The original Philly cheesesteak is a classic American regional dish developed in the early 20th century in Philadelphia. Made from thinly-sliced pieces of steak and Cheez Whiz on a long hoagie roll, the dish has die-hard fans.

This Philly cheesesteak casserole incorporates the well-loved flavors and ingredients of the sandwich and transforms it into an easy to prepare keto dish. Even without the bread, this low-carb meal is sure to satisfy.

This quick and easy keto casserole is made with seasoned ground beef instead of sliced beef for ease. It is then layered in a casserole dish with sautéed peppers and onions and topped with the all-important melty cheese.

While some loyal Philly cheesesteak fans love a smear of Cheez Whiz on their sandwich, this low-carb recipe is prepared without the processed ingredient. A bit of cream cheese is added to the meat mixture for that creamy mouthfeel and the casserole is topped with slices of provolone cheese. The whole casserole is baked until warm and perfectly melty but not browned and bubbly.

From the first bite, you won't miss the hoagie roll and you definitely won't miss the carbs. The whole meal is ready from start to finish in less than 45 minutes, so it is perfect to add to your weeknight dinner rotation.
