Begin by tenderizing the chicken breasts to an even thickness using a meat mallet. This helps them cook evenly.
Season both sides of the chicken breasts with salt, pepper, and dried thyme. After seasoning, dust each chicken breast lightly in flour, shaking off the excess.
In a large skillet, heat the olive oil over medium-high heat. Once the oil is hot, add the chicken breasts to the pan and sauté for about 5-6 minutes on each side, or until golden brown and cooked through. Remove the chicken from the skillet and set aside.
In the same skillet, add the butter. When melted, add the minced garlic and sliced mushrooms. Sauté for around 4-5 minutes or until the mushrooms are tender and browned.
Pour in the chicken broth and bring to a simmer, scraping any brown bits from the bottom of the skillet. Allow the broth to reduce slightly, about 3-4 minutes.
Lower the heat, then stir in the heavy cream, mixing thoroughly until the sauce is creamy and smooth.
Return the cooked chicken breasts to the skillet, spooning the creamy sauce over them. Simmer for an additional 2-3 minutes to heat through and meld flavors.
Taste the sauce and adjust seasoning with more salt and pepper if needed.
Once ready, serve the chicken with the creamy mushroom sauce drizzled over the top. Garnish with fresh parsley for added flavor and color.
Notes
