This is a sponsored conversation written by me on behalf of Hellmann’s. The opinions and text are all mine.

I’m so excited to be working with Hellmann’s and to share these Homemade Veggie Burgers with Herb Mayonnaise featuring Hellmann’s Plant-Based Mayonnaise! These vegan burgers are packed with flavor and easy-to-find ingredients. Even my meat-loving kids enjoyed them!

If you’re looking to add more plant-based products to your diet Hellmann’s Plant-Based Mayonnaise is an easy switch, with the same great taste as Hellmann’s Real Mayonnaise. No one in my family could taste the difference. Hellmann’s Plant-Based Mayonnaise is just as creamy and 100% plant-based.
Hellmann’s Plant-Based Mayonnaise is just as versatile as Hellmann’s Real Mayonnaise. It was a great addition to both the burger patties and herb mayonnaise topping for these veggie burgers. You can use Hellmann’s Plant-Based Mayonnaise in all your favorite recipes for the same great taste.

These veggie burgers are easy to make but here are a few things that will help…
Equipment You May Need
- Food Processor – If you have a food processor, I strongly recommend using it for this recipe. If you don’t have one, you can mash the patty ingredients with a fork or even a potato masher if you have to.
- Spatula – A silicone spatula works great to scrape down the sides of the food processor while combining the patty ingredients.
- Grill Spatula – Although these veggie burger patties stay together quite well, a strong metal spatula will help flip them without the patties falling apart.
- Parchment Paper – If you’re making the patties ahead, you can wrap them in parchment paper and store the patties in the freezer.

Veggie Burgers & Herb Mayonnaise Ingredients
- Hellmann’s Plant-Based Mayonnaise – The mayonnaise helps the burger patties stick together and is also the base in the Herb Mayonnaise.
- Mushrooms – I used baby bella mushrooms since they’re a bit “meatier”.
- Onion – I used a regular white onion, but any type should be ok.
- Black Beans – Drained canned black beans that have been rinsed work well.
- Brown Rice – Precook the brown rice or use leftover rice. Make sure the rice isn’t too “gummy”.
- Bread Crumbs – Plain bread crumbs or plain panko bread crumbs are good to use.
- Walnuts – Use unsalted raw walnuts and toast yourself before using.
- Paprika – I like smoked paprika in these patties but you could also use sweet or use your favorite spices instead.
- Garlic – I used garlic powder but you could also use minced garlic cloves.
- Salt/Pepper – Use a little salt and pepper in both the patties and Herb Mayonnaise.
- Lemon Juice – Fresh lemon juice works best if you can.
- Scallions – Chives would also work well.
- Rosemary – Fresh rosemary adds so much flavor and I wouldn’t skip it.
- Rolls – Choose your favorite burger roll. You can make the patties into any size you want even sliders!
- Fave Burger Toppings – We liked lettuce and tomato slices on our burgers but cucumber slices, pickles, or even sautéed mushrooms would be delicious.

How to Make Veggie Burgers with Herb Mayonnaise
Step One: Cook the mushrooms and onions until soft, cool.
Step Two: Place all patty ingredients in food processor and pulse until everything is finely chopped and starts to stick together.
Step Three: Form mixture into patties, freeze.
Step Four: Mix together all of the Herb Mayonnaise ingredients in a bowl, cover and refrigerate.
Step Five: Preheat grill, cook patties.
Step Six: Assemble burgers with your favorite toppings and the Herb Mayonnaise.

Serving Suggestions
- Serve these burgers right away after cooking.
- Top the burgers with your favorite vegan-friendly toppings such as lettuce, tomato, sliced cucumber, onion, sautéed mushrooms, or whatever else you like. These homemade Spicy Pickles or Pickled Onions would also be delicious.
- Serve with your favorite summer sides such as potato chips, veggie salad, coleslaw, potato salad, or pasta salad.
Quick Tips for Best Results
- I strongly recommend a food processor for this recipe. Although you can make the patties by hand, a food processor really helps chop and combine all the ingredients.
- The patties can stick a little to the grill/pan so coat them with a nonstick spray or olive oil before cooking.
- You can form the patties into any shape you like including 4 smaller patties. If you do make smaller patties be sure to adjust the cooking time. Or you can also double the recipe to make 4 large patties.
- If the ingredients don’t start sticking together in the food processor, add a little more mayonnaise to help everything combine.
- Although these patties stay together fairly well, be gentle handling them so that they do not fall apart. Freezing the patties before cooking seems to help keep everything together.

Veggie Burgers FAQ
How should I store the Veggie Burgers and Herb Mayonnaise?
Store any uncooked patties in the freezer well-wrapped in a resealable bag or airtight container. Leftover cooked patties should be stored in a resealable bag or airtight container in the fridge. The Herb Mayonnaise should be stored covered in the fridge.
How long will the patties last?
The patties will last a few days in the fridge and uncooked patties that are well-wrapped could last several months in the freezer.
Substitutions?
Instead of paprika and garlic powder, you can use your favorite spices. Instead of plain bread crumbs you can use panko bread crumbs.
What else can I add to this recipe?
Add your favorite dried or fresh herbs and spices in both the patties and Herb Mayonnaise.
Can I make this vegan/vegetarian/low carb/gluten-free?
Here are some suggestions, but I can’t guarantee results. Be sure as always to check particular brands and ingredients if you’re following a specific diet or have diet restrictions or allergies.
Vegan – This recipe is vegan but be sure to check your rolls and other ingredients.
Vegetarian – It’s vegetarian. Again, be sure to check specific brands and ingredients.
Low-Carb – You can try a lower-carb bread crumb and wrap the patties in lettuce leaves rather than rolls. You can try cauliflower rice instead of brown rice but I haven’t tried it in this particular recipe so I can’t guarantee results.
Gluten-Free -Try a gluten-free bread crumb and gluten-free rolls.
