With burger and backyard BBQ season upon us, it’s time we take a look at an old classic recipe - Curried Sweet Potato Burger.

I originally wrote this recipe over 6 years ago! And during that time, it's become a family favorite. And so, I decided it was time to give this recipe a makeover.

These burgers have it all! They are packed with protein, filled with veggies, and seasoned to perfection. Then they are topped with homemade cilantro aioli and tomato chutney for a vegan sandwich that is out of this world.

Let's take a closer look at this new and improved recipe.

Ingredients & Substitutions

This is the ultimate vegan burger recipe. It is packed with protein, filled with veggies, and seasoned to perfection.

Here is everything you need.

• Red Lentils
• Sweet Potato - Feel free to use yams. You can also use canned sweet potato puree to save on time.
• Quinoa - Either red or white quinoa works.
• Garlic
• Onion
• Spices - You will need a combination of cumin, coriander, turmeric, paprika, cayenne, salt, and pepper
• Spinach - Either fresh or frozen works.
• All-Purpose Flour - For a gluten-free burger, use a 1:1 Gluten-Free Flour Baking Blend. (<<affiliate link)
• Oil - Any oil will do. I recommend coconut, avocado, or olive.
• Tomato Chutney - Either homemade chutney or storebought will do.
• Vegan Mayo - My favorite brand is Just Mayo. It is shelf-stable and has a similar price point to non-vegan mayonnaise. However, any vegan mayo will do.
• Fresh Cilantro
• Fresh Arugula - This is used as a topping. You could also use spinach or mixed greens.
• Buns - I like to use either slider buns or ciabatta rolls.

Step-by-Step Instructions

Step One - Cook the Lentils & Quinoa

To begin, rinse the lentils and quinoa thoroughly.

Pro Tip: Both quinoa and lentils should always be first rinsed in a fine-mesh sieve until water runs clear. This is key for getting a clean, nutty flavor. Otherwise, quinoa can sometimes taste dirty and gritty.

Cook the lentils and quinoa separately. Add 2 parts water for every 1 part quinoa and lentils and bring to a boil. Cover, reduce heat to a simmer and cook until the water is completely absorbed about 20 minutes.

Remove from heat and fluff with a fork. Set aside until ready to use.

Step Three - Make the Patties

Sauté the onions and garlic in until translucent. Add to cooked lentils along with spices, quinoa, spinach, and mashed sweet potatoes. Stir to combine. While stirring add flour until fully incorporated. Cook for an additional 5 minutes to ensure the flour is no longer raw.

Shape into patties and refrigerate for 2-3 hours.

Step Four - Cook the Patties

Heat coconut oil over medium heat in a nonstick skillet. Cook patties for about 5 minutes on each side until slightly browned.

If you want to grill these burgers, it is best done on an electric grill. Set your grill to 450F and cook the burgers on each side for 4-5 minutes, until the patty is cooked all the way through and you have dark grill lines on the skin of the burger.

Serving and Storing

Serving - Prepare the aioli by mixing together all the ingredients. Top each burger with aioli, chutney, and arugula and serve immediately.

Storing - Store leftover patties in the refrigerator for up to 3 days or the freezer for up to 3 months. When ready to eat, gently reheat over the stove until the patties are cooked all the way through. Store leftover chutney and aioli in the refrigerator for up to 7 days.

Make in Advance - Make these patties up to 2 months in advance. Once the patties are shaped, freeze the patties on a single layer. Once the patties are frozen all the way through, transfer them to an airtight container or Ziplock bag and freeze them. Cook them directly from the freezer.

Recipe Tips

1. Always rinsed quinoa and lentilsthrough a fine-mesh sieve until water runs clear. This is key for getting a clean, nutty flavor. Otherwise, quinoa and lentils can taste dirty and gritty.
2. Save time and use canned sweet potato puree in place of whole sweet potatoes.
3. Let the oil get very hot before adding the burgers. Otherwise, the oil will soak into the patties making them greasy and preventing them from browning.

Variations - Feel free to swap out a 1:1 gluten-free flour blend for all-purpose flour and serve on a gluten-free bun for a gluten-free sweet potato burger.
