In a large skillet or Dutch oven, heat the olive oil over medium-high heat.
In a separate bowl, whisk together the lemon juice, garlic, rosemary, thyme, salt, and pepper.
Add the chicken breasts to the skillet and cook for 5-6 minutes per side, or until cooked through.
Remove the chicken from the skillet and set aside.
Add the butter to the skillet and let it melt.
Pour in the chicken broth and bring the mixture to a simmer.
Add the cooked chicken back into the skillet and spoon some of the lemon butter sauce over the top of each breast.
Cover the skillet and let it simmer for 10-15 minutes, or until the sauce has thickened and the chicken is fully coated.
Serve the chicken with a side of mashed potatoes and steamed broccoli, if desired.
