These savory, meaty mushrooms are a perfect alternative for those who prefer a vegetarian or vegan option. So, let’s dive right in!

Serving Size and Cooking Time:

This recipe serves 4 people and can be prepared and cooked within 30-40 minutes. It’s a quick and satisfying meal that will surely impress your fellow campers.


To make these mouthwatering Grilled Portobello Mushroom Burgers, you will need the following ingredients:

– 4 large Portobello mushroom caps

– 4 burger buns (whole wheat, brioche, or gluten-free, depending on preference)

– 4 slices of cheese (cheddar, Swiss, or vegan alternatives)

– 1 red onion, thinly sliced

– 1 large tomato, sliced

– 4 lettuce leaves

– 4 tablespoons of olive oil

– 4 tablespoons of balsamic vinegar

– 4 garlic cloves, minced

– Salt and pepper to taste

Ingredient Alternatives:

Feel free to experiment and customize this recipe according to your taste preferences. Here are a few alternatives you can consider:

– Marinade: Instead of using balsamic vinegar, you can try soy sauce, Worcestershire sauce, or even your favorite barbecue sauce for a different flavor profile.

– Toppings: Get creative with your toppings! Add avocado slices, pickles, roasted bell peppers, or even caramelized onions to enhance the taste and texture of your burger.


1. Start by cleaning the Portobello mushroom caps. Gently wipe them with a damp paper towel to remove any dirt or debris. Avoid rinsing them under water, as mushrooms tend to soak up liquid.

2. In a small bowl, whisk together olive oil, balsamic vinegar, minced garlic, salt, and pepper. This will be the marinade for your Portobello mushrooms.

3. Place the cleaned mushroom caps in a shallow dish and pour the marinade over them. Make sure each mushroom is well coated. Allow them to marinate for at least 15 minutes, flipping them halfway through.

4. While the mushrooms are marinating, prepare your grill. If you’re using a campfire grill, make sure the fire has burned down to hot coals. If you have a portable camping grill, preheat it according to the manufacturer’s instructions.

5. Once the grill is ready, place the marinated mushrooms on it, gill side down. Grill for approximately 4-5 minutes on each side, or until the mushrooms become tender and juicy. Feel free to brush them with any leftover marinade while grilling.

6. When the mushrooms are almost done, toast your burger buns on the grill for a minute or two until they become slightly crispy.

7. Remove the mushrooms from the grill and assemble your burgers. Place a grilled mushroom cap on the bottom half of each bun. Top with a slice of cheese and let it melt slightly from the residual heat.

8. Layer your favorite toppings on the cheese-melted mushroom, such as lettuce, tomato slices, and thinly sliced red onions.

9. Finally, place the top half of the bun on your masterpiece, press it gently together, and voila! Your Grilled Portobello Mushroom Burgers are ready to be enjoyed.

Pros of the Recipe:

– Vegetarian Delight: These burgers are a fantastic vegetarian or vegan alternative to traditional meat patties, providing a rich and meaty flavor.

– Healthier Option: Portobello mushrooms are low in calories and fat, making them a nutritious choice for a camping meal.

– Quick Preparation: With a short marinating time and quick grilling, you can have a delicious meal on the table in no time.

– Customizable: You can experiment with different marinades, toppings, and burger bun choices to cater to your preferences.

Cons of the Recipe:

– Mushroom Size: Portobello mushrooms can vary in size, and finding mushrooms that fit the burger buns perfectly can be a challenge. However, you can always adjust the size of the bun or trim the mushrooms as needed.

– Moisture Content: Mushrooms tend to release moisture while grilling, which can make the burger buns slightly soggy. To prevent this, you can grill the mushrooms for a bit longer or lightly toast the buns to create a barrier.

Side Dish Ideas:

Now that you have your Grilled Portobello Mushroom Burgers ready, let’s add some tasty sides to complete your camping feast. Here are a few side dish ideas that pair well with these burgers:

1. Grilled Corn on the Cob: Wrap individual ears of corn in aluminum foil, and grill them alongside the mushrooms. Serve with a sprinkle of salt and a squeeze of lime.

2. Tangy Coleslaw: Prepare a refreshing coleslaw with shredded cabbage, carrots, and a tangy dressing made with mayonnaise, vinegar, and a touch of honey. It adds a delightful crunch to your meal.

3.Grilled Vegetables: Slice up your favorite veggies like zucchini, bell peppers, and eggplant, toss them in olive oil, salt, and pepper, and grill them until tender and slightly charred. It’s a colorful and healthy addition to your camping spread.

4.Sweet Potato Fries: Cut sweet potatoes into wedges, drizzle them with olive oil, sprinkle with paprika, garlic powder, and salt, and roast them on your grill or in a campfire oven until crispy.
