Pat chicken thighs dry with a paper towel. Season the chicken with garlic powder, onion powder, kosher salt and black pepper. Toss to make sure chicken is well coated on both sides.
In a large nonstick skillet, warm 2 tbsp of oil over medium high heat. Place chicken thighs skin side down in the hot oil and cook for 6 minutes. Flip and cook for another 5 minutes. Skin side should be crispy and golden. Remove thighs from the skillet and set aside. Chicken will not be fully cooked at this point!
To the same pan, add 2 more tbsp of olive oil and sauté onion until they start to soften. Add orzo and toast over medium high heat for 3-4 minutes. Add minced garlic and cook for another 30 seconds. Stir in chicken broth and bring to a boil.
Return chicken thighs to the skillet. Reduce heat to medium low and let simmer, covered for 8 minutes. When finished, layer of broccoli over chicken and orzo and recover. Cook for 12 minutes or until chicken thighs reach 165℉ and the broccoli is tender.
Remove chicken thighs from skillet. Stir in shredded cheese, season to taste, and serve!
