Step 1

Preheat your oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish.

Step 2

Pat the chicken breasts dry with paper towels, then season them with salt and pepper.

Step 3

Heat olive oil in a large oven-safe skillet over medium-high heat. Add the chicken breasts and sear them for 3-4 minutes on each side until they have a golden crust. Place them in the prepared baking dish.

Step 4

In a bowl, mix together the softened cream cheese, ranch seasoning mix, and sour cream or Greek yogurt until well combined.

Step 5

Spread the cream cheese mixture evenly over the seared chicken breasts in the baking dish. Sprinkle half of the cooked, chopped bacon on top of the cream cheese layer.

Step 6

Top with both the shredded cheddar and mozzarella cheeses.

Step 7

Place the baking dish in the preheated oven and bake for 20-25 minutes, or until the chicken is cooked through and the cheese is melted and bubbly. If desired, switch the oven to broil for the last 2-3 minutes to brown the cheese topping. Keep an eye on it to prevent burning.

Step 8

Remove the baking dish from the oven and let it rest for a few minutes before serving. Garnish with the remaining bacon, chopped green onions, and if using, fresh parsley.
