"We'll probably add another 50 [shops] next [fiscal] year," chief executive Jim McCarthy told the Reuters news agency.
He added that the chain would offer permanent jobs to 360 temporary workers taken on over Christmas.
Meanwhile, the Co-operative, which bought Somerfield last year, said its customers had been "determined to make the most of Christmas", with sales of champagne up 83%.
The UK's fifth biggest food retailer said that the price cuts and promotional package it had launched in the run-up to Christmas had been "well-received".
But it warned that economic pressures would continue until the end of 2010 or the first half of 2011.
'Tough outlook'
House of Fraser said its sales growth reflected its continuing efforts to improve the business, including store refurbishments and developing its own-brand products.
Sales of brands owned by House of Fraser, including Linea, Kenneth Cole and Episode, rose 33%.
The firm said some of its branches, such as its flagship Oxford Street store, had enjoyed record sales, but added "the general outlook for retailing will be tough until the overall national economic position improves".
The first couple of weeks of 2010 may prove particularly difficult for retailers as the heavy snow and ice keeps shoppers at home.
Figures from research firm Synovate show that overall shopper numbers in non-food stores in the UK on Sunday 10 January were down 14% from the equivalent Sunday last year.
Since the most recent snowfalls began, retail traffic is running about 21% lower than last year, Synovate said.
