Saute diced onion in a large pan over medium heat with 1 Tablespoon of olive oil.
After 3 minutes add beef to pan and break apart with a wooden spoon. Cook beef until brown on all sides (about 10 minutes).
Once the beef is brown, add in the ketchup, water, garlic powder, brown sugar, salt, pepper, and Worcestershire sauce. Mix well and simmer for 15 minutes slightly covered with a lid.
Serve on top of buns. Enjoy!
Notes
Recipe makes 4 large Sloppy Joes or 6 decent sized portions.
Draining beef fat is optional.
If sauce gets too dry during the simmering process, just add a few more ounces of water to pan and stir to combine.
