In their first season as part of the Big 12, the Knights jumped out to a 3–0 start, including a last-second victory at Boise State. However, quarterback John Rhys Plumlee suffered an ankle injury in the final minute of the Boise State game, which would sideline him for a month. Redshirt sophomore Timmy McClain took over at quarterback as the Knights entered the conference portion of their schedule. In their first intra-conference home game, the Knights jumped out to a 35–7 lead over Baylor, but blew a 28-point lead, and lost 36–35. The Knights suffered a five-game skid, slipping to 3–5. With Plumlee back to full strength in November, the Knights won three of their last four games to finish the regular season 6–6 overall (3–6 in the Big 12), and became bowl eligible for the eighth consecutive season. Of the four newcomers that joined the Big 12 for 2023 (BYU, Cincinnati, and Houston being the others), UCF finished with the best record, and was the only one bowl-eligible.
The 2023 UCF spring exhibition game was played on Friday April 14 at FBC Mortgage Stadium. The team was split into two squads for gameplay, the Knights and the 'Nauts.[5]
The 2023 season is UCF's first as a member of the Big 12 Conference.[22] The conference utilizes a nine-game conference schedule, with three out-of-conference games annually.[23] Furthermore, the conference requires at least one of the three out-of-conference games to be against a Power Five opponent.[24] UCF successfully petitioned for a first-year, one-time waiver to count their game at Boise State as their Power Five non-conference opponent, taking into account Boise State's recent successes and status as a top Group of Five team.[24]
Quarterback John Rhys Plumlee threw for 281 yards and rushed for 90 yards as the Knights routed Kent State 56–6 on Thursday night. The game marked UCF's first football game as a member of the Big 12. The Knights won their 8th consecutive season opener.
Colton Boomer kicked a 40-yard game-winning field goal as time expired to lift the Knights over the Boise State Broncos by the score of 18–16. Boomer went 4-for-4 on field goals, including a school record-tying 55 yarder in the second quarter. Late in the game, quarterback John Rhys Plumlee suffered a leg injury which will require him to miss multiple weeks.[28]

The game was tied 24–24 midway through the third quarter, but Kansas State put the game away with 20 unanswered points. Ten penalties for 80 yards on UCF, two turnovers in Wildcats territory, plus a lopsided time of possession were factors in the loss.
UCF hosted Baylor for their first intra-conference home game in the Big 12. The game was a rematch of the 2014 Fiesta Bowl. The Knights blew a 35–7 lead. Baylor scored a go-ahead field goal with 1:21 remaining and won 36–35. On the first play from scrimmage, Johnny Richardson broke free for a 79-yard touchdown run, and after two more quick scores, UCF jumped out to an early 21–0 lead. The Knights eventually built a 35–7 lead, which they held late in the third quarter. Baylor scored 29 unanswered points, including two touchdown passes from Blake Shapen, and a 72-yard fumble return for a touchdown. UCF got the ball back one last time with 1:21 remaining. Colton Boomer's 59-yard field goal attempt fell no good as time expired, and Baylor escaped with the victory.

Ollie Gordon then fumbled in Knights territory, which led to a 7-yard touchdown pass from John Rhys Plumlee to Kobe Hudson. Braeden Marshall picked off Alan Bowman's deflected pass, which led to a Knights field goal early in the second quarter. A huge downpour then pelted the stadium, but it did not slow down the Knights offense. Plumlee found Kobe Hudson for a 75-yard touchdown, and the Knights led 24–0 at halftime.
Oklahoma State got the ball to start the third quarter. The Cowboys drove to the Knights 7 yard line, but had to settle for a field goal.
