(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
Before we start cooking, let’s take a look at what you’ll need to create this flavor-packed casserole. These simple ingredients are easy to find and even easier to prepare.
Ground beef or sliced ribeye steak – The heart of the dish; juicy and tender meat makes all the difference.
Green bell peppers and onions – Classic Philly cheesesteak veggies that add texture and sweetness.
Mushrooms (optional) – Adds an earthy flavor and extra nutrition.
Cream cheese – For that creamy, rich consistency that binds everything together.
Provolone or mozzarella cheese – Melts beautifully and gives that signature cheesy stretch.
Heavy cream – Adds extra creaminess to the sauce.
Garlic and seasonings – Salt, pepper, and a pinch of paprika or Worcestershire sauce for depth of flavor.
Pro tip: Don’t skimp on the cheese—it’s the secret weapon that makes this casserole irresistibly gooey and delicious!
Let’s Get Started
Now that you’ve got everything ready, it’s time to bring this Low Carb Philly Cheesesteak Casserole to life. Follow these simple steps:
Preheat your oven to 375°F (190°C). Grease a medium-sized baking dish with butter or nonstick spray.
Cook the meat: In a large skillet over medium heat, brown the ground beef (or cook thinly sliced steak until just tender). Drain any excess grease.
Sauté the veggies: Add chopped onions, bell peppers, and mushrooms to the pan. Cook until softened and fragrant—about 5 minutes.
Mix in the creaminess: Stir in the cream cheese, heavy cream, garlic, and seasonings. Mix until the cream cheese melts into a luscious sauce.
Layer it up: Transfer the mixture to your baking dish, then top generously with provolone or mozzarella cheese.
Bake for 20 minutes or until the cheese is bubbly and golden.
Serve hot, garnished with a sprinkle of parsley or crushed red pepper for a little kick.
The result? A creamy, cheesy, meaty masterpiece that feels indulgent but fits your low-carb goals perfectly.

FAQs
Can I make this casserole ahead of time?
Absolutely! Prepare the casserole as directed, but don’t bake it. Cover tightly and refrigerate for up to 24 hours. When ready to serve, bake as usual.
Can I use ground turkey instead of beef?
Yes, ground turkey works perfectly and makes it a bit leaner while keeping it flavorful.
What’s the best cheese for this recipe?
Provolone is the classic choice, but mozzarella, Swiss, or even a blend of cheddar and Monterey Jack are delicious options.
How can I make it even lower in carbs?
Skip the onions or reduce them slightly—they add natural sugar. You can also use heavy cream sparingly or replace it with almond milk.
Can I freeze it after baking?
Yes! Just cool it completely, wrap tightly, and freeze. It reheats wonderfully for a quick meal later.
