Why it works: Mushroom and chicken are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 4,172 recipes. Both carry 1-butyl acetate, which smells fruity, banana. The science ↓
Chicken Tetrazzini
8 personsIngredients
Directions
Prepare
Preheat the oven to 450°F.
Grease the baking dish.
Fill a pot with 4 quarts of water or enough to fully boil the pasta.
Add 1 tablespoon salt to the water.
Bring the water to a boil over high heat.
Cook the mushrooms
Melt 2 tablespoons butter in a skillet over medium heat.
Sauté the sliced mushrooms and finely chopped onion, stirring occasionally, until the liquid evaporates (about 7–8 minutes).
Add the minced thyme, salt, and pepper to the skillet.
Continue cooking until the mushrooms are brown (another 8–10 minutes).
Set the mushroom mixture aside in a bowl.
Cook the pasta
When the water is boiling, add the spaghetti.
Cook the spaghetti until al dente (about 8–12 minutes).
Taste periodically to ensure the pasta does not overcook before baking.
Make the sauce and bake
Return the skillet to the stove and melt 4 tablespoons butter over medium heat.
Add the all-purpose flour to the melted butter to make a roux.
Whisk the roux until smooth with a light golden color (about 1–2 minutes).
While whisking, add a little chicken broth at a time to the roux. Fully incorporate the broth until smooth before adding more broth.
Increase the heat to medium-high and simmer until the sauce thickens (about 3–4 minutes).
Remove the sauce from the heat.
Stir in the grated Parmesan cheese, salt, and pepper.
Add half of the lemon juice to the sauce. Continue adding lemon juice to taste.
Combine the shredded rotisserie chicken, cooked spaghetti, sautéed mushrooms, frozen peas, and sauce together.
Spread the combined mixture into the greased baking dish.
Sprinkle the breadcrumbs evenly on top.
Bake until the dish is heated through and the breadcrumbs are light brown, about 12–14 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried spaghetti
- Forms the bulk of the dish and gives it its chewy, pasta-based structure.
- All-purpose flour
- Thickens the butter and broth into a smooth sauce as a roux.
- Butter
- Carries flavor, enriches the sauce, and forms the base of the roux.
- Parmesan cheese
- Adds savory, salty depth and helps the sauce cling to the pasta.
- Mushrooms
- Add earthy flavor and moisture, and brown for savory depth.
- Rotisserie chicken
- Provides the main protein and substance of the dish.
The step that matters
Adding the broth to the roux. Adding broth gradually while whisking lets the starch in the flour hydrate evenly, producing a smooth sauce instead of lumps.
Swap the onion
