Ingredients You’ll Need

• Fettuccine: Creates the hearty base of the dish. Its flat, wide shape perfectly captures and holds the creamy sauce.
• Rotisserie Chicken: The ultimate time-saver that adds rich, pre-cooked flavor. The slightly roasted notes from the skin enhance the overall dish.
• Butter: Don’t skimp here—it creates richness and depth throughout the entire recipe, from sautéing vegetables to creating that irresistible golden topping.
• Mushrooms: Button mushrooms provide an earthy depth that balances the richness of the cream sauce. They also add wonderful texture.
• Onion and Garlic: These aromatic foundations build the flavor profile of the sauce. When they hit the hot pan, the kitchen instantly smells amazing.
• Fresh Thyme: Brings a subtle herbal note that cuts through the richness and complements the mushrooms beautifully.
• White Wine: Adds acidity and depth, while helping to deglaze all those flavorful browned bits from the pan. Choose something you’d enjoy drinking!
• Milk and Heavy Cream: Creates that luxurious, velvety sauce that defines tetrazzini. The combination gives the perfect balance of richness without being too heavy.
• Chicken Broth: Adds savory depth to the sauce while keeping it from being too thick or rich.
• Flour: Works as a thickening agent for the sauce, giving it that perfect consistency that clings to the pasta.
• Nutmeg: Just a touch brings subtle warmth and complexity that enhances cream sauces magically.
• Parmesan Cheese: Provides a salty, umami punch in the crunchy topping. Fresh-grated is always best!
• Breadcrumbs: Creates that irresistible golden, crunchy top layer that adds textural contrast to the creamy dish below.
• Fresh Parsley: Brightens the finished dish with color and a fresh herbal note that balances the richness.

Variations

Seafood Tetrazzini

Swap the chicken for a mixture of seafood like shrimp, scallops, and crab meat. Reduce the cooking time when sautéing to avoid overcooking the delicate seafood.

Turkey Tetrazzini

Perfect for Thanksgiving leftovers! Simply replace the chicken with leftover turkey meat. The flavors marry beautifully, and it’s a great way to transform holiday leftovers.

Vegetarian Version

Skip the meat entirely and double up on mushrooms—try a mix of varieties like cremini, shiitake, and oyster mushrooms for complex flavor. Add some peas or roasted red peppers for color and nutrition.

Gluten-Free Adaptation

Use your favorite gluten-free pasta and substitute the all-purpose flour with a one-to-one gluten-free flour blend. Ensure your breadcrumbs are also gluten-free.

How to Make Chicken Tetrazzini

Step 1: Prepare Pasta and Preheat

Preheat your oven to 425°F and coat a large casserole dish with nonstick spray. Cook the fettuccine in generously salted water until just al dente—remember it will continue cooking in the oven, so keep it slightly firm. After draining, rinse with cold water and spread on a baking sheet to prevent clumping.

Step 2: Sauté Vegetables

In a large skillet, heat olive oil and butter over medium heat. Add mushrooms and onions with a light seasoning of salt and pepper. Cook until the onions become translucent and the mushrooms release their moisture and become tender—about 5-7 minutes. Patience pays off here as properly cooked mushrooms develop much deeper flavor.

Step 3: Deglaze and Build Flavor

Add the garlic, fresh thyme, and white wine to the skillet. Use a wooden spoon to scrape up any browned bits from the bottom—these contain concentrated flavor! Let the mixture simmer for about 2 minutes until slightly reduced, then transfer to a bowl and set aside.

Step 4: Prepare the Cream Base

In a medium saucepan, gently heat the milk, cream, and chicken broth until steam rises from the surface. Don’t let it boil—just warm it through to ensure your sauce will be smooth.

Step 5: Make the Roux

In your original skillet, melt 3 tablespoons of butter over medium heat. Sprinkle flour over the melted butter while whisking constantly. Continue whisking until the mixture turns light golden brown, about 2 minutes. This brief cooking removes the raw flour taste.

Step 6: Create the Sauce

Slowly add the warm milk mixture to the roux, whisking continuously to prevent lumps. Add nutmeg, seasoned salt, kosher salt, and black pepper. Bring just to a boil, then immediately reduce heat and simmer for 8-10 minutes, whisking frequently, until the sauce coats the back of a spoon.

Step 7: Combine and Assemble

Remove the sauce from heat and add the chicken, mushroom-onion mixture, cooked fettuccine, and half the parsley. Mix everything thoroughly until well combined. Transfer this mixture to your prepared casserole dish, then top evenly with breadcrumbs and Parmesan cheese.

