3. Add the minced garlic and thinly sliced beef ribeye to the skillet, breaking the meat up with a spoon. Cook until the beef is no longer pink and is lightly browned.
4. Stir in the softened cream cheese, sour cream, salt, black pepper, paprika, and dried oregano. Continue cooking and stirring until the cream cheese has melted and the mixture is smooth and creamy.
5. Remove the skillet from heat, then fold in half of the shredded provolone and all of the shredded mozzarella until evenly combined and gooey.
6. Transfer the mixture into a greased 9×13-inch baking dish, spreading it into an even layer. Top with the remaining provolone cheese for a golden, bubbly finish.

Frequently Asked Questions
Got a few questions swirling in your head? Here are answers to the most common queries about this casserole:
- How long does it take to prepare and cook this Cheesy Low Carb Philly Cheesesteak Casserole?
Total time is about 40 minutes. This includes 5 minutes to preheat your oven to 375°F, 5 minutes to cook the onion and bell pepper, 5–7 minutes to brown the beef and garlic, 3–4 minutes to stir in the cream cheese, sour cream, and seasonings until smooth, 10–15 minutes baking until bubbly, plus a 5-minute resting period before serving.
- Can I substitute any of the cheeses or dairy ingredients?
Yes. For a lighter cream cheese base, swap regular cream cheese with Neufchâtel. You can replace sour cream with full-fat Greek yogurt for a tangier flavor. If provolone or mozzarella isn’t on hand, shredded cheddar, Monterey Jack, or Swiss cheese work well; just adjust bake time slightly if you use a denser cheese. Keep the total cheese volume roughly the same to maintain creaminess.
- How should I store and reheat leftovers?
Transfer cooled casserole into an airtight container and refrigerate for up to three days. For single servings, microwave on medium power for 1–2 minutes until heated through. To reheat a larger portion, place in a 350°F oven for 10–12 minutes, covered with foil to prevent over-browning, then remove the foil for the last few minutes to restore cheesiness.
- How can I enhance the authentic Philly cheesesteak flavor?
Use thinly sliced ribeye or sirloin for the most authentic texture and flavor. You can also deglaze the skillet with a splash of beef broth or Worcestershire sauce before adding the cream cheese mixture. A pinch of onion powder or a few sliced mushrooms added with the peppers can deepen the savory profile.
- What are some ways to reduce the carbohydrate content even further?
Omit the bell pepper or onion entirely to cut carbs. You can add extra shredded beef or low-carb vegetables like zucchini ribbons or sliced mushrooms in their place. Choose full-fat dairy options, since they have fewer carbs than reduced-fat varieties, and be mindful of any sugar in your seasoning blends.
- Can I freeze this casserole for later?
Yes. You can freeze either before or after baking. To freeze unbaked, assemble in a freezer-safe dish, cover tightly with foil and plastic wrap, and freeze for up to two months. Thaw overnight in the refrigerator, then bake at 375°F for about 20–25 minutes until bubbly. For a baked version, cool completely, wrap tightly, and freeze. Reheat from frozen at 350°F for 25–30 minutes, then let rest before serving.
