01 - Evenly coat chicken cubes with paprika, salt, and black pepper, ensuring all pieces are thoroughly seasoned.
02 - Heat 1 tablespoon butter in a large skillet over medium-high heat. Cook chicken until golden brown and cooked through, approximately 5–6 minutes. Transfer to a plate and set aside.
03 - Reduce heat to medium. Melt remaining butter in the skillet. Add garlic and onion, cooking until fragrant and translucent, about 2–3 minutes.
04 - Stir orzo into the skillet, toasting lightly for 1 minute to enhance nutty flavor.
05 - Pour in chicken broth and whole milk, stirring continuously to deglaze the skillet and incorporate any browned bits from the bottom.
06 - Bring mixture to a gentle simmer. Cook uncovered for 8–10 minutes, stirring occasionally, until orzo is tender and most liquid has been absorbed.
07 - Stir in heavy cream and cooked chicken. Add spinach and Pepper Jack cheese, stirring until spinach wilts and cheese melts completely, 2–3 minutes.
08 - Taste and adjust seasoning as desired. Sprinkle with fresh parsley and serve immediately with lemon wedges on the side.
