More and more I crave meatless recipes. Perhaps I was a vegetarian in a former life? Maybe. All I know is that I love vegetables, especially mushrooms.
If you haven’t had a portobello burger yet, this is your time to go for it. I am completely, 100% on team portobello burger. At first I was skeptical, sure, who wouldn’t be? Mushrooms masquerading as a beef patty, I mean yeah, I was definitely leery. But over the last year, I’ve been ever so slowly working portobellos into recipes that typically call for some sort of meat protein. I grilled them for quesadillas and panfried them for fajitas, and I use baby portobellos in just about all the recipes calling for mushrooms. I’m also working on another recipe that I hope to share before the summer is over. But today, it’s all about this grilled teriyaki portobello burger.
Thick, meaty mushrooms are slathered in homemade teriyaki sauce and grilled until tender and caramelized. Then I top each burger with a slice of gouda, and once it melts into cheesy bliss, I nestled the burger into butter lettuce leaves and topped it with lots of grilled red onion, a slice of grilled pineapple and fresh sprouts. I even went a step further and made a honey wasabi mayo to tie this delicious burger together.
It’s a little sweet and a little spicy. Just how I like it
To make these grilled teriyaki portobello burgers, you will need: 4 portobellos, teriyaki sauce, sliced onion and fresh pineapple, gouda (slices or freshly grated), butter lettuce, mayonnaise (homemade or store-bought), garlic, honey and wasabi paste.
When I was at my grocery store I had two options for wasabi: a pre-made paste with a slew of iffy ingredients or wasabi powder that had 3 ingredients that I’ve heard of and could pronounce, so I went with the latter. To make wasabi paste from the powder, just combine a little of the wasabi powder with a little water until it makes a thick paste.
In a small bowl, combine 1/2 cup mayo with 1 small clove grated garlic and a 1 teaspoon honey.
Then only add in a pea-size amount of the wasabi paste at a time until you get the flavor you want. A little wasabi goes a long way, so only add a little at time and whisk and taste as you go.
Preheat your outdoor grill (or grill pan) to medium-high heat or about 400° to 425° Fahrenheit. Clean any dirt off of the portobello mushrooms and brush the underneath side with teriyaki sauce and spritz with an olive oil mister. Lightly mist both sides of the pineapple and onion slices with olive oil as well. This helps to keep them from sticking when grilling
Once your grill is hot, place the pineapple, onions and portobellos on the grill grates. Brush the portobello tops generously with teriyaki sauce. Close your grill lid and grill for 8 to 10 minutes or until good grill marks form.
Then carefully turn the portobello burgers, pineapple and onion slices. Close the grill and continue grilling for 3 to 4 minutes more.
Open the grill and top each burger with a slice of gouda cheese. Go ahead and close the lid if the cheese needs help melting, it should only take a minute or two. Remove the burgers, grilled pineapple and red onion.
Now it’s time to build these burgers!
You should smell this deliciousness!
Divide a few butter lettuce leaves onto four plates, add a dollop of the honey wasabi mayo and top with a grilled teriyaki portobello burger, slices of grilled red onion, pineapple and more teriyaki sauce if desired. Garnish with sprouts and a sprinkle of sesame seeds.
