Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the sauce
Prepare a cream sauce.
Mix in the grated Parmesan and Gruyère cheese.
Warm the macaroni in the cheese mixture.
Bake and serve
Pour the mixture into a shallow oven‑safe dish.
Top with breadcrumbs, grated cheese, and melted butter.
Bake in a 400°F (200°C) oven until golden brown.
Serve in the dish it was baked in.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the bulk of the dish and gives it a substantial, starchy body.
- Parmesan cheese
- Adds sharp, savoury flavour and helps the sauce turn rich and cohesive.
- Gruyère cheese
- Melts smoothly and adds nutty flavour and stretch to the sauce.
- Cream or milk
- Forms the liquid base of the sauce, providing moisture and a creamy texture.
- Breadcrumbs
- Form a crisp, golden topping that contrasts with the soft interior.
- Butter
- Promotes browning of the topping and adds richness.
The step that matters
Bake until golden brown. Baking too briefly leaves the sauce loose and the topping pale, while overbaking can dry the cheese and make it grainy. Watching for an even golden colour helps the sauce set and the topping brown properly.
