Ingredients:
- 1 Tbsp Neutral Cooking Oil (Canola or Vegetable)
- 1 Tbsp Unsalted Butter
- 1 Large Yellow Onion, thinly sliced
- 1 lb Thinly Sliced Beef Ribeye or Sirloin steak
- 1 tsp Kosher Salt, divided
- ½ tsp Freshly Ground Black Pepper
- 1 tsp Worcestershire Sauce (optional)
- ½ cup Beef Broth (low sodium)
- 4 oz Sharp Provolone Cheese, diced finely or cut into small strips
- 2 oz Low-Moisture Mozzarella Cheese, shredded
- 12-14 Standard Egg Roll Wrappers
- 1 Large Egg, beaten lightly (for egg wash/sealer)
- 3 cups High Smoke Point Oil (For Frying) OR Non-stick cooking spray (For Baking/Air Frying)
Instructions:
- Sauté Aromatics: Heat oil and butter in the skillet over medium heat. Add the sliced onions and a pinch of salt. Cook slowly, stirring frequently, until onions are soft and deeply caramelized (about 10 minutes). Remove onions and set aside.
- Cook Steak: Increase heat to medium-high. Add the thinly sliced steak to the hot skillet, seasoning with remaining salt, pepper, and Worcestershire sauce (if using). Cook quickly until browned (about 3-4 minutes).
- Deglaze and Finish: Add the beef broth and scrape up any flavorful bits from the bottom of the pan. Cook until the broth is almost completely absorbed.
- Combine and Cool: Remove the skillet from heat. Stir in the caramelized onions, diced Provolone, and shredded Mozzarella. Mix gently until the cheese just begins to melt. Transfer the mixture to a bowl and chill in the fridge for 15 minutes, as the filling must be cooled before assembly.
- Assembly Prep: Lay out the cooled egg roll wrappers on a clean surface, oriented like a diamond. Place about 2-3 Tbsp of the cooled filling just below the center of the wrapper. Pull the bottom corner up and over the filling, tucking the point underneath the mixture.
- Seal Sides: Fold the left and right corners inward, meeting in the middle like an envelope. Starting from the bottom, roll the wrapper tightly toward the remaining top corner.
- Roll and Seal: Brush the top corner thoroughly with the egg wash (beaten egg) and press firmly to seal the roll completely. A tight roll is paramount to a successful fry.
- Deep Fry Method: Heat the oil in a heavy-bottomed pan to 350°F (175°C). Carefully place 3-4 egg rolls into the hot oil. Fry for 3-5 minutes, turning occasionally, until deep golden brown and crispy. Drain and season immediately with salt.
- Baking/Air Fryer Method: Preheat oven to 400°F (200°C) or air fryer to 375°F (190°C). Lightly spray the assembled egg rolls with cooking spray. Air fry for 8-10 minutes, flipping halfway, or bake on a wire rack for 15-20 minutes, flipping halfway.
- Serve: Allow the Cheesy Philly Cheesesteak Egg Rolls to cool slightly for 5 minutes before serving (the filling will be molten hot). Slice diagonally and serve immediately with dipping sauce.
