Step 1: Prepare the Noodles
Boil the broken lasagna noodles according to package directions until al dente. This ensures they don’t overcook and become mushy in the soup. Drain and set aside.
Step 2: Brown the Beef
In a large Dutch oven, cook the ground beef over medium-high heat until it’s browned and no longer pink, breaking it into small pieces as it cooks for an evenly distributed texture throughout your soup.
Step 3: Add Aromatics
Add the minced garlic to the browned beef, stirring constantly for about a minute until fragrant. Be careful not to burn the garlic or it will turn bitter.
Step 4: Build the Base
Pour in the diced tomatoes with their liquid, allowing them to simmer with the beef and garlic for about two minutes to meld the flavors.
Step 5: Simmer the Soup
Stir in the marinara sauce and beef broth, then add the Italian seasoning. Allow the mixture to simmer gently to blend the herbal and tomato flavors together.
Step 6: Incorporate the Pasta
Stir in the drained cooked pasta, ensuring it’s evenly coated in the soup base. Let the soup simmer another five minutes, allowing the pasta to absorb the flavors.
Step 7: Finish with Cheese
About five minutes before serving, spoon in the ricotta cheese and sprinkle the shredded Italian blend cheese on top. Cover the pot for about 3-5 minutes until the cheese on top has melted and become gooey.
