Step 1: Prepare the Chicken
Season the chicken breasts generously with salt and pepper on both sides.
Halving larger chicken breasts makes them cook faster and ensures even coating.
Set them aside while you prepare the crispy mixture.

Step 2: Make the Coating
In a shallow dish, mix the grated Parmesan cheese and panko breadcrumbs.
Press each chicken breast firmly into the mixture, coating both sides evenly.
This will help the crust become perfectly golden and crispy during cooking.

Step 3: Sear the Chicken
Heat olive oil in a large skillet over medium-high heat until shimmering.
Add the coated chicken and sear for 3–4 minutes per side until golden brown.
Transfer the chicken temporarily to a plate once both sides have a beautiful crust.

Step 4: Prepare the Sauce
Lower the heat to medium-low and add minced garlic to the skillet.
Sauté the garlic for about a minute, stirring constantly to avoid burning.
Pour in the cream, add Italian seasoning, and stir well to create a creamy base.

Step 5: Finish the Sauce
If using spinach, stir it into the sauce now and let it wilt for a minute or two.
Mix in the grated Parmesan cheese and let the sauce simmer gently until slightly thickened.
Taste and adjust seasoning if needed before returning the chicken to the skillet.

Step 6: Finish Cooking the Chicken
Nestle the seared chicken into the sauce and spoon a little sauce over the top.
Cover the skillet and cook for 8–10 minutes until the chicken reaches an internal temperature of 165°F.
Let everything simmer together to meld those incredible flavors.

Step 7: Serve
Plate each chicken breast and generously spoon over the creamy garlic sauce.
Garnish with extra Parmesan or fresh herbs if you like, and serve hot for a meal no one will forget.
