In a large pot of salted boiling water, cook the pasta according to package instructions until al dente. Drain and set aside.
In a large saucepan, heat the olive oil over medium heat. Add the minced garlic and chopped jalapeños, sautéing for about 2 minutes until fragrant.
Lower the heat and add the softened cream cheese, heavy cream, and half of the cheddar cheese to the saucepan. Stir until the cheese is melted and the sauce is smooth.
Add the grated Parmesan cheese, smoked paprika, salt, and pepper to the sauce. Mix well to combine.
Add the cooked pasta and optional chopped chicken to the sauce, stirring to coat the pasta evenly with the creamy mixture.
Top the pasta with the remaining cheddar cheese, mixing it in until melted and gooey.
Divide the pasta into bowls. Garnish with fresh cilantro or parsley for a pop of color and freshness.
Notes
Adjust jalapeño quantity based on spice preference.
