Ingredients and substitutes

To make the perfect portobello mushroom burger, it’s important to use the right ingredients. Here’s what you’ll need:

  • Portobello mushrooms: Choose big, meaty mushrooms that are firm and free of bruises or soft spots.
  • Olive oil: Brushing the mushrooms with olive oil before grilling helps to keep them moist and prevent sticking.
  • Balsamic vinegar: This adds a tangy flavor to the mushrooms, but you can also use red wine vinegar or lemon juice if you prefer.
  • Garlic: Fresh garlic cloves minced or crushed add a savory flavor to the mushrooms.
  • Salt and pepper: These seasonings add a simple yet essential boost of flavor.
  • As for substitutes, you can experiment with different types of mushroom if you can’t find portobellos, such as shiitake or oyster mushrooms. You can also swap out the balsamic vinegar for another type of acid, like apple cider vinegar or lime juice. And if you don’t have fresh garlic, you can use garlic powder instead.

Selecting the perfect mushrooms

When it comes to selecting the perfect mushroom for your portobello burger, there are a few key things to keep in mind.

  • First and foremost, you want to look for mushrooms that are firm and meaty. Mushrooms that are too soft or squishy won’t hold up as well on the grill.
  • Next, take a close look at the gills on the underside of the mushroom cap. You want to choose mushrooms with gills that are still tightly closed, as this indicates that they are fresh. Mushrooms with open or exposed gills may be past their prime.
  • Finally, size matters. Look for mushrooms that are large enough to make a good burger patty, but not so large that they are unwieldy or difficult to cook evenly. A cap that’s around 4-5 inches in diameter is usually just right.

  • Prep – Prepare the mushrooms by wiping them dry with a paper towel. Then, remove the steam and grills.

  • Marinade – In a bowl, combine all the marinade ingredients and brush each mushroom with the marinade on both sides.
    Pro tip – You can use your hands to marinade on both sides of the mushroom.
  • Grill – Heat a grill on medium-high heat. Place the marinated mushrooms gill-side up on the grill and let cook for about 5-7 minutes before flipping and cooking for an additional 3-5 minutes on the other side.
    Pro tip: Make sure to preheat your grill properly and brush the grates with oil to prevent sticking.

  • Stack – Place the mushrooms on toasted Hamburger buns and serve with desired fixings. I topped mine with burger sauce, butter lettuce, grilled onions, and tomato slices.
    Pro tip – If you want to add some extra flavor, try basting your mushrooms with leftover marinade or a mixture of melted butter and garlic.

Toppings and accompaniments

After you’ve grilled your Portobello mushroom burger to perfection, the fun part begins – toppings and accompaniments! This is where you can really get creative and experiment with different flavors and textures.

  • For a classic burger experience, top your mushroom with lettuce, tomato, onion, and pickles.
  • You can also add cheese, avocado, or even a fried egg for extra indulgence. And if you’re feeling adventurous, try topping your burger with sautéed onions and peppers, or a spicy salsa.
  • Cheeseburger – Top the mushrooms with a slice of cheese for the final 2 minutes on the grill.
  • Double burger – Use grilled portobello mushrooms to make a double burger or double cheeseburger
  • To complement your burger, serve it with some delicious sides. Fresh, crispy fries or tangy coleslaw are always crowd-pleasers. Also, grilled vegetables, like zucchini or corn, make for a healthy and flavorful addition to your meal.

Buns for burgers

Buns can make or break any burger. There are many different varieties of burger buns at the grocery store but make sure to pick one that is super soft at least. Today, I am using brioche burger buns.

Customize your mushroom burger

To truly make your mushroom burger your own, it’s important to get creative with the toppings and condiments. While the classic lettuce, tomato, and cheese combo is always delicious, why not try something new? Here are some ideas to get you started:

  • Add some spice with jalapenos or sriracha mayo.
  • Go for a Mediterranean twist with feta cheese, cucumber, and tzatziki sauce.
  • Experiment with different types of cheese, like blue cheese or brie.
  • Top with avocado and a fried egg for extra decadence.
  • Amp up the umami flavor with sautéed onions and mushrooms

The possibilities are endless! Don’t be afraid to mix and match to find your perfect combination. And if you’re feeling really adventurous, try swapping out the portobello mushroom for a different type of mushroom, like shiitake or oyster.

How do I know when the mushroom is fully cooked?

The mushroom should be tender and juicy, and the center should be cooked through. You can check this by piercing the center with a fork or knife – if it’s soft and easy to penetrate, it’s ready to eat.

Can I use other mushrooms instead of portobello?

Absolutely! While Portobello mushrooms are the most popular choice for burgers, you can use any type of mushroom you like. Just adjust the cooking time as needed for smaller or larger mushrooms.

How do I prevent the burger from falling apart on the grill?

Make sure to oil the grill grates and the mushroom caps to prevent sticking. You can also use toothpicks or skewers to hold the burger together while grilling.

Can I prep the mushrooms in advance?

Yes, you can marinate the mushrooms and prep the toppings in advance to save time. Just make sure to keep the mushrooms in an airtight container in the fridge until you’re ready to grill.

Mushroom burger vs beef burger

As plant-based diets become increasingly popular, mushroom burgers are becoming a more common alternative to traditional beef burgers. But how do the two compare?
While beef burgers are known for their rich flavor and satisfying texture, mushroom burgers offer a unique and earthy taste that can be just as fulfilling.
One of the biggest differences between the two types of burgers is their nutritional content. Beef burgers are high in protein but also high in saturated fat, while mushroom burgers are lower in both protein and fat but offer more fiber and other vitamins. Mushroom burgers are also a great option for those who follow vegetarian or vegan diets.
Another difference is the cooking process. Beef burgers require a specific level of doneness to ensure they are safe to eat, while mushroom burgers can be cooked to your desired level of tenderness without the risk of foodborne illness. Additionally, mushrooms tend to absorb flavors more readily than meat, allowing for a wider range of seasoning options.
Ultimately, whether you prefer a mushroom burger or a beef burger depends on personal taste and dietary preferences. Both can be delicious and satisfying when prepared correctly. So, next time you’re grilling up some burgers, consider giving a mushroom burger a try alongside your traditional beef patty. You may just be surprised at how tasty and satisfying it can be.
