Philly Steak Casserole Ingredient Notes
- Olive Oil
- Beef - we like to use thin sliced shaved steak that comes already sliced. You can also thinly slice raw steak like Ribeye.
- Onion - any variety will work, yellow onion, red onion, or sweet onion
- Bell Pepper - we used a mix of colored bell peppers for color, any will work whether you're using green bell peppers, red, yellow, or orange.
- Crimini mushrooms - common button mushrooms work great too!
- Provolone cheese - Provolone cheese is the classic cheese used for Philly cheese steak casserole, but other white cheeses such as mozzarella, white cheddar, or Colby Jack works great too. You can use either provolone cheese slices or shredded provolone cheese.
- Cream cheese - full fat for best flavor or if you're making a keto Philly cheesesteak casserole recipe, buying lower-fat cream cheese increases the carbs too
- Beef broth
- Worcestershire sauce
- Garlic Salt - if you don't have garlic salt on hand, use a mix of salt and garlic powder
- Black Pepper - fresh ground black pepper
Recipe Variations
A ground beef mixture can be used in place of the thinly sliced beef.
If you don't care for provolone cheese, or simply want to try other cheeses, Monterey Jack, Colby, or even Cheddar are all great options!
Equipment
For the Philly cheesesteak casserole, you are going to need a large skillet, preferably one that is oven-proof. If your skillet is not oven-proof, you will also need a 9x13 baking dish or large casserole dish.
Diet Adaptions
- Gluten-Free - Use Worcestershire sauce that doesn't have gluten or swap for coconut aminos.
- Keto - To make a keto Philly cheesesteak casserole, use full-fat cream cheese to keep carbs down and don't buy pre-shredded cheese since it adds starch and extra carbs.
How to Make Keto Philly Cheesesteak Casserole
Now that you know what you need, let's get to cooking this quick and easy Philly cheesesteak casserole recipe! To summarize the process, you'll need to brown the ground beef mixture over medium-high heat, add the green pepper and veggies, season it with spices like garlic powder and then pop it in the oven to 350 degrees to finish cooking.
Prep Ingredients
Thinly slice 2lbs of steak.
Slice 1 small onion, 2 bell peppers, and 2 cups of crimini mushrooms.
Shred or slice 2 cups of provolone cheese.
Preheat your skillet over medium-high heat with 1 tablespoon of oil.
Preheat your oven to 350 degrees F.
Stovetop
In a preheated skillet, add the sliced steak. Season with 1 teaspoon garlic salt and ½ teaspoon pepper and cook until browned.
Remove the cooked steak from the pan and set aside, leaving 2 tablespoon of grease in the skillet. (If there is not enough grease remaining in your pan add a little extra oil.)
Add the sliced onions, peppers, and mushrooms and cook until soft.
Add 1 teaspoon of Worcestershire, ½ cup beef broth, and 4 oz cream cheese to the pan. Stir to combine.
Heat until cream cheese is melted then add the beef back into the pan.
***Note: If your skillet is not oven safe, transfer the entire dish to an oven safe 9x13 baking or casserole dish.
Top with 2 cups of provolone cheese.
Bake to Melt Cheese
Place the entire dish in your preheated oven and bake for 15-minutes until the melted provolone cheese slices or shreds are bubbly and golden brown.
Additionally, you can broil for 2-3 minutes for a crispy top.
Serve immediately. Enjoy!
Cheesesteak Casserole Recipe Tips
- For steak, we prefer thin sliced sirloin tip steak, ribeye, or shaved beef. Do not use stew meat as it will be tough.
- The thinner your steak the faster it will cook and the more tender it will be.
- Keep an eye on your steak as it cooks and remove it from the pan as soon as it is done.
- We use garlic salt and pepper, but feel free to utilize your favorite steak seasoning.
- Baking is solely to melt the provolone cheese slices. If you prefer, you can top your skillet with a cover and heat over the stovetop to melt instead of baking the cheese until golden brown.
Common Questions
What to Serve with Philly Cheese Steak Casserole?
You can serve Philly cheesesteak casserole recipe with salad or cauliflower rice to keep the entire dish low-carb and keto-friendly. Serve with rice or rolls for those who don't worry about carbs or gluten.
Can This be Frozen?
Cream cheese doesn't freeze well and turns crumbly after defrosting. If you want to freeze the Philly cheesesteak casserole, combine all ingredients except the cream cheese and cheese. After defrosting, reheat the casserole in a skillet, add the cream cheese, and then melt the provolone on top.
How do you store leftovers?
Store any leftover Philly cheesesteak casserole in a covered dish in the fridge for 4-5 days. This makes a great recipe as part of a weekly meal plan or to use leftover for meal prep lunches.

Yield: 6
Prep Time: 15 minutes
Cook Time: 30 minutes
Total Time: 45 minutes
An easy and hearty Philly cheesesteak casserole that's full of flavor yet without the bun. Not only does it cook in 30 minutes, but it's gluten free, low carb, and keto friendly too.
Ingredients
- 1 tablespoon olive oil
- 2 lb thinly sliced beef
- 1 small onion
- 2 bell peppers, sliced
- 2 cups button or baby bella mushrooms, sliced
- 2 cups shredded provolone
- 4 oz cream cheese
- ½ cup beef broth
- 1 teaspoon Worcestershire sauce
- 1 teaspoon garlic salt
- ½ teaspoon ground black pepper
Instructions
- Preheat the oven to 350F. In a large skillet (ideally cast iron or oven proof), heat the olive oil over medium-high heat.
- Add the thinly sliced beef, garlic salt, and pepper and cook it until browned. Remove from the pan and set aside, but leave about 2 tablespoon of grease in the skillet to cook the vegetables in. If there isn't enough grease left, just add a little more oil to the pan for the veggies.
- Add the sliced bell peppers, onion, and mushrooms to the skillet. Cook until softened.
- Add the Worcestershire sauce, beef broth, and cream cheese to the pan and combine. Heat through until the cream cheese is melted.
- Add the beef back to the pan and combine all ingredients. If you don't have an ovenproof skillet that's large enough to hold all of the ingredients, transfer the mixture to a 9x13 pan and combine it in there.
- Sprinkle with shredded provolone cheese or provolone slices.
- Bake 15 mins until heated through. Broil for 2-3 mins if prefer crispy cheese on top. Garnish with chopped fresh parsley. Enjoy!
Notes
We used thinly sliced sirloin tip steak, ribeye or shaved beef are great choices. Don't use sliced stew meat since it's a tough cut. Ground beef is a great substitute for thinly sliced steak, plus its an inexpensive option.
Traditional Philly cheese steak is thinly sliced steak and onions, we've used an adaption that's more common in our area which adds bell peppers and mushrooms.
Cook the steak and veggies in batches and transfer to a 9x13 pan to finish baking if you don't have a large ovenproof skillet.
Since the mixture is already heated and you're just cooking until the cheese melts, you can also leave the mix in the skillet, turn the burner down to medium low and cover the pan. Cook through until the cheese is melted.
If you don't have provolone, Monterey Jack is a good substitute.
Feel free to use a variety of colored bell peppers.
