The First Step: Remove Excess Water
Tofu, especially the firm and extra-firm varieties ideal for frying or baking, is packed in water to keep it fresh. This water is the number one enemy of a crispy texture. Before you even think about cooking, you must press the tofu to remove as much
moisture as possible. A simple and effective method involves wrapping the block of tofu in a few paper towels or a clean kitchen towel. Place it on a plate, then put something heavy on top, like a cast-iron skillet, a few books, or some canned goods. Let it press for at least 30 minutes. You’ll be surprised how much water is released. This step is crucial because less water means the tofu can fry and brown, rather than steam.
The Magic of Cornstarch
Once your tofu is pressed and cut into your desired shape—cubes, slabs, or triangles—the next secret weapon is cornstarch. Tossing the pieces in a light coating of cornstarch before they hit the pan creates a thin, dry layer on the surface. This coating does two things: it absorbs any residual surface moisture, and it creates a crust that turns wonderfully crisp when cooked in hot oil. To coat, you can place the tofu and a few tablespoons of cornstarch in a bowl or a bag and gently toss until every piece has a fine, powdery layer. Don't overdo it; a light dusting is all you need for that signature crunch.
Cooking Method Matters
You have several options for cooking your coated tofu, each with its own benefits. Pan-frying is the classic method. Heat a neutral oil with a high smoke point (like canola or avocado oil) in a skillet over medium-high heat. Add the tofu in a single layer, ensuring not to overcrowd the pan, and cook for several minutes on each side until golden brown and crisp. For a more hands-off approach, baking or air frying are excellent alternatives. When baking, spread the tofu on a parchment-lined sheet, and you might want to add a little oil to help it brown. An air fryer will also yield fantastic results, often in less time and with less oil, giving you that coveted crispy exterior.
The Final, Crucial Step: Add to Sauce Last
This is where the headline's wisdom truly shines. You've worked hard to create perfectly crispy tofu; the last thing you want is to make it soggy by drowning it in sauce too early. If you're making a stir-fry or a saucy dish, always cook the tofu separately first. Set it aside while you prepare your vegetables and sauce in the same pan. Once the sauce is complete and just before serving, turn off the heat and gently fold the crispy tofu back in. This method allows the tofu to get coated in flavour without sitting in liquid long enough to lose its hard-won texture. The result is a dish with delightful textural contrast—a crispy bite of tofu enveloped in a delicious sauce.
