Step-by-Step Recipe for One-Cheesy Low Carb Philly Cheesesteak
1. Prepare the Steak and Veggies
- Heat olive oil or butter in a large skillet over medium-high heat.
- Add the sliced onions and bell peppers; sauté for about 5-7 minutes until softened and slightly caramelized. Remove from skillet and set aside.
- In the same skillet, add the thinly sliced steak in a single layer. Season with salt, pepper, garlic powder, and smoked paprika.
- Cook the steak for 2-3 minutes per side until browned and cooked through. Avoid overcrowding the pan; cook in batches if necessary.
- Return the sautéed onions and peppers to the skillet, mixing everything well.
2. Add the Cheese
- Lower the heat to medium-low.
- Layer the provolone slices evenly over the steak and veggies.
- Cover the skillet with a lid to melt the cheese fully, about 2-3 minutes.
3. Assemble and Serve
- If using low-carb wraps or buns, warm them up according to package instructions.
- Spoon the cheesy steak mixture onto your choice of bread substitute or enjoy as-is on a plate.
- For a breadless option, use large lettuce leaves to wrap the filling for a crunchy, refreshing bite.
