Easy Air-Fryer Tofu Cubes with Garlic Soy (Plant-Based Crunch)

Achieving the perfect texture with tofu is a challenge, but the air fryer is a game changer. This recipe utilizes rapid air circulation to create a “Gold Standard” shatter-crisp exterior while keeping the inside tender. From an expertise perspective, the secret is the “starch-dusting” technique. A light coating of cornstarch absorbs surface moisture and creates a thermal barrier that crunches up under high heat, mimicking deep-frying without the excess oil.

Recipe Details

Prep Time: 10 Min (plus pressing)
Cook Time: 15 Min
Total Time: 25 Min
Yield: 2 Servings
Calories: 210 kcal per serving

Ingredients:

The Crispy Tofu

1 block (14 oz) Extra-Firm Tofu (Must be extra-firm)
1 tbsp Cornstarch (or Arrowroot powder)
1 tbsp Avocado Oil
Pinch of Salt

The “Gold Standard” Garlic Soy Glaze

2 tbsp Low-Sodium Soy Sauce (or Coconut Aminos)
1 tsp Toasted Sesame Oil
2 cloves Garlic, minced
1 tsp Fresh Ginger, grated
1 tsp Rice Vinegar

Preparation Steps:

1. The Professional Press

Drain the tofu and wrap in a clean towel. Place a heavy plate on top for 10–15 minutes.
Why this matters: This is a “Gold Standard” necessity. The less water in the tofu, the crispier it will get. Once pressed, cut into 1-inch cubes.

2. The Starch Dusting

In a large bowl, toss cubes with avocado oil and salt first.
Sprinkle cornstarch over the tofu and toss gently until every cube has a light, powdery coating.

3. The Air-Fryer Crisp

Preheat air fryer to 400°F (200°C). Place tofu in the basket in a single layer (do not overcrowd).
Cook for 12–15 minutes, shaking the basket halfway through. Tofu is done when golden-brown and firm.

4. The Flavor Glaze

While tofu cooks, whisk soy sauce, sesame oil, garlic, ginger, and vinegar.
As soon as tofu comes out, toss the hot cubes in the glaze. The residual heat helps reduce the sauce and stick it to the crust.

Expert Tips:

Extra Crunch: If you want an even crispier result, spray the cubes with a tiny bit more avocado oil halfway through the cooking time when you shake the basket.
Sticking Prevention: Ensure your basket is clean and lightly greased. Even with cornstarch, extra-firm tofu can stick if the surface is completely dry.
