Ingredients

Scale

Meat and Vegetables

  • 1 lb thinly sliced steak (such as ribeye or sirloin)
  • 1 cup sliced bell peppers (mixed colors)
  • 1 cup sliced onions

Base and Broth

  • 3 cups cauliflower rice (or substitute with cooked regular rice or pasta)
  • 1 cup beef broth

Cheese and Seasonings

  • 1 ½ cups shredded cheese (Provolone or Cheddar recommended)
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon paprika

Instructions

  1. Prepare the Steak and Vegetables: Heat a large skillet over medium-high heat. Add the thinly sliced steak and cook until browned, about 3-4 minutes. Add the sliced bell peppers and onions to the skillet and sauté together with the steak until vegetables are tender, about 5 minutes. Season with salt, black pepper, garlic powder, and paprika while cooking to enhance the flavors.
  2. Combine with Cauliflower Rice and Broth: Preheat your oven to 375°F (190°C). In a large mixing bowl, combine the sautéed steak and vegetables with the cauliflower rice and beef broth. Mix thoroughly until everything is well incorporated.
  3. Assemble the Casserole: Transfer the mixture into a greased baking dish, spreading it out evenly. Sprinkle the shredded cheese evenly over the top to create a gooey cheese layer.
  4. Bake the Casserole: Place the baking dish in the preheated oven and bake uncovered for 20-25 minutes, or until the cheese is fully melted and bubbly with a golden brown color.
  5. Serve and Enjoy: Remove the casserole from the oven and let it rest for 5 minutes before serving. This allows the casserole to set slightly for easier portioning and better flavor distribution. Serve warm as a satisfying main dish.

Notes

  • You can substitute cauliflower rice with regular cooked rice or pasta if preferred.
  • Provolone cheese gives the most authentic Philly cheesesteak flavor, but Cheddar or a cheese blend works well too.
  • To make it spicier, add sliced jalapeños or a dash of hot sauce before baking.
  • Leftovers keep well in the fridge for up to 3 days and reheat nicely in the oven or microwave.
  • For a keto-friendly version, ensure the cauliflower rice is used instead of traditional rice or pasta.
