Easy & Comforting Chicken Tetrazzini: Your New Weeknight Favorite
There’s something incredibly satisfying about wrapping up a weekend with a hearty, homemade meal that also promises delicious leftovers for the week ahead. Sundays, especially, are the perfect time to engage in a bit of intentional cooking – whether it’s a simmering soup or a bubbling casserole – to lighten the load during busy weekdays. This culinary ritual not only offers a comforting end to the week but also provides a fantastic head start on meal planning, potentially covering up to three dinners without additional cooking.
Last Sunday, inspired by the desire for both comfort and convenience, I turned to a beloved classic from my trusted Better Homes and Gardens New Cookbook: a delightful Chicken Tetrazzini. This dish is a true marvel, marrying tender chicken, earthy mushrooms, and savory spaghetti in a rich, creamy sauce, all baked to golden perfection. It’s the kind of meal that evokes warmth and nostalgia, making it an ideal choice for a family dinner or a cozy night in.

The Magic of Chicken Tetrazzini: Quick Prep, Maximum Flavor
One of the most appealing aspects of this particular Chicken Tetrazzini recipe is its remarkable efficiency. The total combined prep and bake time hovers around a mere 35 to 45 minutes. If you’re quick with your chopping and measuring, you can easily have this savory casserole ready to go into the oven in about 30 minutes. The secret to this speed? Utilizing pre-cooked chicken. Opting for leftover chicken from a previous meal or, even better, a store-bought rotisserie chicken, eliminates the need for any additional cooking of the protein, saving you a significant amount of time and effort. This simple hack transforms a delicious, complex-tasting dish into a genuinely quick-assembly meal.
Chicken Tetrazzini is more than just a quick meal; it’s a celebration of classic flavors and textures. Originating in the early 20th century, this dish was named after opera singer Luisa Tetrazzini, hinting at its sophisticated yet accessible appeal. It typically features a creamy, cheese-infused sauce, often enriched with sherry, enveloping spaghetti, cooked chicken or turkey, and mushrooms. Our adapted version streamlines this classic, focusing on delivering that authentic, rich taste with minimal fuss.

Recipe: Chicken Tetrazzini
Yield: 6 servings
Prep Time: 20 minutes
Cook Time: 15 minutes
Total Time: 35 minutes
Adapted from Better Homes and Gardens New Cookbook
Ingredients
- 8 oz spaghetti
- 2 C sliced baby portobello mushrooms
- 1/2 C sliced green onions
- 2 tbsp Country Crock (or butter)
- 1/4 C all-purpose flour
- 1/8 tsp ground pepper
- 1/8 tsp ground nutmeg
- 1 C water
- 1 tsp chicken bouillon granules
- 1 C half and half
- 2 C shredded chicken (I used a rotisserie chicken)
- 2 tbsp Sherry (dry sherry recommended)
- 1 C shredded parmesan cheese, divided
- 1/2 C sliced almonds
- 2 tbsp fresh chopped parsley, for garnish
Instructions
- Cook the spaghetti: Bring a large pot of salted water to a boil. Add the spaghetti and cook according to package directions until al dente. Drain well and set aside.
- Sauté aromatics: In a large pot or Dutch oven, melt the Country Crock (or butter) over medium heat. Add the sliced baby portobello mushrooms and green onions. Cook, stirring occasionally, until the mushrooms are tender and have released their liquid, about 5-7 minutes.
- Prepare chicken broth: While mushrooms are cooking, bring 1 cup of water to a boil. Stir in the 1 teaspoon of chicken bouillon granules until completely dissolved. Set aside.
- Make the roux: Stir the all-purpose flour, ground pepper, and ground nutmeg into the mushroom mixture. Cook, stirring continuously for 1-2 minutes, to cook out the raw flour taste. This creates a roux that will thicken the sauce.
- Create the sauce base: Gradually whisk in the prepared chicken broth and the half and half. Mix well until smooth, ensuring no lumps. Reduce the heat to a simmer and continue to cook, stirring frequently, until the sauce thickens to your desired consistency. This usually takes about 5-8 minutes.
- Combine with main ingredients: Remove the pot from the heat. Stir in the shredded chicken, 1/2 cup of the shredded parmesan cheese, and the Sherry. Fold in the cooked spaghetti until it is evenly coated with the rich sauce.
- Assemble and top: Transfer the mixture into a 9×9 inch casserole dish (or similar size). Evenly sprinkle the remaining 1/2 cup of parmesan cheese and the sliced almonds over the top of the casserole.
- Bake to perfection: Preheat your oven to 350°F (175°C). Bake the Chicken Tetrazzini for 15 minutes, or until the cheese is melted and bubbly and the almonds are lightly toasted.
- Garnish and serve: Remove from oven. Before serving, sprinkle with fresh chopped parsley for a burst of color and freshness. Serve hot and enjoy!

Expert Tips for the Best Chicken Tetrazzini Experience
To ensure your Chicken Tetrazzini is nothing short of spectacular, consider these additional tips:
- Don’t Overcook the Pasta: Cook your spaghetti until it’s just al dente. It will continue to cook slightly in the oven, and you want it to retain a pleasant chew, not turn mushy.
- Embrace the Sherry: The dry sherry adds a subtle layer of complexity and depth to the sauce that truly elevates the dish. If you prefer not to use alcohol, you can substitute with an equal amount of chicken broth or even a splash of white grape juice for a touch of sweetness.
- Cheese Varieties: While Parmesan is traditional and delicious, feel free to experiment with other cheeses. A blend of Gruyere, Monterey Jack, or even a sharp cheddar can add different flavor profiles.
- Add More Vegetables: Enhance the nutritional value and texture by adding other vegetables. Peas, carrots, bell peppers, or even a handful of fresh spinach can be stirred in with the chicken.
- Make Ahead Option: You can assemble the entire casserole (up to step 7) ahead of time. Cover it tightly and refrigerate for up to 24 hours. When ready to bake, you might need to add an extra 5-10 minutes to the baking time to ensure it’s heated through.
- Freezing Instructions: Chicken Tetrazzini freezes beautifully! Once completely cooled, cover the casserole dish tightly with plastic wrap and then foil. Freeze for up to 3 months. Thaw overnight in the refrigerator before baking at 350°F (175°C) until bubbly and heated through, possibly 30-45 minutes.
