The UK was McDonald's best performing major market last year as consumers were drawn to its value meals in the recession, the firm said.
McDonald's hailed a "record breaking" performance in 2009 with like-for-like sales up 11% and 7.5% growth in the number of customer visits.
The fast food giant also announced plans to create another 5,000 new jobs in 2010 as its restaurants are now busier and open longer, while 10 to 15 new outlets are also planned.
McDonald's brushed off the recessionary gloom with its strongest results in four years as it grew its share of the market and said it had added £485 million to sales in the year.
Steve Easterbrook, chief executive of McDonald's UK, said "now more than ever" value was important to customers and the firm wanted to offer "good food that is affordable to everyone".
The firm has seen growth across its menus, with particular demand for its "saver menu" and a new "little tasters" value offer.
McDonald's UK outdid the global group, which saw like-for-like sales of 3.8%, Mr Easterbrook said the country was the top performer of the firm's best ten markets.
The 5,000 new jobs will mainly be in existing restaurants as they gear up for longer opening hours - taking advantage of breakfast and late night customers - and increasing customer numbers.
McDonald's added 6,000 jobs last year, 2,000 more than it had expected and taking its overall headcount to 80,000.
Group net income was up 6% at 4.55 billion US dollars (£2.83 billion).
