How to Make This Casserole

Cooking this dish is straightforward and beginner-friendly. You will sauté some veggies, brown the beef, mix in cheese, and bake until everything is perfectly melted and bubbly. It’s a simple process that anyone can follow, even if you’re new to the kitchen.

What You Need

2 lbs ground beef (80/20 fat ratio preferred)
1 large onion (diced)
2 large bell peppers (green, red, or mixed, diced)
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)
1.5 cups mozzarella cheese (shredded)
1 tbsp olive oil

Cooking Steps

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. Add diced onions and bell peppers to the hot oil, cooking for 5-6 minutes until they start to soften and become fragrant. Add minced garlic and cook for another 30 seconds, stirring constantly to prevent burning.

Next, add ground beef to the skillet, breaking it up with your spatula as it cooks. Season generously with salt and pepper, cooking for 7-8 minutes until completely browned with no pink remaining. Drain excess fat if needed. Stir in Worcestershire sauce and let it coat the meat mixture for enhanced flavor. Reduce heat to low and add the softened cream cheese, stirring until completely melted and creamy.

Transfer the mixture to your prepared baking dish and spread evenly. Layer torn provolone pieces over the beef, then top with shredded mozzarella for that perfect cheese pull. Bake for 22-25 minutes until cheese is melted, bubbly, and lightly golden on top. Let rest for 5 minutes before serving to allow flavors to meld together.

How to Serve This Casserole

This casserole is great on its own, but you can pair it with a simple green salad or some steamed veggies for a nutritious meal. For a little extra crunch, serve it with crispy lettuce or even in lettuce wraps. It’s perfect for family dinners or gatherings with friends!

How to Store This Casserole

To store leftovers, place the cooled casserole in an airtight container and keep it in the fridge for up to 3 days. You can also freeze it for up to 2 months. When you’re ready to enjoy it again, simply reheat in the oven at 350°F until warmed through, or microwave individual servings until hot.
