As a person that thoroughly enjoys bread, finding ways to enjoy some of my all time favorite sandwiches is a must.

Ever since we, as a family, decided to truly cut out 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.

What we then realized is that for the most part, bread is just a vessel, and doesn’t truly add to the flavor of a dish. Unless you’re eating special bread from an artisan bakery. When you’re talking regular-degular white bread from the grocery store – then nope. It adds nothing.

So, a great way of transforming a sandwich into a healthy meal, is by turning it into a salad, or a soup, or in this case – a super delicious casserole.

How To Make Easy Low Carb Keto Philly Cheese Steak Casserole:

I’ve got a new obsession – and it’s called “casserole”. Take everything you were going to put into a Philly cheese steak roll – 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

Start off by sauteing the onions, mushrooms and peppers together until soft. Scrape into a casserole dish.

Now, use the same pan and brown the ground beef.

Then, also scrape the ground beef into the casserole dish, with the peppers and onions. Mix everything well.

Now, mix the eggs and cream together and pour it over the beef and veggies.

Top with cheese and slide into your preheated oven for about 25 minutes at 200ºC/400ºF, until the cheese is bubbly and golden.

Then, when the cheese is melted, bubbly and starting to brown – remove from the oven. Cut the casserole into squares and serve up immediately. We like to serve this casserole with a dollop of our healthier homemade mayonnaise.

    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!:)
