Air Carrier flight crew reported a strong electrical odor during initial climb. After completing memory items priority handling to departure airport was provided where a safe landing was executed.

Narrative

After takeoff; climbing through about 1;000 ft.; the CA (Captain) smelled a strong electrical odor and asked the FO (First Officer) if he smelled it. The FO confirmed that he did. CA transferred control to the FO; contacted the FAs (Flight Attendants); and asked if they smelled it. FA2 said there was a strong smell; but the FA1 did not smell anything. CA informed them that they would be heading back. CA and FO completed the memory items and the CA began performing the QRH procedure. [We advised ATC]; and we began receiving vectors for an immediate return to ZZZ. CA sent an ACARS to Dispatch and radioed ZZZ Operations. After selecting the bleed are valves off; FA2 confirmed the smell was dissipating so we held the QRH there. We set up for a visual to [Runway] XXL backed up by the ILS; transferred control back to the CA; and landed. Total flight time was 11 minutes. On the ground; we stopped on the runway to allow CFR to perform thermal imaging checks of the aircraft which were negative. We taxied to the gate. CFR boarded the aircraft and performed more thermal checks on the interior of the aircraft which were also negative. Upon arriving at the aircraft; Maintenance Control also stated that they could smell the electrical burning odor. Additionally; after the flight; FA2 stated that a deadheading pilot and an off-duty FA had informed her that they too had smelled the odor.
