Are Sunday roast dinners a UK meal or do people from America and other countries enjoy a roast?

I grew up in the Midwestern US, and everything you mentioned would have been either common or at least familiar at any table in town. Lamb was not terribly popular, but not unheard of, either. Yorkshire puddings would have probably only been served routinely at the house of an English/American family I knew from my church. But there would always be some kind of similar side dish or accompaniment like mashed potatoes and gravy, dinner rolls, cornbread, or a sort of cross between pudding and cornbread known as "spoon bread." Roast turkey is a ubiquitous dish for Thanksgiving, at the end of November, and is usually served with stuffing, a dish similar or most likely derived from British puddings. Incidentally, what Americans generally refer to as pudding is a custard-like dessert commonly flavored with chocolate or vanilla (tapioca is my favorite).

There is quite a history in this part of the world, since the time of European colonization, of adapting traditionally European dishes to include ingredients more commonly found here such as corn, squash, pumpkin, beans, sweet potatoes, tomatoes, and other indigenous favorites. Many of these foods were unknown to Europe prior to the 16th Century and subsequently became parts of European cuisine as well. There are also variations on older recipes. A specific example of this is the American biscuit, which is a quick bread and clearly a variation of a scone or bannock. I am certain that you would enjoy cornbread, and that it's texture if not it's taste might be familiar or even comforting to you.

We always had a nice pot roast on Sundays growing up in Illinois with a ton of potatoes in the pot as well.
I married an Italian so we now have super big Sunday dinners but rarely roasts

Sunday roast dinners were served on Fridays in my home and usually consisted of Soup, Roast Chicken, Pot Roast or Roast Beef, roasted potatoes and vegetables. Dessert was sponge or marble cake. My Italian neighbors had their Sunday family dinners on Sunday but it usually consisted of antipasti, pasta and then a roast or lasagna etc. and salad. Our Irish neighbors usually had Sunday dinner also which consisted of some type of roast meat or stew. Most of my neighbors were 2nd or 3rd generation Americans and families tried to have at least one large meal each which included extending family. As children moved away, this became more difficult and family meals became more of a holiday event.

The way you do it is specific to the UK. Ask any American what Yorkshire pudding is, and they won't have a damn clue what you're talking about. Most likely they'll misunderstand and think you're talking about a dessert rather than a type of quickbread.

But the overall meal of a roast, yeah. We have that. The most common is pot roast, which is technically closer to braising than roasting... but same idea. Beef with gravy/jus, mashed potatoes, carrots and/or peas, and usually a dessert of some kind. But here in the US it's increasingly uncommon for people to cook, especially larger, more ornate meals. The traditional family dinner is, unfortunately, a collateral casualty of having both parents in a household working full-time. Also, lamb is prohibitively expensive in the US and is considered very much a luxury item.

Depends on what kind of roast I suppose. But, yes, Sunday dinners are usually festive occasions that bring family and/or friends together to finish the weekend and kick off the beginning of the week. While some folks may not prefer the standard roast, you'll find lots of people that like the tradition of creating a meal that brings people together. One of my favorites is roasted pork with sweet potatos or ginger glazed carrots, mashed potatos and spinach salad.

I had a lot of roast chicken dinners on Sunday growing up, occasionally pot roast, once in a blue moon, lamb. Not every week.

I often have dinner parties Sunday now. Not usually roasts. I like variety.

It wasn't just an idea of the English, a roast dinner comes in different ways, take the Polynesians, they have what are knowns as hungi's, where meats and vegetables are cooked in the ground.

The Australian Aborigine would throw a freshly hunted Kangaroo, or large Goanna on a fire. Same with the American and Canadian Indians. Europeans were good hunters, and would prepare the kill in different ways, either in a wood fired oven, spit or grate. So roast dinners were not just an English invasion.

there is nothing as delicious as a nice roast beef, carrots, onions, and potatoes roasted with the meat, rich brown gravy for over the veggies. yup. You bet people in America eat that.
I also love a good pork roast, done the same way but with a few differences. Instead of red wine like on the beef, I like a nice dark beer, lots of garlic too.

Being as my family was of UK heritage we did have the occasional one, mostly roast beef or pork, chicken at times, my Mother was Irish and for some reason hated lamb and mutton, we always had mashed or roasted potatoes, veg and maybe 2, not much else, my parent had meager jobs and with 5 mouth to feed even a 5 lb roast had to make it threw 2-3 meals and sandwiches, my mother sliced it paper thin, there was more meat in the my gravy.
