What is a Philly Cheesesteak?

A traditional Philly Cheesesteak sandwich is a classic. It has lots of thinly shaved steak and a good amount of cheese. We’ve often had the cheesesteak sandwiches with sauteed onions and peppers. Serve it up on a hoagie roll and you’ve got yourself a sandwich!

No Bread in This Casserole

Typically, Philly Cheesesteak is a delicious beefy and cheesy sandwich. However, this twist on the sandwich is a casserole without the bread. I urge you to give this a try. It is over-the-top amazing.

Believe me, this recipe is a keeper.

Cooking with My Daughter-Making Up Recipes

This week, my daughter and I have been cooking together quite a bit. I just love those days. Well, we were pondering what to make for dinner. After a trip to the freezer, we landed on this Philly cheesesteak casserole. However, when we researched recipes we were not excited about what we found. Therefore, we made up our own. Believe me, it turned out so delicious, we will be making this again and soon too.

Thin Sliced Beef or Ground Beef for This Recipe

I used very thinly sliced beef for this recipe today because I had it in the freezer. (I thawed it most of the way before using it). However, if I did not, I would go ahead and use ground beef.

Notice how thin the beef is sliced in the photo? This will make sure that when this casserole bakes, it will have a delicious tender meat too. Meat Option: if you do not have thin beef, go ahead and use ground beef. If you are using that, just cook ahead of time. That way, the beef will be in small pieces. You could also use chicken for this recipe I think too.

So, What About Tacos?

Try a new Twist on a Taco and Philly Cheesesteak.

I happened to have some flour tortillas at home and thought this might be a good combination. It was! If you are a person that would miss the bun with this Philly cheesesteak, then try and fried flour shell.

Frying the Flour Shells

I put a little oil in a skillet and fry the shell for about 30 seconds on each side. Then using two forks, I fold the shell in half and fry for about 30 seconds on both sides again. Remove and drain on a paper towel. Why fry and flour shell? Our family thinks that it brings out the sweetness in the flour and takes the raw flour taste away. Plus there is a little crispiness to the shell now.

Make this Casserole in Advance

Make up the Philly Cheesesteak Casserole up to the point of baking. Then cover it over and refrigerate it until about 30 minutes before you want to bake it. Follow the recipe for baking until hot and bubbly.

Freeze This Casserole

Make up the casserole up to the point of baking.Wrap it well with plastic wrap, then wrap again in aluminum foil. Freeze for up to 2 months. When you are ready to make this, let the casserole sit out 30-60 minutes before baking to come closer to room temperature. Bake as the recipe states, but it may take a little bit longer depending on how cold the casserole is. Make sure it is heated through the middle and bubbly around the edges.
