Step-by-Step Instructions

Prepare Ingredients

Preheat oven to 350°F (175°C). Slice onions and peppers, mince garlic, and grease a 9×13-inch baking dish.

Brown the Beef

Heat olive oil in a large skillet over medium heat. Add ground beef and cook for 5–7 minutes until browned. Drain excess fat if needed.

Sauté the Vegetables

Add onions, bell peppers, and garlic to the skillet. Season with salt, pepper, and smoked paprika. Cook for 5–7 minutes until vegetables are tender but not mushy.

Make the Creamy Mixture

In a bowl, whisk together heavy cream and softened cream cheese until smooth and lump-free.

Combine and Assemble

Pour the cream mixture into the skillet and stir until evenly combined. Transfer mixture to the prepared baking dish.

Top and Bake

Sprinkle provolone and mozzarella evenly over the top. Bake for 25–30 minutes until bubbly and golden.

Rest and Serve

Allow casserole to cool for 5 minutes before slicing and serving.
