Coat the bottom of a 6-quart Instant pot with butter. Add the ground beef, onion, and garlic and press Sauté. Cook while crumbling the meat for 5 minutes or until beef is almost cooked through. Press Cancel to stop the Sauté. Drain the excess grease. Stir in all remaining ingredients. Seal the lid, press Pressure Cook or Manual, and set the timer for 5 minutes. Once finished, let the pressure release naturally. Remove the lid and stir well before serving.

Place the ground beef, onion, and garlic in a 6-quart slow cooker. Stir in all of the remaining ingredients. Cover and cook on High for 3 hours or on Low for 6 hours, until the beef is cooked through. Stir about 1 hour into cooking to crumble the beef.

For a super low carb meal, spoon into butter lettuce leaves, top with sliced red onion and cheddar cheese, and serve. For a traditional Sloppy Joe sandwich, serve on a sandwich roll or hamburger bun, topped with sliced red onion and cheddar cheese.
