How to Make Keto Philly Cheesesteak Casserole
- Preheat your oven to 350°F (175°C) and lightly grease a 9×13 baking dish to ensure easy serving later.
- Prep the vegetables: Dice the onion, mince the garlic, slice the mushrooms, and cut the bell peppers into strips. This will add that vibrant color and flavor to your dish.
- Brown the ground beef in a skillet over medium heat until fully cooked through, about 7-10 minutes; drain any excess fat to keep your casserole from becoming greasy.
- Sauté the bell peppers, onion, and garlic in the same skillet until softened, approximately 5-7 minutes, allowing those lovely aromas to fill your kitchen.
- Add mushrooms to the mixture and sauté until tender, then mix in the cooked ground beef. Season with salt and pepper to taste for that delicious flavor kick.
- Combine the cream cheese, heavy cream, and half of the mozzarella in a separate saucepan over low heat until melted and smooth, creating a rich, creamy sauce.
- Mix the cheesy sauce with the beef and vegetable mixture until evenly combined; then spread everything into the prepared baking dish, ensuring it’s evenly distributed.
- Top it off with the remaining mozzarella and parmesan cheese, creating a luscious, cheesy crust that’ll melt and brown beautifully.
- Bake in the preheated oven for 15-20 minutes or until the cheese is bubbly and golden brown, filling your home with mouth-watering scents.
- Let sit for 5 minutes before serving; this resting time allows flavors to meld beautifully. If desired, garnish with fresh herbs for a dash of color.
Optional: Add a sprinkle of crushed red pepper flakes for an extra kick!

Storage Tips for Keto Philly Cheesesteak Casserole
Fridge: Keep leftovers in an airtight container for up to 5 days; this will ensure your casserole remains fresh and delicious for meals throughout the week.
Freezer: For longer storage, freeze in oven-safe containers for up to 3 months. When ready to eat, bake straight from the freezer—just add extra cooking time.
Reheating: To maintain the creamy texture, reheat in the oven at 350°F (175°C) for 20-25 minutes, covered with foil; this prevents the cheese from over-browning while the casserole warms through.

Keto Philly Cheesesteak Casserole Recipe FAQs
What type of bell peppers should I use?
You can use any color bell peppers you prefer—red, yellow, or green! Each type brings its own unique flavor profile, with red being sweeter and yellow adding a hint of sweetness too. I often like to mix them for a vibrant dish!
How long can I store leftovers?
Keep your delicious Keto Philly Cheesesteak Casserole in an airtight container in the fridge for up to 5 days. To maintain the best flavor and texture, I recommend reheating in the oven for that perfect melt rather than in the microwave.
Can I freeze the casserole?
Absolutely! You can freeze the casserole in oven-safe containers for up to 3 months. When ready to enjoy, bake it straight from the freezer—just make sure to increase the cooking time by about 10–15 minutes, covered with foil so the cheese doesn’t burn.
What if my casserole browns too quickly?
If you notice the top of your casserole getting too brown while baking, don’t panic! Simply cover it with aluminum foil to shield the cheese from intense heat while allowing the interior to cook through. This way, you still get that golden, bubbly top without burning it.
Is this dish suitable for those with dairy allergies?
For those with dairy allergies or who prefer a dairy-free option, you can substitute the cream cheese and heavy cream with coconut cream and nutritional yeast for that cheesy flavor. Just ensure the other ingredients are also dairy-free.
How can I enhance the flavor of the casserole?
To add extra depth to your Keto Philly Cheesesteak Casserole, consider incorporating spices like smoked paprika or a pinch of crushed red pepper flakes. Sautéing the vegetables longer can also help develop their natural sweetness and flavor complexity!
