How hot/long should I bake my porkchops (bone-in)? I've done a bit of google searching and have gotten mixed results. Is it better to do the low temp slow baking or high temperature but quick? Why?
Depends a lot on how thick they are. Thinner chops would work well with just a high-temp sear under the broiler. Whereas a thicker (for example, a double-cut chop) would be better with a two-temperature process.
I.e. Bake them until they reach the right temperature at 350 or 400, then finish under the broiler for color and flavor.
Same thing applies if you want to pan-sear first, then bake until they get to your desired internal temp.
A really-long and slow cook (AKA 225 for 4 hours) won't work well with a loin-cut, as it doesn't have enough connective tissue to breakdown.
I don't cook the bone-in chops anymore - only the boneless medallions. Typically, I just season with salt and pepper, then quickly sear on the stovetop and stick them in the oven at 350 for 15 to 18 minutes. These numbers are for 1/2" medallions. For 1" medallions, I forego the oven and just cook in pan.
