01 - Season both sides of the chicken breasts with salt, black pepper, and dried Italian herbs, pressing gently to help the seasoning adhere.
02 - Heat olive oil in a large skillet over medium-high heat until shimmering. Add chicken breasts and sear for 4-5 minutes per side until golden brown and cooked through to an internal temperature of 165°F. Transfer to a plate and cover loosely with aluminum foil to rest.
03 - Reduce heat to medium. In the same skillet, melt butter, then add minced garlic. Cook for 30 seconds until fragrant, being careful not to burn it.
04 - Add sun-dried tomatoes and dry orzo to the skillet, stirring constantly to coat the pasta and toast for 1 minute.
05 - Pour in chicken broth and heavy cream, stirring well and scraping up any browned bits from the bottom of the skillet to incorporate the fond.
06 - Add grated Parmesan cheese, red pepper flakes (if using), dried thyme, and a pinch each of salt and pepper. Stir until cheese melts and sauce begins to thicken slightly.
07 - Nestle the rested chicken breasts back into the skillet, cover with lid, and reduce heat to low. Simmer for 12-15 minutes, stirring orzo occasionally to prevent sticking. Add additional chicken broth one tablespoon at a time if the sauce becomes too thick. Cook until orzo is al dente and sauce is creamy.
08 - Remove skillet from heat and let rest uncovered for 2-3 minutes to allow sauce to thicken further. Garnish with chopped fresh basil and additional Parmesan cheese before serving.
