Tenderize each chicken breast by pounding between plastic wrap or in a Ziploc bag for 10-15 seconds per piece.
Mix avocado oil and lemon juice, then coat the chicken breasts and season with salt, pepper, onion powder, and garlic powder.
Air fry the chicken at 380°F (193°C) for 11-14 minutes, flipping halfway, until internal temperature reaches 165°F (74°C). Rest, then dice into bite-sized pieces.
Cook pasta in boiling salted water until al dente (about 11 minutes), drain, rinse with cold water, and set aside.
Combine cooked pasta, diced chicken, olive oil, lemon zest and juice, herbs, shallot, and parmesan in a large bowl. Toss and adjust seasoning as needed.
Notes
Serve immediately or store in the refrigerator for up to 4 days. Drizzle with additional olive oil if pasta appears dry.
