Fill a large pot with water, add salt, and bring to a boil. Cook 8 ounces of pasta according to package instructions (about 10-12 minutes). Before draining, reserve 1 1/4 cups of pasta water.
While the pasta cooks, season the chicken strips with salt and pepper. Heat 2 tablespoons of olive oil in a large skillet over medium heat. Cook the chicken for 5 minutes on each side, or until the internal temperature reaches 165°F. Remove from skillet and set aside.
In the same skillet, melt 2 tablespoons of butter and add the minced garlic. Cook until fragrant (about 1 minute).
Add 4 tablespoons of fresh lemon juice (juice of 2 lemons) and, optionally, a splash of white wine. Scrape the bottom of the skillet to deglaze the pan.
Add the drained pasta to the skillet with the sauce. Toss well to coat the pasta.
Add reserved pasta water gradually to adjust the sauce’s consistency.
Return the cooked chicken to the skillet. Toss everything together to combine.
Sprinkle grated Parmesan cheese and lemon zest on top before serving.
