Why we love it:

I love a burger made from just about any type of patty. Slicing portobello mushrooms into thin slices then cooking them gives a great texture to the final sandwich when you restack them into a patty shape. It's definitely worth a few extra knife cuts.


  • 114 pounds Portobello Mushroom (about 4-5 caps)
  • 1 Tablespoon Paprika
  • 1 teaspoon Onion Powder
  • 1 teaspoon Garlic Powder
  • 12 teaspoon Kosher Salt
  • 1 teaspoon Canola Oil
  • 12 teaspoon Unsalted Butter
  • Provolone Cheese (4 slices - or cheese of choice)
  • 2 Tablespoons Mayonnaise
  • 2 Tablespoons Sriracha
  • 1 Lemon (zest and juice)
  • 4 Burger Buns
  • 1 Avocado
  • 3 Carrots
  • 1 Cucumber

Cooking Instructions


    Twist off the stems and reserve in the freezer for your next batch of stock. Holding your knife parallel to the cutting board and carefully place your palm on the top of one cap at a time. Slice the cap into thin layers, aim for 3-4 from each cap. Place in a bowl and repeat.

    In the bowl, add the spices, including salt. Add the oil and toss to coat well.

  • 2. COOK

    In a large non-stick or cast iron skillet, heat the butter until hot. Add mushroom caps in 1 layer, might need to do 2 batches so plan accordingly. Cook for about 2 - 4 minutes or until browned and tender, flip. Cook the other side until done throughout. Remove to a baking sheet and repeat until all slices are cooked.

    Organize the caps into burger shapes, overlapping then to fill the size of the bun, so not just stacked straight on top of each other. Lay cheese over top and either broil to melt, or place them back in the pan and cover it until the cheese is melted.

  • 3. SAUCE

    Meanwhile, stir together the mayo, sriracha, and zest and juice of the lemon.

  • 4. BUNS

    Toast buns if desired. Spread evenly with sauce and slices of avocado.

  • 5. CRUDITÉ

    Wash and slice carrots and cucumber into sticks. Plate.

  • 6. SERVING

    Slide the “burgers” on the buns and serve with crudité.
