Ultimate Mushroom Burger

I remember the first time I truly appreciated the humble mushroom. It wasn’t in a cream of mushroom soup, nor nestled amongst a stir-fry. It was at a backyard barbecue, where my uncle, a man notorious for his simple-yet-satisfying grilling prowess, presented a burger unlike any I’d seen before. Towering over the standard patties, nestled between toasted buns, were portobello mushrooms, glistening with olive oil and promising an earthy, savory bite that elevated the entire experience. That single burger sparked a lifelong love of experimenting with mushrooms, a journey culminating in this Ultimate Mushroom Burger, a tribute to that unforgettable meal.

Ingredients

3 lbs certified Angus ground chuck
Salt and pepper
6 large portobello mushrooms, cleaned and stemmed
Olive oil, as needed
3 tablespoons butter
8 cups sliced mushrooms (cremini, shiitake, or your favorite blend)
¼ cup sherry wine
⅓ lb grated smoked Gouda cheese
Burger buns of your choice

Equipment Needed

Grill
Medium fry pan
Tongs
Basting brush
Cutting board
Sharp knife

Instructions

Begin by preparing the ground chuck. Season generously with salt and pepper. Divide the seasoned meat into six equal portions, approximately 8 ounces (225 g) each. Gently form each portion into a patty, being careful not to overwork the meat. Overworking will result in a tough burger.
Preheat your grill to medium-high heat. While the grill is heating, prepare the portobello mushrooms. Use a damp cloth or paper towel to gently clean the mushrooms, removing any dirt or debris. Carefully remove the stems.
Brush both sides of each portobello mushroom cap with olive oil. Season lightly with salt and pepper.
Place the portobello mushrooms on the preheated grill, gill-side up. Grill for approximately 10 minutes per side, or until they are tender and have grill marks. They should release some of their moisture and become slightly pliable.
While the mushrooms are grilling, place the ground chuck patties on the grill. Grill to your desired doneness. For medium-rare, cook for about 4-5 minutes per side. For medium, cook for about 6-7 minutes per side. Use a meat thermometer to ensure accuracy. The USDA recommends an internal temperature of 160°F (71°C) for ground beef.
As the burgers are grilling, prepare the sautéed mushrooms. In a medium fry pan, melt the butter over medium heat.
Add the 8 cups of sliced mushrooms to the melted butter. Sauté, stirring occasionally, until the mushrooms are softened and have released their moisture, about 8-10 minutes.
Pour in the sherry wine and continue to cook for another 2-3 minutes, allowing the wine to reduce slightly and the alcohol to evaporate. The sherry adds a depth of flavor that complements the earthy mushrooms beautifully.
To assemble the burgers, place the grilled portobello mushroom caps on a clean surface (or on the bottom bun, if using).
Top each portobello with a grilled ground chuck patty.
Spoon the sautéed mushroom mixture over the burger patties.
Generously sprinkle the grated smoked Gouda cheese over the mushroom mixture.
Carefully move the assembled burgers to the top shelf of the grill, or a cooler part of the grill, and close the lid. Allow the cheese to soften and slightly melt, about 2-3 minutes. Alternatively, you can broil the burgers in the oven for 1-2 minutes, watching carefully to prevent burning.
Remove the burgers from the grill and serve immediately on your favorite burger buns, if desired.

Expert Tips & Tricks

Don’t overcrowd the pan when sautéing the mushrooms. Overcrowding will cause the mushrooms to steam instead of brown. Cook in batches if necessary.
For a deeper, richer flavor, use a combination of different mushroom varieties for the sautéed mushroom mixture. Cremini, shiitake, and oyster mushrooms work well together.
If you don’t have sherry wine, you can substitute dry white wine or chicken broth. The flavor will be slightly different, but still delicious.
To prevent the burgers from sticking to the grill, make sure the grill grates are clean and well-oiled. You can use a grill brush to clean the grates and then brush them with olive oil.
For extra flavor, add some minced garlic or shallots to the sautéed mushroom mixture.

Serving & Storage Suggestions

Serve these Ultimate Mushroom Burgers immediately while they are hot and the cheese is melted and gooey. They pair perfectly with a side of crispy french fries, onion rings, or a fresh salad. For an extra touch, consider adding a drizzle of balsamic glaze or a dollop of garlic aioli.

Leftovers can be stored in the refrigerator in an airtight container for up to 3 days. To reheat, you can microwave the burger for a minute or two, but the bun might get soggy. A better option is to reheat the burger in a skillet over medium heat or in a 350°F (175°C) oven until heated through.

I don’t recommend freezing the assembled burgers, as the texture of the mushrooms and the quality of the cheese may be compromised upon thawing. However, you can freeze the cooked burger patties and sautéed mushroom mixture separately for up to 2 months. Thaw them overnight in the refrigerator before reheating and assembling.
