the 6 hour mark, break apart the lasagna noodles and add to the slow cooker to soften for 30 minutes. 
  • Add chopped kale to the slow cooker for the final 10 minutes of cooking time.  

Make the Cheese Mixture:

  • Prepare the cheese mixture. Combine ricotta, mozzarella, parmesan, basil, parsley, and garlic salt in a small bowl and mix.  
  • Serve lasagna in a bowl with a dollop of ricotta cheese and a sprinkle of parmesan cheese.

Notes

Don't skip the sear: Browning the Italian sausage and sautéing the veggies first adds color and flavor, so I don't recommend skipping these steps.
Use the right size crockpot: Use a large crockpot for this soup. If you use a too-small one, the soup won't cook evenly. If you only have a small or medium one, you can halve the soup recipe ingredients.
Use regular lasagna noodles: No-boil noodles will also work, but need much less cooking time.
