"Squash casserole". No idea what's in it but that's what he called it.
It is, my mom used to make it, Im kinda gonna defend it because I think its the nicest looking and probably best tasting thing on there. But iceberg salads with huge chunks of shitty tomato and some bagged coleslaw and 2 qts of dressing are a sure sign a place sucks.
Its an old 1950s 'handwritten index card recipe collection cookbook' era dish. As far as Church potluck dishes go, its quick and easy and actually not too bad or unhealthy although Im sure some people make it that way. (I googled it and it seems like people are bringing 'Paula Deen' into it and fucking it up adding mayo or sour cream/cream of soup, so there you go). But
You boil like 1-2 lbs of sliced yellow or paddypan squash and a diced onion until theyre soft (you could probably saute them too until theyre soft enough to mash), drain & mash them with a potato masher, mix in an egg, salt and pepper, maybe garlic powder, breadcrumbs (mom crushed up saltines), and I think a cup of cheddar, then press it into a pan that its not more than a couple inches thick and bake it until its 'casserole'. For the last 15 minutes of cooking, you pull it out and top it with cheese or more breadcrumbs or both, cheese with breadcrumbs on top and put it back in til it browns and isnt too soggy.
Those midcentury recipes can be way worse. I could imagine Jack or Tammy endorsing this because its hard to fuck up, especially if you use decent ingredients, since its simple--quality matters. It may be 'too bland' to people though if theyre used to 'new gastronomic' versions of these old dishes but idk with things like this I think some of them are better kind of plain. Same with cornbread frankly, its just cornmeal, buttermilk, an egg, salt & baking soda, maybe some baking powder.
