    Want all the flavors of your favorite sandwich in the confines of an easy to make dish? You are going to fall in love with this Keto Philly Cheesesteak Casserole. The creaminess of the cheese sauce plays perfectly with shaved steak and sautéed onions and peppers. This has quickly become one of my favorite meals.

    Since going low-carb, one of my favorite things is taking my favorite flavor profiles and turning them into delicious, cheesy casseroles.

    You can see that here with this Keto Reuben Casserole, with this BBQ Chicken Casserole, and this Keto Chicken Parmesan Casserole.

    My latest casserole obsession is this Keto Philly Cheesesteak Casserole.

    It is easy to make and always a hit at my house - I think you will agree that this one is a keeper.

    Can I Use Ground Beef Instead of Steak?

    For superior texture, I recommend reheating this recipe in the oven. If you prefer, you may also reheat it in the microwave.


    Can This Recipe Be Made Ahead?

    You can make this up to one day ahead and cook it just before serving. Leftovers will keep for three or four days in a sealed container in the refrigerator.

    Reheating

    For superior texture, I recommend reheating this recipe in the oven. If you prefer, you may also reheat it in the microwave.

    Freezing

    It can be frozen for about three months, but note that there will be a slight decline in the overall texture.

    Tips and Tricks

    • If you want softer vegetables that are lightly blackened, feel free to cook them longer before putting the casserole together.

    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.

      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

        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.

      The ingredient list says 4 oz. of cream cheese. Then in the instructions, 8 oz. are mentioned. Which is it? Very confusing!

        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.

      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.
