How to Make Low Carb Philly Cheesesteak Casserole
-
Prepare the veggies by thinly slicing the green bell pepper and onion. If you’re adding mushrooms for extra flavor, slice those as well. This will help your casserole achieve a delightful mix of textures!
-
Sauté the onions and bell peppers in a large skillet or Dutch oven over medium-high heat with a tablespoon of cooking oil for about 8-10 minutes. You want them tender and slightly caramelized. Once done, transfer them to a large mixing bowl and set aside.
-
Cook the shaved beef steak in the same skillet, adding more oil if necessary. Working in batches, season with salt, black pepper, garlic powder, and onion powder. Sear until browned and cooked through, about 2-3 minutes per batch. Transfer the cooked beef to the mixing bowl.
-
Mix the softened cream cheese and half a cup of beef broth into the bowl with the cooked beef and veggies. Stir it all thoroughly until you’ve created a creamy, delicious filling.
-
Preheat your oven to 375°F (190°C) while you prepare the baking dish. Lightly grease a 9×13-inch dish to prevent sticking—this will make serving much easier!
-
Spread half of the creamy beef and vegetable mixture evenly over the bottom of the baking dish. This will create the perfect base for your casserole.
-
Layer half of the provolone cheese slices over the steak mixture, which will melt beautifully and give that classic cheesesteak vibe.
-
Top with the remaining steak and veggie mixture, making sure it’s spread out evenly across the dish. This helps everything cook evenly and meld together nicely.
-
Arrange the remaining provolone slices over the top, covering the casserole completely with that glorious cheesiness!
-
Bake in the preheated oven for 20-25 minutes. You’ll know it’s ready when it’s bubbly around the edges and the cheese on top is melted and lightly golden.
-
Rest the casserole for about 5-10 minutes before serving. This lets the flavors settle a bit and makes it easier to cut and serve.
Optional: Garnish with fresh parsley for a pop of color!

Low Carb Philly Cheesesteak Casserole Recipe FAQs
How do I select ripe ingredients for my casserole?
When choosing bell peppers and onions, look for firm, glossy skin without any dark spots or wrinkles. The bell peppers should feel heavy for their size, indicating ripeness and freshness. If possible, opt for organic varieties to avoid pesticides, especially if you’re serving kids or pets.
What is the best way to store leftovers?
Absolutely! Store any leftover Low Carb Philly Cheesesteak Casserole in an airtight container in the fridge. It will stay fresh for up to 3 days. When you’re ready to enjoy it again, simply reheat it in the oven or the microwave. Make sure to cover it to keep it from drying out!
Can I freeze the casserole for later use?
Very! To freeze your Low Carb Philly Cheesesteak Casserole, first let it cool completely. Then, transfer it to a freezer-safe container or wrap it tightly using heavy-duty aluminum foil. It will keep well for up to 3 months. When you’re ready to eat, thaw it overnight in the fridge and reheat at 350°F (175°C) for about 20-25 minutes.
What are some common troubleshooting tips for this recipe?
If your casserole seems a bit runny, it’s often because there was too much liquid added from the beef or broth. For a thicker consistency, consider reducing the beef broth next time or using less cream cheese. Conversely, if it feels too dense, adding a splash of extra beef broth or a bit of cream during the mixing stage can help lighten it up.
Can I make this dish gluten-free or dairy-free?
Yes, indeed! To make a gluten-free version, ensure that your Worcestershire sauce is gluten-free, or substitute it with coconut aminos. For a dairy-free option, you can use cashew cream or a dairy-free cream cheese alternative instead of regular cream cheese and provolone. Feel free to experiment with various alternatives that suit your dietary needs!
