Spirulina Cutlets (Breaded Spirulina Croquettes)

About this dish
These spirulina cutlets are a fantastic way to pack in plant-based protein and vibrant green nutrition. The earthy, umami-rich spirulina is balanced with savory mashed potatoes and a crisp panko crust, creating a satisfying croquette that even skeptics will love.
Inspired by Thai-style fried snacks, I've dialled in the seasoning to make every bite sing.

Method
Cook the potatoes
20 minutesPlace the peeled and cubed potatoes in a large pot and cover with cold water. Bring to a boil and cook until tender, about 15 minutes. Drain well and return to the pot over low heat for 1 minute to evaporate excess moisture. Mash until smooth.
Prepare the spirulina mixture
5 minutesIn a small bowl, combine the spirulina powder, soy sauce, minced garlic, nutritional yeast, salt, and pepper. Stir into the mashed potatoes until evenly distributed. The mixture should be a vibrant green. Taste and adjust seasoning if needed. Let cool slightly.
Shape the cutlets
20 minutesDivide the potato mixture into 8 equal portions. Shape each portion into a patty about 2 cm thick. Place on a baking sheet lined with parchment paper and refrigerate for 15 minutes to firm up.
Set up breading station
5 minutesPlace the flour in a shallow bowl. In another bowl, whisk the water to make a thin batter. Place the panko breadcrumbs in a third shallow bowl. Line a plate with paper towels.
Bread the cutlets
10 minutesCoat each chilled patty first in flour, shaking off excess. Dip into the water batter, then dredge in panko, pressing gently to adhere. Return to the baking sheet.
Fry the cutlets
15 minutesHeat about 1 cm of vegetable oil in a large frying pan over medium heat. When shimmering, fry the cutlets in batches without crowding, until golden brown and crisp, about 3 minutes per side. Transfer to paper towel-lined plate to drain. Serve hot with a dipping sauce of your choice.

Nutrition facts
Tips
- Chilling the patties before breading helps them hold their shape during frying.
- For a gluten-free version, use gluten-free breadcrumbs and substitute tamari for soy sauce.
- The water batter is lighter than egg wash, keeping the cutlets crisp and not greasy.
- You can double the spirulina if you crave a deeper umami punch, but start with the recommended amount to avoid bitterness.
Serving suggestions
- Serve with a sweet chili dipping sauce or a simple soy-lime dip. These cutlets also pair well with a fresh herb salad or as a side to grilled vegetables.
