Prepare the Chicken: Slice the chicken breasts horizontally to create thinner cutlets for quicker cooking. Season both sides with salt, pepper, and Italian seasoning.
Sear the Chicken: In a large skillet, heat 1 tablespoon of olive oil over medium-high heat. Add the chicken cutlets to the skillet and cook for about 4-5 minutes on each side, or until golden brown and cooked through. Remove the chicken from the skillet and set aside.
Sauté Aromatics: In the same skillet, add the remaining tablespoon of olive oil. Add diced onion and minced garlic. Sauté for 2-3 minutes until they become fragrant and translucent.
Cook Tomatoes and Spinach: Add the halved cherry tomatoes to the skillet. Cook for an additional 3-4 minutes until they start to blister. Stir in the spinach and cook until just wilted (if using fresh) or heated through (if frozen).
Add Cream and Broth: Pour in the chicken broth and heavy cream. Stir to combine, then bring to a gentle simmer. Add red pepper flakes and adjust seasoning with more salt and pepper as needed.
Reintroduce Chicken: Return the cooked chicken to the skillet, allowing it to sear lightly in the creamy sauce for about 2 minutes to soak up the flavors.
Garnish & Serve: Once everything is heated through, remove from heat. Garnish with chopped fresh basil and grated Parmesan cheese before serving.
Notes
Adjust the red pepper flakes to taste for desired spice level.
