  1. Cook pasta. Cook pasta al dente, according to package directions. Then drain the pasta, reserving 1/2 cup pasta water.
  2. Make the sauce. Melt the butter over medium-heat in a skillet. Add in the chopped onions and cook for 3 to 5 minutes. Then add minced garlic and cook an additional minute. Next add in the turkey, cream of mushroom soup and sour cream. If you need to thin the sauce out a little, add in the pasta water.
  3. Combine. Toss together the sauce and noodles, then pour mixture in a buttered 8×8″ baking dish.
  4. Bake in the oven. Top with cheese and bake in oven at 350°F for 25-30 minutes, or until the top is bubbly and lightly golden.

Tips and Substitutions

This tetrazzini casserole dish is perfect for using leftovers and having an extra meal during the week. Here are a few tips and variations to help make your casserole even better. Create the best dinner for your family just the way you like it using these ideas!

  • Can use homemade cream of mushroom soup if you’d prefer to make your own.
  • Can add in 1/2 cup sliced mushrooms with the chopped onions.
  • You can also use cooked chicken instead of turkey for a chicken tetrazzini.
  • Cook the pasta al dente. Don’t overcook because it will cook even more in the oven. I like to use linguine noodles, but cooked spaghetti or even egg noodles would taste delicious.
  • For more texture, feel free to sprinkle some bread crumbs on top.
  • You can substitute chopped onions and minced garlic with 1/2 teaspoon both onion powder and garlic powder. Simply mix the seasonings with the melted butter.
  • Frozen peas also taste yummy in this dish. Mix them in when you stir together the sauce and noodles.
