Skeptics beware. Roll up those sleeves and get ready, these veggie burgers will have you looking forward to ‘Meatless Monday.’  Don’t get me wrong, I positively love a good ‘can’t put it down cause my toppings are gonna fall apart, grease drippin’ down my arms‘ burger. If a meaty burger can be that irresistible, why can’t veggie burgers leave you just as satisfied?

The answer? They can! Watch how to make them right here:

“Ya right lady,” you say. I can feel your skepticism from this side of the Internet. But if my husband, whose eyebrows raise in apprehension toward any food that can be labeled ‘earthy crunchy,’ can approve of these burgers they really are fit for any meat loving hamburglar.

Big Mouth Spicy Veggie BurgersWow. Just wow. What a Monday morning to live in New England. Having mentioned it before, but I’m not much of a football fan. Regardless, I can appreciate watching a great game and last nights was the definition of just that. After a day of binging on dips, chips, and all other indulgent finger food. Treat yourself to something that seems like an indulgence but is loaded with super food goodness.

Steamed sweet potato is tender and sweet while quinoa and black beans add savory texture. Let’s not forget the biggest star here. That good old sneaky sriracha along with a proper blend of spices. Just a little of that magic red sauce goes a long way to bring a warm mellow heat to each bite. All mixed together and formed into large patties to give you that ‘Steakhouse Burger’ meal right there in your kitchen, without the cost and without the meat!

And the extras! Can’t forget about those.

Caramelized red onions and goat cheese. Salty, buttery, creamy on top of a seriously “beefy” veggie burger, crispy on the outside and soft on the inside. Loaded up on a toasted potato bun smothered with spicy aioli. Of course, you can throw some lettuce and tomato too add to the party already happening between those two buns.

  • 2 tbsp olive oil (extra virgin)
  • 1 tbsp kosher salt

  • 1 tsp sriracha

  • 2 tbsp goat cheese
  • 1 large hamburger roll
  • 1 tbsp caramelized red onion
  • 3/4 cup spicy veggie burger mix (formed into a patty)


Spicy Veggie Burger Mix

  1. Wash sweet potatoes and cut in quarters.  Add to steamer and cook until soft through center and mashable.  Allow to cool slightly and remove skins.
  2. Add sweet potato to large bowl and mash until smooth.  Add remaining ingredients and stir well to combine.
  3. Form mixture into burger patties using about 3/4 to 1 cup of mixture per patty for ‘Big Mouth’ burgers.*

Caramelized Red Onion

  2. Cook for about 30 minutes until onions have turned a rich brown color.

  1. In a non stick skillet, heat 1 tablespoon Extra Virgin Olive Oil over medium low heat.  Cook patty on both sides for 5 minutes until crispy on the outside and hot through center.  About 1 minutes before burger is finished cooking, add caramelized red onions and goat cheese to the top of the patty so it will melt slightly.
  2. In a small bowl, whisk together sriracha and mayonnaise.  Spread on both sides of a large toasted burger bun, add the burger patty with caramelized red onions and goat cheese.


*For smaller burger sizes, use 1/2 cup of spicy veggie burger mix.

*If flaxseed meal is unavailable, unseasoned breadcrumbs can be substituted.

Oooh! I'm not a huge fan of veggie burgers as they almost always contain chickpeas or lentils (which I hate), but this definitely looks like something that I could enjoy! Especially with caramelised onions - yum! I'll have to give this a try for sure. :)

I have GOT to try this veggie burger. I have been looking to make my own at home since the ones at stores can be a bit expensive at times. This looks amazing.
