How do I butterfly a chicken breast without it falling apart?
Place the breast on a cutting board, place your hand flat on top, then carefully cut horizontally through the thickest part, leaving about 1/2 inch attached on one side so it opens like a book. Keep your knife parallel to the board for an even thickness.
Can I make this ahead of time?
Yes. Stuff the chicken up to 4 hours ahead, cover with plastic wrap, and refrigerate. Add 5-10 minutes to the baking time if cooking from cold. The finished dish can be refrigerated for 3 days and reheated gently in a 350°F oven.
How do I know when the chicken is fully cooked?
Use an instant-read thermometer inserted into the thickest part of the chicken (not touching the filling): it should reach 165°F. The juices should run clear when pierced.
What can I substitute for heavy cream?
Use half-and-half (slightly thinner sauce), Greek yogurt (tangier), or a mixture of milk and butter. Coconut cream works for dairy-free.
Can I double this recipe?
Yes. Double all ingredients but increase baking time by 5-10 minutes, depending on the thickness of your chicken breasts. Ensure sauce simmers long enough to reduce and thicken.
