Bring a pot of salted water to a boil. Cook pasta according to package instructions until al dente. Drain and set aside.
While pasta cooks, heat olive oil in a large skillet over medium heat. Add onion and bell peppers. Sauté for about 4-5 minutes until softened.
Stir in garlic, chili powder, cumin, smoked paprika, salt, and pepper. Cook for another minute until fragrant.
Add shredded rotisserie chicken and mix well. Pour in the cream and bring it to a gentle simmer.
Stir in the Parmesan cheese and continue stirring until the sauce thickens slightly—about 3-4 minutes.
Toss in the cooked pasta and squeeze in fresh lime juice. Mix to coat everything evenly.
Sprinkle with chopped cilantro, if using. Serve warm with extra Parmesan if you’re feeling cheesy.
