Beefy, oniony, cheesy, and oh so so good! This casserole will fill you up and it won’t slow you down. Make with egg noodles or you could even substitute for rice. Just make sure everyone comes to the table with a big appetite because they are going to want seconds…….. maybe even thirds!

You can use Gruyere cheese, but that gets a little spendy….. I use swiss cheese for a perfect substitute. Swiss doesn’t set me back $10 a pound!
