Ingredients You’ll Need

For the Beef Mixture:

1½ pounds thinly sliced ribeye steak (or sirloin)
2 tablespoons olive oil
1 large green bell pepper, sliced
1 medium onion, thinly sliced
2 cloves garlic, minced
1 tablespoon Worcestershire sauce
1 teaspoon Italian seasoning
½ teaspoon salt
¼ teaspoon black pepper

For the Cheese Layer:

8 oz cream cheese, softened
¼ cup mayonnaise
¼ cup sour cream
2 cups shredded provolone cheese (or a mix of provolone and mozzarella)
½ cup shredded cheddar cheese

Optional Garnish:

Fresh parsley, chopped
Red pepper flakes

Step-by-Step Instructions

Step 1: Prepare Your Ingredients

Preheat your oven to 375°F (190°C). While the oven heats up, slice your ribeye or sirloin steak into very thin strips. Pro tip: Placing the meat in the freezer for about 20 minutes beforehand makes it easier to slice thinly. Slice your bell pepper and onion into thin strips as well, and mince the garlic.

Step 2: Sauté the Vegetables

Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the sliced bell peppers and onions to the hot pan. Sauté for 5-6 minutes until they begin to soften and the onions become translucent. Add the minced garlic and continue cooking for another 30 seconds until fragrant. Transfer the vegetable mixture to a plate and set aside.

Step 3: Cook the Beef

In the same skillet, add the remaining tablespoon of olive oil. Once hot, add the thinly sliced beef to the pan. Cook for 3-4 minutes, stirring occasionally, until the meat is just browned. Add the Worcestershire sauce, Italian seasoning, salt, and pepper, stirring to combine. Cook for an additional minute to allow the flavors to meld.

Step 4: Combine Beef and Vegetables

Return the sautéed vegetables to the skillet with the beef. Stir to combine all ingredients thoroughly. Remove the pan from heat and set aside.

Step 5: Prepare the Cheese Mixture

In a medium bowl, combine the softened cream cheese, mayonnaise, and sour cream. Mix until smooth and well combined. This creamy mixture will add richness and bind the casserole together.

Step 6: Assemble the Casserole

Spray a 9×13 inch baking dish with non-stick cooking spray. Transfer the beef and vegetable mixture to the baking dish, spreading it evenly. Drop spoonfuls of the cream cheese mixture over the top, then use a spatula to carefully spread it into an even layer. Sprinkle the shredded provolone (or provolone-mozzarella mix) and cheddar cheeses over the top.

Step 7: Bake to Perfection

Place the casserole in the preheated oven and bake for 15-20 minutes, until the cheese is melted, bubbly, and beginning to brown on top. For an extra golden top, you can broil for the final 2 minutes, but watch carefully to prevent burning.

Step 8: Rest and Serve

Remove the casserole from the oven and let it rest for 5 minutes before serving. This short resting period allows the casserole to set slightly, making it easier to serve. Garnish with chopped parsley and red pepper flakes if desired.

Pro Tips for Success

Choose the Right Beef: Ribeye is traditional for Philly cheesesteaks and offers great marbling and flavor, but sirloin is a leaner, more budget-friendly option that works well too.
Slice Meat Properly: For authentic texture, slice the beef as thinly as possible against the grain. If buying pre-sliced meat, look for “shaved steak” or ask your butcher to thinly slice it for you.
Don’t Overcook: The beef will continue cooking in the oven, so it’s best to keep it slightly underdone when sautéing.
Cheese Variations: While provolone is traditional, American or Cheez Whiz fans can substitute those cheeses for an authentic South Philly taste.
Add Mushrooms: For a variation, add 8 oz of sliced mushrooms and sauté them with the peppers and onions.
Control Moisture: If your vegetables or meat release excess liquid during cooking, drain it before assembling the casserole to prevent a soggy result.

Frequently Asked Questions

Can I make this Low Carb Philly Cheesesteak Casserole ahead of time? Absolutely! You can prepare the entire casserole up to the baking step, cover it tightly with plastic wrap, and refrigerate for up to 24 hours. When ready to eat, simply remove from the refrigerator while the oven preheats, then bake as directed, adding about 5-10 minutes to the cooking time.

What’s the best cheese to use for authentic Philly cheesesteak flavor? Provolone is the most traditional cheese for an authentic Philly cheesesteak, but many South Philly purists also use American cheese or Cheez Whiz. For this casserole, the combination of provolone and cheddar provides great flavor while maintaining the low-carb profile.

Can I use ground beef instead of sliced steak? Yes, while not traditional, ground beef works in a pinch and can be more budget-friendly. If using ground beef, choose 80/20 for best flavor and drain excess fat after browning.

Is this recipe suitable for meal prep? Definitely! This casserole reheats beautifully, making it perfect for meal prep. Portion into individual containers after cooling for grab-and-go lunches throughout the week.
