From Bobby Flay's Burgers, Fries, and Shakes, page 63.
1 large poblano chile
2 1/2 Tbs. canola oil
Kosher salt and freshly ground pepper
1 1/2 lbs. ground chuck (80/20) or ground turkey (90/10)
4 hamburger buns, split; toasted, if desired
12 blue or yellow corn tortilla chips
1 Tbs. unsalted butter
1 Tbs. all-purpose flour
1 1/2 cups whole milk
8 oz. Monterey Jack cheese, coarsely grated (about 2 cups)
Kosher salt & freshly ground black pepper
Preheat oven to 375 degrees F.
Put the chile on a rimmed baking sheet, rub with 1 Tbs. of the oil, and season with salt & pepper. Roast in the oven until the skin on the chile is blackened, about 15-20 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 oz. each). Form each portion loosely into a 3/4"-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 Tbs. oil. (Click HERE for Bobby's cooking times for beef burgers.)
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 bun tops and serve immediately.
- We're trying to be a little healthier, so we used 1 lb. of 85/15 ground beef. The burgers were a little smaller and not quite as juicy, but with the queso sauce it wasn't a big deal.
- As with all of his burgers, we make the patties a bit thinner so they fit the buns we buy.
- We also use less oil because we cook in a nonstick skillet.
- We decided it would probably be a good idea to turn the chile halfway through the roasting time.
- The queso sauce is very mild but tastes great. Next time we might try mixing in some pepper jack cheese. The sauce is also great as a chip dip and would probably be good as fondue, too. (*Second time around: I like the queso sauce just the way it is, but a small amount of pepper jack would probably be good if you want more spice.)
