I’m thawing a roast as I type to try this method tomorrow. I’ll put it in the oven before I go to work and hopefully it’ll be mash potato tender when I get home! No onions huh? Just olive oil, salt and pepper, water? I could see why no taters, carrots etc. due to the length of cooking time.
Perhaps you could add potatoes and onions as well as anything else you wish. I just did not want it tasting like beef stew.
