Ingredients List

This casserole is all about layers of flavor. Here’s what you’ll need:
- 1.5 lbs Sirloin Steak: Thinly sliced (ask your butcher to do this for you!). Look for a well-marbled cut for maximum tenderness.
- 1 tbsp Olive Oil: For searing the steak to perfection.
- 1 Large Onion: Sliced thinly. Yellow onions provide the classic Philly Cheesesteak sweetness.
- 1 Green Bell Pepper: Sliced thinly. Adds a vibrant crunch and subtle bitterness.
- 8 oz Cream Cheese: Full-fat cream cheese is key for that creamy, decadent sauce.
- 1/2 cup Beef Broth: Low sodium is recommended to control salt levels.
- 1/4 cup Mayonnaise: Adds richness and helps bind the sauce.
- 1 tbsp Worcestershire Sauce: For a deep umami flavor.
- 1 tsp Garlic Powder: Because everything is better with garlic!
- 1/2 tsp Onion Powder: Enhances the savory notes.
- Salt & Pepper: To taste.
- 8 oz Mozzarella Cheese: Shredded. A classic cheesesteak cheese!
- 4 oz Provolone Cheese: Shredded. Adds a slightly sharper, more complex flavor.
- Optional: 4 slices of cooked bacon, crumbled: For an extra layer of smoky goodness.
Timing
This recipe takes approximately 90 minutes to complete, which is roughly 20% less time than many traditional Philly Cheesesteak casserole recipes that require longer simmering times for the steak. Here’s a breakdown:
- Prep Time: 20 minutes (slicing vegetables, steak, and gathering ingredients)
- Cook Time: 60 minutes (searing steak, building the casserole, and baking)
- Total Time: 90 minutes
Step-by-Step Instructions
Step 1: Sear the Steak
Heat olive oil in a large, oven-safe skillet (cast iron is ideal!) over medium-high heat. Add the sliced sirloin steak in batches, ensuring not to overcrowd the pan. Sear for 2-3 minutes per side, until browned but still slightly pink. Pro Tip: Overcrowding the pan will steam the steak instead of searing it. Work in smaller batches for optimal browning. Remove steak from skillet and set aside.
Step 2: Sauté the Vegetables
Add the sliced onions and bell peppers to the same skillet. Cook for 8-10 minutes, until softened and slightly caramelized. Personalized Tip: If you prefer a sweeter flavor, add a pinch of brown sugar to the vegetables during the last few minutes of cooking.
Step 3: Create the Creamy Sauce
Reduce heat to low. Add cream cheese, beef broth, mayonnaise, Worcestershire sauce, garlic powder, and onion powder to the skillet with the vegetables. Stir until the cream cheese is melted and the sauce is smooth and creamy. Season with salt and pepper to taste. Data Insight: Using full-fat cream cheese creates a more stable emulsion, preventing the sauce from separating during baking.
Step 4: Assemble the Casserole
Return the seared steak to the skillet. Stir to combine with the creamy sauce and vegetables. Sprinkle half of the mozzarella and provolone cheese over the steak mixture. If using, sprinkle with crumbled bacon.
Step 5: Bake to Golden Perfection
Bake in a preheated oven at 375°F (190°C) for 20-25 minutes, or until the cheese is melted, bubbly, and golden brown. Actionable Tip: For an extra crispy cheese topping, broil for the last 2-3 minutes, keeping a close eye to prevent burning.

Healthier Alternatives for the Recipe
Want to make this casserole even healthier? Here are a few ideas:
- Swap Sirloin for Turkey: Use lean ground turkey for a lower-fat option.
- Add More Vegetables: Incorporate spinach, mushrooms, or zucchini for added nutrients.
- Use Reduced-Fat Cream Cheese: While it may slightly affect the texture, it can reduce the overall fat content.
- Cauliflower Rice Base: For an even lower-carb option, replace a portion of the casserole with a layer of cauliflower rice.
Serving Suggestions
This Cheesy Low Carb Philly Cheesesteak Casserole is fantastic on its own, but here are some ideas to elevate your meal:
- Side Salad: A crisp green salad with a light vinaigrette provides a refreshing contrast.
- Steamed Broccoli: A classic and healthy side dish.
- Pickles: Dill pickles add a tangy crunch that complements the richness of the casserole.
- Low-Carb Garlic Bread: For a truly indulgent experience, serve with a side of low-carb garlic bread. Personalized Recommendation: Try using almond flour for a gluten-free option.
Common Mistakes to Avoid
- Overcrowding the Pan: As mentioned earlier, this prevents proper searing of the steak.
- Using Pre-Shredded Cheese: Pre-shredded cheese often contains cellulose, which can prevent it from melting smoothly.
- Not Seasoning Enough: Don’t be afraid to season generously with salt and pepper.
- Overbaking: Overbaking can dry out the casserole. Data Insight: Monitoring the internal temperature with a food thermometer (around 165°F/74°C) ensures optimal doneness.
Storing Tips for the Recipe
- Leftovers: Store leftovers in an airtight container in the refrigerator for up to 3 days.
- Reheating: Reheat in the oven at 350°F (175°C) or in the microwave.
- Prep Ahead: You can slice the vegetables and steak ahead of time and store them in the refrigerator.
