Ingredients

  • 1 large poblano chile
  • 2 1/2 tablespoons canola oil
  • Kosher salt and freshly ground black pepper
  • 1 1/2 pounds ground chuck (80 percent lean) or ground turkey (90 percent lean)
  • 4 hamburger buns, split; toasted, if desired (see below)
  • 12 blue or yellow corn tortilla chips
  • 1 tablespoon unsalted butter
  • 1 tablespoon all-purpose flour
  • 1 1/2 cups whole milk
  • 8 ounces Monterey Jack cheese, coarsely grated (about 2 cups)
  • Kosher salt and freshly ground black pepper

Method

  • Preheat the oven to 375 degrees F.
  • Put the chile on a rimmed baking sheet, rub with 1 tablespoon of the oil, and season with salt and pepper.
  • Roast in the oven until the skin of the chile is blackened, about 15 minutes.
  • Remove the chile from the oven, place in a bowl, cover with plastic wrap, and let the chile steam for 15 minutes.
  • Peel, stem, and seed the chile and then coarsely chop it.
  • To make the queso sauce, melt the butter in a small saucepan over medium heat.
  • Whisk in the flour and cook for 1 minute.
  • Add the milk, increase the heat to high, and cook, whisking constantly, until slightly thickened, about 5 minutes.
  • Remove from the heat and whisk in the cheese until melted; season with salt and pepper.
  • Keep warm.
  • Divide the meat into 4 equal portions (about 6 ounces each).
  • Form each portion loosely into a 3/4-inch-thick burger and make a deep depression in the center with your thumb.
  • Season both sides of each burger with salt and pepper.
  • Cook the burgers, using the remaining 1 1/2 tablespoons oil.

  • Place the burgers on the bun bottoms and top each with a few tablespoons of queso sauce, chips, and some of the poblano.
  • Cover with the bun tops and serve immediately.
  • Toasted Burger Buns
  • I think the taste and the texture of buns are best when lightly toasted.
  • To toast a bun on a grill, grill pan, or griddle, split the bun open, place it cut side down on the grill, and grill until light golden brown, about 10 seconds.
  • Alternatively, you can place the split bun halves cut side up on a baking sheet and cook them under a preheated broiler until light golden brown, about 30 seconds.
  • Keep a close eye on them and don't let them get too brown or else that texture will take on a life of its own and defeat the purpose of starting with a soft bun.
