Ingredient Guide

Texas Toast
Thick and buttery with a crispy edge and soft interior, Texas toast is the perfect foundation for this dish. It holds up well under the juicy filling and brings essential garlic flavor. If needed, substitute with thick-cut bread brushed with garlic butter.

Beef Cuts (Ribeye or Sirloin)
Thinly sliced ribeye is ideal for its marbling and tenderness, but sirloin is a great leaner alternative. Whichever cut you use, slicing it very thin ensures a tender bite and even cooking. To make slicing easier, partially freeze the meat for about 20 minutes beforehand.

Peppers and Onions
Green bell peppers and sweet onions bring balance, texture, and sweetness. They break up the richness of the meat and cheese while adding color. Red or yellow bell peppers are also great choices for a milder, sweeter flavor.

Cheese
A combination of provolone and mozzarella creates a creamy, flavorful topping. Provolone gives the authentic Philly cheesesteak flavor, while mozzarella provides stretch and creaminess. Want to change things up? White American or cheddar can be added for a stronger taste.

Worcestershire Sauce
Just a dash adds a deep, savory boost to the beef and vegetables. If you don’t have it, soy sauce can be used, though it’s slightly saltier.

Basic Seasonings
Salt, pepper, and garlic powder are all you need to season the filling. Add a sprinkle of red pepper flakes if you want a little spice, or smoked paprika for extra depth.

Step-by-Step Cooking Instructions

1. Preheat the Oven & Toast the Bread
   Preheat your oven to 375°F. Place Texas toast slices on a baking sheet in a single layer and bake for 5–7 minutes, just enough to crisp the edges. This keeps them from turning soggy once layered in the casserole.

2. Cook the Steak
   Heat a tablespoon of oil in a large skillet over medium-high heat. Add the thinly sliced beef and cook for about 3–4 minutes until just browned. Remove the steak and set aside—don’t overcook, as it will finish baking in the oven.

3. Sauté the Vegetables
   In the same skillet, add a bit more oil if needed and toss in the peppers and onions. Cook over medium heat for 6–8 minutes, stirring often, until they begin to caramelize. Stir in Worcestershire sauce, garlic powder, salt, and pepper. Return the steak to the pan and stir everything together.

4. Build the Casserole
   Grease a 9×13-inch baking dish lightly. Arrange the toasted Texas toast slices across the bottom. Evenly spoon the steak and pepper mixture on top. Lay provolone cheese slices over the filling, then sprinkle shredded mozzarella over everything.

5. Bake
   Bake the dish uncovered for 20–25 minutes, or until the cheese is fully melted and bubbling. For a browned, crispy topping, broil for 2–3 minutes at the end, but keep a close eye on it.

6. Rest & Serve
   Let the casserole sit for 5 minutes before slicing and serving. This makes it easier to portion and allows the layers to settle.

Helpful Tips, Substitutions & Flavor Variations

• Make-Ahead Option: The steak and vegetable filling can be made a day in advance and refrigerated. When ready to serve, toast the bread, assemble, and bake.

• Different Cheeses: Swap mozzarella for Monterey Jack or a sharp cheddar if you prefer stronger flavors.

• Add Mushrooms: Sautéed mushrooms make a delicious, earthy addition that complements the beef.

• Spicy Kick: Add sliced jalapeños or a few dashes of hot sauce to the beef mixture if you like heat.

• Gluten-Free Friendly: Use your favorite gluten-free garlic bread or thick-sliced gluten-free bread.

• Lower-Carb Version: Skip the toast and layer the beef, veggies, and cheese in a casserole dish for a skillet-style bake.

Serving Ideas

This dish is filling enough to serve as a main course on its own, but sides can turn it into a well-rounded meal. Try a crisp green salad with a tangy vinaigrette or roasted vegetables like broccoli or carrots. For heartier options, serve alongside mashed potatoes, baked fries, or sweet potato wedges.

It’s a perfect pick for casual weeknight dinners, weekend gatherings, or potlucks. Leftovers reheat well and make a satisfying lunch the next day.

Pair it with a cold drink like beer, soda, or iced tea for a classic diner-style experience.

Nutrition Notes

This is a rich, comforting dish, but it can be adjusted to meet different dietary needs. Choosing leaner cuts of steak and reduced-fat cheeses can reduce the fat and calorie content without losing flavor.

Adding more vegetables is a great way to increase fiber and nutrients. Try tossing in spinach, mushrooms, or even chopped zucchini to stretch the filling and boost nutrition.

This bake is high in protein and very filling, making it satisfying in smaller portions as well.

Frequently Asked Questions

1. Can I swap steak for ground beef?
Yes! Ground beef works just as well in this recipe. Cook it thoroughly, season it, and drain the fat before layering into the casserole.

2. Can I freeze the assembled dish?
Definitely. Build the casserole, cover it tightly, and freeze before baking. When ready to use, thaw it overnight in the fridge, then bake as instructed, adding extra time if needed.

3. What’s the most authentic cheese to use?
Provolone is the traditional choice for Philly cheesesteaks. To make it even more authentic, you can blend in white American cheese or top with Cheez Whiz.

4. How do I prevent the toast from getting soggy?
Pre-toasting the bread before assembling the casserole is key. It creates a barrier so the bread doesn’t soak up too much moisture.

5. Is there a vegetarian option?
Absolutely. Replace the steak with sautéed mushrooms and extra vegetables. You can also add a plant-based protein or meat substitute to mimic the texture of steak.

6. How should leftovers be stored and reheated?
Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the oven or toaster oven for best texture. The microwave works, but the toast will soften.

7. What can I use instead of Texas toast?
Thick slices of bakery-style bread like Italian or sourdough brushed with garlic butter work great. Just be sure to toast them briefly before layering.
