Jodar's 6-3 6-2 win over Marco Trungelliti on Sunday (Monday AEST) put him into an elite group of Spaniards who captured ATP titles as teenagers in the professional era, including Rafa Nadal, Carlos Alcaraz, Carlos Moya, Juan Carlos Ferrero and Tommy Robredo.
Ranked outside the top 900 a year ago, Jodar has climbed to a career-high world No.57.
"It was the first tournament on clay for me so it was going to be difficult at the beginning, but I always have the mentality that I have to give my best tennis and what I have in that match," Jodar told the ATP website.
"That's what I did in all the matches, so it means a lot to win my first ATP title in Marrakech."
Jodar said he was trying to follow in the footsteps of his idol, 22-time grand slam champion Nadal, but he did not set himself targets for the year.
"I never set a goal in the season, just to try to give my best and improve my tennis level," he said.
"But overall I think I did a great week on clay here in Morocco, so I'm very happy how the week went for me and I will try to make sure this is just the beginning. It has to give me motivation for the next challenges."
Argentina's Trungelliti was left impressed by Jodar after a 69-minute mauling.
"Today, I guess I got kicked by this young man," said the 36-year-old, the oldest first-time tour-level finalist in the professional era.
"It was sad for me because I was expecting a great final, but at least you saw a great final from one side."
