Pretty hard to avoid the stereotypes on the internet I am afraid. Culinary history is a particular obsession for me, so I can say some things about it. Unfortunately most books on Dutch culinary heritage are on my shelf but written only in Dutch. Though
www.tasteatlas.com has a very broad selection of Dutch dishes available for viewing if you want a general idea.
I would describe traditional Dutch cooking as a hearty, rustic type of food comparable to British, Northern French ( Britanny, Normandy) , High German and Belgian cuisine.
It has a lot of seafood based food and small game like rabbits and hares, and a lot of dairy. Bread , butter and cheese are an ancient staple food, because before Columbus grains and dairy were our main staple foods.
Now, the potato is a staple food too but mainly in the shape of home fries or mash. Plain boiled potatoes are out of fashion.
Pancakes and poffertjes ( takoyaki in Japan) are also very popular foods as
TastyReuben mentioned. We even have pancake only restaurants .
As a side mention, the Japanese traded only with the Dutch in the 16th century. Through us they have their dishes named Takoyaki ( poffertjes) and Korokke ( kroketten) and birru ( beer) and chizu ( cheese) .
Edit; mispelled takoyaki
