Portobello Cheesesteaks

Portobello Cheesesteak on a plate with steak fries.

This is one vegetarian dish where you won’t miss the meat. And it’s a simple dish requiring only a few ingredients. A fresh sub stuffed to the brim with sautéed portobellos, red pepper, and onions, covered with Provolone cheese and toasted. Just a little oil/butter, soy sauce, Worcestershire, thyme, provide all the flavor necessary. The whole family will look forward to these Portobello Cheesesteaks.

 

When I first started typing this post, I titled it “Portobello Cheesecake” and I almost didn’t catch my mistake. How funny would that have been? Although…., it has me thinking. Maybe a savory Portobello Cheesecake isn’t such a bad idea. I’ll have to think about that one.

Cheesesteaks (and cheesecakes :)) are a favorite of mine. I don’t now nor have I ever lived in Philly, so my definition of a cheesesteak is a liberal one. I will say I prefer thinly sliced Provolone cheese on my cheesesteak over the more traditional cheese sauce. But there’s no steak in these Portobello Cheesesteaks so we’re no where near traditional anyways.

I always prefer to remove the gills when cooking Portobello mushrooms. They tend to discolor whatever they come in contact with and they really don’t add anything to the flavor. Just scoop them out with a spoon and ray good riddance to them.

The sautéed Portobello slices are fabulously meaty and you won’t miss the steak in these vegetarian cheesesteaks. Well, maybe a little. But you for sure won’t miss the calories. And don’t worry about not being full after. This is one hearty meal.

  1. I just made these and they were one of the. easiest and most delicious vegetarian dinners I have had! I made meaty cheesesteaks for the others in my family, and I have to admit, I feel like I got the better meal for once! Thanks! 🙂

    1. Christin Mahrlig

      Yay! I’m so glad you liked them. And I tend to like them better than a meat version myself 🙂

  2. Irina @ wandercrush

    Oooh, this is such a great idea. After my first month in Europe, the first thing I ordered upon landing in the Philadelphia airport was a huge Philly Cheesesteak. This is a much healthier version that I should try soon for old times’ sake.
    Looking forward to your portobello cheesecake post 😉

    Portabella’s are the perfect substitute for meat in vegetarian meals! The variation sounds absolutely mouthwatering, I can’t wait to try it!! Thanks for sharing…

    How funny that I think that it read “Portobello Cheesecake” when I clicked the link as well! I though it would be a bit weird with portobellos haha. But oh boy, when I saw this sandwich I knew that this was going to be my dinner soon. Now, this is the kind of sandwich I LOVE. Great idea, Kristin 🙂

  5. Amy @ Elephant Eats

    What a great idea to sub portobello for the meat! I went to college and part of grad school in Philly so I know my cheesesteaks, and I’d happily eat this one 🙂

  6. Ha! When I first quickly read the title I actually thought it said cheesecakes! But seriously though these sound awesome – I love meatless meals like this where you really don’t miss the meat. And I love how ooey gooey cheesy these look!

    Oh god, this sounds amazing. I’d really like to try this with some grilled halloumi and toasted bread… That would be heaven.

  8. I’m a huge mushroom lover, and I know I would prefer this to cheesesteak any day. Great idea, Christin!

  9. You had me at portobello! YUM! While I do love myself a good regular cheesesteak, this sandwich looks amazing. I don’t think I would miss the meat a bit!

      Portobellos are great aren’t they? It’s nice to be able to have a meaty sandwich without the meat! Have a great day!

    Have never tried a meatless version of cheesesteaks. The portobello cheesesteaks sound incredibly wonderful veg version.

  11. What a great meatless take on the cheesesteak sandwich! I love Portobello mushrooms and would definitely not miss the meat here 🙂 The flavors sound fantastic and I think even my meat-loving hubby would enjoy these a lot. Pinning and thanks for sharing Christin!

  12. Love this idea, thanks! I did a savory cheesecake when I had a batch of cream cheese made from carabao milk which had a bit more funk than usual. Mushrooms and smoked oysters. It was lovely.
    About to give these sandwiches a go. Tempted to use the traditional “fake cheese” since for some reason there is some in the pantry (WHO PUT THIS HERE?!!), but the Provolone sounds just fine.

      A savory cheesecake with mushrooms and smoked oysters sounds great. I love smoked oysters, but don’t come across too many other people who do. LOL on the fake cheese in the pantry!

    I love cheesesteaks and love this meatless version of it. Portobello mushrooms are so meaty that you wouldn’t even miss the meat. Great recipe Christin!

    1. Christin Mahrlig

      That is true Anne! Portobello mushrooms are one of the few vegetarian foods that don’t leave me feeling like I rather would have had meat. 🙂
