Recipe variations

Keto Philly Cheesesteak Casserole With Ground Beef

This is a great alternative to the steak! Especially if you ask for half beef, half pork… Delicious! The instructions are the same, but you have to separate and move the meat, so it gets brown and yummy.

It will not take long! If you want it extra crispy, add some olive oil and cook it until it gets golden… So tasty!

Philly Cheesesteak casserole with Pillsbury biscuits and Velveeta (NON KETO!)

We are going to get into details here: First, you will need the meat of your preference, some olive oil, minced onions, sliced green peppers, Velveeta cheese, provolone or mozzarella, one cup of milk, and a can of Pillsbury biscuits.


  1. Preheat the oven to 350 degrees.
  2. Brown the meat you are using in a skillet and put it apart.

Keto Philly Cheesesteak casserole with noodles

Actually, the recipe is the same with any kind of pasta, but noodles add to any dish this amazing touch we love. If you’d like to keep it Keto, then replace the noodles with our Zoodles (zucchini noodles!). 

What will we need, then?: Basically, you need the same ingredients as with the Keto Philly cheesesteak casserole from earlier, but adding the noodles and water.

What will we do? You will cook the noodles al dente, following the previous instructions, and add the noodles (or any pasta) with the sauce when it is done. Easy!

Keto Philly Cheesesteak casserole salad

Yes, we are not joking. Why not mix a delicious cheesesteak casserole with all the fiber and vitamins of a salad?

A nice and healthy way to eat all the nutrients in one meal! And best of all? It is completely low-carb! Do you want to know how to do it?

First of all, here is what you will need: meat, veggies, oil, seasoning, milk, cheese, cream, lettuce, spinach, lime, and peanuts. Let’s do it!


  1. Let’s start with the salad. All you have to do is to use a large bowl to mix the lettuce and spinach leaves and add some salt, olive oil, and lime.
  2. Keep it there until the rest of the meal is done.
  3. Preheat the oven to 350 degrees.
  4. Cook the meat, put it in a bowl, and cook the veggies until they are tender.
  5. Add them to the same bowl, and use the same skillet to get the perfect sauce: add the cream, the cheese, the milk, and mix it until they are melted.
  6. Add the meat and veggies, and mix it all together.
  7. Time to put it all together! In the salad bowl, put the cheesesteak and mix it until you feel like it is all combined.
  8. Do you feel like something is missing? Of course! The cheese! In a non-stick pan, add the provolone and mozzarella and cover it with a lid (use low heat).
  9. Once it is all melted, you just have to top your dish with it, and add some peanuts on the top.
  10. You are so welcome!

Low Carb Keto Philly Cheese Steak



Step 1

Let's get into it! Preheat your oven to 350 degrees.

Step 2

Set your skillet to heat at medium-high, and when it is hot, add the sliced steak. Be careful not to get burnt! Season it with salt, pepper, and steak seasoning, and cook it for about 3 minutes, making sure you are cooking both sides of the steak.

Step 3

Add the peppers, mushrooms, onions, and garlic to the skillet. When the vegetables are tender and the steak is no longer pink, you are ready to go.

Step 4

A piece of advice over here! If you see some water or fat excess, drain it. We do not want a soapy residue!

Step 5

Lower the heat to low-medium, and add the Worcestershire sauce and the cream cheese. Cook until the cream cheese is melted.

Step 6

Time to remove the skillet from the heat!

Step 7

In a bowl, mix the eggs, the Parmesan cheese, and the whipping cream.

Step 8

Oven time! Take a casserole and spray it with some oil or cooking spray. Now we put the skillet's content into the casserole, and top it with the mixture from the bowl.

Step 9

Add the provolone slices on top, and bake for about 20 minutes, until the cheese looks crispy and delicious. Yummy!

Step 10

Take it out, let it cool for a few minutes (we do not want you to get burnt), and enjoy your tasty low-carb meal!


Tips: We are going to give you a few tips, so you can make this dish your own, and have it the way you love it the most: • Even if the steak is the perfect meat for this recipe, you can also use chicken if you feel like it. It will be delicious no matter what! • You can use cheddar, which is the bright orange cheese used in Philly sandwiches instead of Parmesan if you like it better, but the Parmesan has fewer calories and a stronger flavor. It will depend on your taste! • You can keep it for the rest of the week, so you do not have to cook for a while. You can even freeze it! It will be as delicious as the first day!
