Eating won't be until tonight, in the Netherlands it's most common to have a big dinner with family on christmas day, often followed by a second one with the other side of the family, or with friends a day later. Those days are officially called 1st and 2nd Christmas day around here.
Christmas eve isn't a big thing, unless you're religious, which I'm not.
My uncle usually makes a pretty traditional Christmas dinner: First two starters, of which one is always a ragout in a small puff pastry thing, typical Christmas fare.
For mains at least two kinds of meat, sometimes three. Often something unusual like deer, boar, or hare. Multiple vegetable dishes and salads, and potatoes made in different ways. Always sweet cooked pears.
And some spectecular dessert made by my cousin.
Another traditional thing many people do at Christmas is 'gourmetten'. No idea what this is called in English, everyone has their own mini frying pan to cook what they want at the table. Children tend to love it, and it's not a lot of work for preparation, so ideal for parents.
