Ingredient spotlight
Ground beef (halal-certified) with 80/20 fat content creates the juiciest, most flavorful base for this casserole. The fat renders during cooking and adds richness without being greasy.
Cream cheese forms the foundation of that signature cheesy sauce. Full-fat cream cheese melts smoothly and creates that silky texture you’re craving from a Philly cheesesteak.
Bell peppers bring authentic steakhouse flavor and add color, crunch, and nutrients. A mix of red and green peppers provides the best visual appeal and taste.
Provolone cheese is the classic choice for authentic Philly flavor. It melts beautifully and creates those gorgeous cheese pulls everyone loves.
Step-by-Step Instructions
1. Preheat and prep your oven to 350°F and spray a 9×13-inch baking dish with non-stick spray. Have all your ingredients measured and ready before you start cooking.
2. Sauté the vegetables by heating olive oil in a large oven-safe skillet over medium heat. Add diced onions and bell peppers, cooking for 5-6 minutes until they start to soften and caramelize.
3. Add the garlic and cook for 30 seconds until fragrant. Garlic burns easily, so keep it moving in the pan and don’t walk away.
4. Brown the beef by adding ground beef (halal-certified) to the skillet with the vegetables. Break it into small pieces with your spatula and cook for 7-8 minutes until no pink remains. Season generously with salt and pepper.
5. Create the sauce by reducing heat to low and stirring in Worcestershire sauce. Add softened cream cheese in chunks and stir constantly until it melts into the meat mixture completely.
6. Add the liquids by pouring in beef broth (halal-certified) and heavy cream. Stir everything together until you have a smooth, creamy sauce coating all the meat and vegetables.
7. Add the cheese by sprinkling shredded provolone and mozzarella evenly over the top. If using a skillet, transfer the mixture to your prepared baking dish first.
8. Bake uncovered for 15-20 minutes until the cheese melts completely and turns golden brown around the edges. Watch closely during the last few minutes to prevent burning.
9. Rest before serving for 5 minutes so the casserole sets and becomes easier to scoop. This also lets the flavors meld together perfectly.
Essential Equipment
Large Oven-Safe Skillet or Cast Iron Pan
Cooking everything in one pan saves time and creates better flavor as ingredients layer together. Cast iron retains heat beautifully and can go straight from stovetop to oven.
9×13 Baking Dish
A glass or ceramic baking dish with high sides holds all the ingredients without spillage. The larger surface area ensures even heat distribution and creates more of that golden, bubbly cheese top everyone fights over.
Sharp Chef’s Knife
Dicing vegetables uniformly ensures they cook at the same rate for perfect texture. A sharp 8-inch chef’s knife makes quick work of peppers and onions without crushing them.
Wooden Spoon (PREMIUM)
A sturdy wooden spoon helps you break up the ground beef (halal-certified) without scratching your cookware. The long handle keeps your hand away from heat while stirring the creamy sauce.

Pro Tips & Tricks
Use 80/20 ground beef for the juiciest results because leaner beef dries out during baking.
Soften cream cheese first by leaving it at room temperature for 30 minutes or microwaving briefly so it melts smoothly without lumps.
Don’t skip the resting time after baking because the casserole needs 5 minutes to set properly for clean slices.
Layer cheese strategically by saving half for the final topping so you get melted cheese throughout plus that gorgeous golden crust.
