What should I serve with this cheesesteak casserole recipe?

Since this is a heavier casserole, a side of roasted veggies goes great! Try some of my favorite veggie sides like Roasted Broccoli, Roasted Cauliflower, or a medley of Oven Roasted Vegetables. Of course, you could always stay true to Philly roots and serve with a side of fries dipped in malt vinegar. As an added bonus, this can be served as an appetizer with bread sticks or bagel chips to dip in it!

How To Make Cheesesteak Casserole

  • Preheat. Preheat your oven to 350°F. 
  • Cook the ground beef. Use an oven safe skillet or pot to cook the ground beef until browned, crumbling the pieces as you go. Drain out any excess fat. 
  • Season. Add the butter and stir until melted. Stir in the Worcestershire sauce, onion powder, garlic powder, salt, and pepper until combined. 
  • Add your veggies. Add the red and green bell peppers and sliced onions. Stir until they soften then add in the baby portobello mushrooms.and continue cooking for about 5 minutes. 
  • Pour the broth. Stir in the beef broth and bring it to a boil. Continue heating over high heat as you add in the pasta and cook for about 8 minutes. Of course you can check the pasta box to confirm the cook time of your preferred noodles.
  • Cut the heat. Remove the pot from heat. Stir in the chunks of cream cheese until they fully melt. Cover the entire top of the casserole with slices of provolone cheese. 
  • Bake. Bake the casserole for 20 minutes. You want the cheese to be golden on top and bubbling along the edges. 
  • Garnish. Top with freshly chopped parsley for a garnish, serve, and enjoy!

Ingredient Notes for This Casserole

  • Ground beef – Use a leaner ground beef to avoid a ton of grease from cooking. You can also swap the beef for thinly shaved ribeye for a traditional take on the cheesesteak. You can also use ground turkey if preferred. 
  • Seasoning – Feel free to add more garlic, onion, salt, and pepper according to your taste. Or lessen the amounts if desired. You can also add freshly minced garlic for added garlicky flavor! 
  • Half and half – To thin the cheese a bit and help it melt, add a dash of half and half or heavy cream to the mixture. 
  • Beef broth – You can use vegetable broth or stock if that’s already on hand. You may want to add a bit more salt if going this route.

    This was absolutely delicious. Made it exactly as written. Used a 5 qt. braiser and it fit perfectly. Was pretty soupy when I put the provolone on top and I was a little nervous but it definitely was not soupy after 20 min baking in the oven. Will absolutely make this again. A definite winner.
