Bring a large pot of salted water to a boil. Wash and dry produce.
Trim, peel, and finely chop carrot.
Pick parsley leaves from stems; roughly chop leaves.
Once the water is boiling, add cavatappi to the pot.
Cook, stirring occasionally, until al dente, between 9-11 minutes. Drain.
While cavatappi cooks, heat a drizzle of oil in a large pan over medium heat. Add carrot; cook, stirring, until browned and tender, 6-8 minutes.
Season with salt and pepper.
Increase heat under pan with carrot to medium-high and add a drizzle of oil. Push the carrot to one side of the pan and add beef to the empty side. Cook, breaking up meat into pieces until browned.
Sprinkle with Italian seasoning. Cook, stirring, until beef is cooked through, 4-6 minutes. Season generously with salt and pepper.
Stir carrot and beef to combine.
Stir in marinara and 1⁄3 cup water (½ cup for 4 servings).
Reduce to a simmer and cook until sauce has slightly thickened 3-4 minutes.
Reduce heat to low.
Stir in cream cheese until thoroughly combined.
Add drained cavatappi, 1 tbsp butter, and half the chopped parsley; stir until pasta is warmed through, 1-2 minutes.
Season with salt and pepper.
Divide pasta between bowls.
Top with Parmesan and remaining chopped parsley.
