Preheat the oven to 425°F (220°C) and lightly spray a baking sheet with non-stick spray; alternatively preheat an air fryer to 400°F (200°C).
Season the chicken tenderloins with the 3/4 tsp kosher salt and black pepper to taste.
In a shallow bowl combine the sesame oil and soy sauce.
In a second shallow bowl mix the toasted sesame seeds, 1/2 tsp kosher salt, and panko.
Dip each seasoned chicken tender into the sesame oil and soy sauce mixture, then press into the sesame seed–panko mixture to coat all sides evenly.
Place the coated tenders on the prepared baking sheet and lightly spray the tops with olive oil spray.
Bake in the preheated oven for 8–10 minutes, then flip the tenders and bake another 4–5 minutes until cooked through and edges are crisp. Total oven cook time about 12–15 minutes.
For air fryer: cook at 400°F (200°C) for 10–12 minutes, flipping halfway, until golden and cooked through.
Serve immediately, optionally over rice with extra soy sauce if desired.
