Key Ingredients & Substitutions
Ribeye or Sirloin Steak: Ribeye has great flavor and tenderness, but sirloin is a leaner option if you prefer. You can also use flank steak or even ground beef if that’s what you have on hand.
Olive Oil or Avocado Oil: Both oils work well for cooking, but avocado oil has a higher smoke point. If you’re looking for a different flavor, try using coconut oil, though it may alter the taste slightly.
Bell Peppers: These add sweetness and color! If you’re not a fan of bell peppers, zucchini or mushrooms can be a great alternative. Just remember they have different cooking times, so adjust accordingly!
Provolone or Mozzarella Cheese: Provolone adds a nice tang, but mozzarella keeps it super melty. If you’re aiming for dairy-free, go for vegan cheese or skip it altogether and add nutritional yeast for a cheesy flavor!
How Do I Make Sure My Steak Stays Tender and Flavorful?
Cooking steak well is key to getting that juicy, tender bite. Here’s what to do:
- Make sure your skillet is really hot before adding the meat; this helps in browning.
- Season your steak while it’s cooking for more flavor. Salt helps draw out moisture, enhancing taste.
- Avoid overcooking! Thin slices cook quickly, usually around 3-5 minutes will do.
- Let your steak rest in the skillet after cooking. This keeps it juicy!
Follow these tips, and you’ll have a deliciously satisfying meal every time!

- 1 lb thinly sliced ribeye steak or sirloin steak
- 1 tablespoon olive oil or avocado oil
- 1 small onion, thinly sliced
- 1 red bell pepper, thinly sliced
- 1 green bell pepper, thinly sliced

- 2 cloves garlic, minced
- Salt and freshly ground black pepper, to taste
- 1/2 teaspoon dried oregano (optional)

How Much Time Will You Need?
This recipe takes about 10-15 minutes to prep and cook, plus an additional 2-3 minutes for the cheese to melt. In total, you can enjoy this delicious meal in about 20 minutes—perfect for a quick weeknight dinner!
Step-by-Step Instructions:
1. Heat the Skillet:
Start by heating the oil in a large cast-iron skillet over medium-high heat. This will give your veggies and steak a nice sear! Make sure the oil is hot but not smoking.
2. Sauté the Vegetables:
Once the oil is ready, add the sliced onions and bell peppers to the skillet. Sauté them until they’re soft and fragrant—this usually takes about 4-5 minutes. Stir occasionally to prevent sticking.
3. Add Garlic:
Next, add the minced garlic and cook for an additional minute until it’s nice and aromatic. Stir it in with the onions and peppers; the delicious smell will fill your kitchen!
4. Cook the Steak:
Now, push the veggies to the side of the skillet. Add the sliced steak to the empty space, season with salt, pepper, oregano, and basil. Cook until the steak is browned and fully cooked through—around 3-5 minutes. It’s okay to stir occasionally to break it up and ensure even cooking.
5. Combine Everything:
Give the skillet a good mix to combine the steak and vegetables. This will allow all those amazing flavors to meld together.
6. Melt the Cheese:
Reduce the heat to low. Sprinkle the shredded provolone cheese evenly over the top of the mixture. Cover the skillet with a lid or some foil and let it sit for about 2-3 minutes to melt the cheese.
7. Serve and Enjoy:
Once the cheese is melted and bubbling, take your skillet off the heat. Serve it hot directly from the skillet or alongside your favorite keto-friendly options like cauliflower rice or a fresh green salad. Enjoy your delicious, keto-friendly Philly cheesesteak skillet!
This recipe brings you all the delicious flavors of a classic Philly cheesesteak without the carbs. Enjoy every bite!
Can I Use Frozen Steak in This Recipe?
Yes, you can, but be sure to thaw it first! Thaw your frozen steak in the fridge overnight or quickly in a sealed plastic bag submerged in cold water. Pat it dry before cooking to avoid excess moisture.
Can I Make This Dish Vegetarian?
Absolutely! Substitute the steak with sautéed mushrooms, tempeh, or even tofu for a delicious vegetarian version. Just make sure to adjust cooking times accordingly for the vegetables to ensure they’re nicely cooked.
How Do I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. Reheat on the stove over low heat or in the microwave, stirring occasionally to ensure even warming!
What Can I Serve with My Philly Cheesesteak Skillet?
This dish is great on its own, but you can serve it with cauliflower rice or zoodles (zucchini noodles) for a complete meal. A simple side salad also works wonderfully!
