In a large deep skillet, heat the olive oil over medium heat.
Add the chicken breast cubes and season generously with salt and pepper. Cook for 3-4 minutes, stirring occasionally, until they are nice and browned but not cooked through.
Add in the butter, onion and garlic and stir for 2-3 minutes. Add in the rice, chicken broth, salt, pepper, paprika, garlic powder, and stir.
Bring to a boil over high heat, then lower the heat to medium low. Cover and cook for 10 minutes.
Add in the broccoli florets, stir, then cover and cook for an additional 8-10 minutes until the rice is cooked and the broccoli is tender. Turn the heat to low.
Stir in the milk, dijon mustard, Greek yogurt, shredded cheddar, and parmesan until creamy.
Top with the remaining shredded cheese and cover until melted. Serve topped with fresh parsley if desired. Enjoy!
