Preheat the oven to 400°F while lining a baking tray with parchment.
Over medium-high flame, season and brown the beef. Once done, transfer to a bowl.
In the residual beef fat, sauté potatoes and onions for 6-8 minutes. Add butter if needed.
Introduce garlic, rosemary, and thyme to the skillet, cooking until aromatic. Mix in Worcestershire sauce.
Combine the veggies with the beef, seasoning to preference. Let it cool to room temperature.
