He’s making me feel guilty for not eating the food he made me. Should I be worried this is a red flag?

I’ve been seeing a guy now for about 5 months. I go to his house every weekend and he always cooks for me. He’s always expressed how he likes to cook food and likes to make me different things. I love his cooking and tell him every week. But his portion sizes are too much. I’ve told him a few times that I struggle to eat the food because of the amount that’s on the plate. He’s even admitted himself he goes overboard with the portion sizes. Last weekend he made me a cottage pie. One of him and one for me. It could have fed a family of 4. I only managed to eat just under half of it. That night he woke me from my sleep to point out that I didn’t eat it all and I mustn’t have liked it. I told him I enjoyed it, but I was too full to finish it. The next day he made a comment about how he had to throw away so much food. While I appreciate the effort he goes through to cook for me, I’ve told him I can’t always finish meals that are too large for me. All week he’s mentioned me wasting his food. Then today when I’m supposed to go to his house, he’s brought it up again. Telling me he’s worried what to make me and he’s ‘given up trying to think what to cook for me as it just gets thrown in the bin’. He brought up a lasagne he made me over a month ago which I couldn’t finish then either from being too full. I’ve repeatedly told him I like his food, to which he replied ‘don’t patronise me’ and ‘that’s bullshit’. I’ve apologised for not finishing his food as well, but it doesn’t seem good enough for him. He just keeps making me feel bad about it. The last messages I’ve sent him I told him I liked his cooking and that he always makes me things I want. He’s read them but not replied. The other night on the phone he was talking about a new dish he wanted to make me for this weekend, but now he’s giving me the cold shoulder about me coming over. All because I couldn’t finish a cottage pie.
