Even if you don’t like eggplant, you will love these eggplant burgers, which really don’t taste like eggplant at all! Try them with Spicy Onion-Pepper Relish or your favorite burger toppings.

Curried Eggplant, Lentil, and Quinoa Burgers with Onion-Pepper Relish: Even if you don't like eggplant, you will love these burgers, which really don't taste like eggplant at all! Try them with Spicy Onion-Pepper Relish.

Leftovers give you two separate good feelings. When you first put them away, you feel really intelligent–“I’m saving food!” And then, after a month, when hair is growing out of them and you throw them away you feel…really intelligent–“I’m saving my life!”

–George Carlin

I often think of eggplants like George Carlin’s leftovers.  When you buy one, you feel really good for bringing home this healthy, shiny vegetable.  Then you put it into your fridge and forget it for a week or so, and when you pull it out, it’s all dull and sunken in places, and you feel….  Well, that’s where the comparison ends because, if you’re like me, you feel guilty that this once-beautiful food has gone to waste.

It used to happen to me more often than I want to admit until I hit upon a solution: If I haven’t used the eggplant after two or three days, I cut it in two and roast it in my toaster oven.  Eggplant will last longer once it’s cooked, giving me time to figure out what new and adventurous recipe I want to create with it (though most of the time my cooking muse is silent and it becomes baba ganoush).

Eggplant, Lentil, and Quinoa Burgers on a plate

Baba will probably always be my favorite way to use roasted eggplant, but these veggie burgers and the pesto I posted earlier this summer tie for second place.  Even if you don’t like eggplant, you will love these burgers, which really don’t taste like eggplant at all (ask E the Eggplant Hater, who enjoyed her burger even knowing it contained eggplant).

I used a new favorite ingredient to bind together the eggplant and lentils:  Quinoa flakes are quinoa that has been steamed and flattened so that you can use it like oatmeal as a hot cereal.  It cooks quickly and in this recipe doesn’t have to be pre-cooked at all. 

But if you don’t have quinoa flakes, regular old-fashioned oats also work. Just pulse them in the food processor after measuring to chop them up a little (no need to turn them into flour.)

Curried Eggplant and Lentil Burger made with oats

If you’re not a curry lover, try changing the seasonings to suit your taste.  The ingredients go well with chipotle and chile powder or thyme, basil, and oregano.   Have fun and be adventurous!

One note: The batter is wetter than most veggie burgers’, so I form the burgers in a hot skillet and pre-brown them before baking or air frying them. Forming them into patties with your hands can be messy, so I advise placing a ring mold into the skillet, filling it to about 1/2-inch thick, and lifting it off to use again. You may think that the batter will never thicken up, but it does, creating a meatier texture than you might expect.

Like most veggie burgers, these will probably fall apart if you try to cook them on a barbecue grill, but once they’re baked, they hold together well and can be reheated on the grill, making them a perfect food to bring to a Labor Day picnic.

Curried Eggplant, Lentil, and Quinoa Burgers

These tender burgers are lightly curry-flavored but not spicy. To add heat to your burger, top it with a little Spicy Onion-Pepper Relish, below.
Prep Time 25 minutes
Cook Time 50 minutes
Total Time 1 hour 15 minutes

Author Susan Voisin

Ingredients

  • 1 large eggplant (*see Notes below)
  • 1 cup cooked lentils
  • 3/4 cup quinoa flakes or rolled oats (Chop old fashioned oats in food processor after measuring and before using.)
  • 1/2 small onion minced
  • 2 cloves garlic cloves minced or pressed
  • 2 teaspoons potato starch, corn starch, or arrowroot
  • 1 teaspoon curry powder
  • 1/2 teaspoon ground cumin
  • 1/2 teaspoon smoked Spanish paprika (spicy or mild)
  • 1/2 teaspoon salt (or to taste)
  • 1/2 teaspoon agave nectar (or other sweetener, optional)
  • 1/4 teaspoon ground coriander

Suggested Tools

  • 3-inch Ring Mold
Prevent your screen from going dark

Instructions

  • Preheat oven to 425 F. Remove the top of the eggplant and cut it in half lengthwise. Place it cut-sides down on a baking sheet lined with parchment paper or silicon baking mat. Bake for 25 minutes or until the eggplant is completely sunken in and tender. Remove to a shallow dish and allow to cool completely. (You can do this even several days in advance and store in a covered container in the refrigerator.)
  • Once the eggplant is cool, discard any liquid that has accumulated and scrape the pulp from the peel. Place the pulp in a food processor and pulse a few times to make a coarse puree. Transfer to a medium-sized bowl and add the remaining ingredients. Mix very well and allow to stand at room temperature for at least 20 minutes.
  • Heat a large non-stick frying pan over medium-high heat. Wet your hands and form eggplant mixture into patties about 3 inches wide and 1/2 inch thick. (You can also form the burgers by spooning the mixture into the pan and using the back of a spoon to shape it into patties or by placing a ring mold into the pan and molding the mixture inside it.) Cook three or four at a time until well browned and then carefully flip over and brown the other side. Remove with a spatula and place each burger on a prepared baking sheet for oven baking or preheated air fryer basket.

Oven Instructions

  • Preheat oven to 425 F. Line a baking sheet with parchment paper or silicon baking mat. Place the browned burgers onto the prepared pan. Bake for 15-20 minutes, until burgers are cooked through.

Air Fryer Instructions

  • Preheat the air fryer to 400F. Place the browned burgers onto the hot air fryer basket and cook for 10-15 minutes, until cooked through. Exact time will depend on your air fryer.
  • Serve with traditional hamburger condiments or with Spicy Onion-Pepper Relish, below.

