Dietary Considerations

To make your casserole even tastier, consider adding:
– Sliced mushrooms for a rich, earthy flavor.
– Jalapeños for a spicy kick.
– Worcestershire sauce for added umami depth.

Step-by-Step Instructions
Preheating the Oven
First, set your oven to 350°F (175°C). This step is key for even cooking. Preheating helps the casserole cook right.
Preparing the Vegetables
Next, take a large skillet and add a tablespoon of olive oil. Heat it over medium. Slice one medium onion and one green bell pepper thinly. Add them to the skillet. Cook until soft, about 5-7 minutes. Then, add two minced garlic cloves. Stir for one more minute. This brings out all the great flavors. Once done, remove the veggies and set them aside.
Cooking the Beef
Now, use the same skillet for the beef. Add one pound of thinly sliced beef. Season with salt, pepper, one teaspoon of paprika, and one teaspoon of Italian seasoning. Cook for 5-8 minutes. Stir often to break apart the meat. You want it browned and cooked through.
Combining Ingredients
In a mixing bowl, combine one cup of heavy cream and the cooked vegetables. Add ¾ cup of shredded provolone cheese to the mix. Then, stir in the cooked beef until everything is mixed well. This step makes each bite full of flavor.
Layering the Casserole
Transfer the beef and veggie mix into a greased 9×13 inch baking dish. Spread it out so it’s even. Next, top it off with the remaining provolone cheese and one cup of shredded mozzarella cheese. This will give you a nice cheesy topping.
Baking the Dish
Now, place the baking dish in the oven. Bake for 25-30 minutes. Look for bubbly and golden cheese on top. This is when the casserole is ready to come out.
Serving Suggestion
Once baked, take it out of the oven. Let it cool for a few minutes. This helps with serving. Garnish with chopped fresh parsley for a pop of color. Now, it’s time to enjoy your low-carb Philly cheesesteak casserole!
Tips & Tricks
How to Achieve the Perfect Cheese Topping
To get that gooey cheese topping, use a mix of provolone and mozzarella. This blend gives great flavor and nice texture. Add the provolone to the beef mix and save the mozzarella for the top layer. Bake until the cheese bubbles and turns golden. This gives a nice crust that everyone will love.
Best Practices for Tender Beef
For tender beef, slice it thin. Use flank steak or sirloin for the best results. Make sure to season it well while cooking. This adds flavor and helps keep it juicy. Cook it just until it’s browned, about 5-8 minutes. Overcooking can make it tough, so keep an eye on it.
Time-Saving Prep Tips
To save time, you can prep some ingredients ahead. Slice the onions and peppers the night before. This way, they are ready to go when you start cooking. You can also use pre-sliced beef if it’s available. This cuts down your prep time and makes the dish easier to put together.
Pro Tips
- Tip for Beef Selection: Choose high-quality cuts like flank steak or sirloin for a tender and flavorful casserole.
- Tip for Creaminess: For an extra creamy texture, consider adding a little cream cheese to the heavy cream mixture.
- Tip for Vegetables: Feel free to mix in other vegetables like mushrooms or spinach for added nutrition and flavor.
- Tip for Cheese: Experiment with different cheese blends, such as cheddar or gouda, for unique flavor twists.

Variations
Alternative Protein Sources
You can swap the beef for other meats. Try thinly sliced chicken or turkey. These options work well and keep the dish tasty. You can also use ground beef or turkey for a different texture. For a fun twist, try pork. Each protein brings its own flavor, making your casserole unique.
Vegetarian or Vegan Options
To make this dish vegetarian, replace the beef with mushrooms or tempeh. Both options add a hearty feel. Use vegetable broth in place of heavy cream for a vegan version. Nutritional yeast adds a cheesy flavor without dairy. You can also load up on veggies like zucchini or eggplant to add more depth.
Spice Level Adjustments
If you like heat, add red pepper flakes or jalapeños to your meat mix. These spices will give your casserole a kick. For a milder taste, leave out any hot ingredients. You can also add sweet bell peppers for a nice balance. Adjusting spice levels helps you create your perfect casserole.
