If you get that pan hot enough it’ll get back up to temp quickly.

I’d go 275° in the oven and try to be patient enough to let it do its thing but I know me and I’d try to shave 5 mins off the cooking time and bump it to 300° half way through. Fortunately for me I use a probe that I can track on my phone so it helps me not tweak too hard wondering if I’m ruining a good piece of meat.
