This quinoa veggie burger is built from red quinoa, sweet potato, chickpeas, and grated zucchini, held together with ground flaxseed — no eggs, no breadcrumbs. It makes seven generous patties, freezes well, and costs a fraction of store-bought veggie burgers. If you want a homemade plant-based patty that actually holds its shape on the pan, this is a reliable one.
Before you start
The single most important step is letting the quinoa and sweet potato mixture cool completely before you mix in the other ingredients. Warm quinoa stays loose and steamy; it will make your patties soft in the middle and hard to shape. Stick the bowl in the fridge for 15–20 minutes — it speeds things up and makes a real difference to the final texture. The second thing that matters is how you mash: you want the chickpeas and sweet potato coarsely broken down, not smooth. Visible chunks give the patties structure. A potato masher works better here than a food processor, which tends to over-blend everything into a paste that won’t hold a patty shape.
Mistakes to avoid
- Skipping the pan-fry step: Going straight to the oven skips the crust that holds the patty together. The brief pan-fry sets the outside; the oven finishes the inside. Do both.
- Using wet zucchini: Grated zucchini holds a lot of water. Squeeze it in a clean kitchen towel before adding it to the mix, or your patties will be soggy and fall apart in the pan.
- Making the patties too thick: Thick patties don’t cook through evenly in 15 minutes at 350°F. Aim for about ¾ inch thick — they’ll firm up nicely without a raw center.
- Moving the patties too soon in the pan: Let them cook the full 3 minutes undisturbed before flipping. If they stick, they’re not ready to turn. A thin spatula helps.
- Under-seasoning the mix: Quinoa and chickpeas are bland on their own. Taste the mixture before shaping — if it seems flat, add a pinch more salt or chili powder before you commit to seven patties.
Ingredient notes
- Red quinoa: White or tri-color quinoa works fine here. Red holds its shape slightly better after cooking, but the difference in the final patty is small. Whatever you have is fine.
- Ground flaxseed (flax meal): This is the binder. Whole flaxseeds won’t work — they need to be ground to release the gel that holds everything together. A coffee grinder does the job in 30 seconds if you only have whole seeds.
- Chickpeas: Canned chickpeas are convenient; just drain and rinse well. Cooked dried chickpeas work too. White beans or black beans are reasonable swaps if that’s what’s in the pantry — the texture will be slightly softer but still holds.
- Pumpkin seeds: Listed in the instructions but not the ingredient list — use about ¼ cup. Sunflower seeds or chopped walnuts are easy substitutes with no real change to how the patty behaves.
Storage and reheating
Cooked patties keep in the fridge for up to 4 days in an airtight container. For longer storage, freeze them: lay patties flat on a baking sheet, freeze until solid (about 2 hours), then transfer to a zip-lock bag — they’ll keep for up to 3 months. Reheat from frozen in a 350°F oven for 18–20 minutes, flipping once, or in a dry skillet over medium heat for about 5 minutes per side. Skip the microwave if you can — it softens the crust and makes the patty rubbery. You can also freeze the uncooked shaped patties the same way; just thaw overnight in the fridge before pan-frying.
Quinoa Veggie Burgers with Sweet Potato & Chickpeas
Equipment
- Large saucepan with lid
- Potato masher
- 10-inch non-stick skillet
- Rimmed baking sheet
- Mixing bowl (large)
- Box grater or coarse grater
- parchment paper
Ingredients
- 2 cups vegetable broth low-sodium, 480ml
- 1 medium sweet potato peeled and diced, about 8 oz / 225g
- 1 cup red quinoa uncooked, rinsed well, 170g
- 1 cup chickpeas cooked, 165g (about half a 15 oz / 425g can, drained and rinsed)
- 1 small zucchini grated and squeezed dry, about 6 oz / 170g
- ¼ cup raw pumpkin seeds pepitas, 35g
- 5 ½ tablespoons ground flaxseed 55g
- 1 teaspoon sea salt
- ½ teaspoon black pepper ground
- ¾ teaspoon chili powder
- 1 teaspoon dried thyme
- 2 tablespoons olive oil for pan-frying, 30ml
Instructions
- Place the diced sweet potato and rinsed red quinoa in a large saucepan with the vegetable broth. Bring to a boil, then cover, reduce heat to low, and simmer for about 20 minutes until the quinoa is cooked and all liquid is absorbed. Transfer the mixture to a large bowl and refrigerate for 15–20 minutes until completely cool — this step is essential for patties that hold together.2 cups vegetable broth, 1 medium sweet potato, 1 cup red quinoa
- Add the chickpeas, grated and squeezed-dry zucchini, pumpkin seeds, ground flaxseed, sea salt, black pepper, chili powder, and dried thyme to the cooled quinoa mixture. Using a potato masher, coarsely mash the chickpeas and sweet potatoes — leave visible chunks for texture. Shape the mixture into 7 equal patties, about ½ inch (1.3cm) thick.1 cup chickpeas, 1 small zucchini, 1/4 cup raw pumpkin seeds, 5 1/2 tablespoons ground flaxseed, 1 teaspoon sea salt, 1/2 teaspoon black pepper, 3/4 teaspoon chili powder, 1 teaspoon dried thyme
- Preheat the oven to 350°F / 175°C (180°C fan-forced). Heat the olive oil in a non-stick skillet over medium heat. Pan-fry the patties for about 3 minutes on each side until lightly golden and crisp. Transfer the browned patties to a parchment-lined baking sheet and bake for 15 minutes until firm and heated through. Alternatively, grill the patties over medium heat for about 10 minutes, turning once.2 tablespoons olive oil

FAQ
Can I make these patties ahead of time?
Yes — shape the patties up to 24 hours ahead and refrigerate them on a plate covered with plastic wrap. Cold patties actually hold together better in the pan than freshly mixed ones.
My mixture feels too wet to shape. What do I do?
Add more ground flaxseed, one tablespoon at a time, and let the mix sit for 5 minutes — flax absorbs moisture as it sits. Wet zucchini is usually the culprit, so squeeze it harder next time.
Can I cook these on the grill without them falling apart?
Yes, but chill the shaped patties in the fridge for at least 30 minutes first so they’re firm. Use a well-oiled grill grate and a wide spatula, and don’t move them until they release cleanly — about 5 minutes per side.
Is there a substitute for flaxseed if I don’t have any?
Chia seeds ground to a coarse meal work the same way — use the same amount. A tablespoon of tahini or nut butter stirred into the mix also adds some binding, though it’s less effective than flax.
Can I use regular potato instead of sweet potato?
Yes. Russet or Yukon Gold potato works as a direct swap by volume. The patties will be slightly less sweet and lose a little of the orange color, but the texture and binding are essentially the same.
How do I know when the patties are done in the oven?
They’re done when the outside feels firm and dry to the touch and the edges look set — about 15 minutes at 350°F after the pan-fry. There’s no food-safety concern with an internal temperature target here since these are fully plant-based, so firmness is your reliable cue.
