Pat the chicken pieces dry and season liberally on both sides with black pepper, kosher salt, and smoked paprika.
Heat oil in a large skillet over medium-high. Sear chicken 4–5 minutes per side; remove to a plate.
Spoon off any excess fat, leaving about 2 tablespoons.Sauté onions until soft; add garlic and cook 1 min.
Stir in orzo; cook 2–3 minutes to toast. Add stock, half and half, lemon zest, and feta. Bring to a low simmer.Return chicken and juices to skillet.
Cover and cook on low about 20 minutes, stirring the orzo off the bottom of the pan every 5-7 minutes during the process, until orzo is al dente and the chicken is fully cooked. (Internal temp of chicken should be 165℉ / 75℃).
Turn off the heat, remove the lid, and stir in half the chopped arugula. Cover again and let steep 20–30 min before serving.
Notes
Adjust the liquid to your liking. Want it saucier? Add a splash more broth. Prefer it thicker? Let it simmer a bit longer.
Switch up the chicken cut. Thighs stay extra juicy, but breasts will work, too; however, you will need to adjust the cooking time.
Want to speed things up? Use cubed chicken instead.
