Notes
Chicken Thigh Variation
You can substitute boneless, skinless chicken thighs for extra tenderness.
- Use 2½ lbs boneless skinless chicken thighs
- Sear 2 minutes per side (they brown quickly)
- Bake uncovered at 400°F for 20–22 minutes
- Broil only if additional browning is desired
- Avoid over-searing the chicken. It will finish cooking in the oven.
- Xanthan gum is optional and does not affect flavor.
- Freshly grated cheese melts more smoothly.
