Steps

Before you start

Cook quinoa ahead if not already prepared (cook 1 cup dry quinoa according to package directions, cool completely before mixing)
Have all filling ingredients measured and ready to assemble
Preheat a 12-inch (30 cm) nonstick skillet over medium heat for 2 minutes before starting to pan-fry

1
Prepare tomato sauce
- Warm 1 tablespoon olive oil in a small saucepan over medium heat.
- Add 2 minced garlic cloves and sauté for 30 seconds until fragrant.
- Pour in 1 can (15 oz / 425 g) crushed tomatoes, add 0.5 teaspoon salt, and stir well.
- Simmer uncovered over low heat while you prepare the patties and slaw, stirring occasionally.
- The sauce should be warm and slightly reduced by serving time.

Ready when: Sauce is warm and slightly thickened, with small bubbles breaking the surface
Tip: Start the sauce first so it's ready to serve when the patties finish cooking.
2
Make curtido slaw
- In a large bowl, combine 3 cups shredded green cabbage, 0.5 cup shredded carrots, and 1 sliced jalapeño (seeds removed for less heat).
- In a small bowl, whisk together 0.33 cup white vinegar, 0.33 cup water, and 1 teaspoon salt until the salt dissolves.
- Pour the vinegar mixture over the vegetables and toss well to coat.
- Let sit for at least 10 minutes before serving, stirring occasionally so the vegetables pickle evenly.

Ready when: Cabbage is wilted and pickled, vegetables are coated in brine
Tip: The curtido can be made up to a day ahead and stored in the refrigerator; it actually improves as it sits.
3
Mix patty base
- In a large bowl, combine 2 cups cooled cooked quinoa, 0.5 cup masa flour, 1 large egg, 0.25 cup warm water, 0.75 teaspoon salt, and 0.5 teaspoon ground cumin.
- Stir until everything is evenly mixed.
- The mixture should hold together when squeezed but not be overly wet.
- If it feels too crumbly, add a little more warm water, 1 tablespoon at a time.
- Let the mixture rest for 5 minutes so the masa flour hydrates fully.

Ready when: Mixture is cohesive, holds together when squeezed, and absorbs liquid evenly
Tip: Using cooled quinoa is essential; warm quinoa will make the patties mushy and fall apart during cooking.
4
Shape patties with filling
- Dampen your hands with water to prevent sticking.
- Divide the quinoa mixture into 8 equal portions (about 2.5 oz / 70 g each).
- Take one portion and flatten it into a thin disc in your palm.
- Place about 1.5 teaspoons of warm refried beans and 1.5 teaspoons of shredded quesillo cheese in the center.
- Fold the edges up and over the filling, gently press to seal, then flatten into a patty about 0.5 inch (1.25 cm) thick and 3 inches (7.5 cm) in diameter.
- Place on a parchment-lined plate and repeat with the remaining portions.

Ready when: All 8 patties are shaped, filled, sealed, and consistent in thickness
Tip: Wet hands prevent the mixture from sticking and make shaping much easier. Don't overfill; too much cheese and beans will burst out during cooking.
5
Pan-fry first batch
- Heat 1.5 tablespoons neutral oil in a 12-inch nonstick skillet over medium heat for 1 minute until shimmering.
- Carefully place 4 patties in the pan, leaving 1 inch (2.5 cm) between each.
- Cook for 3–4 minutes without moving them until the bottom is golden brown and crispy.
- Flip and cook the other side for another 3–4 minutes until golden and the cheese is melted inside (you'll see slight leakage at the edges if cooked through).
- Transfer to a plate lined with paper towels.

Ready when: Both sides are golden brown, crispy, and cheese is melted at the edges
Tip: Don't move the patties while they cook; let them develop a golden crust. If the heat is too high, the outside browns before the inside heats through; if too low, they'll absorb too much oil and become greasy.
6
Pan-fry second batch
- Add the remaining 1.5 tablespoons oil to the skillet and heat for 30 seconds.
- Place the remaining 4 patties in the pan and cook for 3–4 minutes per side until golden and crispy, just as you did with the first batch.
- Transfer to the plate with the first batch.

Ready when: Both sides are golden brown and crispy with melted cheese at the edges
Tip: Cooking in two batches ensures each patty gets enough space for even browning and crisping.
7
Serve with toppings
- Arrange 2 warm patties on each of 4 serving plates.
- Top or serve alongside 0.5 cup warm curtido slaw and 0.5 cup warm tomato sauce per plate.
- Serve immediately while the patties are still hot and crispy.

Ready when: Patties are warm and assembled with toppings
Tip: Serve immediately to enjoy the patties at their crispiest. The warm sauce and slaw complement the warm patties perfectly.

Tips

For a protein boost, stir 0.25 cup cooked lentils into the quinoa-masa mixture before shaping the patties.
If quesillo or mozzarella doesn't melt quickly enough in your pan, cover the skillet with a lid for 1 minute after flipping to trap steam and speed up melting.
The patties are crispy on the outside and creamy on the inside; serve them warm and eat soon after cooking for the best contrast in textures.
For a Salvadoran-style meal, serve with warm pupusa dipping sauce (refried beans thinned with water and chicken broth, seasoned with garlic and cumin).

Make ahead

Quinoa can be cooked up to 2 days ahead and refrigerated. The curtido slaw can be made up to 1 day ahead and actually improves as it sits. The patties are best assembled and fried fresh, but the quinoa-masa mixture can be prepared up to 2 hours ahead and kept in the refrigerator; shape and cook just before serving.

Storage & reheating

Cooked patties keep in an airtight container in the refrigerator for up to 3 days. Reheat on a skillet over medium heat for 2–3 minutes per side to restore crispiness, or warm in a 350°F (175°C) oven for 8–10 minutes. Curtido slaw keeps refrigerated for up to 1 week. Tomato sauce keeps refrigerated for up to 5 days or frozen for up to 2 months; thaw and warm gently before serving.

Substitutions

quesillo cheese, shredded (or mozzarella if unavailable) → fresh mozzarella, grated, or a blend of mozzarella and Oaxaca cheese. Quesillo is a Central American fresh cheese with a mild flavor; if unavailable, these substitutes melt similarly and provide a comparable creamy interior.
masa flour (corn flour for tortillas) → fine cornmeal or 0.25 cup all-purpose flour mixed with 0.25 cup cornmeal. Masa flour gives an authentic pupusa texture, but these alternatives provide structure and bind the quinoa; the texture will be slightly less traditional but still delicious.
refried black beans or pinto beans, warm → seasoned black beans or pinto beans, mashed, or a blend of 0.5 cup cooked beans with 0.25 cup melted cheese for a richer filling. Any bean you enjoy works; mashing them slightly helps them hold together during cooking.
canned crushed tomatoes → salsa roja (red salsa) or fresh tomato salsa. Salsa adds a fresher, spicier note and works beautifully with pupusa-inspired patties; adjust the salt in the salsa if it's already seasoned.
