Ingredients

Scale

Meat and Vegetables

2 lbs ground beef (80/20 fat ratio preferred)
1 large onion, diced (yellow onion recommended)
2 large bell peppers, diced (green, red, or mixed)
2 cloves garlic, minced (fresh)

Dairy & Cheese

8 oz cream cheese, softened to room temperature (full-fat preferred)
8 oz provolone cheese, sliced (torn into smaller pieces)
1½ cups mozzarella cheese, shredded

Other

2 tbsp Worcestershire sauce (Lea & Perrins recommended)
1 tbsp olive oil for cooking
Salt and pepper to taste

Instructions

Preheat Oven and Prepare Baking Dish: Preheat your oven to 350°F (175°C) and spray a 9×13 inch baking dish with non-stick spray to ensure the casserole doesn’t stick and cooks evenly.
Sauté Vegetables: Heat olive oil in a large skillet over medium heat. Add diced onions and bell peppers, cooking for 5-6 minutes until they soften and become fragrant. Add minced garlic and cook for another 30 seconds while stirring constantly to avoid burning.
Cook Ground Beef: Add ground beef to the skillet, breaking it apart with a spatula. Season generously with salt and pepper. Cook for 7-8 minutes until the beef is fully browned with no pink remaining. Drain excess fat if needed to reduce greasiness.
Add Flavor and Cream Cheese: Stir in Worcestershire sauce to coat the meat mixture evenly. Reduce heat to low and add softened cream cheese, stirring continuously until it melts completely and creates a rich, creamy texture.
Assemble Casserole: Transfer the creamy beef and vegetable mixture to the prepared baking dish and spread evenly. Layer torn provolone cheese pieces over the top followed by a generous layer of shredded mozzarella cheese for a perfect melty finish.
Bake: Bake the casserole in the preheated oven for 22-25 minutes until the cheese is melted, bubbly, and slightly golden on top. Remove from the oven and let it rest for 5 minutes to allow flavors to meld before serving.

Notes

Use 80/20 ground beef for the best balance of flavor and moisture.
Softened cream cheese ensures smooth incorporation into the beef mixture.
Drain excess fat from cooked beef to avoid a greasy casserole.
Feel free to add mushrooms or jalapeños for extra flavor and heat.
Store leftovers in an airtight container in the refrigerator for up to 4 days or freeze individual portions up to 3 months.
Reheat in the oven at 325°F until warmed through or use a microwave with a damp paper towel for moisture retention.
Adding fresh cheese on top before reheating helps restore a freshly baked taste.
