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. We like to add shredded lettuce, chopped tomatoes, banana peppers, and 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 proper, balanced meal.

Can you use steak instead of ground beef?

Why not! Try using a thinly sliced steak, just like a more traditional cheese steak sandwich. Just season and cook the steak separately first before combing the ingredients into the dish.

Can you make Philly Cheesesteak Casserole ahead of time?

Casseroles are always a great option for food prep. You can prepare the main components and store them separately, or assemble the whole casserole and keep refrigerated until you are ready to cook.

    This is delicious! Easy recipe for this inept cook. My husband loved it and told me to make more servings next time. He is a picky eater, too.

    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!

  2. 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!

  3. 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!:)
