In spite of chaos surrounding Brexit, the U.K.'s FTSE 100 popped 0.92 percent, while the French CAC 40 rose 0.42 percent and Germany's DAX finished up 0.38 percent. Peripheral markets across the board finished in the black.
Basic resources outperformed peers, rising some 2 percent as trade war news took a breather. The upbeat sentiment was supported by the latest Sentix survey, which measures investor confidence in the eurozone. The index rose to 12.3 in July, from 9.3 in June.
Looking at individual stocks, shares of Air France-KLM soared to the top of the Stoxx 600 after posting higher passenger numbers for June, despite several strikes. The airline climbed 6.34 percent, only to be outpaced by Inmarsat. The London-listed firm closed up over 7 percent.
Sticking with the top performers, Tgs-Nopec jumped almost 6 percent after reporting higher revenues for the second quarter compared to a year ago.
On the other hand, French food producer Danone foundered near the bottom of the index, slipping 2 percent. News has emerged that the firm is looking into reports that its Aptamil baby milk formula is making some infants sick.
French carmaker Renault came off its lows, but closed lower on concerns about its partner company Nissan. The latter has admitted that it falsified exhaust emission and fuel economy data in Japanese passenger vehicles.
The worst performing sector was utilities, closing down 0.96 percent, with all three of the Stoxx 600's biggest losers coming from the sector: Rubis, Severn Trent and Pennon Group.
