We're rounding out Week 2 of our Cook Once 5-day Meal Plans today with another 30-minute dinner that can be made in one pot! This easy meal was inspired by the popularity of the Philly Cheesesteak loaded fries from the Cook Once book. We wanted to take those classic flavors and turn them into a weeknight meal that you could make even on the busiest of nights – and this keto Philly cheesesteak skillet delivers!

How to Make this Keto Philly Cheesesteak Skillet

You can make this Philly cheesesteak skillet with just a few simple steps:

  1. Saute the vegetables. First, you'll thinly slice an onion, a red bell pepper, a green bell pepper, and 8 ounces of cremini mushrooms. If you're a mushroom hater, you can leave them out, but we found that they make this meal a little more complete and help up the veggie ratio. Once the veggies are sliced, you'll add them to a hot pan with some olive oil, and saute for about 5-7 minutes, until they are all browned and the onions are slightly caramelized. Then, you'll remove them from the pan.
  2. Cook the ground beef. Once the veggies are done, you'll cook the ground beef in the same pan for about 5 minutes. Once it is browned, drain off the excess fat.
  3. Add everything back to the pan. Next, you'll add the veggies back to the pan then stir in the beef broth, dijon mustard, and coconut aminos. This will help give the dish more flavor. Let everything cook for about 3-4 minutes, until it is bubbling, to let the flavors infuse.
  4. Layer on the cheese. The last step is also the most important – adding cheese! Layer 6 slices of cheese over top of the beef, then either put a lid on the pan or turn on your oven's broiler and place the skillet under it for 1-2 minutes, until the cheese is melted and browned. Enjoy!

This Philly cheesesteak skillet makes a fantastic meal on its own, but would also be great served over cauliflower rice or alongside a green salad. If you're not following a Keto or low-carb diet, you could also use this as the filling for a sandwich, serve it over white rice, or make Philly cheesesteak stuffed potatoes. We hope you love this easy meal!

    This was INCREDIBLE! Used beef bone broth for extra nutrients, and served alongside homemade garlic bread made with crusty sourdough! YUM

    This was so tasty! The Dijon makes the flavor of the beef so rich and delicious. I just wish the nutrition info was with it like in the cook book.
