# Directions:

01 - Bring a large pot of salted water to boil. Cook spaghettini according to package instructions until al dente. Reserve 1/2 cup pasta water, then drain and set aside.
02 - While pasta cooks, pound chicken breasts to even thickness. Season both sides with salt and pepper.
03 - Heat olive oil in large nonstick skillet over medium-high heat. Add chicken breasts and cook 5-6 minutes per side until golden and cooked through. Remove to plate, cover loosely, and let rest.
04 - In same skillet, reduce heat to medium. Add mushrooms and onion; sauté 4-5 minutes until softened and golden. Add garlic and thyme, cook for 1 minute.
05 - Sprinkle flour over vegetables and stir well. Cook for 1 minute.
06 - Gradually whisk in chicken broth, followed by milk, stirring to avoid lumps. Bring to gentle simmer and cook 2-3 minutes until slightly thickened.
07 - Add Parmesan cheese and Dijon mustard; stir until smooth. Season with salt and pepper. Add spinach if using and stir until wilted.
08 - Slice chicken into strips. Add cooked spaghettini and chicken to sauce; toss gently to coat. Add splash of reserved pasta water if needed for desired sauce consistency.
09 - Plate immediately and garnish with fresh parsley and extra Parmesan if desired.

# Expert Tips:

01 -
  • The sauce tastes decadent but uses just enough milk to keep it light
  • Everything happens in one skillet which means less cleanup later
  • It comes together in under 40 minutes even on busy weeknights
02 -
  • Reserving pasta water is nonnegotiable as the starchy liquid binds the sauce to the pasta
  • Let the chicken rest for a few minutes before slicing or all those juices will escape onto the cutting board
03 -
  • Warm your milk slightly before adding it to prevent the sauce from breaking
  • Grate your own Parmesan fresh from the wedge for the smoothest melting texture
