Our healthier version of chile con queso will have ooey-gooey-cheese lovers celebrating. Now you can enjoy this Tex-Mex dip without all the fat and calories. We replaced some of the cheese with a low-fat white sauce and used sharp Cheddar plus a splash of beer to boost the flavor. Our version cuts the calories in half and reduces total fat and saturated fat by nearly 60 percent.
Heat oil in a large saucepan over medium heat. Add onion and garlic and cook, stirring, until soft and beginning to brown, 4 to 5 minutes. Add beer and cook until reduced slightly, about 1 minute. Add 1 cup milk and bring to a simmer.
Meanwhile, whisk the remaining 1/2 cup milk and cornstarch in a small bowl. Add to the pan and cook, stirring vigorously, until bubbling and thickened, 1 to 2 minutes. Reduce heat to low, add cheese and cook, stirring, until melted. Stir in drained tomatoes, lime juice, salt, chili powder and cayenne (if using). Serve warm, garnished with scallions and cilantro.
