Ingredients
I am highlighting just the ones that need further explanation. The complete list is in the recipe card below.
- Ground beef – I recommend using 85-90% lean beef for best flavor. We personally love and trust ButcherBox’s commitment to delivering high-quality grass-fed, grass-finished beef straight to our door. You can certainly use thinly sliced ribeye steak or flank steak for a more authentic Philly cheesesteak.
- Green Bell Peppers – No Philly cheesesteak is complete without bell peppers! They add crunch, color, and a subtle sweetness that pairs well with the beef.
- Yellow Onion – Onions are key for that signature cheesesteak taste. When sautéed, they add a natural sweetness and enhance the overall flavor of the dish.
- Zucchini – Adds more veggies without overpowering the classic flavors. Plus, zucchini brings a slight tenderness that complements the other textures.
- Mushrooms – These bring an earthy, umami richness that makes the casserole taste even more indulgent.
- Full fat cream cheese or Greek yogurt – This is the secret to making the casserole creamy without being heavy. Greek yogurt keeps it lighter, while cream cheese gives it a richer feel.
- Provolone – The classic choice for Philly cheesesteaks, but you can also use mozzarella, white cheddar cheese, or Monterey Jack.
- Seasonings – The combination of smoked paprika, Italian seasoning, and garlic powder provides a well-rounded and delicious flavor profile for the dish.
Step-by-Step Instructions
Step 1: Heat a large skillet over medium-high heat. Add the ground beef and break it up into crumbles as it cooks. once the beef is cooked, carefully remove it from the pan and use a paper towel to wipe away any excess grease remaining in the skillet.
Step 2: Add all the vegetables to the pan and cook over medium-high heat until they begin to soften, about 5 minutes.
Step 3: Stir in the seasonings. Add back the beef and combine.
Step 4: Turn off the heat and stir in cream cheese or yogurt. Add the optional mozzarella cheese.
Step 5: Transfer the ground beef mixture to a 9×13 baking dish.
Step 6: Top the casserole evenly with slices of provolone cheese. Bake for 10-15 minutes until the cheese melts.
Recipe Tips
- Use lean ground beef to prevent excess grease, or drain it well before adding back to the dish.
- Mozzarella cheese is optional but if you are using Greek yogurt instead of cream cheese, I highly recommend adding it.
- I personally love the combination of smoked paprika, Italian seasoning, and garlic powder to enhance the flavor profile of the dish. You can adjust the amount or even leave out or add other typical seasonings for Philly cheesesteak such as Worcestershire sauce or hot sauce.
- If you desire a golden brown crust, broil for 30 seconds to a minute.
- Just like with lasagna, let the casserole sit for at least 5 minutes before serving so it’s easier to scoop.
