In a large skillet, melt 2 tablespoons butter over medium heat. Add onion and garlic; cook, stirring occasionally, for 4 minutes or until tender. Stir in spinach until wilted. Stir in all cheese until melted. Stir in bacon and next 4 ingredients; let cool completely.
Preheat oven to 400°. Line a large rimmed baking sheet with parchment paper.
In a small saucepan, melt remaining 1 cup butter. On a work surface, layer 4 sheets phyllo, brushing each sheet with melted butter (cover remaining phyllo with a damp towel to prevent drying). Place 1 chicken breast in center of layered phyllo. Spoon about ¼ cup spinach mixture in center of chicken. Fold chicken in half, covering spinach mixture. Fold layered phyllo over chicken to completely enclose, tucking ends of phyllo under chicken. Place seam side down on prepared pan, and brush top with melted butter. Repeat procedure with remaining phyllo, melted butter, chicken, and spinach mixture.
Bake for 25 minutes or until golden brown and chicken is done. Let stand for 5 minutes before serving.
