Pat the chicken breast tenders dry with paper towels.
In a small bowl, mix kosher salt, black pepper, garlic powder, and smoked paprika.
Sprinkle the seasoning mixture evenly over both sides of the chicken tenders.
Heat olive oil in a large skillet over medium-high heat until shimmering.
Add the chicken tenders to the skillet in a single layer without overcrowding. Cook for 4-5 minutes without moving them until the underside is golden brown.
Flip the chicken tenders and add the butter and minced garlic to the skillet.
Cook for another 4-5 minutes, spooning the melted butter and garlic over the chicken as it cooks, until the chicken reaches an internal temperature of 165°F (74°C).
Remove the chicken tenders from the skillet and let them rest for 3 minutes.
Sprinkle chopped fresh parsley over the chicken before serving.
