Step 2

Melt butter in a medium saucepan over medium heat; add chiles and onion and cook 5 minutes. Add garlic and cook 1 minute longer; whisk in flour and cook for 30 seconds. While whisking, pour in milk and continue to cook until sauce is thick, about 3 minutes. Stir in tomatoes and cilantro and reduce heat to medium-low. Slowly add in cheeses, 1⁄2 cup at a time, until it has completely melted. Stir in sour cream and salt and serve with tortilla chips.
