Tips and Tricks
- If you want softer vegetables that are lightly blackened, feel free to cook them longer before putting the casserole together.
- Ground beef may be used instead of steak.
Variations
- Add ¾ cup sliced sautéed mushrooms.
- If you like, poblano peppers are also great here.
- Cheddar cheese will also work here.
How to Make Keto Philly Cheesesteak Casserole
First, preheat your oven. While the oven is preheating, heat the oil in a large skillet over medium-high heat. Add the steak and cook until browned. Remove from the heat and chop.
Add the onions and peppers to the skillet and cook for 6 minutes, until softened. Add the garlic powder and season to taste with salt and pepper. Toss the vegetables with the steak and remove from heat.
While the steak and vegetables are cooking, melt the butter in a saucepan and add the broth. Bring to a simmer over medium-high heat. Reduce the heat to medium and add the cream cheese. Whisk to incorporate as the cheese melts.
Once the cream cheese is melted, reduce the heat to low and add half of the provolone cheese. Cook until the cheese is melted and the sauce has thickened.
Add the cheese to the steak mixture and stir to combine. Transfer to a 9 x 9 casserole dish and top with the remaining cheese.
Bake for 30 minutes, until bubbly.

Delicious, easy to make, husband loved it...and plenty for a few meals, next time I will make half the amount...i was craving for a grinder...this was very satisfying to say the least. I made alot of your recipes, but I love the rueben sandwich with the Chaffle the best. Keep them coming

Robyn says
So delicious! Non-keto family put on small buns.
Everyone loved it!
Wendy Polisi says
So glad you liked it! With three kids I strive to create recipes that work for me and the rest of the family. My kids do the same thing with this recipe.
Kim says
Is there a certain steak to use? The recipe says shaved steak (Im assuming similar to steak and cheese) but the first picture looks like steak sliced up,
Was hoping to try this today but not sure the right meat
Wendy Polisi says
You can use what you want. I order my meat from a local butcher and they offer thin sliced strip steaks, so that is what I used. If that isn't available, you can use any steak and cut it thin.
Hanna says
The ingredient list says 4 oz. of cream cheese. Then in the instructions, 8 oz. are mentioned. Which is it? Very confusing!
Wendy Polisi says
It is 4 oz of cream cheese and 8 ounces of the provolone that goes into the sauce. You save the remaining provolone for topping.
Margaret M Mundy says
Made tonight. All the family loved it!!!
Moonkitty says
Just made this the other night. Halved the recipe and added the mushrooms. It was wonderful! Just like a cheesesteak without the roll. Hubs loved it also and raved about how good it was and he is a cheesesteak aficionado. This will definitely be in our rotation.
Wendy Polisi says
So glad that you both enjoyed it! Thanks for taking the time to let me know.
Eileen says

Cindy Shrout says
I made this today 12/31/25 with sirloin steak into strips, it was fabulous! I kept it keto, no bread of any kind. I wish I could upload a photo, so you could feast your eyes!
