Season the Chicken: Pat the chicken dry. In a small bowl, mix garlic powder, paprika, onion powder, thyme, salt, and pepper. Rub the seasoning all over the chicken.
Cook the Chicken: Heat olive oil in a skillet over medium-high heat. Add butter once the pan is hot. Add the chicken and sear 5–6 minutes per side (depending on thickness) until golden brown and cooked through (internal temp 165°F). Let it rest for a few minutes before slicing.
Cook the Noodles: Boil noodles in salted water until al dente. Reserve 1/4 cup of pasta water before draining. In the same pot or a skillet, melt butter over low heat. Add garlic (if using) and cook for 30 seconds until fragrant. Toss in the drained noodles, reserved pasta water, herbs, salt, pepper, Italian seasoning and Parmesan cheese. Stir until glossy.
Serve: Plate the buttered noodles. Slice the chicken and lay on top. Garnish with extra herbs, a drizzle of olive oil, or more Parmesan if desired.
