Step 1: Cook the Chicken
Season both sides of the chicken breasts with salt and pepper. Heat 1 tablespoon of olive oil and 1 tablespoon of butter in a large skillet over medium-high heat. Once the butter is melted and the pan is hot, add the chicken breasts. Sear them for about 5-7 minutes per side, or until golden brown and cooked through (internal temperature should reach 165°F). Remove the chicken from the skillet and set aside.

Step 2: Make the Creamed Spinach
In the same skillet, melt another tablespoon of butter over medium heat. Add the chopped onion and sauté for about 3-4 minutes until softened and translucent. Add the garlic and cook for another 30 seconds, until fragrant.

Add the spinach to the pan, stirring until it wilts (if using fresh spinach) or heats through (if using frozen spinach). If you’re using fresh spinach, it may look like a lot at first, but it wilts down significantly.

Step 3: Add the Creamy Goodness
Once the spinach is cooked down, pour in the heavy cream and stir to combine. Add the grated Parmesan cheese and cream cheese (if using), and let it all melt together, creating a rich, creamy sauce. Stir in a pinch of nutmeg (if using) and season with salt and pepper to taste. Let the sauce simmer for about 3-4 minutes until it thickens up.

Step 4: Smother the Chicken
Place the cooked chicken breasts back into the skillet, spooning the creamy spinach sauce over the top. Let everything simmer together for another 5 minutes to allow the chicken to absorb all that creamy goodness.

Step 5: Serve and Enjoy
Once everything is well coated and hot, it’s time to serve! Spoon extra creamed spinach on the chicken and drizzle with the rich sauce. Serve it over mashed potatoes, rice, or a bed of sautéed vegetables for the ultimate comfort meal.
