Spicy Roasted Portobello Sandwiches with Bell Peppers and Camembert

I’m eating these crazy-good, over-the-top sandwiches at least once per week.

And even if you vowed to eat healthier this year, with salads and such, you can still eat these because they have salad on them.

So that counts, right?

The whole time AJ and I were eating them, we kept saying over and over again, in between scarfing down huge bites of mushroom, cheese, and bread, that these were some of the best sandwiches ever.

They start with roasted portobello mushrooms in a spicy sauce made from chili garlic paste and soy sauce – the perfect combo of spicy and umami flavors.

Then, there are the roasted bell peppers, which go perfectly with the savory mushrooms.

And then there is a little bit of greens for that balance of freshness. I used baby kale, but peppery arugula would also be fantastic.

And it doesn’t stop there. Ready for this?

What ties all this together is a layer of gooey, indulgent cheese that gets melty and toasty in the oven right before you make your sandwiches. Divine.

And the finishing touch – brushing any leftover sauce on the other piece of ciabatta bread, smashing it all together into a sandwich, and then eating until your face is covered in spicy sauce and your belly is nice and full.

Have fun, get messy, and ignore those resolutions for just a little longer. Make the recipe below!

Description

Looking for a meaty, yet vegetarian, sandwich? Make these spicy roasted portobello mushroom sandwiches with cheese and bell peppers.


Scale

Ingredients

For the Sauce:

  • 1/4 cup soy sauce
  • 2 tablespoons chili garlic sauce
  • 1 tablespoon sesame oil
  • 1 tablespoon barbecue sauce
  • 1 teaspoon Dijon mustard
  • 3 tablespoons olive oil

For the Sandwiches:

  • 5 large portobello mushrooms
  • 1 red bell pepper
  • 8 ounces Camembert cheese
  • 2 cups baby kale leaves
  • 1 loaf ciabatta bread, or 4 small ciabatta buns

Instructions

To Cook the Vegetables:

  1. Combine all of the sauce ingredients in a medium bowl and mix together with a small whisk or fork.
  2. Rinse the portobello mushrooms, then use a spoon to gently remove the gills. Cut into 1/2-inch slices and place in a bowl. Add about 2/3 of the sauce to the mushrooms and use a spoon to gently toss so that they are evenly covered. Let sit for about 30 minutes while you roast the bell peppers.
  3. Turn your oven to broil and place the bell pepper about 1-inch away from the broiler. Cook, turning every couple minutes, until blackened in spots all over. Broiler strength can vary, so the time this takes will vary, as well. Mine took about 10 minutes total, but keep a close eye on yours.
  4. When the bell pepper is done cooking, transfer it to a cutting board and let cool. Once you are able to handle it, cut off the top and drain the liquid and remove the seeds. Peel off the skin as best you can, then slice into 1/4-inch strips.
  5. While the pepper is cooling, turn the oven to 350ºF. Grease a baking sheet, then spread the marinated mushrooms out evenly on the sheet. Roast for about 25-30 minutes, tossing halfway through, until soft. Remove from the oven but leave the oven on.

To Assemble:

  1. While the mushrooms cook, slice the ciabatta bread into 4 sections, then cut each section in half through the middle to make the sandwich bread.
  2. Spread half of the bread slices (one per sandwich) with some of the camembert cheese. Place in the 350ºF oven on a baking sheet for about 5 minutes, until the cheese is melted and the bread is a bit toasty.
  3. Brush the plain bread slices with the leftover spicy sauce. Layer the kale, mushrooms, and bell pepper on top of the cheesy bread. Top with the sauced slices of bread. Enjoy!

Relax – Start the Diet Next Week

It’s fine to have a cheat day each week! And I won’t tell on you if you decide to have more than one cheat day each week…

Tell yourself that you don’t really need to eat just green salads and green smoothies and whole grains for the new year.

Stock up on mushrooms and good crusty bread instead, because these vegetarian delights will be your new indulgence.

At least, I know they’ll be mine!

  1. I just made these and let me tell you.. Man they are GOOD! Even my carnivore husband ate one and he found them delicious. This was a hit in many ways.. It’s easy to do, it’s fresh, it’s light but also so satisfying.. I just love how tasty they are.. I also added eggplant to mine and man o man.. What a hit.. Needles to say, these are going to be a regular in my kitchen from now on.