Step 8: Add Final Touch and Bake

Melt the remaining butter and drizzle it over the breadcrumb topping. Bake at 425°F for 30 minutes until gloriously golden brown and bubbling around the edges. Let rest for 5-10 minutes before serving to allow the sauce to set slightly.

Pro Tips for Making the Recipe

• Don’t Rush the Mushrooms: Cook them until they’ve released their liquid and it has evaporated—this concentrates their flavor and improves texture.
• Warm Your Liquids: Heating the milk, cream, and broth before adding to the roux prevents lumps and helps the sauce thicken more evenly.
• Season in Layers: Add a little salt and pepper at each stage of cooking rather than all at once at the end—this builds deeper flavor throughout the dish.
• Rest Before Serving: Those 5-10 minutes of resting time are crucial. The dish will be more cohesive, and you’ll avoid burning the roof of your mouth on molten cream sauce!
• Cheese Upgrade: For even more flavor, try using a mix of Parmesan and Gruyère in the topping—the Gruyère melts beautifully and adds wonderful depth.

How to Serve

Perfect Pairings

Chicken Tetrazzini is rich and hearty, so it pairs wonderfully with lighter sides. A crisp green salad with a tangy vinaigrette provides the perfect contrast to the creamy casserole. Roasted asparagus or steamed green beans also make excellent accompaniments, adding color and freshness to the plate.

Bread Selection

A slice of garlic bread or warm crusty bread is perfect for soaking up any extra sauce. If you’re feeling ambitious, homemade soft dinner rolls elevate the entire meal to new heights.

Wine Suggestions

If you’re serving wine, consider pouring the same white wine you used in the recipe. A crisp Sauvignon Blanc or lightly oaked Chardonnay complements the creamy sauce beautifully. For red wine lovers, a light Pinot Noir works surprisingly well.

Make Ahead and Storage

Make Ahead Instructions

Prepare the entire dish up to the baking stage, cover with foil, and refrigerate for up to 24 hours. When making ahead, increase the chicken broth to 2 cups as noted in the recipe to prevent the pasta from absorbing too much liquid and drying out. When ready to bake, let it sit at room temperature for 30 minutes, then bake as directed, possibly adding 5-10 extra minutes since you’re starting with a cold dish.

Storing Leftovers

Store cooled leftovers in an airtight container in the refrigerator for up to 3-4 days. The flavors actually develop and improve after a day in the fridge!

Freezing

For freezing, assemble the tetrazzini but don’t bake it. Cover tightly with plastic wrap and aluminum foil, and freeze for up to 3 months. Thaw overnight in the refrigerator before baking. Alternatively, freeze individual portions of baked tetrazzini for quick lunches or dinners.

Reheating

Reheat individual portions in the microwave, covered, at 50% power for best results. For a full casserole, cover with foil and reheat in a 350°F oven until warmed through, about 20-30 minutes. Add a splash of milk or cream if it seems dry.

FAQs

Can I use a different pasta shape for chicken tetrazzini?
Absolutely! While fettuccine is traditional, any pasta that holds sauce well works beautifully. Linguine, spaghetti, or even penne are great substitutions. Just make sure to cook the pasta al dente since it will continue cooking in the oven. The sauce-to-pasta ratio might need slight adjustments with differently shaped pasta, so trust your instincts if the mixture looks too dry or wet before baking.

Why did my sauce separate or become grainy?
This usually happens when the sauce is heated too quickly or at too high a temperature. The key is to add the warm (not hot) milk mixture to the roux slowly while constantly whisking, and to maintain a gentle simmer rather than a boil. If your sauce looks like it’s starting to separate, immediately remove it from heat and whisk vigorously until smooth again before proceeding with the recipe.

Can I make this recipe lighter or lower in calories?
Yes, while it won’t have quite the same luxurious texture, you can make a lighter version. Try substituting 2% milk for the whole milk, and half-and-half for the heavy cream. You can also reduce the butter slightly. Consider adding more vegetables like peas or bell peppers to bulk up the dish while adding nutrition. The flavor will still be delicious, though the sauce won’t be quite as rich.

My casserole seems too dry/too wet. What went wrong?
For a dry casserole, the pasta may have been overcooked initially or the sauce may have reduced too much. Next time, cook the pasta more al dente or add extra liquid to the sauce. For a wet casserole, the sauce might not have thickened enough before assembly. Make sure to simmer until it coats the back of a spoon, and allow the baked casserole to rest for at least 10 minutes before serving, which gives the sauce time to set.
