Ingredients

For a 6–8 serving casserole, you will need:

1 lb (450 g) thinly sliced beef (ribeye or sirloin works best)
1 medium onion, thinly sliced
1 green bell pepper, thinly sliced
1 red bell pepper, thinly sliced
2 cloves garlic, minced
2 tbsp olive oil
1 tsp salt
½ tsp black pepper
½ tsp paprika (optional for a smoky kick)
1 cup shredded provolone cheese
1 cup shredded mozzarella cheese
½ cup cream cheese (softened)
1 cup milk (whole or 2%)
4 large eggs
2 cups cubed bread (day-old bread works well)
1 tsp Worcestershire sauce (optional, for depth of flavor)

Step-by-Step Instructions

Step 1: Preheat and Prepare

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish lightly with butter or nonstick spray.

Step 2: Cook the Beef and Vegetables

Heat olive oil in a large skillet over medium-high heat.
Add the sliced onions and bell peppers, and sauté for about 4–5 minutes until they start to soften.
Stir in the garlic and cook for another 30 seconds until fragrant.
Push the vegetables to one side of the pan and add the beef slices. Cook until just browned (about 4–6 minutes).
Season with salt, pepper, and paprika. Mix everything together and remove from heat.
