- ¼ cup dry sherry wine
- 3 tablespoons all-purpose flour
- 1 cup chicken stock

Instructions

- Step 5: Preheat the oven to 375°F.
- Step 6: Dredge each chicken piece a second time in the seasoned flour and set back on the plate, then discard this flour.
- Step 7: In a large sauté pan, melt half the butter with half the olive oil over medium-high heat.
- Step 8: Brown four pieces of chicken on both sides, about 2-3 minutes per side, then transfer to the casserole dish.

- Step 19: Spray one side of a piece of parchment paper with non-stick spray and place it sprayed-side-down over the cheese. Cover the dish with foil and bake for 20 minutes.
- Step 20: Remove foil and parchment, then broil to brown the cheese topping. Serve warm.
Tips & Variations
- Butterflying the chicken helps it cook evenly and stay tender.
- Use dry sherry for best flavor, but a splash of dry white wine or apple cider vinegar can work in a pinch.
- For a richer sauce, use half-and-half instead of heavy cream to lighten it up.
- Try substituting Gouda or Havarti cheese if Muenster isn’t available.
- Cooking onions until just softened keeps a subtle sweetness without overpowering the dish.
Storage
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through. The sauce may thicken when chilled, so stir in a splash of chicken stock or cream if needed when reheating.
