Break up the ground beef into small, uniform pieces while cooking for better texture and even seasoning distribution.
Make the cheese sauce just before serving to prevent it from thickening too much or breaking.
Warm the taco shells in a 300°F oven for 2-3 minutes before filling to make them extra crispy.
Good to Know

Whisk in warm milk a tablespoon at a time until you reach the desired consistency. Heat gently while whisking to prevent lumps.
