Heat the oven to 400°F (204°C). Line a large baking sheet with foil.
Pat the chicken dry and place it on the baking sheet. Whisk the olive oil and lemon juice together, then rub the mixture over both sides of the thighs.
Mix the lemon pepper seasoning, salt, garlic powder, onion powder, Italian seasoning, and paprika. Sprinkle evenly over the chicken.
Bake for 35–45 minutes, until golden and an instant-read thermometer inserted into the thickest meat without touching bone reads at least 165°F (74°C). Serve hot.
