My MIL Lowered the Oven 100 Degrees to Sabotage My Chicken. Then She Blamed the Delay on My 'Time Management.'

We all know that when you are a guest in someone’s home, you graciously accept what is offered. And when you are the one doing the cooking, even in another’s kitchen, you expect a certain level of respect for your efforts. It is, after all, a gesture of kindness to prepare a meal for others.

However, one woman recently took to the internet to share a story that proves not everyone plays by these simple rules of decency, especially when a little family competition is involved. Her tale of a sabotaged chicken dinner has left many of us shaking our heads in disbelief.

The Incident

A woman, who at the time was working on her doctorate, shared her experience with her former mother-in-law. This mother-in-law was, by all accounts, an excellent cook who made sure everyone knew it. She was described as a “try-hard” who would bake two cakes and a platter of cookies when one dessert would have sufficed, simply to showcase her superiority in the kitchen. This need to constantly one-up others seemed to stem from a deep-seated insecurity, but that understanding didn’t make her behavior any easier to handle.

The trouble began when the woman’s then-husband innocently mentioned that she made a fantastic roast chicken. Before she knew it, she was asked to prepare her signature lemon chicken for a family dinner at her in-laws’ house. Happy to share a dish she loved, she arrived early and prepared two chickens for the family. But as the meal was roasting, she noticed it was taking far longer than usual, and her mother-in-law was starting to show her displeasure with passive-aggressive sighs.

When she went to check on the birds, she discovered the shocking reason for the delay: the oven temperature had been lowered by 100 degrees. She turned it back up, only to find it lowered again the next time she checked. The realization was infuriating. “I was internally like… she actually has been trying to sabotage the dinner… the audacity of that woman,” she wrote.

Her mother-in-law couldn’t stand someone else shining in her kitchen, even for a meal she had been asked to cook. By the time the delicious (but very late) dinner was served, the mother-in-law only complained about the timing, suggesting that “we all need to work on time management.”

The Internet Reacts

The story sparked a flurry of reactions, with readers online quickly taking sides and sharing their own thoughts on the kitchen catastrophe. Most people fell into one of three camps.

Camp 1: The ‘Absolutely Not’ Crowd

Most readers were simply appalled on the woman’s behalf. They couldn’t believe the sheer nerve of the mother-in-law. One commenter expressed what many were thinking about the situation, noting, “The sabotaging is ridiculous! I don’t even think I’d have figured it out.”

Another zeroed in on the husband’s failure to believe his wife’s account, asking, “How stupid could ex be when told that the oven would ‘mysteriously’ lose temperature every time his mommy entered the kitchen?” This group felt the mother-in-law’s behavior was inexcusable, and the son’s denial was just as bad.

Camp 2: The ‘Trying to Understand’ Crowd

While no one defended the mother-in-law’s actions, some readers, including the original poster herself, tried to understand where such behavior comes from. The woman speculated that her mother-in-law’s competitive nature was a result of a life with limited opportunities. She wrote that her mother-in-law “wasn’t even allowed to go to college because she had a brother and the money for college went to him.”

For women of that generation, the home and kitchen were their domains, and perhaps she saw her daughter-in-law’s success—both in academia and in the kitchen—as a threat to her own identity. Still, as the woman wisely noted, “a lot of women in similar situations didn’t end up becoming jealous or controlling people.”

Camp 3: The ‘Petty Revenge’ Crowd

Many readers felt the mother-in-law got what she deserved when the woman later enacted a bit of her own kitchen justice. The mother-in-law was known for sharing recipes with key ingredients or steps left out. So, when she demanded the recipe for a delicious gingerbread cake the woman made, she received the same treatment. The woman gave her the recipe but omitted a secret ingredient.

Readers cheered this move. “I give you loads of props on not giving ex-MIL the correct recipe,” one wrote. “I am a firm believer in treat people the way they treat you.” Another perfectly described the incomplete recipe as the mother-in-law’s “a..hole tax.”

The Etiquette Verdict

Let’s be perfectly clear: sabotaging a meal someone is kindly cooking for you is a shocking breach of etiquette. A kitchen should be a place of warmth and generosity, not a battlefield for domestic dominance. While we can feel sympathy for someone whose insecurities lead them to act out, it is never an excuse for malicious behavior. The role of a host is to make their guests—and anyone cooking in their home—feel welcome and appreciated. To deliberately undermine their efforts is not just rude; it’s deeply unkind and creates a toxic environment for the entire family.
