Can I use bone-in chicken thighs instead of boneless breasts?
Yes, but increase baking time by 10–15 minutes and check that thighs reach 165°F at the thickest part. Thighs will stay moister than breast meat.
What if I don't have Chardonnay?
Any dry white wine (Pinot Grigio, Sauvignon Blanc) works; skip wine entirely and add 1/3 cup chicken broth if you prefer no alcohol.
Can I prep this ahead?
Yes. Assemble in the baking dish, cover, and refrigerate up to 24 hours. Add 5–10 minutes to baking time if starting from cold.
How do I know when the chicken is done?
Chicken is safe at 165°F internal temperature; use a meat thermometer inserted into the thickest breast. Avoid cutting into it, which lets juices escape.
Can this recipe be halved?
Yes. Use 1 lb chicken, 1/2 can soup, 2–3 tbsp wine, 1/2 cup mayo, and 1/2 cup cheese. Reduce baking time by 5–10 minutes.
