Tools and Preparation

Before you get started on making your Mushroom Veggie Burgers, gather the necessary tools. Having the right equipment will make the process smoother and more enjoyable.

Essential Tools and Equipment

Food processor
Large sauté pan
Baking sheet
Parchment paper
Measuring cups and spoons

Importance of Each Tool

Food processor: Essential for combining ingredients quickly and evenly, ensuring a consistent texture in your burgers.
Large sauté pan: Allows you to cook the onion and mushrooms evenly without overcrowding.
Baking sheet: A must-have for baking the patties to perfection while keeping them from sticking.

Ingredients

For the Burgers

1 small onion, chopped
16 ounces cremini (baby bella) mushrooms, sliced (or a blend of portobello, shiitake or cremini)
3 cloves garlic, minced
1 teaspoon dried thyme
1 teaspoon smoked paprika
½ cup raw walnut halves
1 ¼ cups cooked pearled barley (see Notes for subs)
1 cup cooked pinto or black beans (rinsed and drained)
1 Tablespoon nutritional yeast
2 Tablespoons vegan worcestershire sauce (see Notes)
½ cup panko breadcrumbs
1 teaspoon fine sea salt
black pepper

For Garnish

2 tablespoons fresh parsley, finely chopped

How to Make Mushroom Veggie Burgers

Step 1: Sauté the Vegetables

Preheat a large sauté pan over medium-low heat.
Add chopped onion and sliced mushrooms to the pan.
Stir occasionally until the liquid from the mushrooms is mostly evaporated (about 15 minutes).
Add minced garlic, thyme, and smoked paprika. Cook for an additional 2–3 minutes until well combined.

Step 2: Prepare the Oven

Preheat your oven to 400° F.
Line a baking sheet with parchment paper to prevent sticking.

Step 3: Process the Mixture

In the bowl of your food processor, pulse walnut halves until coarsely crumbled.
Add in the sautéed mushroom mixture along with cooked barley, beans, nutritional yeast, vegan worcestershire sauce, panko breadcrumbs, salt, and pepper.
Process until everything is incorporated but still has visible pieces of beans and mushrooms.

Step 4: Form Patties

Using a scant ½ cup of mixture per patty will yield approximately 8 burgers.
If desired, brush patties with vegan worcestershire sauce and sprinkle with black pepper.

Step 5: Bake the Burgers

Place formed veggie burgers on your prepared baking sheet.
Bake for 30 to 35 minutes. Flip at the 15-minute mark. They should be firm and golden brown when finished.

Step 6: Pan-Seared Option

For pan-seared veggie burgers: Preheat a cast-iron skillet over medium heat.
Add 2 tablespoons of high-heat cooking oil to the skillet.
Place 2 to 3 burgers in the pan without overcrowding. Cook about 5 minutes per side until nicely charred.
Transfer finished burgers to a paper towel-lined plate to absorb excess oil.

Enjoy your homemade Mushroom Veggie Burgers hot off the grill or baked fresh from your oven!

How to Perfect Mushroom Veggie Burgers

To make the best mushroom veggie burgers, consider these helpful tips that will elevate your cooking game.

Use Fresh Ingredients: Fresh mushrooms and herbs significantly enhance flavor compared to dried or old ingredients.
Don’t Over-process the Mixture: Leave some texture in the mixture for a heartier bite; avoid making it too smooth.
Chill Before Cooking: Chilling the patties for at least 30 minutes helps them hold together better when cooked.
Experiment with Spices: Feel free to add your favorite spices or herbs to customize the flavor profile.
Check for Doneness: Ensure burgers are firm and golden brown before serving, whether baking or pan-searing.
Store Properly: If you have leftovers, store them in an airtight container in the fridge for up to three days.

Best Side Dishes for Mushroom Veggie Burgers

Pairing mushroom veggie burgers with complementary sides can create a balanced meal. Here are some excellent side dish ideas.

Sweet Potato Fries: Crispy sweet potato fries offer a sweet contrast to savory burgers.
Quinoa Salad: A light quinoa salad with vegetables is nutritious and refreshing.
Roasted Vegetables: Seasoned roasted veggies provide a warm, hearty complement.
Corn on the Cob: Grilled corn adds a touch of sweetness and is perfect for summer cookouts.
Mixed Green Salad: A simple mixed green salad dressed lightly enhances freshness on your plate.
Chips and Salsa: For a casual vibe, serve with crunchy chips and zesty salsa for dipping.

Common Mistakes to Avoid

Making Mushroom Veggie Burgers can be simple, but there are common pitfalls. Avoid these mistakes for the best results.

Using too much moisture: Excess liquid can make your patties fall apart. Ensure mushrooms are sautéed until dry before mixing.
Not seasoning enough: A bland burger is disappointing. Season each component, including the mushroom mixture, to enhance flavor.
Skipping the chilling step: Failing to chill formed patties can lead to crumbling during cooking. Refrigerate for at least 30 minutes before cooking.
Overmixing the ingredients: Overprocessing can result in mushy patties. Pulse just until combined; some texture is a good thing!
Ignoring cooking temperatures: Cooking at too high a temperature can burn the outside while leaving the inside undercooked. Use medium heat for pan-searing and monitor closely.

Refrigerator Storage

Store leftovers in an airtight container.
They will last for up to 4 days in the fridge.

Freezing Mushroom Veggie Burgers

Place cooled burgers in a freezer-safe bag or container.
They can be frozen for up to 3 months for best quality.

Reheating Mushroom Veggie Burgers

Oven: Preheat to 375°F and bake for 10-15 minutes until heated through.
Microwave: Heat on medium power for about 1-2 minutes; check frequently to avoid drying out.
Stovetop: Warm in a skillet over medium heat for about 5 minutes per side.
