Ingredient savvy
I purchased cremini mushrooms for this recipe while they were on sale, but I knew I wouldn't be using them immediately.
Since I didn't want them to spoil before I had a chance to use them, I sautéed the mushrooms first and then stored them in the freezer. It's a smart way to take advantage of sale prices and extend the life and flavor of fresh mushrooms. Try it sometime!
The broth I used for this recipe is homemade turkey stock I'd made after making the Brown Bag Roast Turkey recipe. It's flavorful and delicious, but if you use store-bought chicken broth or stock, they will work well too. No worries.
I like to use the best Parmesan cheese I can afford for the most cheese flavor but without having to use excessive amounts. For that reason, I prefer using Parmigiano-Reggiano.
A little of this excellent cheese goes a long way, and it can also be kept in the freezer and then grated fresh for the best flavor you won't get from any other Parmesan cheese.
The easy instructions:
Sauté chopped onion in olive oil over medium/high heat.
Add the chopped celery to the skillet.
And three cups of leftover turkey, cut into bite-sized pieces.
Stir in the mushrooms (cooked or raw), and 2 cloves of minced garlic.
Season with salt, pepper, and the poultry seasoning. Stir well to combine.
Remove the turkey and mushroom to a bowl and keep warm.
In the same skillet make a roux by melting 3 tablespoons butter and adding 3 tablespoons all-propose flour.
Stir well and cook for one minute to remove the raw flour flavor.
Add two cups of warm chicken or turkey stock to the skillet along with the roux
And continue stirring until the sauce thickens.
Add one cup of heavy cream to the skillet
along with the cooked and drained linguine noodles.
Stir well, and add the Parmesan cheese.
Time to add the turkey and mushroom mixture back into the skillet and stir well to combine thoroughly.
Add fresh parsley if desired.
Spoon the turkey and noodles evenly into a prepared (sprayed with cooking spray) 3 quart casserole dish and top with additional Parmesan cheese. Bake in a preheated 350 degree oven for 30 minutes.
Sprinkle the completed dish with chopped fresh parsley if desired and serve hot.
Ingredient substitutions
Don't have leftover turkey? No problem.
Leftover chicken or ham will work great as well as using rotisserie chicken, cooked and crumbled ground beef, or even canned tuna I think would be delicious!
No linguine in the pantry? That's ok, too. How about spaghetti, mostaccioli, or even elbow macaroni? Any pasta will work here as long as it's cooked and drained before adding it to the skillet.
Not a fan of mushrooms? Leave them out. I'll never tell a soul!
Additional add-in suggestions
- cooked bacon
- cooked pancetta
- spinach (cooked or raw)
- frozen peas
- French fried onions
- cooked green beans

Can this leftover turkey casserole be made in advance
You bet!
Make the casserole up to the point when it bakes in the oven, but instead let it cool on the counter. Cover the dish with plastic wrap and allow the unbaked casserole to sit in the refrigerator for up to 2 days.
To bake after refrigeration, allow the casserole to sit at room temperature for 45 minutes to an hour and then bake at 350 degrees for 30 minutes. Top with fresh Parmesan cheese and parsley before serving.
How many people will this casserole serve
It depends on how hearty your appetite is, but I wrote the recipe with the idea of comfortably serving eight people with moderate appetites.
This turkey linguine casserole will freeze beautifully after baking if you have a lot of leftovers for another day. Cool the leftovers entirely and store them in an airtight freezer container. Date the container and freeze for up to 4 months.
Thaw completely in the refrigerator overnight. Reheat in the microwave or a 350-degree oven, covered, until hot.
What is a roux
A roux is a thickening agent of equal parts fat to flour. In the case of this recipe, the fat is in the form of butter. I always use salted butter.
Once the three tablespoons of butter have melted in the skillet, stir in the three tablespoons of flour and cook, stirring for at least one minute.
The roux will be paste-like in consistency and light tan in color. The longer a roux cooks, the less thickening power it has, so cooking it for 1-2 minutes is ideal for removing the raw flour flavor but still thickens a sauce nicely.
Top tips for success
When preparing the pasta for this recipe, save a little of the pasta cooking water (½ cup or so) to loosen the sauce a little, if needed, before adding it to the casserole dish.
Since the casserole will finish baking in the oven, cut the cooking time down a few minutes on the pasta from what the package directions say. Cutting back on the cooking time will ensure the pasta is cooked properly.
