Step 1: Prepare the Chicken
Season chicken breasts with salt, pepper, and a pinch of Italian seasoning. If desired, lightly dredge in flour for a golden crust.
Step 2: Sear the Chicken
Heat olive oil and butter in a large skillet over medium heat. Add chicken and sear for 5-6 minutes per side until golden brown. Remove chicken from skillet and set aside.
Step 3: Sauté the Garlic
Lower heat to medium-low. In the same skillet, add minced garlic and sauté for about 1 minute until fragrant. Be careful not to burn it.
Step 4: Deglaze the Pan
Pour in chicken broth and scrape up any browned bits from the bottom of the pan. This adds incredible flavor to your sauce.
Step 5: Create the Cream Sauce
Stir in heavy cream, lemon juice, lemon zest, and Italian seasoning. Bring to a gentle simmer. Taste and adjust seasoning with salt and pepper.
Step 6: Finish the Chicken
Return the seared chicken to the skillet, spooning sauce over each piece. Simmer for 5-8 minutes until chicken reaches an internal temperature of 165°F and sauce has thickened.
Step 7: Add Final Touches
If using, stir in Parmesan cheese and spinach during the last 2 minutes of cooking. The spinach will wilt beautifully into the sauce.
Step 8: Garnish and Serve
Remove from heat, sprinkle with fresh parsley, and serve immediately over pasta, rice, mashed potatoes, or your favorite side.
