Ingredients
- Ground Beef: I choose high-fat content for juicy & tender results. Quality cuts balance richness & savoriness, transforming your casserole into a mouth-watering delight.
- Onion, Diced: Opt for sweet onions. They caramelize beautifully and enhance depth, adding sweetness & complexity with a subtle crunch to your casserole.
- Bell Peppers: Vivid colors equal a spectrum of flavors. Fresh peppers deliver crisp texture and aromatic sweetness, diversifying the casserole’s flavor profile.
- Garlic, Minced: Fresh garlic infuses a robust aromatic essence. It enhances savory notes, tying all ingredients together with a punchy, mouth-watering fragrance.
- Cream Cheese: Essential for creaminess & richness. Ensures the casserole has a smooth and decadent consistency, merging flavors seamlessly.
- Worcestershire Sauce: Adds complexity and depth. Its tangy, savory notes amplify the meaty flavors, offering a sophisticated enhancement to the dish.
- Salt and Pepper: Key for seasoning. Elevates natural flavors and provides balance, ensuring every bite is tasty and satisfying.
- Provolone Cheese: I choose aged for added sharpness. Melted on top, it provides creamy texture and a slightly tangy depth, harmonizing flavors.
- Mozzarella Cheese: Offers stretch and mild creaminess. Use fresh mozzarella for optimal texture and melt, elevating the casserole experience.
- Olive Oil: Go for extra virgin for its fruity notes. It enhances ingredient flavors while ensuring even cooking and a delicate finish.
How to Make
- Prepare the Skillet: Preheat your oven to 350 degrees. Begin by spraying a 9×9 baking dish with non-stick spray to ensure your casserole won’t stick.
- Brown the Beef: Heat a skillet over medium heat and add the ground beef. Cook while crumbling until it’s partially browned but still slightly pink. This step locks in the beef’s juicy texture.
- Add Vegetables & Season: Add the chopped peppers, onions, and garlic to the skillet with seasoned salt. Stir often until the vegetables soften and their aroma fills the kitchen.
- Combine & Drain: Once the beef is cooked through, drain the excess grease and pour the mixture into the prepared baking dish, ready for the next layer of flavor.
- Mix the Egg Blend: In a bowl, whisk together eggs, cream, hot sauce, and Worcestershire sauce until smooth. This mix should be velvety, hinting at the richness it will bring.
- Assemble the Casserole: Pour the egg mixture evenly over the beef and veggies in the baking dish. Tear the provolone cheese into pieces and evenly distribute over the top, promising a melted, cheesy finish.
- Bake to Perfection: Place in the oven, and let it bake until the cheese is bubbly and golden, and the casserole is set, emitting an inviting aroma.
Expert Cooking Tips
- I use freshly grated garlic for a robust, spicy flavor that store-bought can’t match.
- Avoid over-crowding the skillet to ensure the beef browns nicely, enhancing the casserole’s savory taste.
- Gently stir the egg mixture to maintain its light, airy texture, crucial for a fluffy casserole.
- Provolone pulls in silky textures when torn into smaller pieces, allowing even melting.
- Use seasoned salt sparingly to control the dish’s overall saltiness; you can always add more later.
Storage Tips Low Carb Philly Cheesesteak
- Refrigerate leftovers in an airtight container for up to 4 days to preserve freshness and texture.
- Freeze single portions by wrapping them tightly in plastic wrap before placing them in a freezer-safe container.
- Prevent freezer burn by double-wrapping your casserole tightly in foil or using a vacuum-sealed bag.

- For quick reheating, use the microwave but cover the dish with a damp paper towel to retain moisture.

Variations and Substitutions
- Dairy-Free: Use a plant-based cheese and coconut cream to replace Provolone and heavy cream without sacrificing creaminess.
- Gluten-Free: Ensure all spices and ingredients are certified gluten-free to avoid any unexpected gluten exposure.
