Would be the typical French way of cooking Côte de bœuf (Beef -Rib).
Sear it and then in the oven.
Scout - your fake Italian is a lousy cook : Don't boil the potatoes before you put a herb mix on it, taters will be tasteless
and either only one herb at the time (rosemarin) or Herbes de Provence. Less heat and more oven will get you the right texture.
Pre-boiling is just how restaurants will do it to save time - the only reason why restaurant food tastes "better" is an obscene amount of seasoning (especially salt) and natural or nature-identical flavor enhancers. Below the "gastronomical" cooks who are really good anyone
who likes to cook could do better than what you'd get in 99 percent of the restaurants. Anybody remembers grandmother's cooking ?
Took a lot of time and that's the secret. The meat that lousy Luigi used wasn't great to begin with, you don't salt it before you sear it, which he didn't do anyway - he burnt it coal black, that's not crusty but cancerous...
He really shoud have been beaten with a wet rag for the "sauce" : Parsil with stems, cooked yoke, capres and anchovis
