These are pan-fried, oven-finished patties made from shredded zucchini, cooked quinoa, panko, parmesan, and a handful of pantry staples. The whole thing comes together in 35 minutes and makes six solid patties. If you have leftover cooked quinoa sitting in the fridge, this is exactly the right use for it.
The technique that matters
Moisture is the enemy here. Zucchini holds a surprising amount of water, and if you skip the salting-and-draining step, your patties will fall apart in the pan — no matter how much panko you add. Salt the shredded zucchini, let it sit in a colander, then squeeze it firmly in a clean kitchen towel or a few layers of paper towel before it goes into the bowl. The second thing that matters is the two-stage cook: a quick pan sear on medium-high heat sets a crust on both sides, then 15 minutes in a 400°F oven firms the interior all the way through without burning the outside. Skipping the oven finish leaves you with patties that are browned on the surface but soft and loose in the middle.
What can go wrong
- Patties crumble when you flip them: The zucchini wasn’t dry enough, or the pan wasn’t hot before you added the oil. Let the oil shimmer before the patties go in, and don’t move them until the crust releases naturally — usually 3 to 4 minutes.
- Mix is too wet to shape: Different zucchini varieties and sizes release different amounts of water. If the mixture won’t hold a ball, stir in an extra tablespoon or two of panko and let it sit for two minutes before trying again.
- Patties taste flat: Quinoa absorbs seasoning, so under-seasoned quinoa drags the whole patty down. Taste the mixture before you shape it and adjust salt and pepper at that point — it’s too late once they’re in the pan.
- Lemon flavor disappears after baking: Zest holds up to heat better than juice. If you want a brighter finish, add a small squeeze of fresh lemon juice right before serving rather than relying only on what’s baked in.
- Patties stick to the baking sheet: Line it with parchment or give it a light coat of oil. These patties have less fat than a meat burger and will bond to a bare pan.
Keeping and reheating
Cooked patties keep in an airtight container in the fridge for up to four days. To reheat, put them on a baking sheet in a 375°F oven for about 10 minutes, flipping once — this brings back some of the crust that a microwave kills. For freezing, let the patties cool completely, then freeze them in a single layer on a sheet pan before transferring to a freezer bag; they’ll keep for up to two months. Reheat from frozen at 375°F for 18 to 20 minutes, flipping halfway. The uncooked mixture does not freeze well — the zucchini releases more water on thawing and the patties won’t hold together.
Crispy Zucchini Quinoa Patties (Pan-Seared & Oven-Finished)
Equipment
- Box grater or large-hole grater
- 10-inch non-stick or cast-iron skillet
- Rimmed baking sheet
- Large mixing bowl
- Clean kitchen towel (for squeezing zucchini)
- Colander
Ingredients
- 2 cups zucchini shredded, salted and moisture squeezed out, about 250g
- 2 cups quinoa cooked, 370g
- 1 large egg
- 2 teaspoons garlic powder 5g
- ½ medium green bell pepper diced, about 75g
- 1 cup panko breadcrumbs 60g
- ½ cup parmesan cheese grated, 50g
- 1 medium lemon, zested
- ½ medium lemon, juiced about 1 tablespoon / 15ml
- ½ teaspoon salt
- ½ teaspoon ground black pepper
- 2 teaspoons olive oil plus more for frying, 10ml
- 1 cup yogurt sauce for serving (optional)
Instructions
- Grate the zucchini using a box grater. Sprinkle with 1/4 teaspoon of salt to help absorb moisture. Let the zucchini sit in a colander for 10-15 minutes to drain, then squeeze firmly in a clean kitchen towel until very little liquid comes out.2 cups zucchini, 1/2 teaspoon salt
- Heat 2 teaspoons olive oil in a 10-inch skillet over medium heat. Add the diced green bell pepper and cook, stirring occasionally, for 3–4 minutes until softened. Remove from heat and set aside.2 teaspoons olive oil, 1/2 medium green bell pepper
- In a large bowl, combine the panko breadcrumbs, parmesan cheese, lemon zest, garlic powder, salt, and black pepper. Add the lemon juice, cooked quinoa, and sautéed bell pepper. Stir to combine. Add the egg and squeezed zucchini, then mix until everything is evenly incorporated.1 cup panko breadcrumbs, 1/2 cup parmesan cheese, 1 medium lemon, zested, 2 teaspoons garlic powder, 1/2 teaspoon salt, 1/2 teaspoon ground black pepper, 1/2 medium lemon, juiced, 2 cups quinoa, 1/2 medium green bell pepper, 1 large egg, 2 cups zucchini
- Preheat the oven to 400°F / 205°C (200°C fan-forced).
- Heat olive oil (just enough to coat the surface) in the same skillet you used for the peppers over medium-high heat. Roll the zucchini mixture into balls and then flatten between your palms to about 3/4-inch / 2cm thickness. Place the patties into the skillet and cook until lightly browned on both sides. Remove from pan and place on a rimmed baking sheet.2 teaspoons olive oil
- Once all patties have been seared, transfer the baking sheet to the oven and bake for 15 minutes, flipping the patties halfway through.
- Remove the patties from the oven and let rest for 2–3 minutes. Serve with chilled yogurt sauce if desired.1 cup yogurt sauce

Common questions
Can I use a different grain instead of quinoa?
Yes — cooked brown rice or farro work well as straight swaps by volume. Both bind similarly to quinoa in this mixture, though farro gives a slightly chewier texture; just make sure whatever grain you use is fully cooked and not waterlogged before it goes into the bowl.
Can I skip the parmesan or swap it for something else?
Nutritional yeast is the most practical substitute — use about three tablespoons in place of the half cup of parmesan. It won’t melt the same way, but it adds a savory depth and keeps the patties dairy-free; skip the egg in the mix if you also want them vegan, and add an extra tablespoon of panko to compensate for binding.
Do I have to use panko, or will regular breadcrumbs work?
Regular breadcrumbs work fine and are a direct swap by volume. Panko gives a slightly lighter texture inside the patty, but standard breadcrumbs — including seasoned ones you already have open — hold the mixture together just as well and won’t change the cook time.
