The pan-European FTSEurofirst 300 finished around 0.8 percent higher at 1,569, with all major bourses and sectors posting solid gains, having touched a seven-and-a-half-year high earlier in the session of 1,572.

European investors listened intently to ECB President Mario Draghi's regular press conference. He said that the central bank's 1 trillion euro ($1.1 trillion) bond-buying program would start on March 9. He also upgraded the ECB's economic growth forecasts for 2015 and 2016 to 1.5 percent and 1.9 percent respectively.

Draghi's comments boosted German stocks, which closed around 1 percent higher, while the French CAC ended around 0.9 percent higher. London's FTSE 100, which is not part of the euro area, finished almost 0.6 percent higher.

Stocks briefly pared gains when Draghi started speaking, before resuming their earlier trend. The euro slumped to record lows against the dollar, breaching the $1.10 level in late trading following Draghi's remarks.

U.S. stocks traded mildly higher on Thursday, breaking a two-day decline with a boost from details on quantitative easing in the euro zone, ahead of Friday's jobs report.
