Set the Instant Pot to the sauté setting and add the ground beef. Cook the beef until browned, using a spatula to break the meat into crumbles while cooking.
Add the crushed tomatoes, tomato sauce, chili seasoning, garlic salt, onion, kidney beans and beef broth to the Instant Pot.
Stir all the ingredients together until well combined.
Seal the Instant Pot lid and cook on high pressure for 15 minutes.
Carefully perform a quick release once the cooking time is complete.
Serve the chili hot topped with shredded cheddar cheese and sour cream. Enjoy!
