What Goes Into a Mushroom Burger?
Where do you begin making a Grilled Portobello Mushroom Burger? With the most important ingredient: Portobello mushrooms!
When shopping for mushrooms, consider spending a little extra money. The mushrooms will be the main ingredient in your burger, so you’ll want as high-quality Portobello mushrooms as possible. Also, look for larger Portobello mushrooms, as they will shrink just slightly during the cooking process.
While at the store, grab a few items for the marinade, if you don’t already have these in your pantry. This includes balsamic vinaigrette, extra virgin olive oil, minced garlic, a lemon, salt and pepper, dried basil, and dried oregano.
You’ll also want to consider purchasing the toppings for your Grilled Portobello Mushroom Burgers! This can include sliced Swiss cheese, Brioche hamburger buns, tomatoes, avocado, lettuce, onion, and any other toppings you enjoy on your burgers.
The final ingredients you’ll need are for the optional Burger Sauce. This creamy sauce has a slight kick to it that will make your burger taste amazing!
These ingredients include mayonnaise, stone ground mustard, ketchup, brown sugar, apple cider vinegar, Worcestershire sauce, onion powder, and garlic powder.
Make Your Grilled Portobello Mushroom Burger!
Now you’re ready to make those burgers!
Start the fire in the pit at the campsite and add a grill grate. Or preheat the portable grill, if you’ve chosen to bring one along.
While the fire gets nice and hot, mix 2 tablespoons balsamic vinaigrette, 1 tablespoon extra virgin olive oil, 1 tsp minced garlic, the juice of 1 lemon, 1 teaspoon basil, 1 teaspoon oregano, and salt and pepper to taste to make the vinaigrette.
Next, remove the stems and gills from the Portobello mushrooms.
Gently clean the tops of the caps. Set the mushroom caps on a plate and brush the insides and outsides of the mushrooms with the marinade. Allow them to sit for 15-20 minutes so the marinade can sink in.
While you wait for these to soak in the marinade, you can cut or prepare the burger toppings. You can also mix the creamy Burger Sauce if you’ve decided to add that to the menu.
To make the Burger Sauce, combine 1/2 cup mayonnaise, 2 tablespoons stone ground mustard, 1 tablespoon ketchup, 1 tablespoon brown sugar, 2 teaspoons apple cider vinegar, 1 teaspoon Worcestershire sauce, 1/2 teaspoon black pepper, 1/2 teaspoon onion powder, and 3/4 teaspoon garlic powder. Set aside until ready to serve.
When the fire or grill is heated, cover it with a sheet of aluminum foil. Next, add the Portobello mushrooms.
Cook for 5-7 minutes on each side.
During the last minute of cooking, add 1 slice of cheese to each burger.
Now you’re ready to serve your Grilled Portobello Mushroom Burgers!
Add your desired toppings and the Burger Sauce.
Mix Up Your Burger
What are a few ways you can mix up your Grilled Portobello Mushroom Burgers?
Try grilling the onion slices, as well. Cooked onions can change the flavor of a burger entirely!
Also consider toasting the buns for a few minutes, until they’re slightly browned. A warm bun always compliments a fantastic-tasting burger!
Not interested in the mess of using a marinade? Simply lightly coat each of the Portobello mushrooms with extra virgin olive oil, then salt and pepper before popping them on the grill. They’ll taste just as great!
