Golden pan-seared chicken breasts stuffed with melty fontina cheese and simmered in a rich Marsala mushroom cream sauce. An elegant Italian-American dinner ready in just 40 minutes with 58g of protein per serving.
4 oz fontina cheese, cut into 4 equal 1-oz pieces (or provolone, Gruyere, or low-moisture mozzarella)
2 tablespoons olive oil
2 tablespoons unsalted butter, divided
Salt and pepper, to taste
8 oz cremini mushrooms, sliced
1/2 small onion, sliced
3/4 cup dry Marsala wine (or dry sherry, Madeira, or equal parts balsamic vinegar and white grape juice for non-alcoholic)
1/2 cup chicken stock
1/4 cup heavy cream, at room temperature
Chopped fresh parsley, optional for garnish
Instructions
Using a sharp paring knife, cut a small slit in the thickest part of each chicken breast. Push the knife horizontally to create a deep pocket sealed on three sides. Do not cut through the sides or bottom.
Stuff each breast with one 1-oz piece of fontina cheese. Do not overstuff. Press the opening closed firmly with your fingers.
Heat a large skillet over medium heat. Add olive oil and 1 tablespoon butter. Season chicken generously with salt and pepper on both sides.
Add chicken to the hot skillet. Sear without moving for 5 to 6 minutes until deeply golden brown. Flip and sear the second side for another 5 to 6 minutes. Remove chicken and set aside – it does not need to be fully cooked at this stage.
Add remaining 1 tablespoon butter to the same skillet. Add sliced mushrooms and onion. Saute for 5 to 6 minutes until softened and lightly browned.
Pour in the dry Marsala wine. Bring to a boil then reduce to a simmer. Simmer for 2 to 3 minutes until slightly reduced.
Stir in chicken stock and room-temperature heavy cream. Bring back to a gentle simmer.
Return stuffed chicken breasts to the skillet, nestling them into the sauce. Cover and simmer for 6 to 7 minutes until chicken reaches 165 degrees F internally and the fontina inside is fully melted.
Season sauce with salt and pepper to taste. Garnish with fresh parsley and serve immediately over mashed potatoes or pasta.
Notes
Always use dry Marsala wine, never sweet – sweet Marsala produces an overly sugary sauce that does not match the classic savory flavor profile.
Bring heavy cream to room temperature before adding to the pan – cold cream in a hot pan is much more likely to curdle and break the sauce.
Stuffed chicken breasts can be prepped and refrigerated up to 12 hours ahead. Let them rest at room temperature for 20 to 30 minutes before searing.
Freezing is not recommended – the cream sauce separates significantly after thawing.
