Turn the Instant Pot on to Saute mode. Add in the ground beef, diced onion, and minced garlic. Cook until the beef is browned and onion translucent.
1 lb ground beef, 1 onion, diced, 3 garlic cloves, minced
Add the tomatoes, cumin, chili powder, Rotel, tomato paste, and beef broth.
10 oz can of Rotel tomatoes, 28 oz can of crushed tomatoes, 6 oz can of tomato paste, 1 tablespoon ground cumin, 2 tablespoon ground chili powder, 28 oz beef broth
Add the lid to the Instant Pot, ensuring the valve is set to Sealing Mode.
Turn the Instant Pot on by hitting the Chili/Bean button and adjust the time manually to 12 minutes. Since you have no beans in the pressure cooker, you only need 12 minutes. Allow up to 15 minutes for the pressure cooker to build up pressure before the cook countdown starts.
After the cook timer beeps, allow a natural release of 10 minutes before turning the valve to Vent. Adjust salt and pepper seasoning and stir.
Serve immediately and enjoy!
