Gather ingredients. Preheat the oven to 350 degrees F (175 degrees C).

Place chicken breasts on a flat work surface. Slice horizontally through the middle, being careful not to cut all the way through to the other side. Open the 2 sides and spread them out like an open book to butterfly.

Melt butter in a large, oven-safe skillet over medium-high heat. Add garlic, oregano, thyme. Sauté until fragrant, about 30 seconds.

Add chicken and cook until golden brown but not fully cooked, 3 to 4 minutes per side.

Pour 1/4 cup chicken broth into the skillet and bake in the preheated oven until chicken is no longer pink in the center and juices run clear, about 15 minutes. An instant-read thermometer inserted into the thickest part should read at least 165 degrees F (74 degrees C).

Meanwhile, place bacon in a large skillet and cook over medium-high heat, turning occasionally, until evenly browned, about 10 minutes. Drain bacon slices on paper towels and let cool enough to handle, about 5 minutes; chop.

At the same time, bring a large pot of lightly salted water to a boil. Cook angel hair pasta in the boiling water, stirring occasionally, until tender yet firm to the bite, 4 to 5 minutes. Drain and keep warm.

Remove skillet from the oven and transfer chicken to a plate, reserving juices in the skillet. Cover chicken with foil to keep warm and place skillet on the stovetop.

Whisk flour into the skillet over medium heat. Add remaining chicken broth, Parmesan cheese, and whipping cream. Whisk until combined and flour is no longer raw, about 3 minutes.

Add sun-dried tomatoes, red pepper flakes, and salt. Add bacon and chicken back into the skillet.

Serve on top of hot cooked pasta.
