Step‑by‑Step Instructions for Low Carb Philly Cheesesteak Casserole
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C) and grab a 9×13 baking dish. Lightly spray it with non-stick cooking spray to ensure your Low Carb Philly Cheesesteak Casserole releases effortlessly after baking. This initial prep will set the stage for a perfectly baked dish that’s easy to serve.
Step 2: Sauté the Vegetables
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the diced onion and bell peppers, sautéing them for about 5-6 minutes until they soften and become fragrant. Stir in 2 cloves of minced garlic and continue to sauté for an additional 30 seconds, ensuring the garlic doesn’t burn, which would alter the flavor.
Step 3: Cook the Beef
Next, break the ground beef into the skillet, seasoning it with salt and pepper to taste. Cook for 7-8 minutes, using a wooden spoon to crumble the beef as it browns. Keep cooking until no pink remains, draining any excess fat from the skillet to achieve a less greasy casserole.
Step 4: Combine and Melt
Stir in 2 tablespoons of Worcestershire sauce and 8 ounces of softened cream cheese to the cooked beef mixture. Mix thoroughly until the cream cheese melts and blends seamlessly into the meat, creating a creamy, flavorful foundation for your Low Carb Philly Cheesesteak Casserole.
Step 5: Assemble the Casserole
Transfer the savory beef mixture into your prepared baking dish, spreading it evenly across the bottom. Next, layer with 8 ounces of torn provolone cheese, followed by 1.5 cups of shredded mozzarella cheese, ensuring an even coverage for a bubbly, cheesy top during baking.
Step 6: Bake to Perfection
Pop the casserole into your preheated oven and bake for 22-25 minutes. Keep an eye on it, and remove it once the cheese is melted and bubbly, showcasing a golden hue on top. This is when your kitchen will be filled with irresistible aromas!
Step 7: Rest and Serve
Once baked, take your Low Carb Philly Cheesesteak Casserole out of the oven and let it rest for about 5 minutes. This resting time allows the flavors to settle, making it easier to serve. Grab your spatula and dish up generous servings to enjoy this hearty delight!

Make Ahead Options
These Low Carb Philly Cheesesteak Casserole preparations are perfect for meal prep enthusiasts looking to save time during hectic weeknights! You can sauté the vegetables and cook the ground beef up to 24 hours in advance; simply store them in an airtight container in the refrigerator.

When you’re ready to serve, simply bake the casserole at 350°F (175°C) for 25-30 minutes until heated through and the cheese is bubbly. Enjoy your delicious, stress-free meal with minimal effort!

Low Carb Philly Cheesesteak Casserole Recipe FAQs
How do I choose the right bell peppers for this casserole?
For the best flavor and visual appeal, select bell peppers that are firm with vibrant colors. Look for peppers that are shiny and have no dark spots or blemishes. Using a mix of colors—like red, green, and yellow—adds an extra layer of sweetness and aesthetic charm to your Low Carb Philly Cheesesteak Casserole.
How should I store leftovers?
Absolutely! Store your Low Carb Philly Cheesesteak Casserole in an airtight container in the refrigerator for up to 4 days. If your family typically enjoys second helpings, I recommend portioning leftovers for easy reheating. Don’t forget to let it cool completely before sealing to maintain its deliciousness!

Yes! I often freeze this casserole for a quick future meal. Wrap it tightly in plastic wrap and then in aluminum foil; it will keep well in the freezer for up to 3 months. To reheat, simply bake it at 325°F (160°C) until heated through, which usually takes about 30-40 minutes from frozen, ensuring the cheesy goodness remains intact.
What if my casserole turns out too greasy?
To prevent a greasy outcome, using a leaner ground beef or draining excess fat after cooking the meat is essential. If you notice it’s still oily, consider blotting the top with a paper towel before adding the cheese. This step helps keep your Low Carb Philly Cheesesteak Casserole light and not overly rich.
Are there dietary considerations for this recipe?
This dish is a fantastic low-carb and high-protein meal, suitable for most diets. However, if you’re cooking for someone with dairy allergies or lactose intolerance, I recommend using lactose-free cream cheese and cheese alternatives. You can also adjust the spices to match any dietary restrictions while keeping the same savory profile.
Can I make this casserole ahead of time?
Certainly! You can prepare the casserole components—sautéing vegetables and cooking the beef—up to 24 hours in advance. Keep them stored in the refrigerator, then assemble and bake right before serving. This makes your cooking process super convenient, especially on busy days!
