I made this Barefoot Contessa turkey tetrazzini recipe after Thanksgiving one year when I had a mountain of leftover turkey and didn’t want to make another sandwich so I turned to Ina’s classic cozy version and instantly fell in love with how creamy flavorful and elegant it turned out

Because I love comforting casseroles that feel indulgent but use up ingredients I already have this has become my favorite post-holiday dish and with its tender turkey rich mushroom sauce and cheesy baked top it’s always a crowd-pleaser at my table
Ingredients
- Here’s what I use for this recipe. You can always make substitutions if you prefer!
- Cooked turkey – The star of the dish using leftovers or roasted pieces
- Spaghetti – Forms the hearty pasta base that soaks up all the sauce
- Butter – Used to sauté the vegetables and add richness
- Mushrooms – Bring umami flavor and texture to the sauce
- Onion – Adds a sweet mellow base to the dish
- Garlic – Gives the sauce depth and aroma
- All-purpose flour – Helps thicken the creamy sauce
- Chicken or turkey broth – Builds the base of the white sauce
- Heavy cream – Adds richness and silky texture
- Frozen peas – A pop of color and sweetness throughout
- Parmesan cheese – For sharpness and a golden cheesy topping
- Gruyère or mozzarella – Melts beautifully into the sauce and topping
- Salt and pepper – Balances and enhances all the flavors
- Nutmeg – A classic touch that gives the sauce warmth
Tools You’ll Need
- Large pot – To boil the pasta
- Skillet or sauté pan – For building the creamy sauce
- Whisk – Ensures a smooth lump-free sauce
- 9×13 baking dish – Ideal for layering and baking everything together
- Mixing bowls – To toss the pasta with sauce and assemble the casserole
- Cheese grater – Freshly grated cheese melts more smoothly
- Oven mitts – For handling the hot dish safely

Instructions
Step 1:
I preheat the oven to 375°F and lightly butter a 9×13 baking dish
Step 2:
I cook 12 oz of spaghetti in salted boiling water until just al dente then drain and set it aside
Step 3:
In a large skillet I melt 4 tablespoons of butter and sauté 1 diced onion and 8 oz of sliced mushrooms over medium heat until soft then stir in 2 cloves of minced garlic and cook for 1 minute
Step 4:
I sprinkle in 1/4 cup of all-purpose flour and whisk it constantly for 2 minutes to create a roux
Step 5:
I slowly whisk in 2 cups of chicken or turkey broth and 1 cup of heavy cream then season with salt pepper and a pinch of nutmeg and simmer until thickened about 5 minutes
Step 6:
In a large bowl I combine the cooked spaghetti 3 cups of shredded or chopped turkey 1 cup of frozen peas 1/2 cup grated Parmesan and 1 cup shredded Gruyère or mozzarella then pour the sauce over and toss to coat evenly
Step 7:
I transfer everything to the prepared baking dish and top with an extra sprinkle of Parmesan and Gruyère
Step 8:
I bake uncovered for 25 to 30 minutes until bubbly and golden then let it rest for 10 minutes before serving
Tips
If you don’t have Gruyère you can use Swiss or mozzarella for a melty finish
A dash of white wine in the sauce adds a touch of acidity and depth
Make it ahead and refrigerate overnight then bake when ready to serve
