got a 4lb pork butt roast marinating in the fridge in a chimichurri sauce i made. i want to roast this in the oven. should i wrap the whole pan in foil and cover it for part of the roast? i was thinking 2 hours covered with foil then add potatoes and onions to the pan, roast covered for one hour and then uncover for last hour. all at around 350 degrees.
what do you guys think?
