Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
-
Sushi rice (short-grain rice)
-
Salt
-
Rice vinegar
-
Granulated sugar
-
Toasted sesame oil
-
Neutral oil for frying (such as vegetable or canola oil)
Directions
-
Prepare the Rice: I start by rinsing the sushi rice thoroughly until the water runs clear. Then, I cook it according to the package instructions or in a rice cooker.
-
Season the Rice: In a small bowl, I mix rice vinegar, granulated sugar, and a dash of salt until the sugar dissolves. I drizzle this mixture over the cooked rice, adding a touch of toasted sesame oil, and gently fold to combine without mashing the grains.
-
Shape and Chill: I line a small square baking pan with plastic wrap and press the seasoned rice into it, creating a block about ½ inch thick. I cover and refrigerate it for at least 3 hours, or overnight, to firm up.
-
Cut into Squares: Once chilled, I remove the rice block and cut it into bite-sized squares or rectangles.
-
Fry the Rice Squares: In a skillet, I heat about ½ inch of neutral oil over medium-high heat. I carefully add the rice squares, frying them for 1–2 minutes on each side until golden brown and crispy. I transfer them to a wire rack to drain excess oil.

-
Vegetarian Option: I add sliced avocado, cucumber, and a sprinkle of furikake for a fresh, meat-free version.
Storage/Reheating
-
Storage: I store any leftover crispy rice squares in an airtight container in the refrigerator for up to 3 days.
-
Reheating: To reheat, I pan-fry the squares again until warmed through and crispy. Alternatively, I sprinkle them with a few drops of water and microwave until heated.
FAQs
Can I use regular white rice instead of sushi rice?
I recommend using short-grain sushi rice because of its stickiness, which helps the squares hold together during frying.
How do I prevent the rice squares from falling apart?
Ensuring the rice is well-packed and thoroughly chilled before cutting and frying helps maintain their shape.
What oil is best for frying?
I use a neutral oil with a high smoke point, like vegetable or canola oil, to achieve a crispy texture without imparting additional flavors.
Can I bake the rice squares instead of frying?
While frying gives the best crispiness, I can bake them at 400°F (200°C) for about 20 minutes, flipping halfway through, for a healthier alternative.
Are these rice squares gluten-free?
Yes, as long as I use gluten-free soy sauce and ensure all other ingredients are gluten-free, these can be a gluten-free option.
Conclusion
Crispy rice squares are a versatile and delicious way for me to enjoy leftover sushi rice. Whether topped with spicy tuna, salmon, or fresh vegetables, they offer a delightful combination of textures and flavors. I love serving them as appetizers at gatherings or enjoying them as a satisfying snack.
