Ingredients
Method
- Mix. Combine cream cheese, mozzarella, chopped spinach, garlic, and Italian seasoning in a bowl. Season with salt and pepper.
- Butterfly. Cut a deep pocket into each chicken breast horizontally, slicing almost all the way through but not quite. Open it like a book.
- Stuff. Divide the filling evenly among the chicken breasts. Press the edges together and secure with toothpicks if needed.
- Sear. Heat olive oil and butter in a large oven-safe skillet over medium-high heat. Sear chicken 3 to 4 minutes per side until deeply golden. (Don’t move them too early.)
- Bake. Transfer the skillet to a 400°F oven and bake 15 to 18 minutes until chicken reaches 165°F internally. The cheese should be melted and bubbling at the seams.
- Serve. Rest for 5 minutes before slicing. Spoon any pan juices over the top.
Notes
Pound thick chicken breasts to an even 3/4 inch thickness before butterflying so they cook evenly. Soften the cream cheese fully or the filling will be lumpy and hard to spread. Don’t overstuff or the filling leaks out during searing. About 2 to 3 tablespoons per breast is plenty.
