Chicken Tetrazzini with Cheddar & Pimentos

Named after an Italian opera singer, this one-dish diva features chicken, Cheddar, and a sherry-cream sauce. It’s sure to inspire requests for an encore performance.

When it comes to tetrazzini, there are some things you can always count on — spaghetti, almonds, and a creamy sauce are all common components of the casserole favorite. Made with any type of protein from chicken to seafood, tetrazzini is an ideal dish to modify, depending on your personal tastes. Everything from the cheese to the nuts can be substituted, in favor of other options.

In this version, sharp Cheddar joins the more traditional Parmesan for an extra cheesy bite. And pimentos deliver bursts of sweetness that really amp up the pepper flavor.

Boil the spaghetti before adding it to the casserole, so it can fully absorb the sauce. And cook the rest of the ingredients in one large saucepan, then transfer them to a baking dish, for a fully incorporated, flavorful meal!
