These patties are built from cooked quinoa, kidney beans, zucchini, mushrooms, carrot, and sunflower seeds — held together with psyllium husk, oats, breadcrumbs, and egg white. They cook up firm and golden in about 30 minutes total. The honest reason to make them: the ingredient list is flexible enough to work with whatever produce and pantry staples you already have on hand.
The short version of why this works
Two things keep these patties from falling apart on the pan. First, psyllium husk acts as a binder that absorbs moisture and firms up the mixture — it does more structural work here than the breadcrumbs or flour do. Second, pulsing the vegetables in a food processor rather than chopping them by hand breaks them down to a consistent texture, which means no large wet chunks that would create soft spots in the patty. Get those two things right and the flour adjustment the recipe mentions becomes much easier to judge.
Substitutions that actually work
- Psyllium husk: Ground flaxseed or chia seeds work as a substitute — use the same 2-tablespoon quantity. Both absorb liquid and bind similarly, though the patties may be slightly softer.
- Kidney beans: Any cooked canned bean works — black beans, chickpeas, or white beans. Drain and rinse well regardless of which you use.
- Quick oats: Rolled oats are fine. Pulse them a few times in the food processor first so they blend into the mixture rather than sitting as visible flakes.
- Sunflower seeds: Pumpkin seeds or chopped walnuts are direct swaps. Both add a similar texture contrast.
- Fresh basil: A teaspoon of dried basil works, or swap in fresh parsley if that’s what you have.
- Egg white: Two tablespoons of aquafaba (the liquid from a can of chickpeas) per egg white is a reliable plant-based substitute here.
Leftovers and meal prep
Cooked patties keep in the fridge for up to 4 days in an airtight container. For longer storage, freeze them in a single layer on a baking sheet until solid, then transfer to a freezer bag — they’ll hold well for up to 3 months. Reheat straight from frozen in a dry skillet over medium heat for about 4 minutes per side, or in a 375°F oven for 15 minutes. The uncooked mixture can also be shaped into patties and frozen raw; thaw overnight in the fridge before cooking.
Common problems and fixes
- Patties spread flat in the pan: The mixture is too wet. Press it into a tighter shape before cooking and chill the formed patties in the fridge for 20 minutes — cold patties hold their shape much better on a hot pan.
- Mixture won’t come together at all: Your vegetables released more water than expected during processing. Add flour one tablespoon at a time and let it sit for two minutes between additions so the psyllium husk has time to absorb the moisture before you judge the consistency.
- Patties are dense and gummy inside: Skip the egg in the mix — it makes the patty mushy. The psyllium husk and egg white together are already doing the binding work.
- Outside burns before the inside cooks through: Medium-high heat is the upper limit. If the crust is browning in under 3 minutes, drop to medium and add a minute or two to each side.
- Patties stick to the pan: A light spray of oil isn’t always enough on a stainless or cast iron pan. Let the pan fully preheat before adding the patties, and don’t try to flip them early — they release naturally once a proper crust forms.
Sunflower Quinoa Veggie Burgers (Crispy & Freezer-Friendly)
Equipment
- Food processor
- Large mixing bowl
- Flat non-stick skillet or griddle
- Baking sheet (for freezing)
- Measuring cups and spoons
- Silicone spatula
Ingredients
- 1 medium zucchini approximately 200g / 7 oz
- 1 cup kidney beans cooked, 170g
- 1 medium carrot peeled and chopped
- 2 stalks green onions washed well, chopped
- 7 small mushrooms approximately 100g / 3.5 oz, roughly chopped
- 1 tablespoon flax seeds 10g
- 1 cup quinoa cooked, 185g (from about 1/3 cup / 60g dry)
- ½ cup quick oats 45g
- ¼ cup fresh basil leaves 10g, loosely packed (or frozen equivalent)
- 2 cloves garlic minced
- ¼ cup raw sunflower seeds 35g
- 2 tablespoons psyllium husk powder 12g
- ¼ cup breadcrumbs homemade, 30g
- ¼ cup spelt flour 30g (or all-purpose flour)
- ½ cup liquid egg whites 120ml, approximately 4 large egg whites
- 1 teaspoon sea salt adjust to taste
- ½ teaspoon black pepper freshly ground, adjust to taste
- ¼ teaspoon chili flakes adjust to taste
- ¼ teaspoon cayenne pepper adjust to taste
- ¼ teaspoon chili powder adjust to taste
- 1 tablespoon olive oil spray for cooking
Instructions
- Add the zucchini, kidney beans, carrot, green onions, mushrooms, flax seeds, cooked quinoa, quick oats, basil, and garlic to a food processor. Pulse 10-15 times until the vegetables are finely chopped but not pureed — you want some texture. If your food processor is small, work in two batches and combine in a large mixing bowl.1 medium zucchini, 1 cup kidney beans, 1 medium carrot, 2 stalks green onions, 7 small mushrooms, 1 tablespoon flax seeds, 1 cup quinoa, 1/2 cup quick oats, 1/4 cup fresh basil leaves, 2 cloves garlic
- Transfer the mixture to a large mixing bowl. Add the sunflower seeds, psyllium husk, breadcrumbs, salt, pepper, chili flakes, cayenne pepper, chili powder, and liquid egg whites. Stir until well combined, then let the mixture rest for 5 minutes so the psyllium husk absorbs moisture and firms the mixture.1/4 cup raw sunflower seeds, 2 tablespoons psyllium husk powder, 1/4 cup breadcrumbs, 1/2 cup liquid egg whites, 1 teaspoon sea salt, 1/2 teaspoon black pepper, 1/4 teaspoon chili flakes, 1/4 teaspoon cayenne pepper, 1/4 teaspoon chili powder
- Add the spelt flour one tablespoon at a time, stirring after each addition, until the mixture holds together when you press a small amount in your palm. It should feel like firm cookie dough — tacky but not sticky or crumbly.1/4 cup spelt flour
- Divide the mixture into 10 equal portions (about 3.5 oz / 100g each). Shape each into a patty roughly 3/4 inch (2 cm) thick and 3 inches (8 cm) wide. If the mixture sticks to your hands, wet them lightly with water.
- Spray a large flat non-stick skillet with olive oil and place over medium heat. When the oil shimmers, add patties in batches — don’t overcrowd the pan, leave at least 1 inch (2.5 cm) between each patty. Cook for 5-6 minutes on the first side without moving them, then carefully flip and cook for another 5-6 minutes until both sides are golden brown and crisp. Repeat with remaining patties, adding more oil spray between batches as needed.1 tablespoon olive oil spray
Notes

Your questions, answered
Can I use dry quinoa instead of cooked?
No — the recipe needs 1 cup of already-cooked quinoa, not dry. Dry quinoa won’t hydrate properly inside the patty mixture, and the texture will be gritty.
Do I have to use a food processor?
You can grate the zucchini and carrot and finely chop the mushrooms, onion, and garlic by hand instead. Just make sure to squeeze the grated zucchini in a clean towel first — it holds a lot of water and will throw off the flour balance if you skip that step.
Can I bake these instead of pan-frying?
Yes. Bake on a parchment-lined sheet at 375°F for about 20 minutes, flipping once halfway through. They won’t get quite as dark on the outside, but they’ll hold together well and the inside will be fully cooked.
