Step 1

Stovetop Directions:Heat olive oil in a large pot over medium heat. Add sausage and brown for 3 minutes, breaking it up into bite-size pieces with a wooden spoon.

Step 3

Add onion, garlic, oregano, salt, pepper, and red pepper flakes, and cook until onion is softened and sausage is browned, about 7 more minutes.

Step 5

Stir in tomato paste and cook for 2 minutes more.

Step 7

Add diced tomatoes, bay leaves, and chicken stock. Bring just to a boil, then reduce heat and simmer for 15 minutes.

Step 9

Meanwhile, prepare pasta in a separate saucepan according to package directions, to el dente. Do not over cook. Drain.

Step 11

In a medium bowl, create the "cheesy yum" by combining the ricotta, Parmesan, salt, and pepper. Set aside.

Step 13

Stir fresh basil into soup right before serving.

Step 15

To serve, add cooked pasta to individual bowls and ladle soup over the top. Serve with dollops of cheesy yum and additional shredded mozzarella.

Step 17

Crock-Pot Directions: Heat a large nonstick skillet over medium-high heat and add oil. Once hot, add sausage and brown for 3 minutes, breaking it up into bite-size pieces with a wooden spoon. (*If you have a multi-cooker, set it to BROWN/SAUTE and add the oil. Once hot, add sausage and brown for 3 minutes, breaking it up into bite-size pieces with a wooden spoon.)

Step 19

Add onion, garlic, oregano, salt, pepper, and red pepper flakes, and cook until onion is softened and sausage is browned, about 7 more minutes.

Step 21

Stir in tomato paste and cook for 2 minutes more.

Step 23

Transfer sausage mixture to slow cooker (or just proceed if using a multi-cooker) and add diced tomatoes, bay leaves, and chicken stock. Cover and set slow cooker to low 8 hours or high 4 hours.

Step 25

In a medium bowl, create the "cheesy yum" by combining the ricotta, Parmesan, salt, and pepper. Set aside or refrigerate until ready to eat.

Step 27

About 30 minutes before soup is ready, add pasta to slow cooker. Cover and cook until pasta is just al dente, checking after 15 minutes. (If you plan to let the soup sit for awhile before serving or are planning on leftovers, I strongly recommend cooking the pasta separately to avoid mushy noodles. Read section in post titled "Can I Cook the Pasta in the Soup?" for more info.)

Step 29

Stir fresh basil into soup right before serving.

Step 31

To serve, add soup to individual bowls with dollops of cheesy yum plus additional shredded mozzarella.

Step 33

Instant Pot Directions:(Note: Instant Pot says "do not fill the inner pot more than 2/3 full", so you will need one that is a 6-quart size or larger. I use this 6-quart Instant Pot, and find it to be a great size for our family's meals.) Press SAUTE on the Instant Pot and add oil. Once hot, add sausage and onion and cook for 5 minutes, breaking it up into bite-size pieces with a wooden spoon.

Step 35

Stir in garlic, oregano, salt, pepper, and red pepper flakes, and cook until onion is softened and sausage is browned, about 3 more minutes.

Step 37

Stir in tomato paste and cook for 2 minutes more. Scrape bottom of pot very well.

Step 39

Press CANCEL to turn Instant Pot off. Stir in diced tomatoes, bay leaves, and chicken stock.

Step 41

Press SOUP and cook for 15 minutes on this setting.

Step 43

Meanwhile, create the "cheesy yum" by combining the ricotta, Parmesan, salt, and pepper in a mixing bowl. Set aside.

Step 45

Press CANCEL and quick release pressure.

Step 47

Add mafalda or fusilli pasta, submerging it below the soup broth.

Step 49

Press SOUP and cook for 8 minutes more for al dente mafalda or fusilli pasta. Thicker pastas will take a bit more time to cook. (If you plan to let the soup sit for awhile before serving or are planning on leftovers, I strongly recommend cooking the pasta separately to avoid mushy noodles. Read section in post titled "Can I Cook the Pasta in the Soup?" for more info.)

Step 51

Press CANCEL and then quick release pressure.

Step 53

Stir in fresh basil and then serve. Add soup to individual bowls with dollops of cheesy yum plus additional shredded mozzarella.
