What to serve it with

Consider pairing this casserole with a fresh green salad or steamed vegetables for a well-rounded meal. You can also serve it alongside a dollop of sour cream or avocado for some added creaminess. If you want a bit more crunch, a side of pickles can complement the cheesesteak flavors beautifully.

How to store and freeze

Store any leftovers in an airtight container in the refrigerator for up to three days. For longer storage, freeze the casserole in a sealed container for up to three months. When reheating, make sure to heat to an internal temperature of 165°F to ensure safety. Certain food safety guidelines suggest not leaving food out at room temperature for more than two hours.

Tips for best results

  • Use lean ground beef to help keep the dish lower in fat.
  • Pre-sauté the vegetables for a few minutes before adding them to enhance their sweetness.
  • Consider using different types of cheese for unique flavors; mozzarella or gouda can also work well.
  • For added richness, mix in some cream cheese when blending in the seasonings.

Creative twists

  • Try adding mushrooms or spinach for extra vegetables and nutrients.
  • Incorporate spices like paprika or cayenne for a bit of heat.
  • Swap out the ground beef for ground turkey or chicken to lighten the dish.
  • Consider using pepper jack cheese for a spicy kick.
