Philly Cheesesteak Casserole


  1. Preheat your oven to 375°F (190°C).
  2. Lightly grease a 9x13-inch baking dish or similar-sized casserole dish.

2. Cook the Beef

  1. Heat 1 tablespoon of olive oil or butter in a large skillet over medium-high heat.
  2. Add the beef strips and season with salt, black pepper, and Worcestershire sauce. Cook for 4–5 minutes, stirring occasionally, until browned but still tender. Remove the beef from the skillet and set aside.

3. Sauté the Vegetables

  1. In the same skillet, add the remaining 1 tablespoon of olive oil or butter.
  2. Add the sliced onion and bell peppers. Cook for 5–7 minutes, until softened and slightly caramelized.
  3. Stir in the minced garlic and cook for 1 minute, until fragrant.
  4. Optional: Add sliced mushrooms and cook for an additional 3–4 minutes, until tender.

4. Assemble the Casserole

  1. Spread the cooked egg noodles, rice, or shredded hashbrowns evenly in the prepared baking dish.
  2. Layer the cooked beef and sautéed vegetables over the base.
  3. Sprinkle the shredded cheese evenly over the top.

5. Bake

  1. Bake in the preheated oven for 20–25 minutes, or until the cheese is melted, bubbly, and slightly golden.
  2. Optional: Broil for 2–3 minutes at the end for extra browning (watch closely to avoid burning).

6. Serve and Enjoy

  1. Remove the casserole from the oven and let it cool slightly before serving.
  2. Garnish with fresh parsley for added brightness.
  3. Enjoy every bite of this hearty, cheesy Philly cheesesteak casserole!
  4. Perfect as a standalone meal or paired with a side salad or steamed veggies for a complete feast.

Tips for Success

  • Use Fresh Ingredients: Fresh garlic, herbs, and high-quality cheese make a noticeable difference in flavor.
  • Switch Proteins: Substitute beef with chicken, turkey, or plant-based alternatives for variety.
  • Add Veggies: Stir in spinach, zucchini, or diced tomatoes for added nutrition.
  • Store Leftovers: Store in an airtight container in the fridge for up to 3 days. Reheat gently in the oven or microwave before serving.
