However, it is also relatively calorie- and fat-dense because of the beef, cream cheese, and provolone. Keeping serving sizes appropriate and pairing it with non-starchy vegetables or a fresh salad can help create a balanced meal.

Does Keto Philly Cheesesteak Casserole Fit a High Protein Lifestyle?

Yes, this casserole is particularly suitable for a high-protein, low-carb lifestyle, with approximately 35.8 g protein per serving. The main protein source is ground beef, while cream cheese and provolone contribute additional protein and richness.

My Personal Experience

• The beef makes this casserole wonderfully hearty.
  Seasoned ground beef gives the dish a rich, savory base that holds up beautifully under the melted cheese.
  Each spoonful feels substantial enough for a satisfying dinner.
• The peppers add a fresh contrast.
  Softened bell peppers bring sweetness and color to the rich beef mixture.
  Sautéing them first keeps them tender rather than undercooked.
• The cream cheese creates a smooth filling.
  Melting cream cheese with chicken bone broth produces a creamy coating for the beef and vegetables.
  It helps bind the casserole together without needing a traditional flour-based sauce.
• The provolone topping is the finishing touch.
  Six slices of provolone create a gooey, savory layer across the surface.
  A few minutes under high heat can give the cheese a beautifully browned finish.

Common Mistakes to Avoid:

1. Adding raw vegetables directly to the casserole — Sauté the peppers and onion first so they become properly tender.
2. Boiling the cream cheese mixture — Stir the cream cheese and broth continuously and remove it from the heat once smooth to prevent burning or excessive drying.
3. Cutting the peppers too large or too small — Use reasonably even slices so they cook consistently and remain noticeable in the finished casserole.
4. Skipping the resting period — Let the baked casserole sit for about 5–10 minutes before serving so the flavors settle and the filling firms slightly.

Required Equipment:

• Large skillet — Provides enough surface area to brown the beef and sauté the vegetables evenly.
• 8 × 11.5-inch baking dish — Gives the casserole an appropriate shape and depth for even baking.
• Spatula — Makes it easy to break up the beef and stir the vegetables.
• Small saucepan or skillet — Helps melt the cream cheese with broth smoothly.
• Chef’s knife — Makes slicing the peppers and onion quick and consistent.
• Cutting board — Provides a stable surface for preparing the vegetables.
• Measuring cups and spoons — Keep the seasonings and liquids properly balanced.

Storage Instructions:

Store leftover baked casserole in an airtight refrigerator-safe container or cover the baking dish tightly. The source states that baked or assembled casserole can be refrigerated for approximately 5–6 days.

For longer storage, the assembled casserole can be tightly wrapped and frozen for approximately 90–100 days according to the source. For best texture, thaw it in the refrigerator before baking rather than placing a frozen casserole directly into a hot oven.

To reheat leftovers, warm them in the microwave or in a 350°F / 175°C oven until heated through.

Because the casserole remains protein-rich after refrigeration or freezing, portion leftovers into individual containers for convenient high-protein meals.

📝 Ingredients

Casserole

• 2 lb (907 g) ground beef
• 3 large bell peppers, thinly sliced
• 1 large onion, thinly sliced
• 4 oz (113 g) cream cheese
• ¼ cup chicken bone broth
• 6 slices provolone cheese
• 2 teaspoons sea salt
• ½ teaspoon garlic powder
• ½ teaspoon black pepper
• 1 teaspoon smoked paprika
• ½ tablespoon Italian seasoning

Ingredient Notes

• Beef: Ground beef is used in the original recipe, but thinly sliced shaved steak can also be used.
• Provolone: Use sliced or grated provolone; white cheddar, Colby Jack, or mozzarella can also work as alternatives.
• Bell peppers: Any color or a combination of colors can be used.
• Onion: Yellow, red, or sweet onion works well.
• Cream cheese: Full-fat cream cheese provides the creamy texture and richness expected in the casserole.

Directions

1. Preheat the oven.
   Set the oven to 350°F / 177°C. Prepare an approximately 8 × 11.5-inch baking dish; stoneware can be used without additional oil, while other dishes can be lightly greased.
2. Brown the beef.
   Heat a large skillet over medium-high heat. Add the ground beef and cook while breaking it apart with a spatula until browned and cooked through.
3. Season the beef.
   Add sea salt and black pepper while the beef cooks. Continue stirring occasionally so the beef cooks evenly.
4. Sauté the vegetables.
   Add the sliced bell peppers and onion to the cooked beef. Sprinkle in garlic powder, Italian seasoning, and smoked paprika. Cook over medium heat until the vegetables become slightly soft but still retain some texture.
5. Make the creamy mixture.
   Add the chicken bone broth and cream cheese to the skillet. Stir continuously over low to medium-low heat until the cream cheese melts and creates a smooth, creamy mixture.
6. Avoid overheating the cream cheese.
   Once the mixture is smooth, remove it from the heat promptly. Do not allow the cream cheese and broth mixture to boil, as it can burn or become excessively dry.
7. Transfer to the baking dish.
   Spoon the beef and vegetable mixture into the prepared baking dish and spread it into an even layer.
8. Add the provolone.
   Arrange the six provolone slices over the surface, allowing them to overlap slightly so the filling is well covered.
9. Bake.
   Place the dish in the preheated 350°F / 177°C oven and bake until the provolone is fully melted and bubbling. The source indicates approximately 35–40 minutes for a prepared casserole.
10. Brown the cheese if desired.
    For a crispier golden cheese topping, move the casserole to the top rack and use high heat for approximately 5 minutes, watching closely to prevent burning.
11. Rest before serving.
    Remove the casserole and let it stand undisturbed for 5–10 minutes. This allows the filling to settle and makes serving easier.

High-protein cooking tip: Keep the beef as the main component and avoid diluting the casserole with excessive vegetables or sauce if your goal is to maintain a protein-focused serving.
