How to make Vegetarian Portobello Philly Cheese Steaks

**scroll all the way down for a full ingredient list and printable directions**

• Get all the ingredients prepped and ready to go. 
• Add the vegetables to a skillet*, then cook for about a minute, then sprinkle on the seasonings. Continue cooking them until they are tender and the onions are translucent. 
  • I recommend getting the large portobello caps for this recipes, and slicing them thin to mock a steak strip, but you could also use baby portobello (cremini) mushrooms. I’ve used both with success.
• Sprinkle flour over the veggies and then stir to coat. Add the veggie broth and soy sauce, then stir to disperse. Turn the heat to medium high and cook for about a minute. The liquid should come up to a quick boil and thicken very quickly. Turn the heat off and remove.
• If you like a crispy roll, toast the rolls for a few minutes, then add the filling and a slice of provolone cheese over the top. Enjoy!

*If you want to add steak steak to the the Portobello Philly Cheese Steaks, cook the steak first and throw the veggies in the skillet when there is about 5 minutes left to cook the steak. Continue with remaining directions. 

Can I use a different cheese in a cheese steak?

If you don’t care for provolone cheese on a vegetarian Philly cheese steak, there are other options that will work. While not traditional, they are delicious!

• Havarti, gouda, or mozzarella cheese would all work wonderfully on a vegetarian portobello philly cheese steak!

Is a Vegetarian Cheese Steak Healthy? 

Healthy is subjective, but I do think it’s a good option depending on your diet. I calculated the nutritional information, but it will be subjective on the rolls you buy, so make sure to calculate with your ingredients if needing the information to be accurate.

Each sandwich contains about 394 calories, 9 grams fat, 4 grams saturated fat, 62 grams carbohydrates, 6 grams fiber, 9 grams sugar, and 19 grams protein. They also contain over 100% of your daily Vitamin C!

• To make it lower carb (South Beach Diet, KETO): Use a cloud bread or low carb roll. The roll could also be left out entirely and the filling could be served over cauliflower rice or a salad. 
• To make it Gluten Free: Use a gluten free flour in the saute step like almond or coconut flour. Both should work fine. Instead of traditional soy sauce use tamari which is a gluten free soy sauce. Use a gluten free roll for the sandwich or leave the roll out entirely. 

What to serve with Vegetarian Portobello Philly Cheese Steaks:

• Simple Buffalo Potato Wedges are easy to make and ultra delicious. 
• Air Fryer Roasted Broccoli is healthy, takes only a few minutes, and is the perfect side dish. 
• Air Fryer Roasted Asparagus will be your favorite way to cook asparagus from now on! With only 2 ingredients and taking a fraction of the typical time, they make an easy nutritious side dish!
• Air Fryer Crispy Parmesan Brussels Sprouts are going to be your new go-to side dish. Only a handful of ingredients and only 132 calories per serving!
• Roasted Red Pepper Soup is the perfect comfort food without any guilt! Make it in the Instant Pot, Slow Cooker, or on the stove top!
