Many also admit the man of the house is now better at cooking than they are, while others are just too busy to find time to get to grips with a recipe book.
The report - which looked at the culinary skills of 2,000 people - also found a handful cannot boil and egg and wouldn't feel confident cooking a fry up.
It was discovered that the typical female can cook just seven different meals from
scratch - HALF as many as their mums regularly served up.
More than one in five struggle with a basic curry, one in six can't bake a cake and three in ten have 'no idea' how to make a meringue… you can almost hear the collective gasp of horror from the WI can't you?
One in ten of those polled have never cooked a roast, 13% wouldn't know where to start with a fish pie and one in ten can't make lasagne. A further 6%, even shy away when tasked with making fairy cakes.
Shockingly, one in ten can cook fewer than three meals without looking at a recipe book or asking for help. However, 30 years ago four in ten women could easily whip up twenty or more meals off the top of their head.
Roopa Gulati from the Good Food channel, which commissioned the study, said: "The research shows how busy lifestyles and a lack of culinary know-how are impacting on the dishes we feel confident to cook.
"This study shows that everyone is increasingly pushed for time, and women in particular are finding it harder than ever to balance work and home lives.
"It's happening so much that many are resorting to quick fixes in the kitchen, rather than cooking from scratch."
