Written by admin


  • 1.5 pounds thinly sliced beef (sirloin or ribeye)
  • 2 tablespoons olive oil
  • 1 green bell pepper, thinly sliced
  • 1 red bell pepper, thinly sliced
  • 1 medium onion, thinly sliced
  • 8 ounces mushrooms, sliced
  • 3 cloves garlic, minced
  • Salt and pepper to taste
  • 1 teaspoon Italian seasoning
  • 4 slices provolone or Swiss cheese


  1. Prepare the Beef:
    • Pat the beef slices dry with paper towels to remove excess moisture. Season with salt and pepper.
  2. Cook the Beef:
    • In a large skillet over medium-high heat, add 1 tablespoon of olive oil. Cook the sliced beef in batches until browned on both sides. Remove the beef from the skillet and set it aside.
  3. Sauté Vegetables:
    • In the same skillet, add another tablespoon of olive oil. Sauté the sliced green and red bell peppers, onions, mushrooms, and minced garlic until the vegetables are tender.
  4. Combine Beef and Vegetables:
    • Return the cooked beef to the skillet with the sautéed vegetables. Toss everything together to combine.
  5. Season:
    • Season the mixture with Italian seasoning, salt, and pepper. Adjust the seasoning to taste.
  6. Top with Cheese:
    • Lay the slices of provolone or Swiss cheese over the beef and vegetable mixture. Cover the skillet with a lid and let it melt for a couple of minutes until the cheese is gooey and melted.
  7. Serve:
    • Once the cheese is melted, remove the skillet from heat.
  8. Garnish (Optional):
    • Garnish with fresh herbs like parsley or chives if desired.
  9. Serve Warm:
    • Serve the Keto Philly Cheesesteak straight from the skillet. You can enjoy it as is or over a bed of cauliflower rice for a low-carb option.

This one-pan Keto Philly Cheesesteak Skillet is a quick and flavorful dish that captures the essence of a classic Philly cheesesteak without the carbs. Feel free to customize it with your favorite Keto-friendly ingredients!
