Season & Sear the Chicken: Pat chicken dry and season generously with salt and pepper.
Heat olive oil and butter in a large skillet over medium-high heat.
Sear chicken for 4–5 minutes per side until golden and cooked through (165°F internal). Remove and set aside.
Make the Lemon Cream Sauce: In the same skillet, add garlic and sauté for 30 seconds until fragrant.
Deglaze with chicken broth, scraping up browned bits.
Stir in cream, lemon juice, zest, Dijon, and Parmesan. Simmer 3–4 minutes until slightly thickened.
Combine: Return chicken to skillet, spoon sauce over the top, and simmer for 2 more minutes to meld flavors.
Finish & Serve: Garnish with fresh parsley and extra lemon zest.
Serve with mashed potatoes and roasted or steamed asparagus for a complete meal.
