Cook the Pasta: Cook the pasta according to package directions until al dente. Reserve about 1 cup of pasta water before draining.

Sear the Chicken: Season the chicken pieces with salt and pepper. Heat the olive oil in a large skillet over medium-high heat. Add the chicken and cook until browned and cooked through, about 5-7 minutes. Remove the chicken from the skillet and set aside.

Sauté Aromatics: In the same skillet, add the chopped onion and cook until softened, about 3-4 minutes. Add the minced garlic and cook for another minute until fragrant.

Build the Sauce: Stir in the chopped sun-dried tomatoes and cook for 1-2 minutes. Pour in the chicken broth and scrape up any browned bits from the bottom of the skillet.

Create the Creamy Dream: Add the heavy cream and bring to a simmer. Reduce the heat to low and stir in the Parmesan cheese until melted and smooth. Season with red pepper flakes (if using), salt, and pepper to taste.

Combine and Simmer: Return the cooked chicken to the skillet. Add the cooked pasta to the sauce and toss to coat. If the sauce is too thick, add a little of the reserved pasta water until it reaches your desired consistency.

Finishing Touches: Stir in the fresh basil and oregano. Serve immediately, garnished with extra Parmesan cheese.
