Roast pumpkin is a staple here. We use it with roasts like potatoes in salads in pasta, as soup. Pumpkin pie is a fairly North American thing you rarely see it out here...
More about pumpkin than anyone probably wants to know, but I can't resist.
In the North America, most pumpkins are grown for processing (and end up as pies) and for ornamental use (Halloween). However, since the 1970's pumpkins for use as vegetables have become more and more common across the US. This is being spurred on by increased interest in vegan/vegetarianism, American food and immigration from "pumpkin-eating" countries in Latin America, Africa, India, China and others.
Pumpkin is an essential part of Oaxacan cuisine (southern Mexico) and found across Mexico, Central America and large parts of the US used as a vegetable. It has been grown in Ozxaca for over 7,000 years.
Pumpkin used as a vegetable was a staple of Pre-Columbian cuisine across most of what is now the US and adopted by early settlers -- most commonly roasted and made into soups. It was replaced in the 18th and 19th century by butternut and other winter squashes which have higher yield per acre, keep longer, are not as easily damaged by freezing when stored and are more versatile. Pumpkin and pumpkin seeds started to become more common again (beyond pies) in the 1970's.
Today, pumpkin and pumpkin seeds are a essential part of contemporary American cuisine -- not just in NY and LA, I have recently seen pumpkin as a geatured part of dishes in restaurants in Louisville, KY, St. Louis and Cleveland, OH.
The top pumpkin growing countries: China (#1 by far), India, Russia, US, Egypt.
Pumpkin is also part of North African, Northern and Central Italian and Italian-American cuisine -- pumpkin risotto for example.
Oddly, pumpkin rarely appears on even Oaxzcan-style restaurant menus in the US.
I believe that pumpkin pie is only common in North America -- it originated in Massachusetts colony in the early 1600's and is one of the oldest colonial recipes. But almost all the pumpkin pies are eaten from November through January. It is really seasonal.
