This deceptively indulgent one-pot creamy chicken pasta uses homemade chicken broth and pasta starch to create a naturally creamy sauce with just a touch of cream. Loaded with tender chicken, fresh vegetables, and perfectly cooked pasta, it's a complete meal that's ready in 30 minutes with minimal cleanup required.
Heat the broth: Bring chicken broth to a boil in a medium saucepan and keep warm.
Brown the chicken: Heat oil in a large sauté pan with lid over medium-high heat. Add cubed chicken, season with salt and pepper, and cook 8-10 minutes until golden brown on all sides.
Add vegetables: Add onion, garlic, carrots, celery, oregano, salt, and pepper. Stir and cook 1 minute until fragrant.
Combine pasta and broth: Add hot chicken broth and dry pasta to the pan. Stir well, bring to a boil, then reduce to a simmer.
Cook pasta: Cover and simmer 8 minutes, stirring occasionally, until pasta is just shy of al dente.
Add broccoli: Stir in broccoli florets. Whisk cornstarch into heavy cream until smooth, then stir into the pan.
Finish and rest: Return to a simmer and cook 1 minute. Remove from heat and let rest uncovered for 5 minutes.
Serve: Garnish with parsley and Parmesan cheese if desired.
