Cheesy Turkey & Vegetable Tetrazinni

Turkey tetrazzini is the unofficial Thanksgiving leftover champion of the American casserole canon. Cooked turkey, frozen peas and carrots, and a creamy cheese sauce get tossed with egg noodles, topped with seasoned breadcrumbs and parmesan, then baked until the cheese bubbles through and the topping crisps to gold.

The sauce comes together fast: condensed cream of mushroom soup thinned with milk and water, then bulked up with two cups of shredded cheddar. The canned soup is the unsung shortcut here. Don’t be tempted to substitute cream alone; the soup adds savory mushroom depth and the right thickening profile.

Pimientos are the colorful retro touch. Two tablespoons throughout the casserole adds little red flecks and a faint sweet-pepper note. They’re what tells you this is a tetrazzini and not just a generic noodle bake.

The breadcrumb-parmesan topping is what puts this in the dinner-rotation hall of fame. As it bakes uncovered, the crumbs crisp into a golden crust while the parmesan adds salty depth. Don’t pack the topping; sprinkle it loosely so it browns evenly.

Pro Tips

• Cook the noodles 1 to 2 minutes less than the package directs. They’ll finish cooking in the casserole and won’t turn mushy.
• Use leftover turkey from a roasted bird, not deli sliced. Real roast turkey adds significantly more flavor.
• Sharp cheddar is the right cheese choice. Mild cheddar disappears into the sauce; sharp gives you that classic tetrazzini flavor.
• Make a double batch and freeze one unbaked. Wrap tightly and freeze up to 2 months; thaw overnight in the fridge before baking.

Variations

• Stir in 1 cup of sautéed mushrooms for extra umami depth.
• Substitute leftover chicken for the turkey for a year-round version.
• Add 2 tablespoons of dry sherry to the sauce for a more sophisticated, classic tetrazzini flavor.
