In a small bowl, combine all seasoning mixture ingredients. Coat the chicken cutlets with about a tbsp of olive oil. Evenly sprinkle the seasoning mixture on both sides of the chicken until well coated.
Heat the other tbsp of olive oil in a large high-rimmed sauté pan over medium-high heat. Add the seasoned chicken cutlets and cook for about 4 minutes a side. Set aside on a plate. The chicken does'nt need to be fully cooked yet because it will get cooked through later.
In the same pan, melt the butter over medium heat. Add the onions and cook for 3 minutes until fragrant. Add the garlic and cook another minute, stirring often. Add the uncooked orzo and toast for a minute, stirring often.
Pour in the white wine to deglaze the pan. Scrape up the brown bits from the bottom of the pan with a wooden spoon.
Pour in the chicken broth and marinara sauce. Bring to a boil then lower the heat. and simmer for a few minutes, stirring often so the orzo doesn't stick to the bottom of the pan. Add back the chicken, cover the pan, and cook until the orzo is cooked through. Every few minutes, give the orzo a stir to prevent sticking. Add more chicken broth if the liquid is absorbed before the orzo is fully cooked.
Once the orzo is cooked, tear the burrata into pieces and place on top of the chicken and orzo. Scatter the fresh basil on top as well. Cover and cook for another 2 minutes until the burrata is melted. Serve immediately.
