I was browsing through the produce section of Costco yesterday when I came across some beautiful organic portobello mushrooms.

With the upcoming July 4th holiday coming up, I grabbed them thinking I’d make some simple mushroom burgers.

Then as I was at our supermarket I saw some soft whole wheat tortillas. When I got into the kitchen I was inspired to try my hand at making vegan bao buns!

These buns are somewhat of a cross between a Mexican taco and a Korean bao bun. A true authentic bao bun is a puffy soft white flour type of bun.

These are made using a soft whole wheat tortilla that is store bought. Hence, why this recipe is so quick, easy, and the perfect vegan prep meal!

We had this food cart court in our downtown that was open during lunch. There were some amazingly delicious carts, and one of my favorites was a Korean cart that served up the most amazing mushroom bao buns!

Unfortunately, the food court closed up shop some years ago, and I haven’t been able to get my hands on those buns!

So, while I had planned to make burgers, the soft whole wheat tortillas reminded me of a healthy bao bun, which motivated me to try something different!

I thinly sliced the mushrooms, doused them in soy sauce, sriracha, and sweet chili sauce.

Then cooked them stove-top, sandwiched them between buns with some quick pickled onions, and the result was a simple portobello bao bun that makes for an easy weeknight dinner!

Top Tips for Making the Perfect Vegan Bao Buns with Portobello Mushrooms

• Thoroughly wash mushrooms before slicing. Use a wet paper towel or soft brush to gently remove any dirt.
• Slice the portobellos into thin long strips.
• Slice onions into thin long strips.
• After mushrooms are done cooking. Remove from pan, and add any extra marinade from the marinating bowl to the pan. Simmer on low to thicken. Use the sauce to drizzle on top of the buns for added flavor!

Variations

Can’t Find Whole Wheat Buns-If you can’t find the soft whole wheat tortilla buns in your grocery store, you can use a different type of tortilla, such as a corn tortilla. Although, it will take on more of a taco feel than a bun. You can also find authentic bao buns in many Asian grocery stores. Or you can make your own bao bun.

Marinade-Add your favorite Asian seasoning to the marinade. Try teriyaki sauce, or hoisin sauce. If you don’t have fresh ginger use dried.

How to Keep and Serve

Serving Suggestions

Serve with a light side salad of spinach, tomatoes, and pickled onion. Use your leftovers from your bun fillings.

You could also serve this with a light soup like this Vegan Miso Soup by From My Bowl.

Store and Keep

Store any leftovers in the refrigerator in an air tight container for 3-4 days. I store the mushrooms, onions, and buns in their own containers, and assemble when I’m ready to eat.
