Why it works: Cheese and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 2,130 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Tuna Casserole
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Cook the noodles in chicken broth, adding enough water to prevent stiffness.
Butter a casserole dish.
Layer and bake
Layer noodles, then add a thin layer of tuna and sprinkle with cheese.
Repeat layering until the dish is full.
Top with bread crumbs and additional grated cheese.
Bake in the oven until the cheese is well melted at 350°F (175°C).

Flour and egg barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fine egg noodles
- Form the bulk of the casserole and absorb broth, giving a soft, tender texture.
- Chicken broth
- Cooks the noodles and adds savory moisture to the dish.
- Tuna
- Supplies the main protein and savory flavor in each layer.
- Grated cheese
- Melts to bind the layers together and add richness and browning.
- Flour
- Thickens the sauce, giving the casserole body and structure.
The step that matters
Adding enough water while cooking the noodles. Noodles cooked only in broth can absorb liquid and turn stiff during baking. Adding enough water keeps them tender, so the casserole stays moist and soft rather than dry.
