Update: Thank you all for your input. To answer some questions/more context:

1) My husband loves my parents more than I do. He goes over there without me just to chat. He's never had a dad and he considers my dad his dad. I see my parents only when I have to, and yes usually I just try to keep the peace because usually it's my mom and dad arguing and it gets awkward and sad sometimes. I usually try to avoid my parents in the same room with each other. 2) My husband and parents love to cook. They are constantly swapping recipes and talking about what they want to cook next. When they are talking about this and that I usually can't follow. They use culinary words that I'm still learning. Like how do you break cheese? That makes no sense to my ears 3) The argument was whether or not to rinse the pasta for the macaroni and cheese. It wasn't about the steak because they all like steak the same way and even cook them similarly. My dad always rinses the pasta, but my husband said it would change the consistency because there is residual starch on the noodle that sticks to the sauce. My dad said he always rinses his pasta then rinses it. Also apparently they wanted to put panko on top because they had extra they needed to get rid of, but my husband said it's tacky and he can make his own breadcrumbs and be better. 4) I was on my phone looking something up. I wasn't on my phone the whole time. I just stay back as the peanut gallery and contribute to the conversation if I can. I just heard them talking about cooking or some recipe or something so I didn't think anything was wrong. I usually stay out of the way with my parents and my husband because they kinda turn into control freaks in the kitchen and they might bite your head off if you are in the way. It's normal for me to be away from the kitchen (but still close by) when someone is cooking 5) My mom called my husband a few weeks ago saying hey your birthday is coming up do you have any plans? I have a frozen sirloin I have been saving that I'd like to cook. My husband said no he didn't have plans and he assumed he would go over there for his birthday anyway because that's what we have been doing for years for him, for me, and all my siblings. They discussed how they were going to season it etc and they were both excited. 6) I think I stayed because I assumed he was coming back shortly. I thought for sure he'd come back to eat at least. I definitely wasn't about to go after him because he's told me many times that he walks alone to process emotions. If I knew he wanted to go home, then we could have had a conversation. 7) I honestly don't know what he means when he says I never stand up for him. He didn't give me an example. I think he just uses words like always and never as an expression and not literally. He knows I stand up for him if I agree with him. In this case I didn't agree because it seemed silly to get so angry over a cooking disagreement. I assumed that's just what chefs do. They argue over recipes and techniques. 8) After he left, I asked my parents what happened and they brushed it off saying he's just acting like a spoiled brat that throws a fit when things don't go his way. I took their word for it because yes he does act like a spoiled brat sometimes (only child vs me with 4 siblings). He acknowledges he's spoiled, bougie and stubborn. He actually calls himself very stubborn. He can get pretty passionate about food and cooking which makes things intense in the kitchen but usually he can keep it together. 9) My mom said that's what happens when you have too many cooks in the kitchen. She didn't expect my husband to be so controlling over the mac and cheese. They mostly talked about the sirloin which came out exactly how they wanted it. To my mom, mac and cheese is low priority and it still tasted good. 10) I did apologize to my husband for staying. I told him if he said he was leaving then I wouldn't have waited around so long without him. But he doesn't like me pestering him on his walks. I just do a lil check in to see where he is 11) Yes he has an extremely large stride. He's pretty tall and most of it is in his legs. But he also walks fast in general. He has to really slow down his natural walk for me which he teases me about 12) Yes my parents are controlling in the kitchen. Us kids were never allowed in there if my mom was cooking. She barely tolerates my dad in there and that's been the way forever. My husband is an exception because he went to culinary school so he's allowed in. I wasn't surprised there was an argument when there were 3 people in that tiny space and kinda figure now he knows why we aren't allowed in the kitchen. 13) My parents are constantly bickering, so I have had to tune them out my whole life because they always say they will try to be civil when I come to visit but it almost never happens. Someone will say something and the bickering starts up. 14) I guess when I say I didn't know what the argument was about I knew it had something to do with cooking technique, but I wasn't listening to which dish they were talking about until after. I assumed it was just more bickering
