This hamburger and macaroni dish is one of my mother’s recipes that has been served in our house at least once a month for the last 45 years. We even have a special name for it—HMO (Hamburger Macaroni Onions). I’ve also heard it called “goulash” or “American chop suey” or “Hamburger Noodle Casserole.” My father gets a song in his voice when he announces that we’re having HMO for dinner. You brown the meat and make the sauce while the water is coming to a boil and the macaroni is cooking. So it takes less than half an hour to make. So easy! Some of our readers know it as hamburger hotdish, mulligan, or Johnny Marzetti. Whatever it’s called, it’s comforting and so simple you’ll never think about buying a pre-mixed box of pasta and spices to “help” you make hamburger and macaroni again.

Make This Vegetarian/Vegan

Make it meat-free by adding vegetarian meat crumbles and using vegan Worcestershire sauce (many Worcestershire sauces are made with anchovies).
