Ingredients:
- large Russet Potatoes (about 450g each)
- Tbsp Olive Oil
- Tbsp Coarse Salt (Kosher or Sea)
- lbs Boneless Ribeye or Sirloin Steak, very thinly sliced
- medium Yellow Onions, thinly sliced
- small Green Bell Pepper, thinly sliced
- Tbsp Unsalted Butter, divided
- /2 tsp Garlic Powder
- Salt & Black Pepper to taste
- oz Sharp Cheddar Cheese, finely grated
- oz Cream Cheese, softened
- /4 cup Whole Milk
- tsp Worcestershire Sauce
- slices Provolone or American Cheese (Optional topping)
- Tbsp Fresh Parsley, chopped
Instructions:
- Preheat oven to 400°F (200°C). Thoroughly scrub potatoes, pierce deeply several times with a fork, rub lightly with oil and coarse salt. Bake directly on the oven rack or baking sheet for 50–70 minutes until fork-tender.
- While potatoes bake, ensure steak is sliced paper-thin. Season lightly with salt, pepper, and garlic powder.
- Melt 1 Tbsp butter in a large skillet over medium heat. Add sliced onions and peppers. Cook slowly for 10–15 minutes, stirring occasionally, until deeply golden brown and sweet. Remove from skillet and set aside.
- Add the remaining 1 Tbsp butter to the hot skillet. Quickly sear the steak slices in batches for 1–2 minutes until browned. Return all steak and the cooked onions/peppers to the pan.
- Reduce heat to low. Add the cream cheese, shredded cheddar, milk, and Worcestershire sauce to the steak mixture. Stir continuously until the cheeses have melted into a smooth, luscious sauce coating everything. Keep warm on very low heat.
- Once potatoes are cooked, carefully slice them open lengthwise, being careful not to cut all the way through. Fluff the insides aggressively with a fork.
- Spoon the hot Philly steak mixture generously into the centre of each fluffy potato. If using optional topping slices, lay one over the top and place back in the turned-off oven for 2 minutes to melt gorgeously.
- Garnish immediately with fresh parsley before serving piping hot.
