AITA for saying the substitutions my boyfriend’s mother wants mean I’m cooking her a different meal to everyone else?

In a cozy kitchen, a woman preps a hearty brisket for her boyfriend and son’s joint birthday bash, picturing a night of laughter and love. Then, her mother-in-law’s call disrupts the vibe, demanding chicken, salad, and boiled veggies instead—no allergies, just picky tastes. When the woman quips about cooking a whole different meal, tempers flare, and the MIL threatens to skip the party unless she gets an apology. Is she wrong to hold her ground?

Hosting family dinners often stirs a pot of expectations and egos. With 70% of Americans reporting family conflicts during gatherings, per a 2023 YouGov poll, this culinary clash feels all too familiar. Her stand against custom orders pulls us into a spicy saga of boundaries, family ties, and the politics of a shared table.

‘AITA for saying the substitutions my boyfriend’s mother wants mean I’m cooking her a different meal to everyone else?’

I've been with my boyfriend for sort of 5 years now and we have a 2 year old son. My son's birthday is 2 days after my boyfriend's so we're having a joint celebratory birthday dinner tomorrow and inviting my boyfriend's parents. I'm making a brisket with some mashed potatoes and roasted veggies.

I felt this was a relatively uncontroversial choice as boyfriend and son love it, and both MIL and FIL eat beef regularly (though IDK if they've had brisket specifically before). However, his mum called me a couple hours ago and asked what I was cooking. I told her.

She asked what brisket was and I told her (which answers the question about them eating it before), and she said 'that sounds lovely, but' and then asked me if I could substitute the brisket for chicken, the mash for a salad, and boil the veg, not roast it.

She always does this, every time, and it's not an intolerance or allergy or anything, it's just a preference (I've checked) and she expects me to make a separate meal just for her. I usually accommodate but I felt that this was ridiculous.. I said 'right, just checking, you are aware that's an entirely different meal?'

MIL says that she doesn't see the issue, so I said it wasn't an issue and I was joking and I'll make it, and she said clearly I had an issue with her request, and I said I don't have an issue, and we went back and forth like that for a bit until she said that she didn't even want to come any more because she felt like her presence was inconveniencing me, before hanging up.

She's now informed my boyfriend that I was rude over the phone, made her feel like a burden, and that she now feels unwanted/unwelcome at his birthday meal tomorrow and won't come unless I call her and apologise for my comment about her wanting a different meal to everyone else.

I agreed to talk to her, but said nothing about apologising. He called her and handed me the phone. FIL picked up and I was nice to him, greeted him, said I'm making brisket and I hope he'll be there and he said of course he will and he can't wait.

He then passed me to MIL who said she was waiting for that apology, and I said that she'd be waiting a long time and that this is her son and grandson's joint birthday so she can attend and eat what I make or she can sit at home and miss all the fun.

Both my boyfriend and his mum say I'm an arsehole. MIL says so because I'm not accommodating her, BF says I don't have to accommodate her but I don't have to be snarky about it, especially as it's his birthday too and he wants her there.. AITA?

Cooking for a family celebration shouldn’t feel like running a diner, but this woman’s MIL treats her like a short-order chef. Planning a brisket feast for her boyfriend and son’s birthday, she faced demands for a completely different meal—chicken, salad, boiled veggies—based on preference, not necessity. Her quip about the “different meal” sparked a feud, with the MIL feeling unwelcome and the boyfriend calling her snarky, despite agreeing she shouldn’t cater to his mother.

This scenario reflects broader issues of family dynamics and boundary-setting. A 2022 Psychology Today article notes 65% of family conflicts stem from unclear expectations (source). Dr. John Gottman, a relationship expert, states, “Respecting boundaries strengthens relationships; ignoring them breeds resentment” (source). The MIL’s pattern of demanding substitutions asserts control, undermining the OP’s role as host.

Dr. Gottman’s insight supports the OP’s refusal to apologize—her comment was a reasonable pushback against entitlement. Her boyfriend’s mixed stance highlights a need for unified boundaries. For solutions, she should calmly restate her menu plans in future, suggesting guests bring dishes to share if they have preferences (e.g., a $10 salad kit from Costco, source). If tensions persist, couples counseling could align her and her boyfriend.

Here’s the input from the Reddit crowd:

Reddit’s reactions sizzle like a hot skillet, with users roasting the MIL’s audacity. Here’s what the community had to say:

teresajs − NTA If your MIL wants to pick the menu, she can make dinner and invite you. You aren't a short order cook.. Thank you for the award, kind stranger!

CopsaLau − NTA never let this woman steamroll you. “No, we will be having what I’ve already planned and purchased for and there won’t be any substitutions. You are welcome to bring something too however, if you’d like to bring a salad for the table.”. Set boundaries.

[Reddit User] − NTA Your MIL tho....wow.......yea it’s inconvenient and rude af to ask the host to make a whole separate meal for you. You don’t owe her an apology and you really need to stop “accommodating” her.

zeusmom1031 − Your MIL is rude and disrespectful. But worse, you BF didn’t stand up for you - that is BIG! No it is HUGE! It’s one thing to have sensitivities but this is very different it sounds like. BF needs to get on board with that asap. He needs to have your back. To me that is the most important issue at hand.. Your house, your menu.

I would have had a hard time not becoming snarky with my DH but that’s not the best way. Like the next time he asked what was for a holiday dinner at your place I’d say, “I don’t know why don’t you ask your Mother?” - But that is not the best way - 😆

Sometimes it helps to be prepared with your responses since you know she will do this - you could always say you already bought the brisket.. Edit: Spelling and grammar - I was not drinking when I originally wrote this....well

Madmax0412 − I'm surprised that not one person here has pointed out the obvious. It's a power play. You said it started small, and escalated until it's reached this point. She has caused you two to breakup a few times in the past.. She is telling you, in her own way, that she is woman #1, and you are #2. Put your foot down. Set boundaries. Bf can decide if wants to cut the apron strings, and man up, or not.. NTA.

Niteynitenurse − I’m no help- I would get a child’s meal takeout for her. NTA.

MikkiTh − NTA She's being ridiculous and no one should have to make a totally separate meal every time she comes over, but especially not you. Your boyfriend can pick her up something from Boston market if he's so concerned

alsbigdeal − NTA The next time she calls and asks for the menu let her know that nothing on the menu is an allergen risk, if thats what she's concern about. No reason to provide specifics, her treatment is very rude and she's out of line. If she wants to dictate her menu she can plan her own party in her own home for her own events.

gem17ini − Then he can cook for mummy

whalewatch247 − Your BF is an a**hole. You are not being snarky. Refuse to engage w her. F**k that. She can eat your food or eat before coming over. The end of it. Break up w him too.
