My One Pot Chicken Tetrazzini recipe is everything a comfort meal should be. Perfectly creamy (without being overwhelmingly heavy), saucy with tender noodles, and very mushroom-forward. It’s made with real butter (no condensed soup!), fresh garlic, and a touch of white wine for the perfect, rich, smooth, and savory pasta.
This super cheesy and comforting chicken tetrazzini recipe is one of my all-time dinner favorites, right up there with my creamy chicken pasta and tuna casserole. I have quite a few one-pot recipes on the blog (a quick search will show you there are plenty to choose from), but this is my take on the classic.

Ingredients
- 4 tablespoons butter
- 1 chicken breast boneless skinless cut into cubes
- 2 cups mushrooms sliced
- ¼ cup all purpose flour
- 3 cups chicken broth
- 1 cup milk
- 8 ounces spaghetti broken in half
- ¼ cup Parmesan cheese
- 2 tablespoons parsley chopped
- ½ teaspoon salt
- 1 teaspoon pepper
- 1 teaspoon garlic powder
Step by Step Instructions
1. Melt the Butter
Set a large pot over medium heat. Add butter and let it melt fully. Swirl it around so it coats the bottom evenly.
2. Cook the Chicken
Add chicken cubes to the pot. Stir and cook until the outside turns white and lightly golden. This step builds flavor early.
3. Add the Mushrooms
Stir mushrooms into the pot. Let them cook until soft and slightly darker. They release moisture and deepen the taste.
4. Sprinkle the Flour
Shake flour evenly over the chicken and mushrooms. Stir well so no dry spots remain. This thickens the sauce later.
5. Pour in Liquids
Slowly add chicken broth while stirring. Follow with milk and keep stirring until smooth. The mixture should look creamy.
6. Add Pasta and Seasoning
Place spaghetti into the pot and press it down gently. Sprinkle salt, pepper, and garlic powder over the top.
7. Simmer Until Tender
Cover the pot and let everything cook on low heat. Stir occasionally so pasta stays loose. Cook until noodles turn soft.
8. Finish with Cheese
Turn off the heat and stir in Parmesan cheese. Sprinkle parsley on top and mix gently before serving.
Tips & Variations
- Add a small splash of milk near the end.
- Increase mushrooms for deeper flavor.
- Try a sharper hard cheese for more bite.
- Stir often to keep noodles smooth.
Serving Suggestions
One Pot Chicken Tetrazzini works well as a full meal on its own. Serve it hot with a simple green salad to add freshness. A slice of warm bread on the side helps scoop up extra sauce.
When I serve this for guests, I sprinkle extra parsley on top and place the pot right on the table. It feels relaxed and welcoming.
