Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

2 lbs ground beef
1 large onion, diced
2 large bell peppers (green, red, or a mix), diced
2 cloves garlic, minced
8 oz cream cheese (1 package)
2 tbsp soy sauce
Salt and pepper to taste
8 oz provolone cheese, sliced
1½ cups shredded mozzarella cheese
1 tbsp olive oil

Directions

Prepare the Oven: Preheat your oven to 350°F (175°C). Spray a 9×13 baking dish with non-stick spray to prevent sticking.
Cook the Vegetables: Heat olive oil in a large skillet over medium heat. Add the diced onions and bell peppers. Cook for 5-6 minutes until they begin to soften. Add the minced garlic and cook for another 30 seconds until fragrant.
Brown the Beef: Add the ground beef to the skillet with the softened vegetables. Season with salt and pepper. Cook, breaking up the beef with a spatula, for 7-8 minutes until the beef is fully browned.
Add Seasonings: Stir in the soy sauce to coat the beef and vegetables, enhancing the flavor of the mixture.
Incorporate the Cream Cheese: Reduce the heat to low. Add the softened cream cheese and stir until it melts completely, coating the beef and vegetable mixture in a creamy sauce.
Transfer to Baking Dish: Once the mixture is well-combined, transfer it to the prepared baking dish, spreading it evenly.
Top with Cheese: Layer the sliced provolone cheese over the beef mixture. Then, sprinkle the shredded mozzarella cheese evenly on top.
Bake to Perfection: Place the casserole in the preheated oven and bake for 20-25 minutes, until the cheese is melted, bubbly, and slightly golden.
Rest Before Serving: Let the casserole rest for 5 minutes before serving. This allows the flavors to meld together and makes it easier to serve.
