I've been making this basic recipe for years. I also cook the macaroni separately from the hamburger and then combine everything once it's cooked. My son calls this "McOnion Burger" because I add french fried onions. I also add a can of cream of mushroom or chicken soup, half a can of milk and extra cheddar cheese. No catsup. Add half a can of french fried onions to the mix, pour it all in a casserole dish, top with more shredded cheese and the other half of the onions and bake at 350 for 10-15 mins or until cheese is melted and onions browned.
