Ingredients

2 lbs ground beef (80/20 fat ratio preferred)
1 large yellow onion, diced
2 large bell peppers, diced (green, red, or mixed)
2 cloves garlic, minced
8 oz cream cheese, softened to room temperature
2 tbsp Worcestershire sauce
Salt and pepper to taste
8 oz provolone cheese, sliced (torn into smaller pieces)
1½ cups mozzarella cheese, shredded
1 tbsp olive oil for cooking

Instructions

Step 1: Preheat your oven to 350°F (175°C) and spray a 9×13 baking dish with non-stick spray. Heat olive oil in a large skillet over medium heat.
Step 2: Add diced onions and bell peppers to the hot oil. Cook for 5-6 minutes until softened and fragrant. Add minced garlic and cook for another 30 seconds, stirring to prevent burning.
Step 3: Add ground beef to the skillet, breaking it up with a spatula. Season with salt and pepper. Cook for 7-8 minutes until browned with no pink remaining. Drain excess fat if needed.
Step 4: Stir in Worcestershire sauce, coating the meat mixture. Reduce heat to low, add softened cream cheese, and stir until completely melted and creamy.
Step 5: Transfer the beef mixture to the prepared baking dish and spread evenly. Layer torn provolone pieces over the top, then sprinkle with shredded mozzarella.
Step 6: Bake for 22-25 minutes until cheese is melted, bubbly, and lightly golden. Let rest for 5 minutes before serving.

Tips & Variations

Use 80/20 ground beef for juicy, tender results without excess grease.
Tear provolone into smaller pieces to ensure even melting over the casserole.
Add sautéed mushrooms or jalapeños for extra flavor and heat.
Try different cheese combinations like cheddar or Monterey Jack for variety.

Storage

Store leftovers in an airtight container in the refrigerator for up to 4 days. For longer storage, freeze individual portions wrapped tightly for up to 3 months. Reheat in the oven at 325°F until warmed through or microwave covered with a damp paper towel to retain moisture. Adding a sprinkle of fresh cheese on top before reheating restores the just-made flavor.

FAQs

Can I use other types of ground meat?

Yes, you can substitute ground turkey, chicken, or pork, but the flavor and fat content will differ. Using higher-fat meat will give a juicier result similar to traditional cheesesteak.
