Philly Cheesesteak Casserole

For the Filling:

• 1½ lbs (680g) ribeye or sirloin steak, thinly sliced or chopped
• 1 tbsp olive oil
• 1 large onion, thinly sliced
• 1 green bell pepper, thinly sliced
• 1 red bell pepper, thinly sliced
• 2 cloves garlic, minced
• 1 tsp Worcestershire sauce
• Salt & black pepper to taste

For the Topping:

• 2 cups (8 oz) shredded provolone cheese (or Cheez Whiz for authenticity!)
• Optional: ½ cup shredded mozzarella for extra melt
• Optional: Sliced hoagie rolls on the side for dipping

💡 Pro Tips:

• Freeze steak 30 mins before slicing—it makes thin cuts easier.
• Don’t overcrowd the pan when browning beef—sear in batches.
• Use freshly shredded cheese—pre-shredded won’t melt as smoothly.

Step-by-Step Instructions (Savory, Cheesy, Foolproof)

1. Sear the Beef

• Heat oil in a large skillet over medium-high heat.
• Sear beef in batches 2–3 minutes per batch until browned (it will finish cooking in oven). Remove; set aside.

2. Sauté Veggies

• In same skillet, add onions and peppers. Cook 8–10 minutes until soft and caramelized.
• Add garlic and Worcestershire; cook 1 more minute.
• Return beef to skillet; mix well. Season with salt and pepper.

3. Assemble & Bake

• Spread mixture evenly into a greased 9x13-inch baking dish.
• Top with provolone (and mozzarella, if using).
• Cover with foil; bake at 375°F (190°C) for 20 minutes.
• Uncover; bake 5–10 more minutes until cheese is bubbly and golden.

4. Serve Hot

• Let rest 5 minutes. Serve with hoagie rolls, garlic bread, or a simple green salad.

Make-Ahead & Storage Tips
