Start by heating olive oil over medium-high heat in a large skillet. Season the chicken breasts with salt, pepper, and oregano, then sear until golden brown on both sides.

Using the same skillet, add garlic, chicken broth, heavy cream, Parmesan cheese, sun-dried tomatoes, and red pepper flakes. Let it simmer, stirring occasionally, until the sauce thickens.

While the sauce simmers, cook the pasta according to the package instructions. Once cooked, drain the pasta and set aside.

Add the cooked chicken back into the skillet and allow it to simmer in the sauce for a few minutes. Then, toss in the pasta, coating it evenly in the sumptuous sauce. Garnish with fresh basil for a fragrant finish.
