How to Make Keto Philly Cheesesteak Casserole (Step-by-Step)

Making this casserole is straightforward, and cleanup is a breeze. Here’s how to do it:

1. Preheat your oven to 375°F and prepare a baking dish by greasing it lightly with butter or oil.
2. Sauté the vegetables. In a skillet over medium heat, cook the onions, bell peppers, and mushrooms until soft and fragrant.
3. Add the beef. Stir in your sliced or ground beef and cook until browned and cooked through.
4. Incorporate the cream cheese. Reduce heat and stir in cream cheese until fully melted and evenly distributed.
5. Transfer to a casserole dish. Spoon the mixture into the baking dish and spread it evenly.
6. Top with shredded cheese. Sprinkle provolone or mozzarella across the surface.
7. Bake uncovered for 15–20 minutes or until the top is bubbling and lightly golden.
8. Chill for 10 minutes to set the layers before serving. This helps firm up the casserole and makes slicing easier.

Pro Tips for the Best Keto Cheesesteak Bake

Even simple recipes can shine with the right techniques. Here’s how to elevate your casserole:

• Use ribeye for the most authentic Philly flavor, but don’t shy away from ground beef if you need a shortcut.
• Sauté the vegetables separately to prevent them from overcooking and getting soggy.
• Add a splash of Worcestershire sauce or beef broth for a deeper, more savory flavor.
• Customize your cheese. While provolone is classic, cheddar adds sharpness, and Swiss adds creaminess.
• Finish under the broiler for a few minutes if you want a more golden, bubbly cheese top.
