Ever since we, as a family, decided to truly cut out all processed foods from our daily diet – when we DO eat bread, it’s scary what the results are – and for me, it’s usually a literal pain in the stomach.

A great way to transforming your favorite sandwich into a truly healthy and nutritious meal – is turning it into a salad, or a soup, or in this case – a super delicious Philly Cheesesteak Casserole.

How To Make Easy Low Carb Keto Philly Cheesesteak Casserole:

I’ve got a new obsession – and it’s called “casserole”. Take everything you were going to put into a Philly cheesesteak sandwich (or any other sandwich for that matter) – throw it into a casserole dish, pour egg over it, top with cheese and bake for 25 minutes.

It’s super easy and super delicious.

Here’s what you’ll need:

  • Ground Beef
  • Onion
  • Bell Peppers
  • Mushrooms
  • Egg
  • Cream
  • Cheese
  • Spices, Salt and Pepper

Step-By-Step Instructions:

  1. Start off by sauteing the onions, mushrooms and peppers together until soft. Scrape into a casserole dish and set aside.
  2. Now, use the same pan and brown the ground beef.
  3. Then, also scrape the ground beef into the casserole dish, with the peppers and onions.
  4. Mix everything well.
  5. Now, mix the eggs and cream together and pour it over the beef and veggies.
  6. Top with cheese and slide into your preheated oven for about 25 minutes at 200ºC/400ºF, until the cheese is bubbly and golden.
  7. Then, when the cheese is melted, bubbly and starting to brown – remove from the oven. Cut the casserole into about 8 squares and serve up immediately.
  8. We like to serve our Philly Cheesesteak Casserole with a dollop of our healthier homemade mayonnaise.

What Goes With Philly Cheesesteak Casserole?

The best way to serve this casserole is by offering a variety of toppings with it for everyone to pick and choose according to their own taste. Here’s what we like:

  1. Shredded Lettuce
  2. Chopped Tomato
  3. Banana Peppers
  4. Pickles

Do Philly Cheesesteaks Have Peppers?

Classic or traditional Philly Cheesesteaks do not have peppers or mushrooms – they are made with thinly sliced beef topped with melted cheese on a crusty bread roll.

Most sandwich shops offer fried onions, sweet peppers and fried mushrooms as toppings though.

In this Philly Cheesesteak Casserole Recipe, we have added these very common toppings as part of the casserole – to make a a proper, balanced meal.

    1. Hi Jessica, the casserole is cut into 6 largish squares, so one square per person. I would estimate that one square is 1 – 1.5 cups per person. Hope that helps!

  1. Hi, I made this earlier today and plan to reheat it for a late dinner tonight. I couldn’t resist tasting it and it is delish! My question is, there seems to be a lot of liquid in the bottom of the casserole. Is it supposed to be that way?

    1. Hi Michelle, we’ve never had the liquid issue – I’d say it should be slightly “saucy” at best. When I cook the veggies in a skillet, I tend to let them go until the water released from the mushrooms have cooked away. That’s the only place I can think of where extra liquid might come from. Not sure if that helps or not!

  2. Hey… this looks great!! Just one comment. I believe you left off the yellow bell pepper in the recipe? Just checking… I think it’s one green and one yellow, correct? looking forward to trying… as well as several of your recipes! Thank you!

    1. Hello Carol! Thank you for the feedback – I’ve fixed the recipe card to include 2 bell peppers. Let me know how it turns out for you if you try it!:)
