Chicken Cordon Bleu is one of those food situations where the whole is greater than the sum of its parts. The combination of crunchy breaded chicken, savory ham, and nutty, melted Swiss cheese is a trio so fine that it seems like those three ingredients were just meant to be together. It seems like thereβs not a thing you could do to improve upon that combinationβ¦ But what if you added the comfort of pasta? And baked it into a cozy, creamy casserole? Well, then youβd have our Chicken Cordon Bleu Tetrazzini, which has all the flavor of that classic trio but in comforting casserole form.
