Portobello Sandwiches with Smokin’ Chipotle BBQ Sauce


I’ve trialed many recipes from the cookbook American Vegan Kitchen, by Tamasin Noyes – the Fettuccine Alfredo was so creamy and the Coconut ‘Bacon’ Bits were sheer genius! But the recipe that I go back to time and time again, from this nouveau bistro meets greasy spoon diner collection, is the Smokin’ BBQ Portobello Sandwiches.

Portobello Sandwiches with Smokin’ Chipotle BBQ Sauce - meaty mushrooms smothered in homemade spicy barbecue sauce. Meat-free vegan, dairy-free, optionally gluten-free meal.I LOVE barbecue sauce, and the ability to make my own at home with such ease, is simply too wonderful.

When I first made and photographed this recipe, I didn’t have any buns, so I actually sauteed some kale, placed it on top of some leftover rice, and finished the dish with the smothered mushrooms. It was so bold, flavorful, and downright barbecue-y.

If you want to make these portobello sandwiches backyard barbecue-style, I see no reason why you couldn’t grill some whole portobellos and then slather them with the Q-sauce. Just don’t skip that barbecue sauce! Both my husband and I loved it.

Speaking of the sauce … it is SPICY! We are a bit heat timid around here. If you have sensitive taste buds, too, I recommend cutting the chipotle amount in half and reducing the chipotle chili powder to 1/2 teaspoon..

Portobello Sandwiches
  1. Heat the oil in a large skillet over medium heat. Add the mushrooms, and season with salt and pepper, to taste. Cook, stirring occasionally, 5 to 7 minutes, or until softened. Turn the heat off and add the barbecue sauce to the mushrooms, stirring to coat.
  2. To serve, spread 1 tablespoon of the mayo on each toasted bun. Spoon the mushroom mixture evenly onto the buns and serve immediately.
Seitan Variation: Use the seitan from the Route 66 Seitan Sandwiches (page 114 in American Vegan Kitchen) in place of the mushrooms. Cut the seitan into ¼ to ½-inch slices and proceed with the recipe.

  1. I would not have even looked at this recipe if it wasn’t for the fact that I wanted to get a barbecue sauce recipe. Luckily I saw about substituting seitan for the mushrooms. Yippe. I can not stand mushrooms. Even the sight of them creep me out. They are awlful to look at. As far as the seitan goes, I figured I would make my own recipe, since I do not have the American Vegan Kitchen book. Unless the library carries it. Don’t know the amount to make. Unless you could give me an idea of how much and even da recipe itself.

    • Hi Jennifer, I don’t eat seitan and would honestly have no idea how much to make! The sauce makes about 1 cup, which will cover 4 to 8 servings, depending on how much you like ot use!
