Chicken:

2. Heat a skillet over medium heat and add olive oil.
3. Cook chicken for 8–10 minutes, flipping halfway, until golden brown and fully cooked (internal temperature 165°F). Remove and tent with foil to keep warm.

Pasta:

2. Reserve 1 cup of pasta water and drain the rest.

Garlic Butter Sauce:

1. Melt butter in the same pot over medium heat. Stir in chicken bouillon powder.
2. Add minced garlic and cook for 1 minute. Stir in ½ cup reserved pasta water to create a smooth sauce.

Combine and Serve:

1. Toss pasta in the garlic butter sauce and stir in parmesan cheese. Add more pasta water as needed to achieve desired consistency.
2. Plate the noodles, top with cooked chicken, garnish with parsley, and serve warm.
