Why we love this Philly Cheesesteak Casserole Recipe
Casseroles like this Philly Cheese Steak Casserole Recipe are always a good idea when you want to make a family dinner that's easy, but still really tasty and filling! We love this Philly Cheesesteak dinner because it's simple to make and will fulfill that "I want to order cheesesteak delivery" itch!
We originally thought that we'd serve this Philly Cheesesteak Casserole on top of a bed of egg noodles, and while it did taste great, we were looking for more of a filling, hearty meal. Isn't that the whole point of making a casserole?
We found the cheesesteak mix to be a little weak in terms of the amount for a casserole served on top of egg noodles. After giving it a little thought, we realized that this casserole dinner would be more like a casserole served on mashed potatoes. So the next day I scooped the left overs on a bed of mashed potatoes and THAT was what it needed, mashed potatoes! It's delicious. Such a great comfort food!

Walmart also has a Great Value Brand of seasoned Sirloin steak. Just note that I kept it frozen right up until I began making this easy casserole dinner recipe.
If you want to make the Philly Cheese Steak Strips from Scratch:
I didn't put any seasoning in the Cheese Steak Casserole mix (aside from Worcestershire) because the package said the beef was seasoned.
If I was going to add my own seasoning to plain sliced sirloin beef, I'd use: 1 teaspoon each of: onion powder, garlic powder, salt and ¼ teaspoon ground black pepper.
