The continent-wide STOXX 600 index logged its best session since last November, bouncing back to levels before worries emerged about the new virus variant.

"Last week's sellers have been rudely pushed out of the way in a mad scramble to get back into equities now that Omicron fears are receding almost as fast as they appeared. Billions have been 'wiped on' to share prices since Friday's lows, December living up to its reputation as one of the strongest months for equities," said Chris Beauchamp, chief market analyst at IG.

Technology stocks surged 5.6% after hitting seven-week lows on Monday, while miners jumped as copper and iron ore prices were lifted by biggest consumer China easing its monetary policy. [IORNORE/] [MET/L]

"There's relief that although global fiscal policy is set to tighten over the next six months, it's not going to be within the next month," said AJ Bell financial analyst Danni Hewson.

The STOXX 600 is just about 2% below its record high from mid-November, while the Euro STOXX 50 volatility index, Europe's fear gauge, fell to 14.87. At the peak of the selloff in markets, it hit 33.1.

Luxury stocks were among the biggest boosts, lifting France's CAC 40 2.9%, while Porsche and Volkswagen led auto stocks higher.

The carmakers jumped over 8% each after a report that the Porsche and Piech families, who control Volkswagen's largest shareholder, are considering selling part of their VW stake and using the proceeds to buy a substantial number of shares in Porsche.

Carmaker Stellantis advanced 3.6% on plans to generate around 4 billion euros ($4.52 billion) by 2026 and about 20 billion euros by 2030 from software offerings.

Among individual stocks, British American Tobacco gained 1.0% after backing its full-year forecast, buoyed by more people switching to the tobacco giant's vaping and oral nicotine products.

Defensive sectors such as healthcare and food & beverages were among decliners on STOXX 600.
