• Cream Cheese
  Creates a creamy, smooth texture in the sauce, helping it cling to the steak and provolone while adding a mild tang.

How To Make This Carnivore Recipe

This casserole comes together quickly, making it an excellent choice for busy weekdays.

The recipe doubles simply, which also makes it a fantastic option when you want to impress your guests. It's a true crowd-pleaser!

Start by seasoning the shaved steak with salt, pepper, and garlic powder if using, then slice it into bite-sized pieces.

In a large skillet over medium heat, melt two tablespoons of butter and cook the steak until it's lightly browned, stirring occasionally to ensure even cooking.

While the steak cooks, preheat your oven to 350°F and begin preparing the cheese sauce.

To make the cheese sauce, melt the remaining tablespoon of butter in a small saucepan over medium heat. Add the beef broth and Worcestershire sauce, if you're using it, and bring the mixture to a simmer.

Reduce the heat to medium and whisk in the room temperature cream cheese, stirring frequently until it's fully melted and incorporated into the broth.

Lower the heat to a gentle simmer, then add half of the shredded provolone cheese.

Continue to cook, stirring until the cheese is completely melted and the sauce is smooth.

Next, combine the cheese sauce with the cooked steak in the skillet, stirring until everything is evenly coated.

Transfer the mixture to a casserole dish and top it with the remaining provolone cheese. Bake the casserole for about 30 minutes, or until it's hot and bubbly.

For a golden, slightly crisp top, place it under the broiler on high for 3 to 5 minutes. Serve hot for the best texture and flavor.

Leftovers can be stored in an airtight container in the refrigerator for up to three days, though freezing isn't recommended as the cheese sauce.

Tips and Variations

• Choose Your Beef Wisely
  I used shaved beef steak in this casserole because it cooks quickly and stays tender, making it perfect for layering with cheese. However, you can easily substitute it with thinly sliced sirloin, ribeye, or flank steak. If you're looking for a more budget-friendly or simpler option, ground beef works just as well-just be sure to drain any excess fat before adding the cheese sauce.
  
• Use Room Temperature Cream Cheese
  Let your cream cheese sit out for a bit before adding it to the sauce. This helps it melt more smoothly and prevents clumps in your cheese mixture.
  
• Avoid Overbaking
  Bake the casserole just until it's hot and bubbly, then finish it under the broiler for that golden top. Over-baking can cause the cheese to separate or become greasy.
  
• Customize to Your Preference
  Want more richness? Add a splash of heavy cream to the cheese sauce. Prefer a different flavor profile? Swap provolone for mozzarella, white cheddar, or even a mix of your favorites.
  
• Carnivore but Flexible? If you're not strict carnivore, consider making our keto version that includes sautéed mushrooms and caramelized onions.
