In March 2021, Migliozzi was a joint runner-up in the Commercial Bank Qatar Masters, one stroke behind Antoine Rozner who won the tournament with a 60-foot putt at the final green.

In May, he lost in a playoff at the Betfred British Masters. He was defeated by Richard Bland at the first extra hole.[6] Two weeks later, he finished second at the Made in HimmerLand, five strokes behind Bernd Wiesberger, after a final round 63 in which he birdied four of the last five holes.

Qualifying for his first major championship, the 2021 U.S. Open, he finished tied for 4th, thus earning him exemptions for the 2022 tournament as well as the 2022 Masters Tournament.

In September 2022, Migliozzi won the Cazoo Open de France. He shot a final-round 62 to win by one shot over Rasmus Højgaard, after making a birdie on the final hole at Le Golf National. It was the first birdie of the day on the hole; ranked as the most difficult hole on the European Tour season.
