Heat a 4.5-quart soup pot over medium-high heat. Add the olive oil and heat until shimmering.
Add the ground beef, onions, and garlic. Sauté until the beef is cooked through, stirring as needed. Drain excess fat if necessary.
Stir in the diced tomatoes (with their juice), tomato sauce, tomato paste, chicken broth, Italian seasoning, salt, pepper, and uncooked pasta.
Increase the heat to high and bring the soup to a boil.
Reduce the heat to medium and simmer for 10-15 minutes, stirring frequently to prevent the pasta from sticking together, until the pasta is cooked to your liking.
Adjust the soup's consistency by adding more water or broth, if needed.
Serve with toppings of your choice: either stir the ricotta, mozzarella, and Parmesan into the entire soup or serve them on the side for individual servings. Garnish with fresh parsley.
Storage Instructions
Allow the soup to cool completely before refrigerating in an airtight container for up to 5 days.
For freezing, store in a freezer-safe container for up to 90 days (or longer if vacuum sealed).
Reheating Instructions
When reheating, add small amounts of water or broth as needed to adjust the consistency, as the noodles will absorb some of the broth during storage.
Notes
Use sturdy pasta like bowtie, macaroni, rigatoni, or penne, as lasagna noodles tend to break apart by the second or third day.
Substitute ground beef with ground turkey or Italian sausage for a different flavor.
For a thicker broth, you can use canned crushed tomatoes instead of diced tomatoes.
If you don’t have canned tomato products on hand, replace them with a 24-ounce jar of marinara sauce and 1 cup of water.
Pressure Cooker Instructions
Select "Sauté" mode and heat olive oil in the pressure cooker.
Add the ground beef, onions, and garlic; sauté until cooked through. Drain excess fat, then deglaze the pot with a splash of broth. Press "Cancel."
Stir in the diced tomatoes, tomato sauce, tomato paste, broth, Italian seasoning, salt, pepper, and pasta.
Secure the lid and set the valve to "Sealing." Pressure cook on high for 1 minute. For al dente pasta, perform a quick release. For softer pasta, allow natural release for 10 minutes before opening the lid.
Stir the soup and adjust the consistency with additional water or broth, if needed. Follow the serving instructions above.
