Pound each thigh to flatten and tenderize. Season both sides with salt and pepper to taste. Let rest for 3 minutes.
Beat 2 eggs in a bowl. Have flour and breadcrumbs ready. Coat each thigh on both sides by dipping first in flour, then in beaten egg, then in breadcrumbs.
Heat vegetable oil in a large frying pan over medium-high heat until shimmering, about 1 minute.
Fry the breaded thighs on both sides for 2 to 2.5 minutes per side until golden brown and the internal temperature reaches 74°C (165°F).
Transfer to paper towels to drain excess oil. Serve immediately.
