Ahli Dubai midfielder Hosni Abd-Rabou was also on the scoresheet to help the Pharaohs brush aside minnows Benin.
Striker Razak Omotoyossi scored Benin's consolation five minutes from time.
Egypt laid siege to Benin's area from the very beginning and penetrated their shaky defense on several occasions.
Blackburn Rovers-target Ahmed Al-Muhammadi whipped in some pinpoint cross from the right flank in the early stages of the game.
But Emad Meteb, who played as a lone striker due to the absence of injured duo Mido and Amr Zaki, failed to get on the end of any of them.
Petrojet's in-form midfielder Walid Soliman, who was given a rare start, made a fine impact as his brilliant footwork and deft passes helped his teammates launch constant raids on the visitors' goal.
The hosts were awarded a penalty after 21 minutes when Meteb was sandwiched between two Benin defenders.
Spot-kick specialist Abd-Rabou stepped up and fired into the bottom corner as the keeper's attempt to block his effort went in vain.
Meteb doubled Egypt's advantage five minutes later in an unfortunate manner.
Soliman tricked a challenger inside the area before drilling the ball across the six-yard box.
A headed clearance by a Benin defender struck the woodwork and fell kindly for the unmarked Meteb to volley into an empty net.
The Ittihad Jeddah on-loan striker added the third in the 41st minute when his low shot, though weak, struck the keeper's legs and went into the back of the net.
Abou-Treika put the result beyond doubt two minutes before the break when he cut inside his marker before firing a powerful right-footed shot into the far top corner.
Fringe Players
Egypt coach Hassan Shehata introduced Wael Riad, Ahmed Eid and keeper Abdul-Wahed Al-Sayed in the second period.
He was trying to make the most out of the friendly game by giving chance to some fringe players.
Abou-Treika wasted a glorious opportunity to add the fifth goal three minutes after the restart when he went one-on-one with the keeper but his shot with the outside of his foot missed the target.
Meteb could have also completed his hat-trick in the 64th minute but his free header went just wide of the post.
He made amends in the 74th minute when he tapped into an empty net after being fed by Abou-Treika's precise low shot.
Benin notched a consolation five minutes from time, thanks to Al-Sayed blunder.
The Zamalek guardian failed to handle a tame Omotoyossi shot that struck the post before rebounding into his path.
The Al-Nasr striker made no mistake at the second attempt.
