Begin by heating a large skillet over medium heat. Drizzle in the olive oil and allow it to heat until shimmering but not smoking.
While the oil warms, season both sides of the chicken breasts generously with salt, black pepper, and the Italian seasoning, ensuring an even distribution.
Once the oil is hot, gently place the seasoned chicken breasts into the skillet. Sear the chicken for approximately 6-7 minutes on each side, or until they are golden brown and cooked through (the internal temperature should reach 165°F/75°C). Once done, transfer the chicken to a plate and set aside.
In the same skillet, reduce the heat slightly, then add the minced garlic. Sauté for about 30 seconds, stirring constantly, until it becomes aromatic and golden, taking care not to let it burn.
Next, incorporate the halved cherry tomatoes into the skillet. Cook them for an additional 2-3 minutes, stirring occasionally, until they begin to soften and burst.
Stir in the fresh spinach, cooking until just wilted—this should take about 1-2 minutes.
Pour in the heavy cream, increasing the heat to bring the mixture to a gentle simmer. Stir continuously to help prevent the cream from scorching on the bottom of the skillet.
Gradually sprinkle in the grated Parmesan cheese and squeeze the lemon juice into the sauce. Mix thoroughly until the cheese has melted completely, integrating it into a rich, creamy sauce.
Return the chicken breasts to the skillet, nestling them in the sauce. Spoon some of the creamy mixture over the tops of the chicken and let it simmer for an additional 2-3 minutes, allowing the flavors to meld beautifully.
To finish, garnish your dish with fresh basil leaves for a pop of color and aroma just before serving.
