Method
Preparation
- Preheat the oven to 400°F (200°C).
- Wash the potatoes and pierce them with a fork. Place potatoes directly on the rack or on a baking sheet. Bake for about 45 minutes or until tender.
- Slice the baked potatoes in half lengthwise and scoop out some of the flesh, leaving about 1/4–1/2 inch of potato attached to the skin.
- Heat the olive oil in a pan over medium heat. Add sliced onions and cook until caramelized, about 10–15 minutes.
- If your flank steak isn’t cooked, sear it on high heat for 3–4 minutes per side for medium-rare, then let rest and slice thinly against the grain.
Assembly
- Fill each potato skin with sliced steak and caramelized onions. Top with shredded provolone cheese.
- Place the filled skins on a baking sheet and bake at 400°F for about 8–10 minutes, or until the cheese melts and begins to bubble.
- Garnish with chopped chives if desired. Serve warm.
Notes
For faster prep, cook the steak ahead and reheat gently. For extra creaminess, mix reserved scooped potato into the filling.
