Best Ways to Enjoy It
Serve this Chicken Tetrazzini while it is steaming hot and bubbly. It pairs beautifully with a crisp green salad and light vinaigrette. You can also serve it with warm garlic bread for dipping. Set the table, light a candle, and enjoy a peaceful meal together.
Storage & Reheating
Leftovers stay fresh in the fridge for up to three days. Keep them in an airtight container to maintain the creamy texture. To reheat, place a portion in the oven at 350°F for ten minutes. You can also use the microwave for a quick weekday lunch. If the sauce seems thick, add a splash of milk before heating.
Recipe Tips
- Don’t skip the step of breaking the spaghetti in half for easier eating.
- Avoid overcooking the pasta since it will soften more in the oven.
- Use a rotisserie chicken to save time on busy weeknights.
- Whisk the flour and butter well to prevent any lumps in your sauce.
- Add a handful of frozen peas for a pop of color and nutrition.
- Let the dish rest for five minutes so the sauce sets perfectly.
- For a holiday twist, use leftover Thanksgiving turkey instead of chicken.
Easy Flavor Ideas
- Swap the sherry for extra chicken broth if you prefer no alcohol.
- Use gluten-free pasta and flour to make this dish allergy-friendly.
- Add a pinch of nutmeg to the sauce for a deeper winter flavor.
- Try using sharp cheddar instead of mozzarella for a bolder cheese taste.
Common Questions
Can I make this ahead of time?
Yes, you can assemble the casserole a day in advance. Keep it covered in the fridge and bake it when you are ready. You may need to add five extra minutes to the baking time.
What if I don’t have dry sherry?
You can substitute the sherry with white grape juice or more chicken broth. It will still taste delicious and creamy. The sherry just adds a subtle, classic depth to the sauce.
Will my kids eat the mushrooms?
If your kids are picky, chop the mushrooms very finely before cooking. They will blend into the sauce and add great flavor. You can also leave them out if you prefer.
I hope this cozy meal brings a little extra warmth to your home this season. It is one of my favorite ways to slow down and enjoy a quiet evening. Give it a try and let the creamy goodness comfort you.
