Turkey tetrazzini

This recipe fits a 2-quart baking dish. For 4 servings, use a 9-by-13-inch dish and keep the oven at 375 F, but expect the bake time to stay close to the same and watch for bubbling at the edges. Do not thin the sauce much when scaling up, or the casserole can bake dry.

Ingredients
For 2 people
- 8 oz spaghetti, dry
- 8 oz ground turkey
- 1 tbsp olive oil
- 4 oz cremini mushrooms, sliced
- 3 oz yellow onion, finely chopped
- 1 tsp minced garlic
- 2 tbsp unsalted butter
- 2 tbsp all-purpose flour
- 1 1/4 cups low-sodium chicken broth
- 1/2 cup whole milk
- 1/4 cup heavy cream
- 2 tbsp dry sherry
- 1/2 tsp kosher salt
- 1/4 tsp black pepper
- 1/8 tsp ground nutmeg
- 1 tsp Worcestershire sauce
- 1/2 cup frozen peas
- 1/2 cup grated Parmesan cheese
- 1 tbsp chopped parsley
- 1/4 cup plain breadcrumbs
- 1 tbsp melted unsalted butter
Method
- Cook the pasta and prep the ovenHeat the oven to 375 F. Bring a large pot of salted water to a boil and cook the spaghetti until just shy of al dente, about 1 minute less than the package timing. Drain, then reserve 1/2 cup of the cooking water in case the sauce needs loosening later. Lightly grease a 2-quart baking dish.
- Brown the turkeySet a 10- or 12-inch skillet over medium-high heat and add the olive oil. Add the ground turkey and cook, breaking it up with a spatula, until no pink remains and the meat has taken on some light browning, 6 to 8 minutes. If there is a lot of liquid, keep cooking until it evaporates. Transfer the turkey to a plate.
- Build the mushroom baseLower the heat to medium and add the butter to the same skillet. Stir in the mushrooms, onion, and 1/4 teaspoon of the salt, and cook until the mushrooms have released their moisture and the onion is soft and lightly golden, about 6 minutes. Add the garlic and cook 30 seconds, just until fragrant. Pour in the sherry and scrape up any browned bits from the pan; simmer 1 minute.
- Make the creamy sauceSprinkle the flour over the vegetables and stir for 1 minute so it loses the raw flour taste. Slowly whisk in the chicken broth, then the milk and cream, making sure the sauce is smooth. Stir in the remaining 1/4 teaspoon salt, black pepper, nutmeg, and Worcestershire sauce. Simmer gently for 3 to 5 minutes, stirring often, until the sauce lightly coats a spoon. If it looks too thick, whisk in a splash of the reserved pasta water.
- Combine with pasta and turkeyStir the browned turkey, drained spaghetti, frozen peas, half of the Parmesan, and the parsley into the skillet. Toss until the noodles are evenly coated and the peas are distributed. The mixture should look creamy but not watery. If it seems stiff, add a few tablespoons of reserved pasta water; if it looks loose, simmer 1 minute longer.
- Top and bakeTransfer the mixture to the prepared baking dish. Mix the breadcrumbs with the melted butter and the remaining Parmesan, then sprinkle evenly over the top. Bake uncovered for 18 to 22 minutes, until the edges are bubbling and the topping is golden brown. If the top browns too quickly, tent loosely with foil for the last few minutes.
- Rest and serveLet the tetrazzini rest for 10 minutes so the sauce settles and portions hold together. Spoon into bowls or onto plates, making sure each serving gets pasta, turkey, mushrooms, and some of the crisp topping. Serve hot from the baking dish.
Before you cook
What to get ready
The recipe's baking dish, saucepan or skillet for the filling, oven mitts and thermometer.
This version uses ground turkey; brown it separately and undercook pasta slightly before baking.
If something needs adjusting
Baked pasta is dry
Keep the sauce loose enough to coat every strand and cover if the top colors too early.
A larger batch heats unevenly
Use a second shallow dish rather than making a much deeper casserole. Check the center, not only the bubbling edges, before serving.
Store for later
Portion the cooked casserole into shallow containers for prompt chilling. Reheat the center to 165°F, covering if the topping browns too soon.
Refrigerate perishables within 2 hours, or 1 hour above 90°F. Keep the fridge at 40°F or below; use refrigerated leftovers within 3–4 days. USDA storage and reheating guidance.

Tips, swaps and questions
A little kitchen know-how
For the creamiest result, keep the sauce at a gentle simmer after adding the dairy. A hard boil can make it look grainy or separate, especially after baking. If you want a richer finish, use freshly grated Parmesan and let the casserole rest the full 10 minutes before serving so the sauce thickens around the pasta.
Make it work for you
If you do not have sherry, use dry white wine for a similar savory note, or replace it with an equal amount of broth and 1 teaspoon extra Parmesan for a milder casserole. If you prefer a lighter version, use half-and-half instead of heavy cream, but reduce the simmer slightly because it thickens more slowly.
Use more of your yellow onion and whole milk in carrot gratin.
Can I make turkey tetrazzini ahead of time?
Yes. Assemble the casserole up to the breadcrumb topping, cover, and refrigerate for up to 24 hours. Add the buttery crumbs just before baking so they stay crisp. Bake chilled casserole until hot in the center and bubbling at the edges, adding a few extra minutes if needed. Refrigerate leftovers within 2 hours and reheat to 165 F.
