WHY MAKE IT
A little comfort, a lot of flavor.
Air Fryer Crispy Rice Squares with Spicy Tuna offer an appealing contrast of temperatures and textures. By pressing seasoned short-grain sushi rice into a firm slab and chilling it thoroughly, you create a sturdy foundation that crisps evenly in the air fryer without the mess of deep-frying in pools of oil. The hot, brittle exterior shields a tender, chewy grain interior. Piled high with chilled minced tuna that has been folded with creamy halal mayonnaise, savory soy sauce, and bright sriracha, every piece delivers balanced richness and crunch. Thin jalapeño coins and scallions add clean peppery notes that cut through the richness of the fish and crisped rice.
Selecting and Preparing Tuna
Using pristine fish is critical when preparing chilled tuna toppings. Purchase fresh, high-grade yellowfin or bigeye tuna from a trusted fishmonger and keep it thoroughly chilled until assembly. When trimming, remove any connective sinew or dark bloodline to maintain a clean flavor and uniform texture. Hand-mincing the fish with a sharp chef's knife rather than processing it in a machine yields defined, velvety cubes that absorb the spicy mayonnaise dressing without turning pasty or unpleasantly mushy. Always mix the fish filling immediately before serving onto the warm rice.
Achieving Maximum Rice Crispness
The structural integrity of the rice square depends on starch gelatinization and mechanical pressure. Short-grain sushi rice contains the right amylopectin content to fuse grains together when pressed into a pan. Chilling the pressed rice block for a full two hours allows the starch matrix to set completely, ensuring clean cuts. In the air fryer, a thin coating of neutral oil promotes high-heat contact, quickly evaporating surface moisture so that exterior grains blister and harden into a rigid shell while the interior remains soft and moist.
Assembly and Temperature Contrast
A successful crispy rice dish relies on the juxtaposition of sizzling, crunchy rice against cool, luscious seafood. Once the squares finish air-frying, let them stand for just two minutes so they stabilize without losing thermal heat. Spoon the cold tuna mixture directly onto the hot squares and serve immediately. If left assembled too long, the dressing will soften the delicate crust. Adding sliced fresh jalapeños provides an immediate bite that complements the nutty toasted sesame oil folded into the tuna.
Before you start
Firm compression during the chilling stage prevents the rice grains from separating inside the air fryer. Line your pan with parchment paper that overhangs the sides so you can lift the entire block cleanly onto the cutting board. Dipping your chef's knife into cold water between cuts lubricates the blade, producing crisp, sharp edges. If your air fryer basket runs small, fry the squares in two batches rather than crowding them, as circulating dry heat is critical for achieving a glassy exterior crunch.
THE RECIPE
Air Fryer Crispy Rice Squares with Spicy Tuna
4 servings · 25 minutes preparation · 55 minutes cooking · 120 minutes cooling, chilling or resting
Ingredients
Step-by-step instructions
- Rinse 2 cups of sushi rice in a fine-mesh sieve under cold running water until the runoff clears, drain thoroughly, and combine with 2 1/4 cups water in a medium saucepan over medium-high heat.
- Bring the rice to a full boil, cover tightly with a lid, reduce heat to low, and simmer undisturbed for 15 minutes before removing from heat to rest covered for 10 minutes.
- Transfer the warm rice to a wide glass bowl, gently fold in 3 tablespoons rice vinegar, 1 1/2 tablespoons sugar, and 1/2 teaspoon salt using a silicone spatula, then press firmly into an even 1-inch layer inside a parchment-lined 8-inch square baking dish.
- Cover the pressed rice surface directly with plastic wrap and chill in the refrigerator for 2 hours until cold, dense, and firm enough to slice cleanly without crumbling.
- Turn the chilled rice block onto a cutting board, use a sharp chef's knife dipped in water to cut into 16 equal 2-inch squares, and brush all exposed sides with 2 tablespoons neutral vegetable oil.
- Preheat the air fryer to 400 F (204 C), place the rice squares in the basket in a single layer with space between each piece, and air-fry for 18 to 20 minutes, flipping at the 10-minute mark, until all sides are blistered and deep golden brown. Work in batches as needed and check that the rice centers reach 165 F (74 C).
- Combine 10 ounces drained, fully cooked canned tuna, 3 tablespoons halal mayonnaise, 1 tablespoon sriracha, 1 teaspoon toasted sesame oil, 1 tablespoon soy sauce, and remaining 1/2 teaspoon salt in a bowl, stirring gently until thoroughly emulsified.
- Arrange the hot crispy rice squares on a platter, spoon 1 rounded tablespoon of the cold spicy tuna mixture onto each square, and garnish each piece with a jalapeño round, sliced scallions, and toasted sesame seeds.

Storage & make-ahead
Store leftover cooked rice squares separate from dressed tuna. Place cooled plain rice squares in an airtight container in the refrigerator for up to 2 days; reheat in a 375 F (190 C) air fryer for 4 to 6 minutes to restore crispness. Chilled tuna mixture must be kept refrigerated in an airtight container and consumed within 24 hours of preparation. Refrigerate perishable leftovers within 2 hours of preparation (within 1 hour in temperatures above 90 F / 32 C).

Frequently asked questions
Can I use medium or long-grain rice for these squares?
Short-grain sushi rice is necessary for this recipe. Long-grain varieties such as jasmine or basmati lack the sticky amylopectin starches required to bind the grains into a solid block, causing the squares to fall apart during cutting and air-frying.
How do I prevent the rice squares from sticking to the air fryer basket?
Ensure you coat all sides of the cut rice squares thoroughly with the neutral vegetable oil. Preheating the air fryer basket beforehand also sets the surface instantly, preventing the moist grains from bonding to the metal grate.
Can I make the rice base a day in advance?
Yes, the pressed rice block can be prepared and kept covered in the refrigerator for up to 24 hours before slicing. Keep it tightly wrapped in plastic wrap so the grains do not dry out excessively before frying.
