This recipe is super flexible for substitutions. For veggies, easily toss in chopped asparagus, peas, or blistered cherry tomatoes, in addition to spinach, arugula, roasted broccoli, or sautéed mushrooms. For protein, use shrimp, pork tenderloin, or drained chickpeas for a vegetarian option. For cheese, Pecorino Romano or grated mozzarella can be used in a pinch. Fresh basil or thyme can be used in place of or in addition to parsley. Short pasta like penne, rigatoni, or orecchiette work well too. Don't overcook the chicken; use a meat thermometer to ensure it hits 165°F (74°C) for juicy results. Pasta water is key for emulsifying and clinging the sauce. Fresh lemon juice and zest make a noticeable difference in flavor. For convenience, you can prep and season chicken, chop onion, and mince garlic up to 24 hours ahead. Adjust sauce consistency with reserved pasta water as needed. If you like a little kick, add a pinch of red pepper flakes with the garlic. Store leftovers in an airtight container in the refrigerator for up to 3-4 days. To reheat, gently warm in a skillet over medium-low heat, adding a splash of chicken broth or cream to loosen the sauce. Freezing is not recommended for dairy-based sauces.
