Portobello Mushroom Philly Cheesesteak

It tastes just like a Philly cheesesteak - just without the "steak!"

I don’t know about you, but I’m completely and totally blown away by this Portobello mushroom Philly cheesesteak recipe. Seriously – take a look at how beautiful that sandwich is! If I was looking at that sub from afar, I would never guess it was a vegetarian recipe. Even after taking a bite, I didn’t miss the meat.

You might have your doubts – after all, our Portobello Mushroom Philly Cheesesteak has neither cheese nor steak. Those kind of seem like important ingredients – especially since they’re in the title of the sandwich. But, we wanted to take an iconic carnivore sandwich and turn it into a Meatless Monday celebration. After making myself one of these, I have to say: this recipe absolutely nailed it.

Why This Recipe Works

There are a few key factors to why this recipe works. The first is the use of Worcestershire and soy sauces – we’ll get to why that’s so important in a minute. The second is the combination of vegetables. You see, we’re not just tossing a few Portobello mushrooms onto a bun and calling it good. We’re combining a bunch of nutrient-dense vegetables to really create something special.

Every vegetable we’ve chosen brings a unique flavor profile to the sandwich. The mushrooms are meaty, the red onion is sweet, and the garlic is pungent. The combination of red and green bell peppers brings a grassy-but-fruity flavor to the table. Finally, the spinach and the parsley bring herbaceous flavors that complement the other vegetables.

And then comes the sauce – I promised I’d get back to why it’s so important! Both Worcestershire and soy sauces are filled with savory (or, umami) flavors. They deepen the meaty flavor of the mushrooms and work hard to meld all of the vegetable flavors. When it all comes together, it will almost taste cheesy – just like a Philly cheesesteak.

There you have it – the perfect meatless Portobello Mushroom Philly Cheesesteak. It’s a great choice for a backyard barbecue or dinner party, but it also works as a filling lunch. I’m not sure that I can stare at that picture any longer without hitting the kitchen and making one for myself!

Ingredients

  • 2 tablespoons olive oil

  • 1 green bell pepper small, sliced thin
  • 1 red bell pepper small, sliced thin
  • 1 red onion sliced thin
  • 2 garlic cloves
  • 2 cups baby spinach
  • 1/4 cup parsley fresh, chopped

  • In a large skillet, heat the olive oil. Once hot, add the mushrooms, bell peppers, onion, and garlic. Cook until the vegetables are very soft, about 8 to 10 minutes.

  1. Looks Excellent!

    I’m making for dinner tonight, but 1/4 c black pepper? I’m assuming that’s a typo. That much black pepper can get s-p-i-c-y SPICY!

    1. Gloria, We don’t promote brands but I would recommended looking at the ingredients to ensure there is no “enriched” flour or “refined” sugar.

  2. This looks great and I cant wait to try it! FYI. Worcestershire sauce is not vegetarian. It is made with anchovies. There are vegan versions available. You may want to specify that in your recipes for those who are not aware and want a truly meatless meal. Thank you again for this recipe. It looks awesome!
