Oysters Au Gratin

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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Preheat the oven to 400°F (200°C).

  2. Remove the oysters from their shells and place them in a baking dish.

Make the cheese sauce

  1. In a saucepan, melt the butter over medium heat.

  2. Stir in the flour and cook for 1 minute.

  3. Gradually add the milk, stirring constantly until thickened.

  4. Add the cheese, black pepper, salt, and paprika; stir until the cheese melts.

Bake and serve

  1. Pour the cheese sauce over the oysters.

  2. Sprinkle breadcrumbs on top and bake for 15 minutes until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Oysters
Provide the main seafood and the delicate, briny flavor at the center of the dish.
Butter
Enriches the sauce with fat and flavor while helping form the roux base.
Flour
Thickens the milk into a smooth sauce when cooked with the butter.
Milk
Forms the liquid base of the sauce, which thickens as it heats.
Grated cheese
Adds richness and melts into the sauce, giving the gratin its creamy body.
Breadcrumbs
Form a crisp topping that browns in the oven.

The step that matters

Thickening the sauce. Flour must be cooked briefly with butter and milk must be added gradually while stirring constantly. This keeps lumps from forming and lets the starch swell evenly into a smooth sauce that holds together under the topping.
