Mix together salt, smoked paprika, rosemary, thyme, and parsley. Season both sides of chicken breasts with seasoning mixture.
Heat a skillet over medium heat. Drizzle with oil and add chicken breasts. Cook for 3 minutes and flip. Continue cooking for another 3 minutes, or until internal temperature reaches 165℉. Remove from skillet.
Using the same skillet, melt the butter. Add the garlic and cook until fragrant. Make sure to gently scrape the bottom of the pan in order to incorporate the flavorful brown bits.
Add the flour and whisk to incorporate with the butter.
Add half & half while whisking to avoid any clumping. Allow to simmer until it begins to thicken.
Add chicken broth and taste to see if salt is needed.
Return the chicken to the skillet. Give the chicken a couple of minutes to warm back up.
