01 - Season the chicken pieces with paprika, salt, and black pepper, ensuring even coating on all sides.
02 - Heat 1 tablespoon butter in a large skillet over medium-high heat. Sauté the chicken until golden brown and cooked through, approximately 5–6 minutes. Remove chicken to a plate and set aside.
03 - Reduce heat to medium. Melt remaining butter in the skillet. Add garlic and onion, sautéing until fragrant and translucent, about 2–3 minutes.
04 - Stir in orzo pasta, toasting lightly for 1 minute to develop nutty flavor. Pour in chicken broth and milk, stirring constantly and scraping up any browned bits from the bottom of the skillet.
05 - Bring mixture to a gentle simmer. Cook uncovered, stirring occasionally to prevent sticking, for 8–10 minutes until orzo is mostly tender and most of the liquid has been absorbed.
06 - Stir in heavy cream and cooked chicken. Add spinach and Pepper Jack cheese, stirring continuously until spinach wilts and cheese melts completely, 2–3 minutes.
07 - Taste and adjust seasoning as needed. Sprinkle with fresh parsley and serve immediately with lemon wedges on the side.
