Recipe Variations, Tips and Substitutions
- Cheese – You can use a combination of Parmesan cheese with Gruyere cheese or Swiss cheese in place of cheddar cheese.
- Pasta – Turkey Tetrazzini is typically made using linguine. You could adapt using fettuccine, thin spaghetti or bucatini or even egg noodles, in a pinch.
- Half and Half or Heavy Cream – You can use heavy cream for the sauce for an even more decadent texture and flavor.
- White Cheese – I tend to lean toward a white cheese for this recipe. You can use either sharp white cheddar cheese or nutty Gruyere cheese would also work.
- Topping – You can use fresh breadcrumbs, Italian seasoned dried breadcrumbs or cracker crumbs such as crushed Ritz or Club crackers.
- Protein – You can make this with diced cooked chicken or peeled shrimp for a seafood tetrazzini.
- Use a Large Pot and it Doubles as a Large Bowl – For easy clean-up use a large pot to make the sauce and you can dump everything into it to combine.

Storage and Leftovers
- Make-Ahead Tip – You can fully assemble this tetrazzini and pop it into the refrigerator one day in advance. Take it out of the fridge about 20 minutes prior to baking, to allow it to warm to room temperature. Top with the breadcrumb topping just before baking. You may also need to add 5-10 minutes to the baking time.
- Leftovers – Store leftover Turkey Tetrazzini in an airtight container chilled in the refrigerator for up to 3 days.
- Reheating – Reheat in single servings in the microwave or in a preheated 350°F oven just until heated through.
- Freezer – Store frozen for up to 2 months. Thaw in the fridge and reheat just before serving.

Made this last night just used less mushrooms and used a little less pasta just incase it came out dry and it was perfect, my husband just said it needs more crunchy topping. Might add fresh spinach as well next time just for extra veggies in it.
Love this recipe. It is delicious. Makes a lot and glad I put it in a larger casserole pan. Used swiss cheese for the 2 cups.
I’m happy you enjoyed it, thanks!
