The high-end supermarket believes customers are going out less due to stagnating wages and instead choose to treat themselves at home.
It pointed to double-digit growth in sales of artisan bread, gourmet cheese and dry-aged beef as further proof of this.
Sam Dickson, head of Brand and product development at Waitrose, said: “There’s no doubt that our more premium ranges are proving popular with customers as they add an indulgent treat to their shopping.
“A fine bottle of wine or hand-made speciality loaf is now a regular appearance at dinner, proving that quality produce still very much matters.”
Waitrose is also capitalising on the growth in demand for wine, bread and cheese by selling deli boards and wines by the glass to shoppers.
