Chicago Diner Mushroom Burgers are a “Meaty” Vegan Favorite

4

It’s time for another flashback recipe update! I first tried and posted about these Chicago Diner Mushroom Burgers back in 2009. I was looking for a mushroom burger recipe that wasn’t just a portobello mushroom on a bun, and stumbled upon this recipe by my friend Sarena. She adapted it from the old Recipezaar, where it was posted from Vegetarian Times. In other words, this recipe has been well tested!

Chicago Diner Mushroom Burgers Recipe - a riff on the meaty veggie burgers from a popular vegan restaurant. Dairy-free, egg-free and vegan (no beans!)

The Chicago Diner is a popular vegan restaurant in the Windy City that is well known for “meaty” veggie burgers. I’m not sure if they still serve a veggie burger just like this one, but the recipe was originally a copycat for a house favorite. They serve their veggie burgers on a wheat bun, and we suggest that you do, too.

These mushroom burgers are rich in flavor but relatively lean. The texture ends up firm on the outside, and a bit softer in the middle, much like some Amy’s veggie burgers.

Homemade veggie burgers like these are often too soft to simply fire on the grill. Store-bought ones have often been pre-baked and frozen to firm them up. To enjoy that outdoor experience, these mushroom burgers are baked and then grilled on foil, to ensure that they don’t fall through the slats!

Serves: 12 mushroom burgers
Ingredients
  • 4 cups mushroom broth or water
  • 1 cup diced roasted red peppers or 3 stalks celery, diced (I use red peppers)
  • 1 cup diced onion
  • ¼ cup soy sauce
  • 2 teaspoons onion powder
  • 2 teaspoons garlic powder
  • ½ teaspoon ground black pepper
  • 3 cups quick or rolled oats (quick oats yield a softer texture)
  • 4 cups diced mushrooms (portobello, cremini, button, or a combination)
  • ½ cup whole wheat flour
  • Salt, to taste (optional)
Instructions
  1. Put the broth or water, red peppers or celery, onion, soy sauce, onion powder, garlic powder, and black pepper in a medium pot over medium-high heat. Bring the liquid to a boil, reduce the heat to medium-low and simmer for 5 minutes. Stir in the oats, mushrooms, and flour and cook for 5 minutes. Taste and season with salt, if desired. Transfer the mixture to a bowl and let it cool completely.
  2. Preheat your oven to 350°F and line a baking sheet with parchment paper.
  3. With slightly damp hands, divide the mixture into 12 equal-sized pieces. Roll each into a ball and then flatten them into patties on your prepared baking sheet.
  4. Bake for 15 minutes. Flip and bake for 10 minutes, or until firm and toasted. Let the burgers cool completely to firm up more.
  5. Heat your grill to medium-high, place a piece of foil on grill and lightly grease it. Place the veggie burgers on the foil and grill for about 7 minutes per side. Alternatively, you can broil them in the oven for 2 to 3 minutes per side.
