Mince the onion and melt the butter in a skillet over medium heat.
Add the minced onion and sauté until soft and translucent.
Add the ground beef to the skillet.
Brown the beef thoroughly, breaking it apart with a spoon for an even texture.
Stir in the chili powder, paprika, tomato sauce, ketchup, mustard, and Worcestershire sauce.
Make sure everything is well combined for rich flavor distribution.
Pour in the water and reduce heat to a simmer.
Allow it to cook for around 30 minutes, stirring occasionally to prevent sticking.
Once the chili has thickened and flavors have melded, remove it from heat.
Serve over hot dogs or as desired.
