Step-by-Step Guide to Making Chicken Tetrazzini

1. Preheat and Prep: Set oven to 350°F (175°C). Grease a 9×13-inch baking dish.
2. Cook Pasta: Boil spaghetti to al dente (about 8 minutes). Drain and rinse briefly to stop cooking.
3. Mix Sauce Base: In a large bowl, whisk canned soups, sour cream, melted butter, broth, salt, pepper, and garlic powder until smooth.
4. Incorporate Fillings: Fold in cooked chicken and any veggies like peas or mushrooms. Add pasta and toss evenly to coat.
5. Assemble: Transfer to baking dish. Sprinkle cheeses evenly on top.
6. Bake: Cover with foil and bake 30 minutes. Uncover and bake 15 more minutes until cheese bubbles and browns.
7. Rest and Serve: Let stand 10 minutes. Garnish with parsley.

Total time: 15 minutes prep, 45 minutes bake. Pro tip: For crispier topping, broil 2 minutes at end.

Pro Tips for the Best Chicken Tetrazzini

• Use room-temperature ingredients for a lump-free sauce.
• Cook pasta al dente—it finishes in the oven.
• Shred chicken finely for even distribution.
• Adjust broth if sauce seems too thick; aim for pourable consistency.
• Freshly shredded cheese melts better than pre-shredded.

Common pitfalls: Overcooking pasta leads to mushiness; underbaking leaves it cold in the center.
