How to Make Savory Low Carb Philly Cheesesteak Casserole
-
Preheat Oven: Begin by preheating your oven to 375°F (190°C). This will ensure that it’s nice and hot for your casserole, leading to a deliciously bubbly finish!
-
Slice Ingredients: Thinly slice your beef along with the green bell peppers and onion into thin strips. This preparation helps everything cook evenly, enhancing the flavors in your casserole.
-
Sauté Vegetables: Heat a large oven-safe skillet over medium-high heat and add a tablespoon of olive oil. Sauté the sliced onions and bell peppers for about 8-10 minutes until they soften and caramelize beautifully. Transfer them to a bowl and set aside.
-
Cook the Beef: In the same skillet, add another tablespoon of oil and slightly increase the heat. Add the thinly sliced beef in batches, cooking for 2-3 minutes each until browned. Season every batch with salt, pepper, garlic powder, and onion powder, then transfer to the bowl with the vegetables.
-
Deglaze Skillet: Pour about a quarter cup of beef broth into the skillet, deglazing it by scraping the bottom to incorporate those delicious browned bits. Turn off the heat and enjoy the aroma!

Make Cheese Sauce: In the same skillet, stir in the cream cheese and heavy cream over low heat until smooth. Add half of the provolone cheese, mixing until it melts and becomes creamy. Season the sauce with a pinch of salt and pepper for extra flavor.
-
Combine Ingredients: Add the cooked beef and sautéed vegetables back into the skillet, stirring until everything is evenly coated with the irresistible cheese sauce.
-
Prepare for Baking: Spread the mixture evenly in the skillet or transfer it to a 9×13 inch baking dish. Top it off with the remaining slices of provolone cheese, creating that melty, gooey layer everybody loves.
-
Bake Casserole: Bake in the preheated oven for 15-20 minutes, watching closely until it’s hot, bubbly, and the cheese is beautifully melted and lightly golden brown on top.

Chef's Helpful Tips
- When preparing the Savory Low Carb Philly Cheesesteak Casserole, ensure your beef is sliced thinly against the grain for maximum tenderness.
- Avoid overcrowding the skillet while cooking the beef to achieve a nice sear, which enhances flavor.
- For a creamier cheese sauce, allow the cream cheese to soften at room temperature before blending it with the heavy cream.
- Keep an eye on the baking time, as ovens can vary; you’re looking for the cheese to be melted and just starting to turn golden brown.
Savory Low Carb Philly Cheesesteak Casserole Recipe FAQs
How do I choose the best beef for my casserole?
When selecting beef, I recommend going for tender cuts like sirloin or ribeye for the Savory Low Carb Philly Cheesesteak Casserole. Look for cuts that are bright red with a bit of marbling; this fat adds flavor and makes for a juicier dish. Thinly slicing the beef against the grain will also ensure maximum tenderness.
How should I store leftover casserole?
To store leftovers, let the casserole cool completely, then place it in an airtight container. It can be kept in the refrigerator for up to 3 days. For best results, I suggest using glass containers, as they help maintain moisture and flavor.
Can I freeze the casserole, and how?
Absolutely! You can freeze the Savory Low Carb Philly Cheesesteak Casserole for up to 2 months. To do this, after it has cooled, wrap the casserole tightly in plastic wrap or aluminum foil. Then, place it in a freezer-safe bag. Make sure to label it with the date for easy tracking.
What’s the best way to reheat the casserole?
When you’re ready to enjoy your frozen casserole, thaw it overnight in the fridge. Preheat your oven to 350°F (175°C), then cover the casserole with foil and reheat for about 20-30 minutes until bubbly and heated through. For a delectable finish, remove the foil during the last 5-10 minutes to let the cheese get that lovely golden brown color.
Are there any allergies I should consider?
If anyone in your household has dairy allergies, I recommend substituting the cream cheese and heavy cream with a dairy-free cream cheese alternative and a plant-based cream. For gluten sensitivities, be sure to check the beef broth as some brands can contain gluten. Always read the labels to ensure that all ingredients meet your dietary needs.
What should I serve with the casserole?
This dish pairs wonderfully with a light salad or steamed vegetables like broccoli or asparagus. The freshness from the greens helps balance the richness of the casserole, creating a well-rounded meal experience. Enjoy!
