This is a great quick meal. I always seem to have the ingredients on hand!
Portioning the soup and milk mixture requires precision before any assembly begins, reserving exactly four tablespoons to bind the dry chicken filling while the rest remains earmarked for the exterior coating. Combining canned cheese soup and dairy creates a pourable emulsion that hydrates the flour tortillas during baking, preventing them from turning tough or leathery in the heat. Whisking the soup thoroughly with the milk eliminates lumps before it contacts the aromatics.
Cubed cooked chicken breasts absorb flavors more evenly when tossed with salsa, green chiles, and chili powder while still warm, allowing the moisture from the salsa to penetrate the meat fibers. Rolling each tortilla tightly around this filling and arranging them seam-side down in a greased baking pan prevents the contents from escaping as the dish bubbles in the oven. Leaving a small amount of space between each roll ensures the sauce coats every surface.
Covering the pan with aluminum foil for the initial phase of baking at 375 degrees Fahrenheit traps steam, allowing the tortillas to soften completely before the top layer of dairy sauce thickens. Removing the cover during the final minutes promotes gentle browning without scorching the delicate milk solids in the sauce. A reliable oven thermometer verifies the 375 degree environment required for even heat distribution.
Adjusting this yield for larger gatherings simply requires doubling the filling components proportionally while maintaining the correct ratio of soup to milk for adequate coverage. Standard casserole dishes accommodate varying quantities easily when packed in orderly rows. Leftovers maintain proper texture when stored in an airtight container for up to three days.
