Expert Technique Tips for Grilling Portobello Mushroom Burgers
When grilling portobello mushrooms, it's important to avoid overcooking them as they can become tough and lose their juicy texture. Keep a close eye on them and remember to frequently baste with the marinade to keep them moist and flavorful. Additionally, grilling the buns until they are toasted adds a nice crunch and can prevent them from becoming soggy from the mushroom's juices.
Time-Saving Tips for Making Grilled Portobello Mushroom Burgers
Marinate efficiently: Combine all marinade ingredients in a resealable plastic bag and add the mushrooms. Seal the bag and massage the marinade into the mushrooms, ensuring they are evenly coated. This method saves time and reduces the need for extra dishes.
Prep in advance: Clean and marinate the mushrooms the night before, allowing them to absorb the flavors overnight. This not only saves time on the day of cooking but also enhances the depth of flavor in the mushrooms.
Grill in batches: If you're making multiple servings, grill the mushrooms in batches to ensure even cooking and to prevent overcrowding on the grill, which can lead to uneven cooking.
Use a grill pan: If an outdoor grill isn't available, use a grill pan on the stovetop for convenience and quick cleanup.
Organize ingredients: Before starting, organize all the ingredients and utensils needed for the recipe. This will streamline the cooking process and minimize the risk of overlooking any components.

Essential Tools for Crafting the Perfect Grilled Portobello Burger
Grill or indoor grill pan: A grill or indoor grill pan is essential for grilling the portobello mushroom caps to perfection. It provides the smoky flavor and charred marks that enhance the overall taste and appearance of the burger.
Large bowl: A large bowl is used for marinating the portobello mushroom caps in the balsamic vinegar, soy sauce, olive oil, and seasonings. It allows for easy tossing and coating of the mushrooms with the marinade.
Whisk: A whisk is necessary for combining the balsamic vinegar, soy sauce, olive oil, rosemary, and steak seasoning to create the marinade for the portobello mushrooms.
Grill brush or oil spray: A grill brush or oil spray is used to grease the grill grate or indoor grill pan to prevent the mushrooms from sticking during the grilling process.
Spoon: A spoon is used to toss and evenly coat the portobello mushroom caps with the marinade in the large bowl. It helps in distributing the marinade evenly over the mushrooms.
Cheese grater: A cheese grater is used to grate the reduced-fat Swiss cheese, which is then placed on top of the grilled portobello mushrooms to melt and add a delicious cheesy flavor to the burger.
Knife: A knife is essential for slicing the red onions, tomatoes, and avocado for assembling the grilled portobello mushroom burgers.
Grill tongs: Grill tongs are used for flipping the portobello mushroom caps and grilling the onions on the grill. They provide a secure grip and control when handling the ingredients on the grill.
Toaster or grill for buns: A toaster or grill is used to toast the whole wheat low-calorie buns, adding a crispy texture and warmth to the burger buns before assembling the burgers.
Storing and Freezing Grilled Portobello Mushroom Burgers
- To store leftover grilled portobello mushroom burgers, wrap each burger tightly in plastic wrap or aluminum foil and place them in an airtight container. They can be stored in the refrigerator for up to 3-4 days.
- If you want to freeze the burgers, wrap each one individually in plastic wrap or aluminum foil, making sure to remove as much air as possible. Then, place the wrapped burgers in a freezer-safe container or a resealable freezer bag. Label the container or bag with the date and contents.
- Frozen grilled portobello mushroom burgers can be stored in the freezer for up to 2-3 months. When you're ready to enjoy a frozen burger, remove it from the freezer and let it thaw in the refrigerator overnight.
- To reheat a refrigerated or thawed burger, you can either microwave it for a minute or two until heated through or place it in a preheated oven at 350°F (175°C) for about 10 minutes. If the bun is stored separately, toast it lightly before reassembling the burger.
- For best results, store the grilled portobello mushrooms, cheese, onions, and buns separately from the fresh toppings like tomato, avocado, and spinach. This will help prevent the buns from getting soggy and the fresh ingredients from wilting or becoming mushy.
How To Reheat Leftover Portobello Mushroom Burgers
The best way to reheat a leftover grilled portobello mushroom burger is to separate the components and reheat them individually. This will ensure that each part of the burger is heated through without becoming soggy or overcooked.
Remove the portobello mushroom cap, cheese, onions, tomato, and avocado from the bun. Set aside the spinach, as it doesn't need to be reheated.
Preheat your oven to 350°F (175°C). Place the portobello mushroom cap on a baking sheet and top it with the cheese. Bake for 5-7 minutes or until the mushroom is heated through and the cheese is melted.
While the mushroom is heating, wrap the bun in aluminum foil and place it in the oven for the last 2-3 minutes of the mushroom's heating time. This will warm the bun without drying it out.
In a skillet over medium heat, add a small amount of olive oil and reheat the grilled onions for 1-2 minutes or until they are warmed through.
Once all the components are heated, reassemble your portobello mushroom burger. Place the spinach on the bottom bun, followed by the heated mushroom with cheese, grilled onions, tomato, and avocado. Top with the other half of the bun.
Alternatively, you can reheat the entire assembled burger in the microwave for 30-60 seconds, depending on your microwave's power. However, this method may result in a softer bun and slightly overcooked toppings.
If you have access to a panini press or a grill pan, you can reheat the assembled burger for 2-3 minutes, pressing down gently to warm the ingredients and create a crispy exterior on the bun.

Is This Grilled Portobello Mushroom Burger Healthy?
The grilled portobello mushroom burger recipe is a healthier alternative to traditional beef burgers. The use of portobello mushrooms as the main ingredient provides a good source of fiber, vitamins, and minerals while being low in calories and fat. The whole wheat buns and the addition of vegetables like spinach, tomato, and avocado further enhance the nutritional value of the burger.
However, there are a few aspects of the recipe that could be improved to make it even healthier:
- The recipe calls for reduced-fat Swiss cheese, which still contains saturated fat and sodium. Opting for a lower-fat cheese or omitting it altogether would further reduce the fat content.
- The marinade contains soy sauce, which is high in sodium. Using a low-sodium soy sauce or replacing it with a healthier alternative like coconut aminos would help reduce the overall sodium content.
- While the recipe uses whole wheat buns, they are still processed grains. Replacing them with lettuce wraps or a whole grain option like a sprouted grain bun would provide more nutrients and fiber.
To make this recipe even healthier, consider the following suggestions:
- Add more vegetables to the burger, such as grilled zucchini, bell peppers, or caramelized onions, to increase the fiber and nutrient content
- Use a homemade avocado spread instead of sliced avocado to evenly distribute the healthy fats and make the burger easier to eat
- Experiment with different herbs and spices in the marinade, such as garlic, thyme, or smoked paprika, to add more flavor without relying on salt
- Serve the burger with a side salad or roasted vegetables to make it a well-rounded, nutrient-dense meal
