Method

  • Preheat the oven to 375*F.
  • Heat the oil in a large nonstick skillet over medium-high heat.

  • Reduce the heat and cook, stirring occasionally, until the onions are very tender and any liquid is evaporated, about 15 minutes.
  • Stir in the thyme.
  • Spoon the mixture into a shallow 1-quart round baking dish or a 9-inch glass pie plate.
  • Combine the milk, cheese, eggs, mustard, and salt in a bowl; beat with a whisk until blended.
