Peel and cut your Yukon Gold potatoes into evenly-sized chunks, then place them in a large pot filled with cold salted water. Bring to a boil over medium-high heat and cook for 15-20 minutes, or until fork-tender.

In a large skillet, heat a tablespoon of oil over medium heat. Add the ground beef, breaking it apart with a wooden spoon. Cook for 5-7 minutes, or until the beef is well browned and no longer pink.

With the cooked ground beef still in the skillet, stir in the Worcestershire sauce and beef broth, ensuring everything is well combined. Increase the heat slightly and allow the mixture to simmer for about 5-10 minutes, letting it thicken.

Scoop generous portions of the creamy mashed potatoes onto plates, creating a cozy base for the savory flavor. Ladle the rich ground beef gravy over the mashed potatoes.