Notes

*After cooking, my eggplant provided about 1 1/2 cup or 10 ounces of pulp. If your eggplant is significantly larger, add more quinoa or oats and a little more starch. 
One burger made with quinoa flakes is 2 points on Weight Watchers Freestyle program; made with oats, it’s 1 point.

Curried Eggplant, Lentil, and Quinoa Burgers with Onion-Pepper Relish

I enjoyed the flavor of mild curry with the lentils and eggplant and, being the heat-lover that I am, spiced them up by serving them with this fiery relish made from onions and a jalapeno pepper from my garden.

    I made these with a little more than half a cup a cup of quinoa flour (1/2 plus 1/8 of a cup of flour) and they turned out perfect. I usually hate making veggie burgers because they always seem to fall apart on me…not these. They stayed in patty formation in the browning and eating stages. Yum!

    Hi, as of 9/8/10 I decided to become a vegan. Over the past 15 years or so, I’ve tried several different veggie burgers. Those past veggie burgerssent me back to meat. These are different. I made these burgers and I honestly have to say they are great! I love the crunch from the quinoa and the great taste. I’m a burger guy and don’t like mushy burgers. I am going to need your help with this new lifestyle change and these burgers is a start! I modified the recipe some. First, I grilled my eggplant, brushing it with olive oil first. I grilled it for 30 minutes turning them half way thru. I used tapicoa flour for the starch and brown rice sryup for the sweetner. To me, the smoked paprika is a must. I love these burgers! I eat mine on a bun topped with cole slaw. I also use this recipe as meatballs for my spaghetti. This is a 10 star recipe! thanks! dj

    These were delicious!! A great way to use eggplant. My husband refuses to eat eggplant and hates the taste of it. I didn’t tell him til after he told me how much he enjoyed the burgers. You can’t even taste it. I added some cayenne pepper to spice them up and bit. Served them on toasted Ezekiel Bread with some garlic hummus, yum!! Thanks for another great recipe.

    Hi again Susan,

    Just wanted to let you know these burgers traveled well on our epic road trip and were delicious every time we ate them. Back home, I just made a second batch a couple of days ago, and realized that I had somehow missed the part about pan-frying them and I had only baked them. This is better for me anyway, and, like lovemyfamily just above, they turned out great just baking them both times, and did not fall apart. They even turn easily on the parchment from browning purposes. They are more golden cooked this way than dark brown, but that is not an issue for me. These will be one of my go-to recipes. Thanks!

    Oh.My.Gawd. I made these for dinner tonight with the onion relish… they were AMAZING!!!! My husband and I both LOVED them. I actually added some chopped red pepper to the onion relish (my husband doesn’t like onions so I did this to mask the onion flavour a little) and it was soooo good. I love eggplant and am so happy everytime I find a new way to use it! Thank you!

      You might try covering the pan for part of the cooking time to steam them a little. Other than that, I suggest long cooking on each side at a low setting. Good luck!

    I would really love to try these out Susan. Looks and sounds delish! I just recently (last week) tried Indian food for the first time and am in love. Was wonderig what type of curry powder you use..? Also, do you think cardamom would work in these ?

      I buy a curry powder called Maharajah from Penzey’s or from the Spice House, both of which have online stores. Cardamom would work if you blend it with cumin and other seasonings (which is what curry powder is, a mixture of spices). If you can get it, I really recommend the Maharajah, though.

      I haven’t tried spelt flakes, but if they cook in about the same time as quinoa flakes or oatmeal, they should work. If you try, please let me know how they come out!

    Hi Susan,
    I just discovered your site yesterday and am already addicted! These burgers look gorgeous. I plan to make them this evening. My husband’s not a big aubergine fan but after reading the reviews I’m hoping he won’t even notice.

    I made your samosa wraps and lentil and veg stew last night and they went down a treat, particularly the wraps. They were so tasty. Thank you again.

    Oh by the way I can’t get quinoa over here (I’m Irish living in Damascus) so was wondering if bulghur would work?

    • SusanV

      November 23, 2010 at 8:10 am

      Thanks for all the great comments, Kim. I worry that bulghur won’t hold these burgers together very well. I suggest oatmeal (the sliced oats, not whole ones) or oat flour (oats ground in a blender) instead of the quinoa flakes. Good luck!

    Hi Susan,

    Thank you for the reply. I appreciate how busy you are.

    Well you were right about the bulghur-it was hard to keep them together but I managed it by using your method of forming them with the spoon and just being really gentle. They were delicious. My husband hadn’t a clue they contained aubergines so he was pleasantly surprised.

    I’m in the middle of roasting some tomatoes for bruschetta. Your description sounded so nice I had to try it.

    Again thank you so much for taking the time to test and perfect all the recipes. Your efforts are very much appreciated.

I didn’t make the salsa because these pair PERFECTLY with hummus, my fav. I have tried many many veggie burger recipes and this is one of the very best in terms of not falling apart as many recipes tend to do.

    Wow. These are really, really good. They are so flavorful! Everyone in my family loved them and agreed they were repeat worthy. They really weren’t even that hard either! I cooked the eggplant in the morning and then finished the recipe in the evening. I didn’t have the smoked paprika so I just used the Hungarian sweet. Amazingly the regular supermarket in a small town in Australia, Coles, carries quinoa flakes and agave nectar so it was easy to get the ingredients too! We had ours with the relish and romaine lettuce and tomato slices and sliced beetroot and they really didn’t need anything else to be absolutely perfect. The sliced beetroot is a really great addition – I very much recommend it. I love that these are so healthy and also so tasty. I love food with lots of herbs and spices and these burgers fit the bill! I was also impressed by how well they stuck together – something vegan burgers don’t usually do so well. A++! Thanks for yet another fantastic recipe Susan! Can’t wait for your cookbook!
