How To Make Mushroom Veggie Burgers
Prepare the ingredients: cook the quinoa, clean and roughly chop the onions, carrots, mushrooms and garlic.
Step 1. Chop the carrots and onions
Place the carrots, onions, and garlic into a food processor and pulse the food processor until they're in the shape of crumbles. Remove them from the food processor and set them aside.
Step 2. Chop the mushrooms
Add the mushroom pieces and walnuts; process into crumbles.
Step 3. Cook the veggies
Heat the oil in a skillet over medium heat and add the crumbled vegetables. Cook them until they become soft - about 5 to 8 minutes.
Step 4. Add Egg and cheese
Place the cooked vegetables into a strainer and squeeze out as much liquid as you can. Place the strained vegetables into a large bowl and add tamari sauce, cooked quinoa, egg, and cheese.
Step 5. Chill the burger mix
Mix everything together and place the bowl in the refrigerator for 45 minutes which will make it easier to form the mixture into patties.
Step 6. Make the patties
Use your hands or a burger press to form the mixture into 6 patties.
Step 7. Cook the veggie burgers
Heat the remaining oil in a large skillet over medium-high heat and cook the veggie patties for 5 minutes on each side.
Note: If your food processor is large enough, you can process all of the vegetables together in one step.
Ingredient Notes & Substitutions
Portabella Mushrooms give these burgers an earthy flavor, and they are the best choice of mushroom to use in this recipe for their meaty texture.
Substitute portobello mushrooms with 8 ounces of baby bellas, shiitake mushrooms, or white button mushrooms.
Onion. The best type of onion to use in these mushroom veggie burgers is an all-purpose onion such as a yellow, or Vidalia onion.
Garlic. Fresh garlic is always the best choice when cooking, but it can be substituted with ⅛ teaspoon of garlic powder.
Quinoa. Quinoa grows in a variety of colors, most commonly white, red, black or mixed. You can use any color of quinoa that you like in this recipe.
Quinoa can be substituted with an equal amount of cooked brown rice in this recipe.
Walnuts add a little more meaty texture as well as protein. If you don't care for walnuts you can use another type of nut.
Substitute the walnuts with an equal amount of raw cashews, almonds, or pecans.
Tamari Sauce brings all of the flavors together with its umami flavor.
Substitute tamari sauce with an equal amount of soy sauce or coconut aminos.

Storing and Using Leftovers

Recipe Tips and Questions
Tips
- If you are in a hurry, place the burger mixture into the freezer for 15 to 20 minutes.
- If the burgers are still too moist. Add a quarter cup of unseasoned bread crumbs or rolled oats to bind them together.
Questions
Veggie burgers are more fragile than meat burgers. If you want the grilled flavor in your veggie burger, bake the burgers first for 15 to minutes in the oven at 375. Allow them to cool slightly and then toss them onto the grill for a few minutes.
