Ingredients Breakdown: What You’ll Need

The secret to an authentic, mouthwatering Philly Cheesesteak Casserole lies in high-quality ingredients.

1. Protein Choices

• Ribeye steak (the most authentic and flavorful cut)
• Ground beef (a budget-friendly alternative)
• Shaved steak (pre-cut for convenience)

2. Vegetables

• Bell peppers (green, red, or yellow for a balance of sweet and earthy flavors)

5. Binding Agents

• Eggs (help hold the casserole together)
