This is a baked veggie burger built on black beans and cooked quinoa, with corn, bell pepper, sweet onion, sherry vinegar, and nutritional yeast holding the whole thing together. It comes in at 301 calories and 14 grams of protein per patty, which makes it a genuinely filling meal rather than a side dish with a bun. If you want a plant-based burger that actually keeps you full, this one earns its place in the rotation.
The short version of why this works
Two things make or break this patty. First, the quinoa needs to be fully cooked and then rested uncovered — that extra 10 minutes off the heat lets surface moisture escape, so the quinoa adds structure instead of steam. Second, the flax egg needs time to gel before it goes into the mix; pull it from the fridge too early and it won’t bind properly, and the patties will fall apart on the spatula. Everything else — the sherry vinegar for brightness, the nutritional yeast for depth — is seasoning. Get the moisture right and the patty holds together and browns on the outside instead of steaming into mush.
Common problems and fixes
- Patties spread flat in the oven: The mix was too wet going in. Drain and rinse the black beans thoroughly, then spread them on a clean towel and press out extra moisture before mashing. Even a couple of tablespoons of extra liquid will make the patties pancake out.
- Bland flavor all the way through: Season the mix before shaping, not after. Taste the combined mixture and adjust salt, pepper, and garlic before it goes on the sheet pan — once baked, you can only season the surface.
- Patties stick even on parchment: Use parchment and a light spray of oil on top of it. Parchment alone can still grip if the patties are wet; the oil layer lets them release cleanly when you flip at the halfway mark.
- Dry, crumbly texture after baking: Skip adding extra flour to tighten a loose mix — it dries the patty out fast. Instead, refrigerate the shaped patties for 20 minutes before baking; chilling firms them without making them chalky.
- Corn releasing too much liquid: If using frozen corn, thaw it completely and pat it dry before adding it to the bowl. Frozen corn holds a surprising amount of water that goes straight into your mix.
Leftovers and meal prep
Cooked patties keep in an airtight container in the fridge for up to 4 days. To reheat, use a dry skillet over medium heat for 3 to 4 minutes per side — this brings back some of the exterior crust that the oven created. The microwave works in a pinch but softens the outside. For freezing, let the patties cool completely, then stack them with parchment squares between each one and seal in a freezer bag; they hold well for up to 2 months. Reheat from frozen in a 375°F oven for about 20 minutes, flipping once. You can also shape and freeze the raw patties before baking — just add 5 to 10 minutes to the bake time straight from frozen.
Quinoa Black Bean Burger (Baked, 301 Cal)
Equipment
- Large baking sheet
- parchment paper
- Medium saucepan with lid
- Large mixing bowl
- Potato masher or fork
- Silicone spatula
- Cooling rack
Ingredients
- 1 tablespoon ground flaxseed 7g
- 3 tablespoons water 45ml, for the flax egg
- ½ cup quinoa 85g
- 1 cup water 240ml, for cooking the quinoa
- 1 teaspoon granulated garlic
- ½ large sweet onion finely diced
- ½ medium red bell pepper finely diced
- ½ cup corn 80g, frozen or fresh
- 1 can black beans 15 oz / 425g, rinsed and drained
- 2 tablespoons sherry vinegar 30ml
- 1 tablespoon nutritional yeast 5g
- ⅔ cup whole wheat pastry flour 80g
- 1 pinch salt to taste
- 1 pinch freshly ground black pepper to taste
Instructions
- Make the flax egg: Whisk together 1 tablespoon of ground flaxseed and 3 tablespoons of water in a small bowl. Refrigerate for at least 10 minutes to let it thicken and gel — this is your binder.1 tablespoon ground flaxseed, 3 tablespoons water
- Next, rinse the quinoa well, then bring to a boil in the water with the granulated garlic and a pinch of salt. Once it boils, lower the heat to low and cover for 15 minutes. When the 15 minutes is up, remove from heat, uncover, and let stand for 10 more minutes.1/2 cup quinoa, 1 cup water, 1 teaspoon granulated garlic, 1 pinch salt
- While the quinoa is cooking, mash the black beans and dice the bell pepper and onion. In a large mixing bowl, combine the mashed black beans, diced bell pepper, diced onion, corn, cooked quinoa, sherry vinegar, nutritional yeast, whole wheat pastry flour, salt and pepper, and the flax egg from the fridge. Mix until evenly combined.1/2 large sweet onion, 1/2 medium red bell pepper, 1/2 cup corn, 1 can black beans, 2 tablespoons sherry vinegar, 1 tablespoon nutritional yeast, 2/3 cup whole wheat pastry flour, 1 pinch salt, 1 tablespoon ground flaxseed, 3 tablespoons water, 1/2 cup quinoa
- Shape into 4 large patties and place on a cookie sheet that has been greased or covered in parchment paper. The mixture will seem goopy, but they firm up nicely in the oven, so don’t worry.
- Bake at 375°F / 190°C (170°C fan-forced) for 40 minutes, flipping once halfway through at the 20-minute mark. The patties are done when the outside is firm and lightly browned. Remove from the oven and let rest for 5 minutes before serving.

Common questions
Can I cook these on the stovetop instead of baking them?
Yes, a cast-iron or non-stick skillet works well. Cook over medium heat with a thin layer of oil for about 5 minutes per side, pressing gently once after flipping — the direct heat gives you a better crust than the oven does, though the patties are slightly more fragile to handle before they set.
What can I use instead of pastry flour?
All-purpose flour works as a straight swap at the same quantity. Oat flour also works and keeps the recipe gluten-free if your oats are certified GF — use the same two-thirds cup measure.
Do I have to use sherry vinegar, or can I substitute something else?
Red wine vinegar is the closest substitute and works at the same one-tablespoon amount. Apple cider vinegar is a reasonable backup, though it adds a slightly sweeter note — either way, don’t skip the acid entirely, since it’s doing real work seasoning the beans and keeping the overall flavor from tasting flat.
