Scalloped Oysters

Scalloped oysters is an old American holiday dish, the kind that used to crowd church-supper tables and Thanksgiving spreads up and down the East Coast. This version moves the whole thing to the microwave, which sounds wrong until you try it. Ten minutes start to finish.

The technique runs in two short stages. First the aromatics: butter, minced onion, celery, garlic juice, lemon, and parsley get four minutes covered to soften and release their flavor into the fat. Then the oysters go in a separate bowl for ninety seconds, just long enough for the edges to curl, which is the visual cue they’re cooked through.

Everything joins up with milk and crushed crackers, the topping gets a layer of grated cheese, and four more minutes uncovered finishes the casserole. The crackers absorb the milk and oyster liquor, which gives this dish its signature texture: somewhere between a stuffing and a creamy bake.

Underdone oysters turn rubbery the moment you reheat them. Pulling at the curled-edge mark keeps them tender.

Kitchen Tips

• Drain the oysters well or the casserole turns watery. Save the liquor for chowder, don’t pour it into this dish.
• Use saltine or oyster crackers for the most traditional flavor and texture.
• Sharp cheddar or Gruyère on top reads more like the oven-baked classic than mild cheese.
• Microwaves vary wildly. Check at the minimum time and add 30 seconds at a stretch.

Variations

• Bake at 400°F (205°C) for 15 to 20 minutes for the traditional crisper top if you have the time.
• Stir a tablespoon of dry sherry into the milk for an old-fashioned restaurant-style edge.
• Layer cooked bacon crumbles through the casserole for a smoky variation.
