Ingredients

  • 12 oz spaghetti or thin spaghetti, broken in half
  • 3 cups cooked turkey, shredded or cubed
  • 6 tbsp unsalted butter
  • 1 yellow onion, diced
  • 2 celery stalks, thinly sliced
  • 8 oz cremini mushrooms, sliced
  • 3 garlic cloves, minced
  • 6 tbsp all-purpose flour
  • 2 cups chicken or turkey broth
  • 1 cup heavy cream
  • 1/4 cup dry sherry (or substitute chicken broth)
  • 1 cup frozen peas
  • 1 tsp salt
  • 1/2 tsp black pepper, freshly ground
  • 1/2 cup Parmesan cheese, grated
  • 1/2 cup panko breadcrumbs

Instructions

  1. 1

    Preheat oven to 375 F (190 C) and grease a 9x13-inch baking dish. Cook 12 oz broken in half spaghetti or thin spaghetti in salted boiling water until barely al dente, 1-2 minutes less than package directions. Drain and set aside.

  2. 2

    In a large deep skillet, melt 6 tbsp unsalted butter over medium-high heat. Add 1 diced yellow onion and 2 thinly sliced celery stalks and cook until softened, about 4 minutes. Add 8 oz sliced cremini mushrooms and cook, stirring, until they release their liquid and turn golden, about 5 minutes. Add 3 minced garlic cloves and cook 30 seconds.

  3. 3

    Sprinkle 6 tbsp all-purpose flour over the vegetables and stir for 1-2 minutes until the raw flour smell is gone. Gradually whisk in 2 cups chicken or turkey broth, then 1 cup heavy cream and 1/4 cup dry sherry (or substitute chicken broth), until smooth.

  4. 4

    Bring to a simmer and cook, stirring, until the sauce is thick enough to coat the back of a spoon, about 4 minutes. Season with 1 tsp salt and 1/2 tsp freshly ground black pepper.

  5. 5

    Remove from heat. Stir in the drained spaghetti or thin spaghetti, 3 cups shredded or cubed cooked turkey, and 1 cup frozen peas until everything is evenly coated. Transfer to the prepared baking dish.

  6. 6

    In a small bowl, toss 1/2 cup panko breadcrumbs with 1/2 cup grated Parmesan cheese and scatter evenly over the top of the casserole.

  7. 7

    Bake uncovered until the topping is golden and the casserole is bubbling, 25-30 minutes. Let rest 10 minutes before serving.

Questions

What is Turkey Tetrazzini?

A creamy baked pasta casserole loaded with shredded turkey, tender mushrooms, and spaghetti, all bound in a rich sherry-cream sauce and topped with a Parmesan-breadcrumb crust. The ideal way to transform leftover turkey into a crowd-pleasing dinner. This reference files it under American dinner: made on the stovetop and in the oven, rated medium and about 70 minutes start to finish.

What oven temperature does Turkey Tetrazzini need?

For Turkey Tetrazzini, the oven is set to 375 F (about 190 C) in step 1. The longest stretch at that heat is 30 minutes, in step 7.

How do I know when Turkey Tetrazzini is done?

Go by the cues in the method rather than the clock. Step 5: cook until everything is evenly coated. Step 7: cook until the topping is golden and the casserole is bubbling.

Why rest the meat in Turkey Tetrazzini?

Step 7 reads: "Let rest 10 minutes before serving." Heat drives the juices toward the center. The rest in step 7 lets them spread back out, so they stay in the meat instead of running onto the board when you cut.

What can I use instead of panko in Turkey Tetrazzini?

The entry for Turkey Tetrazzini calls for 1/2 cup panko breadcrumbs. In its place: Coarse dry breadcrumbs, crushed cornflakes or crushed crackers all work. Fine breadcrumbs coat more densely, so use a little less.

Can I make Turkey Tetrazzini ahead?

Yes, it takes well to being made ahead. Refrigerate what is left of Turkey Tetrazzini within two hours and eat it within three days. Reheat covered in a 300 F oven until warmed through. The pasta keeps drinking the sauce as it sits; loosen it with a splash of water or stock.
