Step-by-Step Guide to Making the Best Portobello Mushroom Burger
Step 1: Clean and Prep the Mushrooms
Start by cleaning the portobello mushrooms. Gently remove the stems and wipe the caps with a damp cloth to remove any dirt. You can also scrape out the gills with a spoon, but it’s optional.
Step 2: Make the Marinade
In a small bowl, whisk together the olive oil, balsamic vinegar, minced garlic, Dijon mustard, smoked paprika, salt, and black pepper. This marinade enhances the mushrooms’ natural umami flavor.
Step 3: Marinate the Mushrooms
Place the mushrooms in a shallow dish and pour the marinade over them. Let them sit for at least 15 minutes, flipping them halfway through to absorb the flavors evenly.
Step 4: Preheat the Grill
Heat your grill or grill pan to medium-high heat. Lightly oil the grates to prevent sticking.
Step 5: Grill the Mushrooms
Place the marinated mushrooms on the grill, gill-side down. Grill for 4-5 minutes per side, brushing them with any remaining marinade. When they’re tender and slightly charred, they’re ready.
Step 6: Toast the Buns
While the mushrooms are grilling, lightly toast the burger buns on the grill for 1-2 minutes until golden brown.
Step 7: Assemble the Burger
- Spread mayonnaise, Dijon mustard, and ketchup on the toasted buns.
- Add a layer of fresh lettuce.
- Place the grilled portobello mushroom on top.
- Add a slice of cheese (it will melt beautifully from the heat).
- Layer on tomato slices and red onion rings.
- Close the bun and press gently.
Step 8: Serve and Enjoy
Serve your Grilled Portobello Mushroom Burgers hot with a side of fries, a fresh salad, or grilled vegetables.
