Concerned about how much my brother and his partner eat and worried I won't have enough

Definitely plate up the turkey, pigs, Yorkshires and roast potatoes. Have loads of veg that people can help themselves to buffet style. I’d keep back anything that you want to keep for leftovers (the best thing about Christmas dinner imo).
if you’re worried about oven space, Yorkshire puddings can be made earlier in the day, or even the day before, and heated through just before you eat. Even roast potatoes can be part cooked the day before and finish cooking on the day; this might enable you to cook greater quantities of cheap and filling carbs!

Gosh I would not only find that greedy but also just gross. That is gorging. Yuck.

So greedy CFs then. Keep all the expensive stuff back and don't let them wander off to get more meat. Serve it to them. If they eat potatoes do more specially for this couple. Also cheap Yorkshire puddings or extra if ready made ones. Extra gravy as well. Chances are their eyes are bigger than their stomachs and they'll fill up on these. Desserts like trifle, cheese etc serve it up for everyone and keep an eye on it. Also both people might sneak back later to fill up on leftovers (or steal them which isn't unusual on MN)
Medical condition? Both of them? Probably a case of Greedyitis

I think you may have just taught someone a very valuable lesson about judgement OP.

I second the pp that mentioned frozen Yorkshire puds - can whack packs in the oven when everything else is cooked and have them out on the table in 5 minutes.

Plate the some bits. Meats, pigs in blankets and stuffing maybe. Then buffet style the veg, potatoes and sides. They’re all reasonably cheap and he could go to town on those. That was everyone’s fed, everyone’s happy!

You need to plate up everybody’s food and get some cheap supermarket value roasties and Yorkshire’s on the side for him that you stick in the oven / air fryer last min so he feels like he can add more but it’s not the main food you’re cooking and he’s eating all off.

To be honest, I am wondering if he has an actual medical condition, either mental or physical that makes him behave in this way. It's all very well people considering him just to be rude and/or greedy but I have to question whether this is the case or whether this is some sort of illness. My biggest concern here would be the fact that he doesnt seem to show any signs of etiquette when it comes to meals with others. I would have expected him to be able to show some restraint when sharing with others in a buffet style situation but this doesnt seem to be the case and I would have to question why. Same with his partner I guess.

Plate everyone's up,or maybe before the day have a whatsapp group asking before hand what everyone likes, plate up for everyone, but have buffet style for what remains, so people can help themselves AFTER they have eaten whats been served, your bother sounds like an inconsiderate pig, and seems to treat free meals, like an all you can eat buffet as if he's paid for it and wants to eat as much as possible to get his moneys worth.
Pile his and partners plates with extra veg, pre cook a load of sausage rolls and nuggets the day before as well, have them out for people to pick at before dinner, maybe mention to others normal people who know how to behave at group dinners, to not eat it and save themselves for the nice dinner, dessert should be portioned too, but buy a ton of cheap mince pies and crisps, cakes etc once again for the greedy ones to gorge on. I do wonder is your brother and partner obese, does he have financial difficulty to always hungry. Give him loads of drinks as well, they give free fizzy drinks in all you can eat buffets as it fills everyone up and they eat less.
Sounds like your brother has an eating disorder or some kind, and maybe have a chat with him before hand over the phone as well, can't be picked on if it's a single one to one phone call

Hide the cheeseboard though until you are ready for everyone to enjoy it.😟

I don't think calling any human regardless of their appetite a "pig" is helpful in any way

Plate up the key stuff (ie meat, Yorkshires). Then just make sure there is a shit load of the cheaper stuff, especially loads of veg. Surround them both with big bags of crisps and nuts and satsumas or whatever. But don't let them help themselves to key stuff like the meat. Or the pudding, depending on what it is.

Sounds like they both have a complete lack of social awareness.

This doesnt sound like plain greedy selfishness.

Sounds like some form of ND or perhaps an eating disorder. If he is awkward and doesnt really get social cues then that really does point towards ND. That there is no off switch makes me think that there is a massive issue here, was he like this as a child? Or was food on the scarce side?

I think that plating up is the only way to do this because it will make sure everyone gets their fair share, and he wont draw attention to himself. I would make sure he and his partner have lots and lots of veg, more than the others.

I would honestly to god tell him. I have made enough food for everyone, you are not going to put it all on your plate. It is selfish to do this so dont do it or you wont be invited ever again.

It seems like nobody has done this before, he needs it pointing out it is fucking rude!!

Tell them to arrive an hour after others have eaten. Serve them their food in those baco foil roasting tins. Or just go farm foods and stock up on cheap food for them

This with bells on!
If you arent close with him and feel uncomfortable saying anything, then get your mother to do the dirty work. He is her son afterall.
I would be repulsed though to even look at him plating and eating to be honest.
Have you ever been invited to his house? How much food does he serve his guests there and how much does he eat?
I bet only a fraction of what he hovers up at other people's expense!

*sorry edited for typos

You'll realy have to serve people at the table. Carve at the table - it's traditional & easy enough - you just ask each guest what they want.

Try to manage it so that you serve your DB + partner towards the end. And have lots of green vegetables (cheap & filling) like broccoli and sprouts.

Is your DB very obese?

My family always joke that my husband and I eat lots and it's true we eat more at Christmas/special occasions but I'm talking 2 Yorkshires. We are both thin and eat healthily but are hungry people. Your brother isn't hungry though, he's greedy and selfish. I don't think you should serve up because I find that a bit childish but you should make them go last!

Plate up portions. If he goes to serve himself, tell him and partner they can't load up and leave others without. Call him out if he tries to take more than his share. If he's rude enough to eat so much others go without, be direct in addressing that.

There is a limit to how much you can serve from a residential kitchen and if he thinks he will need more, he's going to have to bring some food himself. You might suggest that.

Next year, do a tasting menu only. 😂

I think you need to plate up then put extra veg/yorkshires on the table. Seat them next to a mountain of mashed potato which is one of the most satiating foods and let them loose.

I'd politely tell him not to be greedy or give him a smaller plate.

sounds horrendous and stressful OP...

• I would have a lot of crisps out in advance.
• lots of bread rolls on the table.
• Get people seated and you are going to have to plate it up whether you like it or not. (the meat as a minimum, but i'd have someone help you and do it all so you can overload them with carrots and potatoes)
• Plate your DB and SIL last so that everyone gets a "head start" so to speak....if they complain while serving say theirs are coming and point out the bread rolls....

Regarding your mother's house I legit dont even know how you can even fit that much food on one plate....

Serve up the expensive stuff i.e. the meat etc and have potatoes, and veg buffet style.

Plate it up in the kitchen. He can't take the food for everyone else. That is so rude. Fine at the end to eat any left overs and have enough food for everyone.

Totally.

🙄🙄🙄

Very 🤣🤣🤣
