Place 1 lb ground beef in a large frying pan or skillet and set over medium heat.
Use a spatula or wooden spoon to break the beef into small crumbles as it heats.
Season the meat evenly with 1 teaspoon kosher salt and 1/2 teaspoon ground black pepper, stirring to distribute.
Continue cooking, stirring occasionally and breaking up any larger pieces, until no pink remains and the beef is browned.
Remove from heat immediately to avoid drying, then add to your spaghetti sauce and proceed with your sauce recipe.
