The Magpies travel to Ashton Gate to face the Robins, who finished in 12th place of the Championship last season, as Eddie Howe's side continue their pre-season preparations for the new campaign following Saturday's 1-1 draw away at Gateshead.
Jaouen, who arrived at United from Ligue 2 side Stade de Reims last month, begins in-between the sticks in place of Nick Pope, who drops to the bench.
Sven Botman, who missed the Magpies' encounter at Gateshead, starts in central defence alongside Fabian Schär, who returned to footballing action last weekend for the first time since January.
Jacob Murphy, who captains the visitors this evening, is likely to feature at right-back while Lewis Hall will occupy the opposing defensive flank.
Sean Steur, who played the full 90 minutes against Gateshead, retains his place in the middle of the park along with Joe Willock and Jacob Ramsey.
Anthony Elanga, who represented Sweden at this summer's FIFA World Cup finals, is named in the starting 11 as well as Harvey Barnes, who signed a new long-term contract with the club earlier this week.
Sean Neave, who made his Premier League debut for United on the final day of the 2026/27 season against Fulham, will lead the line for his boyhood club.
It is a youthful bench, with nine of the 12 substitutes for tonight's friendly aged 20 or younger as they aim to play a part against Michael Skubala's men.
They include Leo Shahar, who started in last weekend's outing at the Gateshead International Stadium, as well as Park Seung-soo, Trevan Sanusi, Dylan Charlton, Anthony Munda, Matheos Ferreira and Mason Miley.
Rory Finneran targets a first public appearance for the Magpies at senior level after the 18-year-old midfielder played the second-half of a 3-0 friendly win against Darlington at The KNOX, while Alex Murphy, Miodrag Pivaš and teenage goalkeeper Aidan Harris are also on the bench.
The Magpies' last trip to Ashton Gate came in August 2016 as Dwight Gayle's first-half strike proved the difference in a 1-0 win during the 2016/17 Championship title-winning campaign.
