How to Make Cheesy Low Carb Philly Cheesesteak Casserole
Step 1: Prepare the Beef and Vegetables
Start by heating olive oil or butter in a large skillet over medium-high heat. Add the sliced onions and bell peppers, cooking until they soften and begin to caramelize, about 7–8 minutes. Toss in the mushrooms and cook for another 3 minutes. Transfer the veggies to a bowl, then add the thinly sliced beef to the same skillet. Season with salt, pepper, garlic, and your preferred spices. Cook the beef until browned but still tender, about 4–5 minutes.
Step 2: Mix the Creamy Base
In a separate bowl, blend the cream cheese or heavy cream with a pinch of salt and pepper. This mixture will add moisture and a luscious mouthfeel to the casserole without spiking carb content.
Step 3: Combine Ingredients
Return the cooked veggies to the skillet with the beef, stirring everything together evenly. Pour in the creamy mixture and fold to combine thoroughly for consistent flavor and texture throughout the casserole.
Step 4: Assemble the Casserole
Preheat your oven to 350°F (175°C). Transfer the beef and vegetable mixture into a greased casserole dish. Generously top with shredded provolone or mozzarella cheese, spreading it evenly over the surface.
Step 5: Bake to Perfection
Bake uncovered for 20–25 minutes until the cheese has melted and is bubbling with golden spots. Let it rest for 5 minutes before serving so the casserole can set, ensuring clean slices and optimal flavor concentration.
Pro Tips for Making Cheesy Low Carb Philly Cheesesteak Casserole
- Slice meat thinly: This ensures the beef cooks quickly and remains tender, just like a traditional Philly cheesesteak.
- Don’t overcrowd the pan: Cooking the veggies and meat separately or in batches helps achieve better caramelization and flavor.
- Use fresh, high-quality cheese: It melts better and gives the casserole that rich, irresistible texture.
- Let it rest: Allowing the casserole to cool slightly helps it hold together when slicing and serving.
- Customize spices: Experiment with smoked paprika, garlic powder, or even a dash of Worcestershire sauce for depth.
