In Livermore, California, Diane Caragio assembles this saucy side dish days before she needs it. "Take one out of the freezer in the morning, and it's ready to be baked for dinner," she offers. "It's great with turkey or ham."

  • 3 teaspoons salt
  • 3 cups sliced fresh mushrooms
  • 10 tablespoons butter, divided
  • 2 teaspoons lemon juice
