The discount supermarket reported record total sales for the four weeks to 27 December with revenue up 18%.
Takeaway firm Just Eat and online fashion retailer Asos have also reported stellar sales for the period.
All three benefited as restaurants and non-essential shops faced strict curbs or were forced to close.
Demand was so strong in the run up to Christmas, Lidl said it had shifted 7,000 glasses of mulled wine and almost 17,000 deluxe mince pies ever hour during December.
It also sold more than 2.7 million servings of panettone, the festive Italian cake.
Lidl continued to press ahead with its store expansion programme in the period, opening four new stores in December at a time when many businesses are closing down.
Boss Christian Härtnagel said: “Despite this Christmas being a difficult time for many across the country, we are pleased to have been able to help our customers enjoy themselves.
“As we look ahead to this year, we remain committed to our expansion and investment plans,” he added.
