- 2 large bell peppers (green, red, or a mix), diced: Colorful and crunchy, contributing to the vibrant presentation.
- 2 cloves garlic, minced: A must-have for aroma and flavor that elevates any dish.
- 8 oz cream cheese: Creamy and luscious, it helps bind all flavors and adds a decadent texture.
- 2 tbsp Worcestershire sauce: Its umami-rich taste brings all the ingredients together seamlessly.
- Salt and pepper to taste: Essential for enhancing all the flavors.
- 8 oz provolone cheese, sliced: Melts beautifully for that gooey cheesesteak experience.
- 1½ cups mozzarella cheese, shredded: Offers a stretchy, delightful texture when baked.
- 1 tbsp olive oil: For sautéing the veggies, adding a layer of flavor.
- 2 tbsp fresh parsley, finely chopped (for garnish): Bright and fresh, enhancing presentation and taste.
Step-by-Step Directions
-
Preheat your oven to 350°F (175°C). Begin by spraying a 9×13 baking dish with non-stick spray to ensure easy removal of the casserole later.
-
Heat olive oil in a large skillet over medium heat. Add the diced onions and bell peppers, sautéing them until they are soft and fragrant, which typically takes around 5-6 minutes.
-
Once the onions and peppers are tender, add the minced garlic. Continue to sauté for an additional 30 seconds until the garlic is fragrant but not browned.
-
Next, add the ground beef to the skillet, seasoning it generously with salt and pepper. Cook the beef until it is nicely browned, about 7-8 minutes, breaking it up into smaller pieces as it cooks.
-
Stir in the Worcestershire sauce, which will enhance the savory flavors of the beef and veggies.
-
Reduce the heat and add the cream cheese to the browned mixture. Stir until the cream cheese has melted and combined evenly, creating a creamy filling.
-
Transfer the mixture into the prepared baking dish. Layer the sliced provolone cheese over the top, followed by a generous sprinkling of shredded mozzarella cheese.
-
Bake in the preheated oven for 20-25 minutes, or until the cheeses are melted, bubbly, and slightly golden.
-
Once baked, let the casserole rest for 5 minutes before serving. This helps it set and makes it easier to cut and serve.

To elevate your Low Carb Philly Cheesesteak Casserole, consider these additional tips:

- If you’re a fan of mushrooms, sauté some sliced mushrooms along with the onions and peppers for an earthy addition.
- For a bit of crunch, garnish the casserole with crispy fried onions just before serving.
Serving Suggestions & Pairings
