Prepare the Chicken: Begin by heating the olive oil in a large skillet or pot over medium-high heat. While the oil is heating, season both sides of the chicken thighs generously with salt and pepper.
Sear the Chicken: Once the oil is shimmering, carefully add the seasoned chicken thighs to the skillet. Sear them for approximately 5 minutes on each side until they develop a golden brown crust and are completely cooked through. After cooking, remove the chicken from the pot and set it aside on a plate.
Sauté the Garlic: In the same skillet, lower the heat slightly and add the minced garlic. Sauté for about 30 seconds, stirring constantly until the garlic is fragrant but not burned.
Add Tomatoes: Toss the halved cherry tomatoes into the pot and cook them for about 3-4 minutes, allowing them to soften and release their juices.
Incorporate Spinach: Next, fold in the fresh spinach and cook for another 2 minutes until it wilts down and reduces in volume.
Create the Sauce: Reduce the heat to low and slowly pour in the heavy cream, stirring gently to combine all the ingredients evenly.
Season the Sauce: Sprinkle in the Italian seasoning and stir in the grated Parmesan cheese. Allow the sauce to simmer slightly, thickening as the cheese melts and integrates with the cream.
Combine Chicken and Sauce: Return the seared chicken thighs to the pot, nestling them in the creamy sauce. Spoon some sauce over each piece, and let everything simmer together for an additional 5 minutes, allowing the flavors to meld beautifully.
Serve and Garnish: To finish, transfer the creamy Tuscan chicken to a serving platter or individual plates. Garnish with fresh basil leaves for a burst of color and flavor before serving.
Notes
For an elevated touch, serve with a side of garlic bread or over a bed of fluffy rice or pasta.
