Ingredients for Philly Cheesesteak Casserole.

What is a Philly Cheesesteak Casserole?

This casserole has all the same components of traditional Philly cheesesteak sandwiches, minus the bread. We also used ground beef instead of thinly sliced ribeye and cook it down with bright green red bell peppers and onions. To finish it off, the skillet is topped with provolone cheese slices and baked until bubbly in the oven.

Making this Philly Cheesesteak Casserole Recipe

To prepare this simple casserole all you need is an oven-safe skillet or baking dish and a handful ingredients. We recommend using a cast-iron if you have one (we love this one from Lodge).

  • Prepare the Ground Beef: In a skillet preheated over medium heat, brown the ground beef and season it with salt and pepper.
  • Add in the Veggies: Add in the diced onions and peppers and sauté the ground beef mixture until the veggies soften.
  • Stir in the Cream Cheese: Stir in the cream cheese and remove the skillet from heat.
  • Top with Provolone: Cover the top of the casserole with slices of provolone cheese.
  • Bake the Casserole: Bake the casserole in the oven at 350°F for about 15 minutes or until the top is golden and melty. Dig in and enjoy!

Hot Tip: Opt for grass-fed, high-quality ground beef. The meat is what brings most of the flavor front and center in this dish, so treat yourself to the good stuff. Costco has some really affordable grass-fed ground beef if you need a good suggestion!

5 Tips for Nailing this Philly Cheesesteak Casserole

This simple casserole couldn’t be any easier to throw together, but these 5 foolproof pointers will help you nail it.

  • Opt for lean ground beef. To prevent your casserole from turning out too greasy, opt for lean ground beef. The sweet spot is 85% lean or leaner. If a good amount of grease still pools at the bottom of the skillet, drain it before you add the veggies and cream cheese.
  • Slice the veggies into equal-sized pieces. To promote even-cooking, slice the veggies into equal-sized pieces before adding them into the skillet. Make this a no-brainer by using a veggie slicer if you have one.
  • Add extra cheese. Make the casserole extra cheesy by adding in cheddar cheese or provolone cheese directly into the meat mixture – not just on top.
  • Add in some mushrooms. If you want to double up on your serving of veggies, add in some sautéed mushrooms to the meat mixture as well.
  • Swap in a different kind of ground meat. If you want the dish to be a bit lighter, swap in ground turkey or ground chicken instead.
