Narrative: Operating flight from ZZZ-ZZZ1; pushed about 5 mins early. I was the PF (Pilot Flying); for the leg. During the push we started E1 first normal start. Then; we taxied out to Runway XXL at DD; it was a long taxi from the North Port. Once in line on N for departure started E2 with no problems; set hydraulics and shutdown the APU. Received a Line Up and Wait clearance with an advisory about a helicopter operating 2 south of the field; we taxied onto the runway and completed the Before Start Checklist. Once on the runway; controls we transferred to me. We received our take off clearance to fly runway heading and stay with the tower. Takeoff roll everything was normal; and the departure was normal. Tower gave us two vectors; 180 and 220 respectively; presumably around the helicopter traffic. Then switched us to departure. CA (Captain) Pilot Monitoring (PM) checked in with departure; who didn't give us higher initially; So we were leveling at 5000 ft. Once level; departure gave us a climb to 15;000 ft.; which we read back and started climbing. About 5500 ft.; during the climb there was a loud bang from the left side of the aircraft; immediately the E1 started to roll back; with a Amber E1 Fail message on the EICAS. CA (PM) identified and cancelled; and began running the QRH; at the same time departure had cleared us direct to ZZZZZ. The CA [Requested Priority Handling] and advised we would need vectors to return to ZZZ. Departure assigned a 280 heading and maintain 6000 ft.; which I complied with and set into the FGP and turned off the autothrottles. The CA continued to run the QRH; we attempted the auto relight procedure which did not happen. There was no oil pressure; but full quantity. So the engine was secured using the QRH. We then established with approach that we would return to ZZZ; they told us to expect Runway XXC. Approach gave a few different westerly vectors to give us time to run the QRH; and get set up for the approach. The CA attempted to talk to the FAs (Flight Attendant) using the EMER call button; after they picked up he was unable to hear himself or them or me with his headset (no idea why). I could hear him and the FAs just fine; so I talked with the FAs told them we had an engine failure; we would be returning to ZZZ in about 10-15 minutes; there would be no need for brace. He was finally able to get back on the headset; and hear normally. He continued to notify and sent an ACARS message to Dispatch to advise our return and made a PA to the passengers. The CA continued the QRH; and setup the Runway XXC approach. We considered the Runway XXC approach briefed as we had just done the approach on leg 1 of that day into ZZZ. We advised approach we were ready for the approach and vectors were given onto the approach; we were over KARR in the turn. The CA followed up with the FAs on the normal call button; and was able to talk with them and make sure everything/everyone was safe and ready. They advised the cabin was secured and ready. We continued on the approach; and they wanted us maintain 210 till ZZZZZ1; and then 170 till ZZZZZ2. I slowed a little before ZZZZ2; during configuration so we were configured and stable a little before the FAF. Which meant we were slower than 170 before ZZZZZ2 (probably 155 or so). We followed the ILS glideslope and localizer in and landed on Runway XXC. Tower advised us to expected a right turn off after landing and the [airport rescue and fire fighting] would inspect. We turned right on F and left on RR and stopped had [airport rescue and fire fighting] inspect the left engine for signs of damage. They reported no visible damage; fire; or leaking fluids. We then advised ground that we were ready to taxi to the gate; and taxied to the gate and parked without incident. Passengers deplaned; and I completed the post flight inspection; did not note any other damage to the aircraft or damage on the external of the engine. Company Maintenance personnel met the airplane as well.
