Simple Ingredients for Low Carb Cheesesteak Casserole
Ingredients, directions and nutritional information in the printable recipe card at the end of the post.
- Shaved steak | Shaved steak or lean ground beef work well for this recipe. The shaved steak makes it have a texture more like a Philly cheesesteak sandwich, though. I love getting my shaved steak from Trader Joe’s; it’s shaved rib eye and is so tender!
- Butter | A little butter to help saute the veggies and meat. Please use olive oil, if you prefer.
- Onions and peppers | You can’t have a Philly without onions and peppers, so include a medium yellow onion, diced, and two bell peppers. I diced green peppers and red bell pepper for this recipe, but you can use whichever variations you choose.
- Mushrooms | Bring texture and flavor to the recipe with sliced mushrooms. I used Baby Bella’s, but you can also use Crimini or Button mushrooms.
- Garlic | Use fresh garlic cloves, minced, for a bolder flavor, or add one teaspoon of garlic powder.
- Seasonings | Season the meat with onion powder, kosher salt, and black pepper.
- Worcestershire sauce | Worcestershire sauce lends a rich and deep flavor to the casserole.
- Beef broth | Beef broth combined with tangy cream cheese and Worcestershire makes delicious cheese sauce. Have you ever made beef broth?
- Cream cheese | It helps to set the cream cheese out before cooking, so it can come to room temperature.
- Cheese slices | Top the casserole with a few slices of provolone cheese. Shredded provolone or mozzarella cheese also works.
How to Make Low-Carb Philly Cheesesteak Casserole
Step 1 | Preheat the oven and cook the steak
Start by preheating the oven to 350°F (176° C). Next, set a large skillet over medium-high heat and add the butter until melted. Then, toss the shaved steak with salt, pepper, onion powder, and, if desired, a couple of splashes of Worcestershire sauce.
Saute the ingredients quickly, using tongs to toss just until the beef is lightly browned with some areas of pink still there– Don’t worry! It will finish cooking in the oven. Remove meat from the pan to a plate.
Step 2 | Cook the veggies
Add the diced yellow onions and red and green bell peppers, stirring until golden brown, soft, and translucent, taking about 7-10 minutes. During the last few minutes of cooking, stir in the sliced mushrooms. Add a tablespoon of oil or butter if the pan is too dry.
Step 3 | Combine the cheesy sauce ingredients
Add the minced garlic to the pan during the last couple of minutes and stir in Worcestershire sauce, cream cheese, and beef broth. Simmer the ingredients until they have thickened slightly, which may take around 5 minutes.
Step 4 | Mix the meat in and transfer to a dish
Next, return the shaved beef to the pan, stirring to coat it in the cheesy sauce. Then, remove the pan from the heat and transfer the ingredients to a 9×13-inch casserole or 2-quart baking dish. Finally, top the casserole with overlapping provolone slices overlapping, and it’s ready to slip into the oven!
Step 5 | Bake and serve!
And now for the best part. Bake this delicious dish for 15-20 minutes until the cheese melts and is bubbly.
Then, serve it as a tasty low-carb dinner with melty provolone cheese, or spoon the casserole onto toasted rolls. ENJOY!
Fresh Tips
- Have all the veggies and garlic diced and ready to add to the recipe. This will help things run smoothly as the process moves along quickly.
- Please don’t use stew meat as the steak in this recipe. It will be too tough in this dish.
- After cooking the meat, you can remove the excess grease by transferring it to a plate lined with paper towels.

Storage Tips
Make Ahead Philly Cheesesteak Casserole
This is a great recipe to make ahead of time. Cook and assemble the casserole, cover the dish with aluminum foil, and store it in the refrigerator. The next day, take the casserole out while the oven preheats! You may need to add a few more minutes to bake the chilled ingredients. It will last for up to five days in the fridge.
Refrigerate and Reheat Leftovers
If you have leftover Philly cheesesteak casserole, you can store the cooled leftovers in the refrigerator in an airtight container for up to five days.
- To reheat, preheat your oven to 350°F (176°C). Remove the plastic wrap or aluminum foil and cover the casserole with fresh aluminum foil.
- Bake the casserole for 20 to 25 minutes or until heated through.
How to Freeze Philly Cheesesteak Casserole
If you have leftovers you don’t plan to eat within five days, you can freeze them later. Let the casserole cool to room temperature before freezing. Place it in an airtight container or a heavy-duty freezer bag and freeze it for up to three months. To reheat, thaw the casserole overnight in the refrigerator and then follow the reheating instructions above.
Frequently Asked Questions
The classic Philly cheesesteak sandwich is usually made with ribeye steak, but other meats like flank and shaved steak work great too!

Why is it called Philly cheesesteak?
Philly cheesesteak sandwiches originated in Philadelphia in the 1930s. It was a sandwich made with thinly shaved steak and topped with melty cheese, a hoagie roll, hence, the name “cheesesteak.” It was initially referred to as a cheesesteak sandwich or the Philadelphia cheesesteak, but it didn’t take long for the modern name we know today to stick.
