While you are prepping the soup, cook the pasta according to the package directions, Drain and set aside until the end.
Fry the ground beef and onions together in the metal cooking pot in your Instant Pot using the "saute" function on your Instant Pot until the ground beef is cooked and the onions are translucent. Add in the garlic and fry until brown. Drain the fat.
To cook immediately, press the soup button, seal the Instant Pot, close the vent and cook for 4 minutes. Let it naturally release - you can manually release but for safety's sake I don't recommend it.
Temperatures and cook times may vary based on appliance type / brand. Always test with a small amount first to ensure nothing is over or undercooked.
