My Mother-in-law has made this for her children, grandchildren and great-grandchildren for years. When I married my husband, I would hear them all speak of this. I nearly fell out when I got the non-recipe, recipe from her. It really is good with a nice salad and hot crusty bread.
Boil the pasta and drain, reserve pasta until needed. Brown the ground chuck (I season while cooking with salt, pepper and dash of garlic powder). Drain the meat once cooked through to remove animal fat. Return meat to pan, add the cooked pasta and enough ketchup to coat well and make a sauce (its a pretty good bit for my taste). Turn the heat down to med-low and simmer until ketchup begins to darken. (When heated it will take on a deeper brownish color). If it becomes too dry, add a splash of water (or pasta water) and continue simmering. I usually simmer about an hour, the longer the better.
**NOTE** as I stated earlier, this is a non-recipe, recipe. The amounts can easily be adjusted to please a pasta lover vs. a meat lover. To create a more sophisticated dish, fresh herbs, fresh garlic, diced onion, diced bell pepper could be added to the simmering meat as it cooks. Make it your own, add whatever your family loves! But do try this, it really is good!!!
