  • serrano chiles – stems removed 
  • fresh garlic – unpeeled 
  • yellow onion – peeled 
  • 1/4 cups (60 ml)  fresh cilantro

Step 1

Heat the oil in a Cast Iron Skillet or Dutch oven. Add onion, and season with the salt, pepper and garlic. Cook until translucent, set aside.

Step 2

In a large bowl, combine bread, Hatch chiles, sour cream, sautéed onion, tomatillo salsa, and cilantro until well blended. Pour the mixture into a buttered 9 x 13 Rectangular Drip Pan.

Step 3

Whisk the eggs with the half-and-half and pour over the bread mixture. Adjust the seasonings, if needed, cover and refrigerate overnight so it will set.

Step 4

The next day, set the EGG for indirect cooking with the convEGGtor at 350°F/176°C. Remove the casserole from the refrigerator 30 minutes before you plan to bake it. Bake the casserole until set and golden brown. This should take about 1 hour. Top with salsa and sour cream, if desired, and serve hot.
