01 - Pat the chicken breasts dry and season evenly on both sides with kosher salt, black pepper, and Italian seasoning.
02 - Heat olive oil in a large deep skillet over medium-high heat. Sear the chicken breasts for 3 to 4 minutes per side until a golden crust forms. Transfer to a plate and set aside—the chicken will finish cooking in the sauce.
03 - In the same skillet, add the minced garlic and chopped sun-dried tomatoes. Cook for about 1 minute, stirring constantly, until fragrant.
04 - Add the dry orzo to the skillet and stir to coat the pasta in the flavored oil. Toast for 1 minute, stirring frequently to prevent sticking.
05 - Pour in the chicken broth and heavy cream, stirring well to combine. Bring the mixture to a gentle simmer over medium heat.
06 - Nestle the seared chicken breasts back into the skillet, pressing them into the orzo mixture. Cover with a lid, reduce heat to medium-low, and cook for 10 to 12 minutes, stirring the orzo occasionally, until the pasta is al dente and the chicken reaches an internal temperature of 165°F.
07 - Remove the chicken breasts from the skillet and slice them against the grain. Stir the grated Parmesan cheese, red pepper flakes, and baby spinach into the orzo, mixing until the sauce is creamy and the spinach has wilted.
08 - Return the sliced chicken to the pan and gently toss to coat in the sauce. Garnish with fresh chopped basil and additional Parmesan cheese. Serve immediately.
