The 6-foot-7 Adel was the top prospect the Cardinals targeted in the '15 class for more than a year. Assistant coach Mike Balado jumped into the mix with Adel last summer.
Adel is ranked No. 18 in the Class of 2015 rankings by Scout.com and is a five-star prospect. He has shown tremendous upside with Florida Elite on the adidas circuit this spring and rose to No 18 from being unranked.
"It just felt like home. I love the style of play," Adel told Cardinal Authority. "I just loved everything about (Louisville)"
Adel also held scholarship offers from Connecticut, Florida, Georgia Tech, LSU, SMU and Virginia Tech.
"We felt really comfortable with the situation at Louisville," said Loren Jackson, who is Adel's guardian and coach. "I've known coach Pitino since I was 14 and it's a good fit for DA. It's just a perfect fit for him."
During the adidas event in Chicago last week, Adel was named to the All-Star team. He was one of the top prospects of any class at the camp.
"Adel is an exceptional athlete and has very good size for a wing at 6-7," Scout.com national analyst Evan Daniels said. "He's quick, can make shots off the catch to three and is improving as as mid-range jump shooter. He also plays very well in transition and in space.
"Adel is a good fit for Louisville's system and should be effective in their press. He has a lot of potential on the defensive end because of his lateral speed, length and overall athleticism. He takes that end of the floor seriously."
Jackson is also Adel's coach at Victory Rock. He was current U of L center Mangok Mathiang's guardian and was also Mathiang's coach.
"Mangok went there and wasn't a highly-ranked kid and started as a freshman for coach (Pitino)," Jackson said. "So we know it's a good place. Mangok loves it there.
"When (Adel) went on his visit he felt comfortable. He said to me, 'We do that drill, we do that drill.' We run the same things, we do the same drills, it was all familiar to him."
Adel is a native of Sudan who grew up in Australia, noting he had known Mathiang "all my life." Adel averaged 22 points and eight rebounds in his first season at Victory Rock.
"I like the style of play at Louisville and am just very excited," Adel said. "I'm happy and (Pitino) was really happy when I told him."
Jackson said when he spoke to Pitino on Monday his conversation was "genuine," noting that Pitino said the news "made him very happy."
"He said it's the happiest he's been in recruiting in 10 years," Jackson said.
