This easy dinner idea comes with everything love about the classic sandwich, in casserole form, topped with crispy tater tots — YUM!

What’s in this Philly Cheesesteak Casserole?

You don’t need a long list of ingredients to make this tasty meal. In fact, you just need just 5 ingredients, 6 if you want to include mushrooms:

• Ground beef (or use shaved steak)
• Green bell pepper
• Onion
• Mushroom – optional but highly recommend!
• Provolone cheese
• Tater tots

That’s it, other than some salt and pepper to season things. Yes, it’s as easy at it sounds to prep.

How to Make this Cheesesteak Casserole

You can cook the beef, peppers, onion and mushrooms all together in a large skillet to save time. Then layer those ingredients into an 8×8 baking dish, and top with provolone cheese and tater tots. Bake in the oven until tots are nice and crispy, about 30 minutes.

Lower the Fat

Here’s a little tip for lowering the fat in this dish: drain your ground beef  after cooking. Also, choose a lean blend of beef or steak to start with. If you find this leaves your dish lacking flavor, add in a few dashes of Worcestershire sauce to your lean meat.

Extra Seasoning for Your Meat

I love steak and ground beef with just salt and pepper but if you’re craving something a little more here are some ideas to spice things up. Trying adding garlic or onion powder to your ground beef (or steak) when you cook it. Or you can opt to use pre-seasoned and pre-cooked shaved steak. You can actually find this at most grocery stores.

Some herbs that go well to enhance to flavor of Philly cheesesteak beef are: paprika, chili powder, thyme, marjoram and basil. Any or all of these would be great additions to your meat; adding them in as you cook or heat your meat.

I made this for supper 12/19/2021. I added Garlic, onion powder, and Worcestershire sauce and Lowry's season salt. It was easy to get put together and put it in the oven. I enjoyed it. Next time I'm going to put mushrooms in it. I'm glad I could use the ingredients I had on hand. My husband liked the casserole too! I will be making this again.
