Ingredients
- 2 pounds ground beef
- 1 tablespoon olive oil
- 1 medium green bell pepper, diced
- 1 medium red bell pepper, diced
- 1 medium onion, sliced
- 8 ounces mushrooms, sliced
- 3 cloves garlic, minced
- 8 ounces cream cheese, softened
- ½ cup heavy whipping cream
- 1 teaspoon Worcestershire sauce
- 1 teaspoon onion powder
- 1 teaspoon garlic powder
- ½ teaspoon smoked paprika
- Salt, to taste
- Black pepper, to taste
- 1½ cups shredded mozzarella cheese
- 6 slices provolone cheese
- Fresh chopped parsley for garnish (optional)
Instructions
Step 1: Prepare the Oven
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish with cooking spray or butter.
Step 2: Brown the Beef
Heat olive oil in a large skillet over medium-high heat. Add the ground beef and cook until fully browned, breaking it apart with a wooden spoon as it cooks.
Drain any excess grease if necessary.
Step 3: Cook the Vegetables
Add the sliced onions, mushrooms, and diced bell peppers to the skillet.
Cook for about 6–8 minutes until the vegetables become tender.
Stir in the minced garlic and cook for another minute until fragrant.
Step 4: Make the Creamy Sauce
Reduce the heat to low.
Add the softened cream cheese and heavy cream.
Stir continuously until the cream cheese melts into a smooth, creamy sauce.
Mix in Worcestershire sauce, onion powder, garlic powder, smoked paprika, salt, and pepper.
Cook for another 2–3 minutes until everything is well combined.
Step 5: Assemble the Casserole
Transfer the beef mixture into the prepared casserole dish.
Spread it evenly.
Top with shredded mozzarella cheese.
Arrange the provolone cheese slices over the top for a classic Philly cheesesteak finish.
Step 6: Bake
Bake uncovered for 20 minutes or until the cheese is melted, bubbly, and lightly golden around the edges.
Step 7: Serve
Remove from the oven and allow the casserole to rest for 5 minutes.
Sprinkle with fresh parsley before serving if desired.
Serve hot and enjoy every cheesy bite.
Tips for Success
- Use lean ground beef for less grease.
- Ribeye steak can replace ground beef for a more authentic Philly cheesesteak flavor.
- Add sliced jalapeños if you enjoy extra heat.
- Freshly shredded mozzarella melts more smoothly than pre-shredded cheese.
- Allow the casserole to cool slightly before serving for cleaner slices.
Storage
Store leftovers in an airtight container in the refrigerator for up to 4 days.
Freeze individual portions for up to 3 months.
Reheat in the microwave for 2–3 minutes or warm in a 350°F oven until heated through.
