This cheesy Philly cheesesteak casserole is perfect for a low-carb meal or a speedy filling for brioche buns. It’s crazy easy, savory, and 100% kid-friendly!

Baked Philly Cheesesteak Casserole.

Before Momsdish became my full time job, I used to work in corporate Seattle. What a career shift, right? On the days that I wasn’t able to bring a homemade meal for lunch, I often went out for lunch in the city. One of my favorite lunches was a Philly cheesesteak sandwich, which is where this recipe gets its inspiration.

I love Philly cheesesteak sandwiches, but I also love casseroles. If you’re also a fan of foolproof, no-hassle casserole recipes like my tater tot casserole, this gooey, beefy Philly cheesesteak casserole has your name all over it. Whip it up to stay true to your keto or gluten-free diet, or make a pan for quick, sloppy joes-style Philly cheesesteaks sandwiched between fluffy brioche buns.

What’s in this casserole? This casserole has all the same components of traditional Philly cheesesteak sandwiches, minus the bread. It has ground beef, bell peppers, and onions. To finish it off, the skillet is topped with provolone cheese slices and baked until bubbly in the oven.

Ingredients for Philly Cheesesteak Casserole.

Making this Philly Cheesesteak Casserole Recipe

To prepare this simple ground beef Philly cheesesteak casserole, all you need is an oven-safe skillet or casserole dish and a handful of simple ingredients. I recommend using a cast-iron dish like this one so you can use the same pan to sauté and bake!

  • Prepare the ground beef: In a skillet preheated over medium heat, brown the ground beef and season it with salt and black pepper.
  • Add in the veggies: Add in the diced onions, red peppers, and green bell peppers, then 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. Garnish with parsley, dig in, and enjoy!

Make ahead tip: Feel free to prep this casserole 2-3 days in advance by assembling it all the way up until the baking step. Store it in the fridge covered and pop it in the oven to finish it off for a quick busy night meal.

A Few Tips to Nail this Casserole

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

  • Buy quality lean ground beef: Instead of the traditional steak, opt for grass-fed, high-quality lean ground beef. The meat brings most of the flavor front and center in this dish, so treat yourself to the good stuff. To prevent your casserole from turning out too greasy, opt for lean ground beef (85% lean or leaner).
  • Drain the excess grease: If a good amount of grease 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 chopper.
  • Add extra cheese (optional): Make the casserole extra cheesy by adding in cheddar cheese or provolone cheese directly into the meat mixture – not just on top.
  • Season it up: If you feel like the beef mixture needs more flavor, try adding in a shake or two of worcestershire sauce. Minced garlic (or garlic powder) and Italian seasoning are also reader’s favorites.
  • Throw in some mushrooms (optional): If you want to double up on your serving of veggies, add sautéed mushrooms to the meat mixture.
  • Swap in a different kind of ground meat (optional): If you want the dish to be a bit lighter, swap in ground turkey or ground chicken instead of beef.

Serving tip: Serve the Philly cheesesteak casserole as-is, as a sandwich between buns or French bread, or nacho-style with air fryer tortilla chips.

Storing & Reheating Cheesesteak Casserole

I looove Philly cheesesteak leftovers! As the casserole sits, it actually continues to develop its flavor and make for some really tasty leftovers. Try it out for yourself!

  • Refrigerator: Keep the casserole fresh for up to a week in an airtight container in the fridge.
  • Freezer: Store cooked and cooled leftovers in an airtight container for up to three months in the freezer. Thaw overnight in the fridge.
  • Reheating: Reheat the casserole in the oven (for large portions) or microwave (small portions).
