Pat chicken tenders dry with paper towels to ensure optimal Maillard reaction.
Season chicken evenly with salt and black pepper.
Lightly coat each tender in all-purpose flour, shaking off excess to leave a thin, even layer.
Heat olive oil in a large heavy-bottomed skillet over medium-high heat until shimmering.
Arrange chicken tenders in the skillet in a single layer, avoiding overcrowding; sear for 3 to 4 minutes per side until the internal temperature reaches 165°F (74°C).
Transfer the cooked chicken to a warm plate and set aside.
Reduce heat to medium; add butter to the skillet and whisk to deglaze the pan.
Add minced garlic to the melted butter and sauté for 60 seconds until aromatic and translucent.
Incorporate the lemon zest, lemon juice, and chopped parsley into the butter sauce, whisking to emulsify.
Return the chicken tenders to the skillet and toss briefly to coat thoroughly with the sauce before service.
