Chicken Tetrazinni

Chicken tetrazzini is the all-American casserole named for opera singer Luisa Tetrazzini, supposedly created for her at a San Francisco hotel in the early 1900s. The dish has evolved from its restaurant origins into a beloved home-cooking standard: poached chicken breast and spaghetti baked under a creamy mushroom and sherry sauce, topped with a generous layer of melted cheddar. It’s the dinner that fills bellies and freezes for later.

Poaching the chicken in seasoned water rather than roasting or pan-frying produces the most tender, juicy meat. The recipe’s instruction to cool the chicken in the broth is the chef’s secret. As the chicken cools in its cooking liquid, it stays moist and absorbs additional flavor. This step is what separates dry, stringy tetrazzini from the version everyone wants seconds of.

The sherry is non-negotiable. Cooking sherry adds the depth and slight sweetness that defines classic tetrazzini. Substituting white wine works but gives a different flavor; skipping it entirely produces a flatter, less interesting dish. A half cup might seem like a lot, but it cooks down to perfection in the bake.

The two cheese layers (cheese in the sauce, more cheese on top) is the proper finish. The first cheese melts into the sauce as it bakes, while the second creates the signature golden-bubbly top that defines casserole crust nostalgia.

Pro Tips

• Use rotisserie chicken to save 30 minutes if pressed for time. Pull 3 to 4 cups of meat.
• Cook the spaghetti al dente. It continues cooking in the casserole and finishes perfectly with a slight bite.
• Make ahead: assemble fully, cover and refrigerate up to 24 hours before baking. Add 10 minutes to bake time.
• Freezes beautifully unbaked or baked. Wrap tightly; reheat covered until heated through.

Variations

• Add 1 cup of sauteed fresh mushrooms for double mushroom flavor.
• Stir in ½ cup of frozen peas to the casserole before baking for color.
• Use a mix of cheddar and parmesan or Gruyere for more sophisticated cheese flavor.
• Top with breadcrumbs tossed with melted butter in the last 5 minutes for an extra-crunchy top.
