Recipe: Bobby Flay's Green Chile Cheeseburgers

For this week's recipe, I'm bringing something from king of the grill Bobby Flay.

Flay is a celebrity chef who hosts several shows on the Food Network channel and owns restaurants throughout the country; he's best known for his grilling technique.

Here's his recipe for green chile cheeseburgers, via foodnetwork.com:

Ingredients

Queso Sauce:

1 tablespoon unsalted butter
1 tablespoon all-purpose flour
1 cup whole milk
12 ounces Chihuahua or Monterey jack cheese, coarsely grated
1/4 cup grated Parmesan
Kosher salt and freshly ground black pepper
Green Chile Relish:
1 medium poblano chile, roasted, peeled, seeded and thinly sliced
2 Hatch chiles, roasted, peeled, seeded and thinly sliced
1 serrano chile, roasted, peeled, seeded and thinly sliced
1/4 cup red wine vinegar
1 tablespoon honey
2 tablespoons extra-virgin olive oil
3 tablespoons chopped fresh cilantro leaves
Kosher salt and freshly ground black pepper

Pickled Red Onions:

1 1/2 cups red wine vinegar
1/4 cup water
2 tablespoons sugar
1 tablespoon kosher salt
1 medium red onion, peeled, halved and thinly sliced

Burgers:

1 tablespoon canola oil
1 1/2 pounds ground beef
Kosher salt and freshly ground black pepper
4 hamburger buns, split and lightly toasted
12 blue or yellow corn tortilla chips, coarsely crushed
For 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; add the Parmesan and season with salt and pepper, to taste. Keep warm.

For the relish:

Combine all ingredients in a bowl and season with salt and pepper, to taste.

For the pickled red onions:

Bring vinegar, water, sugar and salt to a boil in a small saucepan over medium heat. Remove from the heat and let cool for 10 minutes. Put the onions in a medium bowl, pour the vinegar over, cover and refrigerate for at least 4 hours and up to 48 hours before serving.

For the burgers:

Heat a griddle or large saute pan over high heat. Add the oil and let it heat until it begins to shimmer.

Shape the ground beef with your hands into 4 round patties about 1 1/2 inches thick and season each burger on both sides with salt and pepper, to taste. Cook the burgers until golden brown on both sides and cooked to medium, about 8 minutes.

Put the burgers on the buns and top each with a few tablespoons of the queso sauce, relish, onions and chips.
