01 - Pat the chicken breasts dry and season both sides evenly 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 golden brown. 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 1 minute, stirring constantly, until fragrant.
04 - Add the dry orzo pasta to the skillet and stir to coat it 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 down into the orzo mixture. Cover with a lid and cook over medium-low heat for 10 to 12 minutes, stirring occasionally, until the orzo 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 until the cheese melts and the spinach wilts.
08 - Return the sliced chicken to the skillet and gently toss everything together. Garnish with fresh basil and additional Parmesan cheese. Serve immediately while hot.
