Why it works: Butter and cheese are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 7,962 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Baked Spaghetti with Eggs and Cheese
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Cook the spaghetti in a pot of fast boiling water until tender, then drain.
Butter a fireproof dish generously.
Assemble
Layer spaghetti, then slices of hard-cooked egg, seasoning with salt and pepper.
Repeat layers until the dish is full, ending with spaghetti.
Pour the white sauce over the top and sprinkle with cheese.
Dot with remaining butter in small pieces.
Bake and serve
Bake at 400°F (200°C) for 10 minutes.
Serve in the baking dish, garnished with sliced eggs and chopped parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Hard-cooked slices add protein structure and a rich, creamy body between the spaghetti layers.
- Spaghetti
- Forms the starchy base of the layers, giving the baked dish its body and bite.
- White sauce
- Adds moisture and creaminess that keeps the layers from drying out in the oven.
- Butter
- Adds richness and helps the top brown while preventing the dish from sticking.
- Grated cheese
- Melts over the top and browns, adding savory flavor and a golden crust.
The step that matters
Dotting and layering with butter. Butter spread over the dish and on top keeps the spaghetti from sticking and drying out, and helps the surface brown evenly in the oven.
