    Vegan Portobello French Dip

    Published: Jul 26, 2017 · Modified: Sep 15, 2020 by Chuck Underwood · 19 Comments

    For all you sandwich lovers out there, here is a Vegan Portobello French Dip I made the other night that is WAY better than any fast food you remember.

    Slather on a little spicy brown mustard and you've got yourself one hearty sandwich!

    vegan portobello french dip

    Sandwiches can be hard sometimes, I know, because other than a veggie sandwich, or some processed soy junk you find in the grocery store, what are you going to put on them?

    Sure, you can always make a good BBQ Sandwich with soy curls, or toss together some quick mock Chickpea Tuna, but what else?  What about something a little more....meatier....

    Try mushrooms.

    Portobello mushrooms have a chewy, beefy texture that can easily replace meat on any sandwich.  Add some caramelized onions, sliced peppers, and a tangy Au Jus for dipping and NOW you got a sandwich!

    As for the bun.... and I ALWAYS get asked about the bun.....

    It can be REALLY hard to find bread or buns that don't contain a million preservatives or oil.  But what I do is always look for the one that has the fewest number of ingredients and the least amount of calories from fat.  Unfortunately, these usually do NOT come with the lowest price tag.

    Dave's Killer Bread is always a good option for bread, and so is the Ezekiel brand - but there really isn't a lot of options unless you make it yourself from scratch.

    But if nothing else, these French Dips would ALSO go great topped on a Baked Potato....just stuff the filling inside a big baker and pour on the Au Jus!

    Now you got your meat AND potatoes all in one meal 🙂

    Enjoy.

    Vegan Portobello French Dip

    Take a LARGE sweet onion (vidalia, walla walla, etc) and slice it into thin rings.  Also, slice up 2 Bell Peppers and toss all of these veggies into a skillet.

    Sprinkle with a dash of salt - which will help draw out the moisture.

    Cook over medium heat until they begin to soften.  I did not need ANY liquid as my Walla Walla Sweet released a ton of its own.  Just keep stirring so they don't stick or burn.

    Meanwhile, rinse and dry 4 large Portobello Caps (I bought two 8oz packages) and then slice them into ¼" thick slices.

    When the onions are almost done....add a few teaspoons of chopped garlic and stir well to mix.

    Add the mushrooms to the skillet, and slowly sauté them until they begin to release their liquid.  Use the 2 Tbs of Veggie Broth if needed to prevent sticking  (or soy sauce, water, etc - just no oil).  Season them with the Italian seasoning.

    In a small bowl whisk the veggie broth, soy sauce, vegan Worcestershire, molasses, liquid smoke, and cornstarch together until smooth.

    Note:  Maple Syrup will work in place of the molasses and smoked paprika in place of the liquid smoke.  Also, Vegan Worcestershire is available in many stores and does NOT contain anchovies.  Check the label as it may not say vegan on the front.   

    Once the liquid has just about evaporated from the mushrooms, slowly pour in the bowl of Au Jus and stir to mix.   Season with salt and pepper to taste.

    Let simmer a little bit in the Au Jus until the sauce thickens.

    Serve with Potato Salad or French Fries. 

    Hope you enjoy the sandwiches and thanks for all the comments!

      Wow! This was better than I expected. My husband loved it so it’s a keeper. He’s trying to transition partially. I’ll accept that as progress.

      Wow! This was an awesome recipe. We loved it. The sauce tasted so good, we might try to use it to make an onion soup. Thanks for sharing.

      I am a new vegan and challenged by being gluten free and soy free. This recipe looks really good and I am anxious to try this. Thanks for giving these great ideas.

      This is delicious. I feel like I’m eating gourmet food. Just love it.
      I made a few substitutions or deletions because I’m SOS free. But it all worked out. Best sandwich ever.

      This was delicious! We sliced a sourdough round loaf from Whole Foods.

      Recipe is very good even though I had to make substitutions due to food sensitivities (no peppers but shredded carrots, mushroom broth instead of veggie broth and maple syrup instead of molasses, which I didn’t have). Chuck’s recipes are so great for me because they can accommodate and still be awesome. I can only imagine how authentic the accurate recipe tastes but my accommodations still made a delightful meal that will be repeated. I look to get some molasses given the description it adds to recipes. I think Chuck uses it in some other recipes. I will be ready.

      I made this the other day for the first time. WOW! With the leftovers, I mixed them with some other chopped veggies and an oil-free pasta sauce and put it over a homemade vegan pasta. Turned out great. I'll definitely be making this again. Thank you, Chuck.
