Step 5: Prepare the Egg Mixture

  1. In a medium bowl, whisk together eggs, milk, Dijon mustard, and Worcestershire sauce until smooth.

Step 6: Bake to Golden Perfection

  1. Place the baking dish in the preheated oven and bake for 25–30 minutes.
  2. Check for doneness—the top should be golden brown and the egg mixture fully set.

Step 7: Garnish and Serve

  1. Remove from the oven and let the bake rest for 5 minutes to set slightly.
  2. Sprinkle with fresh parsley before serving.
  3. Slice into portions and serve warm.
