Veggies: you are welcome to omit any veggies you don’t like. If you do leave out one type of vegetable, consider adding extra of a different type of vegetable.
Cheese: this recipe is made with provolone cheese, however you can also use mozzarella cheese or cheddar cheese.
Dairy Free: make this skillet dairy free by leaving off the cheese or by subbing a dairy-free cheese.
What is the Best Type of Meat to Use?
Philly cheesesteaks are most often made with ribeye steak. Look for a ribeye that has lots of marbling and is red in color. Ribeye is typically very tender when cooked.
Another alternative is to use flank steak or sirloin steak. Both of these options are slightly less tender, however they still turn out well. Make sure to cut the steak into small pieces and cut against the grain.

Step by Step Instructions
Slice the veggies. Wash all veggies to remove the dirt. Remove the tops and stems of the bell peppers. Slice them into thin strips that are about ⅛ inch thick.
Next, slice the onion in half, and then place it face down and continue to make small slices by cutting cross wise. Slice the mushrooms into thin slices.
Slice the steak. Place the steak in the freezer for 20-30 minutes prior to cutting. Using a sharp knife and fork, remove all fat. Cut into thin strips (about ¼ inch thick).
Cut the steak against the grain. To do this, look for the small fine lines in the meat, and cut in the opposite direction of these. Here's a helpful video on how to cut steak against the grain.
Cook the steak. Add 1 teaspoon of olive oil to a skillet and set to medium heat. Add the strips of steak, stir frequently and cook until done. The steak is done when it reaches 145F. There may still be some pink in the steak and this is ok as long as it reaches the correct temperature. You are welcome to cook it for longer or shorter time based on personal preference.
Remove the steak and set aside, leaving the juices in the bottom of the skillet.
Add the veggies to the same skillet. Cook over medium heat until tender. This will take about 10-12 minutes. Stir frequently.
Add the steak back into the skillet and mix with the vegetables. (If your skillet is not oven safe, transfer the food to a baking dish that can go in the oven).
Tear the cheese into small pieces and add to the top of the meat and stick in between some of the veggies.
Bake in the oven for 5 minutes or until cheese melts. Boil for 2 minutes. Serve warm.
Refrigerator: store the leftovers in an airtight container in the refrigerator. Eat within 3-4 days. For safe food storage, allow all the steam to release from the hot food, and then refrigerate immediately. More information on safe food storage here!
Freezer: store in an airtight bag or container. Freeze for up to 3 months. For easy reheating, consider freezing in small portions.
Philly Cheesesteak Meal Prep
This philly cheesteak skillet is the perfect lunch or dinner meal prep option. This recipe makes 4 servings and each serving is 1.25 cups. To meal prep this recipe, simply line up 4 Tupperware containers and divide the philly skillet evenly amongst the dishes.
Here's some of my favorite sides I like to add to meal prep containers:
- Black beans (good protein and fiber source)
- White or brown rice (this will add carbs)
- Cauliflower rice (low carb and good fiber source)
- Lettuce (turn it into a salad)
- Sweet potatoes (healthy carb and good fiber source)
Make Ahead Information
To make this an extra easy meal, prep some of the meal ahead of time. Slice all vegetables and store in a zip lock bag. Slice the steak and store in a ziplock bag. Store the cut veggies and steak in the refrigerator for up to 24 hours. This is an easy way to prep some of the skillet the night before!
- Keep it low carb: serve over a bed of cauliflower rice or with a side salad
- Add some carbs: serve with rice or serve on a hoagie bun
- Add extra protein: serve with a side of scrambled eggs or black beans
- Cut the steak against the grain! This will make it much easier to cut and it cooks best this way.
- Don't over cook the steak! Since this recipe will go in the oven after you cook the steak on the skillet, it's ok if there is some pink left in the steak.
- Modify this recipe to your liking- add extra veggies, double the steak, add extra cheese. This recipe is versatile and is hard to mess up.
Frequently Asked Questions
Can this be made with ground beef?
Yes! You can substitute the steak for ground beef. The cooking time of the beef will take longer than the steak.
Is this Philly Cheesesteak Healthy?
This cheesesteak has several healthy components, which come from the vegetables. The peppers, onions and mushrooms are loaded with fiber and numerous vitamins and minerals! This skillet does contain a decent amount of fat, however everyone has different dietary needs and for some, this may not matter as much as it does for others!
How Do I Cut the Steak?
Cut the steak against the grain. Look closely at your meat and you will see small lines that run parallel to each other (these are muscle fibers). Do not cut in the same direction as these lines, instead cut perpendicular to them. Cut the steak about ⅛ to ¼ inch thickeness and about 1.5 inches long.
How to Make A Juicy and Tender Steak?
The cut of steak will affect how tender it is. Ribeye is typically the most tender, followed by flank and sirloin steak. Select a steak that has plenty of marbeling (fat) and cut against the grain.
