A dominant first-half performance ensured that United just had to control and dictate the second 45 minutes, something they did perfectly.
A third league goal of the season for Kathleen McGovern put the Lasses ahead, before former Magpies Deanna Cooper turned the ball into her own net at the near post to double the lead.
Burnley failed to truly test United, with Kayla Rendell not forced into any saves throughout the game, and after Martha Thomas’ ninth strike across all competitions, it was the end of the contest.
Tanya Oxtoby handed a first league start to Hanna Németh at St. James’ Park, with the Hungarian international forming a solid partnership with Gemma Evans to record a clean sheet.
United wanted to make a fast start at St. James’ Park and give their fans something to cheer about, and the East Stand were on their feet after 10 minutes, but it was more in anticipation.
A Nobbs cross from the left was deflected over everyone apart from McGovern, who found herself almost on the goal line but failed to make contact with the ball from a yard out.
However, the Lasses were not to be denied much longer as 60 seconds later McGovern did find the back of the net.
The ball was laid back to Joel outside the box, who delivered a perfect curled delivery, taking out the entire Burnley backline and setting up United’s number nine to find the far corner for her first goal at St. James’ Park.
Newcastle maintained their blistering start to the game as they doubled their lead just six minutes later via a helping touch from former Magpie Cooper.
Lumsden carved open some space near the byline and whipped in an in-swinging cross which looked to be collected by Levell, only for Cooper to intervene and prod into her own net seconds before.
Oxtoby’s side were flexing their muscles on the pitch against Burnley and looked destined to be 3-0 ahead.
A fizzed-in ball from Kaitlyn Torpey to Martha Thomas, whose first-time lay-off to Jordan Nobbs opened up space for her to curl an effort to the bottom corner, but was denied by a stunning Levell save.
The United faithful were on their feet again moments before half-time after a loose ball in the box fell to Bradley, but she could only find the side netting, much to the disbelief of Newcastle supporters who thought it had crept in.
Burnley came out for the second half looking to take the game to United, and the veteran striker Rachel Williams showed her quality by riding two challenges in midfield before threading through Emma Siddall.
The attacking full back galloped towards goal, leaving United’s defence behind, but couldn’t get over the ball as she fired over both Kayla Rendell and the crossbar.
Newcastle extended their lead after the hour mark, and WSL2 top scorer Thomas got in on the act. A mazy run from Lumsden saw her eventually pick out the number 17, who took a touch to compose herself six yards out before slotting home at the Gallowgate End.
