Description

These Marinated Portobello Mushroom Burgers are a delicious and healthy vegetarian alternative to traditional beef burgers. The mushrooms are marinated in a savory mix of olive oil, soy sauce, apple cider vinegar, and spices, then grilled to perfection and served on toasted buns with fresh, classic toppings. Perfect for a quick weeknight dinner or a casual weekend meal.


Ingredients

Scale

Marinade

  • 2 Tbsp olive oil
  • 2 Tbsp soy sauce
  • 1 Tbsp apple cider vinegar
  • 1 tsp brown sugar
  • 1/4 tsp oregano
  • 1/4 tsp garlic powder
  • 1/4 tsp onion powder
  • 1 tsp smoked paprika
  • Freshly cracked pepper (about 10 cranks of a pepper mill)

Main Ingredients

  • 2 portobello mushroom caps (about 1/2 lb total)
  • 2 buns

Optional Toppings

  • 1 cup spring mix
  • 1 tomato, sliced
  • 1/4 red onion, sliced into rings
  • 4 Tbsp mayonnaise


Instructions

  1. Prepare Marinade: In a small bowl, stir together the olive oil, soy sauce, apple cider vinegar, brown sugar, oregano, garlic powder, onion powder, smoked paprika, and freshly cracked pepper until well combined.
  2. Marinate Mushrooms: Remove the stems from the portobello mushrooms. Place the mushroom caps gill side up in a shallow dish. Pour some of the marinade into the gills, then flip the mushrooms and pour the rest of the marinade over the top. Let them marinate for 30 minutes, flipping occasionally to ensure even coating.
  3. Grill Mushrooms: Heat a grill or grill pan over medium to medium-high heat. Once hot, add the marinated mushrooms and cook for about 7 minutes on each side, or until the mushrooms are tender and have released most of their liquid.
  4. Assemble Burgers: Toast the buns if desired. Place each grilled mushroom cap on the bottom bun and top with mayonnaise, sliced tomato, onion rings, and spring mix or lettuce. Cover with the top bun and serve.

Notes

  • You can save the mushroom stems to chop and add to an omelette or freeze with vegetable scraps for making stock later.
  • For a vegan option, substitute mayonnaise with vegan mayo or avocado spread.
  • Make sure to flip the mushrooms occasionally while marinating to maximize flavor absorption.
  • Use a grill pan or outdoor grill depending on availability; stovetop grilling works well too.
