1-Step 1: Prepare and Season the Chicken Start by patting your chicken breasts dry with paper towels. This crucial step ensures you get a beautiful golden sear rather than steaming the meat. If your chicken breasts are particularly thick, consider butterflying them or pounding them to an even thickness of about ½ inch for faster, more even cooking. Season both sides of each chicken breast generously with the Italian seasoning, salt, and freshly ground black pepper. Rub the seasonings in gently with your hands to help them adhere to the meat. The Italian seasoning blend typically contains oregano, thyme, basil, and rosemary, which will infuse the chicken with those classic Mediterranean flavors.

2-Step 2: Sear the Chicken to Golden Perfection Heat 2 tablespoons of olive oil in a large skillet over medium heat. Wait until the oil shimmers slightly, indicating it’s hot enough for searing. Carefully place the seasoned chicken breasts in the skillet, making sure not to overcrowd the pan. If your skillet is smaller, cook the chicken in two batches. Sear the chicken for 3 to 4 minutes per side until you see a beautiful golden-brown crust form. This browning, known as the Maillard reaction, creates incredible flavor depth. Once both sides are nicely golden and the chicken is cooked through, remove the chicken from the skillet and set it aside on a plate. The chicken doesn’t need to be fully cooked at this point since it will finish cooking in the sauce later.

3-Step 3: Build the Flavor Base Using the same skillet keeps all those flavorful browned bits from the chicken, which adds tremendous depth to your sauce. Add another tablespoon of olive oil to the skillet. Toss in the finely chopped yellow onion and sauté for 2 to 3 minutes until softened and translucent. Next, add the thinly sliced sun-dried tomatoes and minced garlic to the skillet. Cook for about 1 minute until the garlic becomes fragrant. Be careful not to burn the garlic, as it can turn bitter quickly. The sun-dried tomatoes will begin to release some of their oils and soften slightly, intensifying their sweet-tangy flavor.

4-Step 4: Create the Creamy Sauce Stir in the 2 cups of baby spinach and cook until it just begins to wilt, which should take about 30 seconds to 1 minute. The spinach will continue wilting in the hot sauce, so don’t overcook it at this stage. Pour in the 1 ½ cups of heavy cream and add the ¼ cup of freshly grated parmesan cheese. Stir everything together and bring the mixture to a gentle simmer. Let it bubble lightly for 2 to 3 minutes, which allows the sauce to reduce slightly and thicken. The parmesan will melt into the cream, creating a silky, luxurious texture. For extra depth of flavor, you can add a splash of white wine when sautéing the onions to deglaze the pan. This technique lifts all those delicious browned bits from the bottom of the skillet and incorporates them into your sauce.

5-Step 5: Finish and Serve Return the seared chicken breasts to the skillet, nestling them into the creamy sauce. Spoon some of the sauce over the chicken and let everything cook together for about 5 minutes until the chicken is heated through and fully cooked. The internal temperature should reach 165°F. Remove from heat and let the dish rest for a couple of minutes. The sauce will continue thickening as it cools slightly. Serve your Tuscan Chicken immediately while it’s hot and the sauce is at its creamiest.
