This easy keto philly cheesesteak casserole combines all the flavors of the classic comfort food without the carbs! It’s so delicious, you won’t even miss the bread roll.
What could be more delicious than shaved steak and sauteed veggies tossed in a creamy cheese sauce?
If that sounds great to you, then you have to try this casserole! The ingredient combination comes from a classic sub sandwich. However, by ditching the bread and turning it into a casserole, we eliminate most of the unnecessary carbs.
That means we get all the tasty flavors, but in a dish that’s completely low-carb.
If you’re looking for a hearty dinner you can throw together in about 10 minutes, give this philly cheesesteak casserole recipe a try.
This dish is very simple to make. We’ll cook the steak and veggies on the stove, melt the cheese sauce together, then mix all the ingredients in a baking dish and pop it in the oven!
- Cook the meat. Heat a skillet over medium high heat. Once hot, add olive oil and the shaved steak meat. Add steak seasoning, salt, and pepper to taste and saute until the meat is completely cooked through. Remove from the skillet and set aside.
- Sauté vegetables. Add the remaining olive oil to the skillet along with the onions and peppers. Season with salt and pepper to taste. Continue to cook until the veggies are just starting to become tender.
- Prepare cheese sauce. In a saucepan over medium heat, add the heavy whipping cream, cream cheese, and salt and pepper to taste. Continue to cook until the cream cheese melts and the sauce thickens. Add a shredded cheese into the sauce and stir to combine.
- Add main ingredients to casserole dish. Place the meat and veggies in a well greased 9×9 baking dish, then pour the cheese sauce on top.
- Prepare for baking. Toss the meat, veggies, and cheese sauce until well-combined. Sprinkle the remaining shredded cheese on top.
- Bake and cool slightly. Place the dish in the oven and bake at 350°F for 20 minutes, or until the cheese on top is slightly browned and bubbling. Remove from the oven and allow the cheesesteak casserole to cool for a few minutes.
If desired, you can top with freshly chopped parsley before serving. I like to divide the dish into 5 servings. At this size, there are 526 calories and 4 net carbs per slice.
Creating the Casserole
Philadelphians are very particular about what goes on a cheesesteak. The classic recipe is simply steak and cheese on a bread roll with optional onions.
By eliminating the bread to turn a sandwich into a casserole, I already made a major change to the traditional recipe. So I thought why not get a little creative.
I kept the classic onions but decided to add chopped bell peppers as well. They add great texture to this bake. I also chose to sprinkle some parsley on top for more flavor.
And finally, I wanted to make a cheese sauce instead of just melting cheese on top. A sauce means we can coat all of the ingredients in cheese, not just the top layer.
Philadelphians may be very rigid about their classic cheesesteak. But personally, I think there’s more than one way to make this delicious dish!
There are a few other ingredients you could add to the dish if you like.
Mushrooms and banana peppers are both considered traditional toppings. They’re also low in carbs to keep your philly cheesesteak casserole keto friendly.
Personally, I love this dish as a hearty casserole. However, you could modify the recipe to make a more classic sandwich instead.
To do this, prep all the ingredients on the stove like usual. Then, instead of adding them to a baking dish, layer the ingredients onto coconut flour bread, almond flour bread, or any other low carb bread or wrap!
