Gather all ingredients.
Place cabbage, tomatoes with juice, onion (if using), seasoning, and salt into Instant Pot on Saute for low heat; cook and stir until it begins to simmer.
Change to Meat/Stew setting on medium. Add lean ground beef on top; cover and cook for 30-40 minutes. Use quick release at the end of the timer. Can be set back to saute to finish if the beef is undercooked.
Serve and enjoy!
