Start by seasoning your chicken breasts with salt and pepper. Heat the olive oil in a large skillet over medium heat. Once the oil is hot, add the chicken and cook until golden on both sides, about 4-5 minutes per side. You don’t need to cook it all the way through yet—it’ll finish cooking in the sauce. Remove the chicken from the skillet and set it aside.
Step 2: Make the Sauce
In the same skillet, toss in your minced garlic and cook for about 30 seconds until it’s fragrant (there’s nothing better than the smell of garlic cooking, right?). Add the sun-dried tomatoes and stir for another minute.
Pour in the chicken broth to deglaze the pan, scraping up all those tasty browned bits. Then stir in the heavy cream, Parmesan cheese, oregano, and red pepper flakes. Let it simmer for about 5 minutes, stirring occasionally, until the sauce starts to thicken.
