Tips
Here are a few tips on how you can make this Philly Cheesesteak Casserole turn out perfect!
- How to Slice Sirloin: Slicing the sirloin steak thinly and against the grain will give you a tender texture in the casserole.
- Adjust the Seasonings: You can add more or less salt, pepper, or Worcestershire sauce to make it just how you like it.
- Marinate: For extra depth of flavor, try marinating the steak in the Worcestershire sauce for a few minutes before cooking.
- Time Savers: To save time, you can use pre-sliced mushrooms and pre-minced garlic from the grocery store. Then you can whip this up even faster!
- Preheat the Skillet: Preheating the cast iron skillet before cooking the steak will help create a nice sear and then keep the meat nice and juicy.
Variations and Substitutions
Do you love this so much you want to make it all the time? I get it! Here are some variations and ways to change this up so that you can have it often and it’s different every time!
- Change the Meat: Substitute the sirloin steak with thinly sliced chicken breasts or chicken tenders for a delicious chicken version of the casserole.
- Make it Vegetarian: Skip the meat and add more veggies like zucchini, broccoli, or spinach for a meat-free option.
- Add Carbs: Add cooked rice or your favorite pasta to the casserole for a hearty and filling twist.
- Change up the Cheese: Experiment with different cheese combinations. Try using mozzarella, Swiss, or gouda in place of the provolone or pepperjack cheese.
- Add Rolls on Top: Instead of provolone cheese, top the casserole with slices of Philly rolls or hoagie rolls to mimic the traditional sandwich experience.
- Make it Spicy: Add some diced jalapeños or crushed red pepper flakes to the mix for an extra kick of heat.
- Have it for Breakfast! Make a breakfast version by adding scrambled eggs to the casserole and then serve it with toast or English muffins.
