These are stovetop veggie burgers built around mashed sweet potato, cooked quinoa, and sriracha — no grill, no special equipment, done in 25 minutes. The patties are hearty enough to satisfy a serious burger craving without any meat. Four patties, one skillet, weeknight-friendly.
What makes this version work
Two things keep these patties together and actually cookable. First, the sweet potato needs to be fully soft and well-mashed — any large chunks create weak spots that crack when you flip. Second, coconut flour does real binding work here because it absorbs moisture aggressively; don’t swap it 1:1 for all-purpose flour or the mix will stay too wet to hold a patty shape. Let the formed patties sit for two or three minutes before they go into the pan — that brief rest lets the coconut flour tighten the mixture slightly, which means cleaner flips and less sticking.
Ingredient notes
- Quinoa: It must be fully cooked and cooled before mixing. Hot or warm quinoa softens the sweet potato further and makes the mix too loose to shape.
- Legumes: The recipe leaves this open. Black beans are the most practical choice — they mash slightly when you mix, which helps binding. Chickpeas stay more whole and add texture. Either works; just drain and rinse well so you’re not adding extra liquid.
- Coconut flour: Not interchangeable with almond flour or oat flour at the same quantity. If you only have oat flour, use 3 tablespoons instead of 2 and expect a slightly denser patty.
- Sriracha: Two tablespoons gives a noticeable but not aggressive heat. Cut it to one tablespoon if you’re serving kids or heat-averse eaters — skip the egg in the mix if you reduce the sriracha, since the extra moisture matters less and the egg can make the patty mushy.
Make-ahead notes
The uncooked patty mixture keeps in the fridge for up to 24 hours in a covered bowl — the coconut flour continues absorbing moisture overnight, so the mix actually shapes more easily the next day. Formed raw patties can be stacked with parchment between them and refrigerated for up to 8 hours before cooking. Cooked patties store well for 3 days in the fridge; reheat them in a dry skillet over medium heat for 2 to 3 minutes per side to get the crust back — the microwave works in a pinch but leaves them soft. For freezing, freeze cooked patties on a flat tray first, then transfer to a bag; they keep for up to 2 months and go straight from frozen into a covered skillet on medium-low for about 6 to 7 minutes per side.
If something goes sideways
- Patties fall apart in the pan: The mix is too wet. Stir in an extra half tablespoon of coconut flour, wait two minutes, then try forming again. This usually happens if the sweet potato wasn’t cooled enough before mixing.
- Patties stick hard to the skillet: The pan wasn’t hot enough before the patties went in, or you flipped too early. Let them cook the full 4 to 5 minutes undisturbed — they release naturally once a crust forms. A thin metal spatula works better than a silicone one here.
- Mixture is too dry to shape into a ball: The sweet potato was on the small side. Add one teaspoon of water at a time and mix until the patty just holds its shape without crumbling.
- Patties are cooked through but taste flat: Sweet potato absorbs seasoning heavily. Taste the raw mix before cooking and add a pinch more salt and an extra quarter teaspoon of paprika if needed — this is the only practical point to adjust seasoning.
- Patties puff and crack in the center: They were formed too thick. Aim for about three-quarters of an inch thick when you press them flat — thicker than that and the center steams rather than cooks evenly.

Equipment
- 10-inch non-stick skillet
- Large mixing bowl
- Fork (for mashing sweet potato)
- Flat spatula (for flipping patties)
- Microwave-safe plate or baking sheet (for cooking sweet potato)
Ingredients
- 1 large sweet potato approximately 12 oz / 340g
- 2 tablespoons coconut flour 14g
- 1 medium egg approximately 50g
- ½ cup quinoa cooked, 85g
- ¼ cup black beans cooked and drained, 60g
- ¼ cup sweet corn kernels fresh, frozen and thawed, or canned and drained, 40g
- 2 tablespoons sriracha 30ml
- ½ teaspoon ground coriander
- ½ teaspoon smoked paprika
- ¼ cup fresh cilantro roughly chopped, 4g
- 1 teaspoon neutral oil vegetable or coconut, for cooking
Instructions
- Pierce a large sweet potato several times with a fork. Cook the sweet potato either in the oven at 350°F / 175°C (180°C fan-forced) for 40 minutes or in the microwave on high for 7 minutes, flipping halfway through. Allow to cool until comfortable to handle, then peel off the skin. Transfer the flesh to a large bowl and mash thoroughly with a fork until smooth — no large chunks should remain, as these create weak spots that crack when flipping.1 large sweet potato
- Add the coconut flour, egg, cooked quinoa, black beans, corn, sriracha, ground coriander, smoked paprika, and chopped cilantro to the mashed sweet potato. Mix with a fork or spatula until everything is evenly combined.2 tablespoons coconut flour, 1 medium egg, 1/2 cup quinoa, 1/4 cup black beans, 1/4 cup sweet corn kernels, 2 tablespoons sriracha, 1/2 teaspoon ground coriander, 1/2 teaspoon smoked paprika, 1/4 cup fresh cilantro
- Heat 1 teaspoon of neutral oil in a 10-inch non-stick skillet over medium heat until the oil shimmers.1 teaspoon neutral oil
- Divide the mixture into 4 equal portions. Using slightly damp hands, roll each portion into a ball and flatten between your palms to form patties about ¾ inch (2cm) thick. Let them rest on a plate for 2–3 minutes before cooking — this allows the coconut flour to tighten the mixture for cleaner flips.
- Place the patties in the skillet, leaving space between them. Cook for 4–5 minutes per side, flipping carefully with a flat spatula, until golden brown and crisp on both sides. Serve immediately on toasted buns with your favourite toppings — avocado, pickled jalapeños, lime crema, or shredded lettuce all work beautifully.

Common questions
Can I bake these instead of pan-frying them?
Yes — bake on a lightly oiled sheet pan at 400°F for 20 to 25 minutes, flipping once at the halfway mark. The crust won’t be as firm as the stovetop version, but the patties hold their shape well and it’s mostly hands-off.
Can I make these without egg to keep them vegan?
You can substitute one tablespoon of ground flaxseed mixed with three tablespoons of water, rested for five minutes until gel-like. The patties will be slightly more fragile, so handle them gently when flipping and make sure the skillet is properly hot before they go in.
How do I know when the patties are done?
Look for a deep golden-brown crust on both sides and a firm center that doesn’t give when you press it lightly with a spatula. Because there’s no meat, you’re cooking for texture and temperature rather than a specific internal reading — 4 to 5 minutes per side on medium heat is reliable.
Can I use canned sweet potato instead of cooking a fresh one?
Canned sweet potato puree works, but drain it thoroughly and pat it with paper towels first — it holds significantly more water than a baked or microwaved fresh potato. Start with three-quarters of a cup of drained puree and add coconut flour a little at a time until the mix is shapeable.
