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 Gruyere cheese.
Assemble and bake
Warm the macaroni in the cheese mixture.
Pour the mixture into a shallow oven-safe dish.
Top with breadcrumbs, grated cheese, and a little melted butter.
Bake in a 400°F (200°C) oven until golden brown.

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 the gratin its body.
- Parmesan cheese
- Adds savory, salty flavor and helps the sauce thicken and brown.
- Gruyere cheese
- Melts smoothly into the sauce and adds nutty flavor and stretch.
- Cream or milk
- Forms the sauce that coats the pasta and keeps the gratin moist.
- Breadcrumbs
- Form a crisp topping that browns in the oven.
The step that matters
Bake until golden brown. Cheese sauces can turn oily or grainy if overheated, while underbaking leaves the top pale and the sauce loose. Watching for an even golden top and a bubbling edge helps the sauce set properly.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
