I serve this dish as an appetizer and often add whatever ingredients I have handy, such as mushrooms or sun-dried tomatoes. Whether I serve it “as is” or jazz it up, it’s always delicious. —Todd Noon, Galloway, New Jersey


  • 5 to 6 medium sweet onions, sliced and separated into rings
  • 1/2 cup butter, softened, divided
  • 2 cans (6 ounces each) lump crabmeat, drained, divided
  • 3 cups shredded Swiss cheese
  • 1 can (10-3/4 ounces) condensed cream of mushroom soup, undiluted
  • 1/2 cup evaporated milk
  • 1/2 teaspoon salt
  • 1/4 teaspoon pepper
  • 12 to 16 slices French bread (1/4 inch thick)


  1. In a large skillet, saute onions in 1/4 cup butter until tender. Remove from the heat; gently stir in half of the crab. Spread into a greased 13x9-in. baking dish. Top with remaining crab. Combine the cheese, soup, milk, salt and pepper; spoon over crab.
  2. Spread remaining butter over one side of each slice of bread; place buttered side up over casserole. Bake, uncovered, at 350° for 35-45 minutes or until golden brown.
