In a bowl, toss chicken with 1 tbsp olive oil and season with garlic powder, onion powder, salt, pepper, and smoked paprika.
Heat the olive oil and butter in a large skillet over medium heat. Cook chicken until browned and cooked through. Remove and set aside.
In the same skillet, melt the remaining butter. Add carrots and onion; cook 7 minutes until soft. Stir in garlic and cook 1 minute more.
Stir in orzo and toast for 1 minute. Add bouillon and water, scraping the bottom of the pan. Stir in broccoli.
Bring to a boil, then cover and simmer for 11–12 minutes, until orzo is tender.
Stir in cream, cheddar, and Parmesan. Mix until melted and creamy.
Add chicken back to the pan. Stir to combine and serve hot.
Notes
Make Ahead, Storage & Freezing Tips
Make Ahead: You can chop the veggies and season the chicken ahead of time to save prep work.
Storage: Store leftovers in an airtight container in the fridge for up to 4 days.
Reheating: Reheat gently on the stovetop with a splash of milk or broth to loosen the sauce.
Freezing: This dish can be frozen, but keep in mind that creamy pasta dishes may change texture slightly after thawing. Freeze in a tightly sealed container for up to 2 months. Thaw overnight in the fridge and reheat as noted above.
