Low Carb Philly Cheesesteak Ingredients
• Here’s everything you need to create this deliciously satisfying dish!
For the Casserole
- Ground Beef – 2 lbs, 80/20 fat ratio preferred for a juicy protein base.
- Onion – 1 large, diced to add sweetness and depth to the flavor.
- Bell Peppers – 2 large, diced (green, red, or mixed) for color and crunch.
- Garlic – 2 cloves, minced; it’s the aromatic star that enhances overall flavor!
- Cream Cheese – 8 oz, softened; provides creaminess and a delightful tang.
- Worcestershire Sauce – 2 tbsp; deepens the umami flavor, essential for the cheesesteak vibe.
- Salt and Pepper – A must for seasoning and enhancing the taste of your casserole.
For the Cheesy Topping
- Provolone Cheese – 8 oz, sliced; it melts beautifully, offering that classic cheesesteak taste.
- Mozzarella Cheese – 1.5 cups, shredded; adds a stretchy, melty texture that everyone loves.
For Cooking
- Olive Oil – 1 tbsp; perfect for sautéing the vegetables until they’re just right.
Step‑by‑Step Instructions for Low Carb Philly Cheesesteak Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven is heating, grab a 9×13 baking dish and spray it generously with non-stick spray to prevent sticking. This Low Carb Philly Cheesesteak Casserole will need that space to bubble up and become golden perfection as it bakes.
Step 2: Sauté the Veggies
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Once the oil is shimmering, add the diced onions and bell peppers to the skillet. Sauté for about 5–6 minutes, stirring occasionally, until the veggies soften and become fragrant. They should be tender and vibrant, ready to meld with the beef.
Step 3: Add Garlic
Stir in the minced garlic and continue to cook for another 30 seconds. You’ll start to smell the savory aroma fill your kitchen, signaling that it’s time to move on to the next ingredient. Make sure to stir frequently to avoid burning the garlic; you want it to be aromatic but not browned.
Step 4: Cook the Beef
Add the seasoned ground beef to the skillet, breaking it apart with a spatula. Season with salt and pepper, allowing it to cook for about 7–8 minutes until it’s browned and no pink remains. Stir occasionally, draining any excess fat to keep the casserole lean and delicious.
Step 5: Mix in Creaminess
Once the beef is fully cooked, stir in the Worcestershire sauce and 8 ounces of softened cream cheese. Keep stirring until the cream cheese has melted completely, creating a creamy mixture that envelops the beef and veggies. This richness will add the signature comfort to your Low Carb Philly Cheesesteak.
Step 6: Assemble the Casserole
Spread the beef mixture evenly into your prepared baking dish. Take 8 ounces of sliced provolone cheese and tear it into pieces, layering it over the beef mixture. This step will ensure a gooey, cheesy goodness when baked. On top of that, sprinkle 1.5 cups of shredded mozzarella cheese for an over-the-top, melty finish.
Step 7: Bake to Perfection
Transfer the baking dish to your preheated oven and bake for 22–25 minutes. Keep an eye on it towards the end; the cheese should be melted and lightly golden, bubbling invitingly. The aroma will be irresistible as it bakes, making your kitchen feel warm and welcoming.
Step 8: Let Rest and Serve
Once it’s out of the oven, allow the casserole to rest for about 5 minutes before serving. This resting time lets the flavors settle and makes serving easier. Scoop generous portions onto plates and enjoy your comforting, savory Low Carb Philly Cheesesteak Casserole with family or friends!

Expert Tips for Low Carb Philly Cheesesteak
- Choose the Right Beef: Use 80/20 ground beef for optimal flavor and juiciness. Leaner cuts can result in a dry casserole that lacks that classic cheesesteak richness.
- Perfectly Sautéed Veggies: Don’t rush the sautéing process! Allow onions and bell peppers to soften completely for enhanced sweetness and depth—this is key for your Low Carb Philly Cheesesteak casserole.
- Cream Cheese Integration: Make sure your cream cheese is softened before mixing; it blends better and creates that luscious texture that’s vital for a creamy casserole.
- Layer Cheese Wisely: Tear the provolone into pieces for even melting. Stacking too many cheese slices can lead to uneven results, which takes away from that gooey deliciousness!
- Rest Before Serving: Let the casserole rest for a few minutes after baking. This helps the flavors meld together and keeps the casserole from falling apart on your plate.

Low Carb Philly Cheesesteak Casserole Recipe FAQs
How do I choose the best ground beef for this casserole?
Choose ground beef with a fat ratio of 80/20 for the best flavor and juiciness. Higher fat content enhances the overall richness, making it reminiscent of a classic cheesesteak. A leaner cut may lead to a dry casserole, so stick to the preferred ratio for optimal results!

When you’re ready to enjoy it, thaw in the fridge overnight and reheat in the oven at 350°F (175°C) until hot and bubbly.
What should I do if my casserole comes out too dry?
If your casserole is on the dry side, it may be due to overcooking the beef or not using enough cream cheese. To avoid this, make sure to monitor your cooking times closely. Adding an additional splash of Worcestershire sauce or a dollop of cream cheese can bring back moisture and enhance the richness.
Is this casserole safe for people with dairy allergies?
Unfortunately, this Low Carb Philly Cheesesteak Casserole contains cream cheese and provolone cheese, which are dairy products. For a dairy-free alternative, consider using dairy-free cream cheese and nutritional yeast in place of the cheeses. Just keep in mind that flavor and texture may differ slightly.
Can I customize the vegetables in this casserole?
Very! Feel free to mix in additional veggies like mushrooms, spinach, or zucchini for more variety and nutrition. Cooking the vegetables until softened is key to ensuring they blend nicely with the beef and cheese in the casserole, enhancing its overall flavor!
