Begin by bringing a large pot of salted water to a boil. Add the egg noodles and cook according to package instructions until al dente. Drain and set aside.
While the noodles are cooking, season both sides of the chicken breasts with salt, pepper, paprika, and thyme.
In a large skillet, heat the olive oil over medium-high heat. Once hot, add the chicken breasts and cook for about 6-7 minutes on each side until golden brown and cooked through. Remove the chicken from the skillet and set aside to rest.
In the same skillet, add the butter. Once melted, add the minced garlic and sauté for about 1 minute until fragrant.
Pour in the chicken broth, scraping the bottom of the pan to deglaze and incorporate any flavorful bits. Bring to a simmer. Then, stir in the heavy cream and cook for 3-5 minutes until the mixture thickens slightly.
Slice the cooked chicken and return it to the skillet with the sauce. Add the drained noodles to the skillet as well, tossing everything together until the noodles are well coated in the creamy sauce.
Taste the mixture and adjust seasoning with more salt and pepper if necessary.
Plate the creamy garlic chicken and buttered noodles, garnishing with chopped fresh parsley and grated Parmesan cheese if desired.
