FAQ

Can I use frozen chicken breasts?

Thaw completely first and pat very dry. Frozen chicken will release excess moisture and make the cream sauce watery.

What if I don't have Swiss cheese?

Gruyere, provolone, or even mozzarella work well. Avoid hard cheeses that don't melt smoothly.

How long will leftovers keep?

Store covered in refrigerator up to 3 days. Reheat gently in oven at 300F to prevent cream sauce from separating.
