Creating One Pot Chicken Fajita Pasta is simple. Follow these easy steps:

1. Heat Oil: In a large pot or Dutch oven, heat olive oil over medium heat.
2. Cook Chicken: Add the diced chicken to the pot and cook until browned, about 5-7 minutes. Remove the chicken and set aside.
3. Sauté Vegetables: In the same pot, add sliced onions and bell peppers. Sauté until softened, about 5 minutes.
4. Add Garlic and Spices: Stir in the minced garlic, chili powder, cumin, smoked paprika, salt, and pepper. Cook for an additional 1-2 minutes until fragrant.
5. Combine Ingredients: Return the cooked chicken to the pot. Pour in the chicken broth and heavy cream, stirring to combine.
6. Add Pasta: Add the penne pasta to the pot and bring the mixture to a boil. Reduce heat to low, cover, and simmer until the pasta is cooked, about 12-15 minutes.
7. Stir in Cheese: Once the pasta is tender, remove the pot from heat and stir in the shredded cheese until melted and creamy.
8. Garnish: Serve hot, garnished with fresh cilantro and lime wedges if desired.
