Brown the ground beef in a skillet over medium heat, then drain any grease.
Pour the pasta sauce into the bottom of the slow cooker, then add the ground beef.
Pour in the water, then sprinkle the seasonings on top.
Lay the spaghetti noodles on top (you may have to break them in half to get them to fit), then lightly press them down into the liquid until they are fully submerged.
Cover and cook on low for 1.5 to 2.5 hours, stirring occasionally to keep the noodles from sticking to each other and to check for doneness.

Use regular spaghetti noodles only — thin spaghetti will overcook and become mushy.
Stir occasionally during cooking to prevent noodles from sticking together.
Cooking time may vary by slow cooker; begin checking for doneness at 1½ hours.
If the pasta absorbs too much liquid, stir in a splash of broth or water before serving.
Ground beef can be substituted with Italian sausage or ground turkey if desired.
