Ingredients

• 400g (14 oz) cremini or button mushrooms, finely chopped
• 1 small onion, finely chopped
• 2 cloves garlic, minced
• 1/2 cup rolled oats, ground into oat flour or use oat flour directly
• 1/4 cup cooked quinoa (optional but adds texture and protein)
• 2 tbsp ground flaxseed mixed with 6 tbsp water (flax egg)
• 2 tbsp soy sauce or tamari for gluten-free
• 1 tsp smoked paprika
• 1 tsp dried thyme
• Salt and freshly ground black pepper, to taste
• 2 tbsp olive oil or vegetable oil for frying
• Burger buns, your choice (whole grain, brioche, gluten-free, etc.)
• Optional toppings: lettuce, tomato slices, pickles, vegan cheese, mustard, ketchup, vegan mayo

Equipment

• Large skillet or frying pan
• Mixing bowls
• Food processor or sharp knife (for chopping mushrooms)
• Measuring cups and spoons
• Spatula or wooden spoon
• Baking sheet or plate for resting patties
• Grill or grill pan (optional)

Instructions

1. Prepare the flax egg: Combine 2 tablespoons of ground flaxseed with 6 tablespoons of water in a small bowl. Stir and set aside for 10 minutes until it thickens.
2. Chop the mushrooms and onion: Using a food processor or a sharp knife, finely chop the mushrooms and onion until they resemble a coarse mince. This helps create a meaty texture.
3. Sauté the vegetables: Heat 1 tablespoon olive oil in a skillet over medium heat. Add the chopped mushrooms, onion, and garlic. Cook for 8-10 minutes, stirring frequently, until the mixture is soft and most of the moisture has evaporated. Remove from heat and let cool slightly.
4. Mix the burger base: In a large bowl, combine the sautéed mushroom mixture, oat flour, cooked quinoa (if using), flax egg, soy sauce, smoked paprika, thyme, salt, and pepper. Use your hands or a spoon to mix thoroughly until the mixture holds together well. If too wet, add a little more oat flour; if too dry, add a splash of water.
5. Form the patties: Divide the mixture into 4 equal parts and shape each into a burger patty about 1/2 inch thick. Place the patties on a plate or baking sheet.
6. Cook the patties: Heat the remaining 1 tablespoon olive oil in the skillet over medium heat. Fry the patties for 4-5 minutes on each side, until golden brown and heated through. Alternatively, you can grill the patties on a preheated grill or grill pan for a smoky flavor.
7. Assemble the burgers: Toast the burger buns lightly if desired. Place each patty on the bottom bun and add your favorite toppings such as lettuce, tomato, pickles, vegan cheese, and condiments. Top with the other half of the bun.
8. Serve immediately: Enjoy your delicious mushroom burgers hot with a side of fries, salad, or your preferred side dish.

Tips & Variations

For a firmer burger, add a tablespoon or two of breadcrumbs or ground nuts to the mixture. This helps bind the patties better and gives a nice crunch.

Experiment with mushrooms: Try a mix of portobello, shiitake, or oyster mushrooms for a more complex flavor profile.

Make it vegan: Skip cheese or use your favorite vegan cheese to keep this burger 100% plant-based.

Add spices: For a spicy kick, add chili powder or cumin to the burger mix.

Make it gluten-free: Use gluten-free oat flour and buns to accommodate gluten sensitivities.
