How to Make Chicken Tetrazzini Casserole
Step 1: Prepare the Chicken and Pasta
Start by cooking spaghetti according to the package instructions until al dente. Drain and set aside. If you don’t have leftover chicken, poach or roast chicken breasts and shred them for the casserole’s base.
Step 2: Sauté Mushrooms and Aromatics
In a large skillet, melt butter and sauté chopped onions and garlic until fragrant and translucent. Add sliced mushrooms and cook until soft and lightly caramelized to bring out natural sweetness and depth.
Step 3: Make the Creamy Sauce
Whisk flour into the butter and mushroom mixture to create a roux, cooking for a minute or two. Gradually stir in chicken broth and milk, whisking constantly until the sauce thickens. Mix in the cream of mushroom soup, season with salt, pepper, and a pinch of nutmeg, and simmer gently to combine flavors.
Step 4: Assemble the Casserole
In a large mixing bowl, combine cooked chicken, spaghetti, sautéed mushrooms and onions, and the creamy sauce. Add half of your cheese blend and stir until everything is evenly coated.
Step 5: Bake to Perfection
Transfer the mixture to a greased casserole dish and sprinkle the remaining cheese on top. Bake in a preheated oven at 350°F (175°C) for 25-30 minutes until the top is golden and bubbly. Let it rest a few minutes before serving.
Pro Tips for Making Chicken Tetrazzini Casserole
- Don’t Overcook Pasta: Slightly undercook the spaghetti as it will continue softening in the oven.
- Use Quality Cheese: Freshly grated mozzarella and Parmesan melt better and add superior flavor.
- Balance the Sauce: If the sauce is too thick, add a splash of broth; if too thin, cook it longer to reduce.
- Rest Before Serving: Letting the casserole sit allows flavors to meld and makes it easier to slice.
- Add Crunchy Topping: Toasted breadcrumbs or crushed crackers sprinkled on top create a satisfying crunch.
