Can I use chicken breasts instead of thighs?
Yes, but thighs stay more moist during baking. If using breasts, reduce baking time by 5–10 minutes and check doneness at 160°F internal temperature to avoid drying out.
Can I make this ahead?
Assemble the dish in a baking dish, cover, and refrigerate up to 24 hours before baking. Add 5–10 minutes to bake time if starting from cold.
What type of green chiles should I use?
Mild canned diced green chiles (Hatch or standard) work best. For more heat, use jalapeños or a spicier variety, adjusting quantity to taste.
Can I substitute the cheese?
Monterey Jack, Oaxaca, or a mix of cheddar and Jack work well. Avoid low-moisture cheeses; the sauce needs a creamy melt.
How do I know when the chicken is done?
Internal temperature should reach 165°F in the thickest part. Thighs typically take 35–45 minutes at 375°F depending on size.
