Classic Chicken Tetrazzini is outrageously creamy and topped with lots of cheese and sliced almonds. There is so much flavor in this tetrazzini. It is pure old-fashioned comfort food. Mushrooms, bell pepper, onion, and diced pimentos add flavor and a little color.
Half-and-half and a can of condensed cream of mushroom soup make for a really creamy and rich base to this casserole. If you are looking for a recipe without condensed soup, try this Turkey Tetrazzini. You can easily use chicken instead or turkey.
With both parmesan cheese and a full two cups of shredded cheddar cheese, this chicken casserole is extra cheesy.
Classic Chicken Tetrazzini Recipe Tips
The pimentos can be left out if you wish. As can the mushrooms if you don’t like them.
The dry sherry adds additional flavor but it can be left out without sacrificing too much flavor if you don’t have a bottle. Be sure to use dry sherry, not regular sherry which has a sweet flavor. A bottle from the liquor store doesn’t cost much and will keep a good long while in your refrigerator once opened.
