Narrative:

After climbing through 10;000 feet when departing ZZZ and navigating to join the RNAV SID; the #1 F/a (flight attendant) reported a strong odor of burning plastic near the mid galley area. Ovens were empty and the source of the odor could not be identified. Both pilots were beginning to smell an odor of smoke in the cockpit; as well. Oxygen masks were donned by both pilots; and quick actions smoke and fumes procedures performed. Flight attendants called again and advised pilots of difficulty breathing. [Advised ATC] and we returned to ZZZ; which was about 50nm east of our position. Threat and error management methods were discussed and employed and task-loading concerns addressed. The first officer became the pilot flying and landed the aircraft in zzzan off duty pilot for another airline appears to be the first person to detect odors. He stated he first smelled the odor when engines reached flex power during the takeoff roll. Therefore; odors may be associated with high engine power settings.identify and repair faulty engines or seals. If this occurred during a trans-atlantic flight; we would not have enough crew oxygen and pbes (protective breathing equipment) to land safely considering we could be two or more hours from a diversion airport. Should more pbes be added to our aircraft until fumes incidents are corrected?
