You’ve probably been there. You buy a block of extra-firm tofu, chop it up, toss it in a pan with some high hopes, and end up with a pile of beige, rubbery cubes that taste like nothing. It’s frustrating. Most people blame the tofu itself, but the reality is simpler and a bit more annoying: you didn't get the water out. Tofu is basically a sponge. If that sponge is full of water, there’s no room for marinade to get in, and there’s absolutely no way you’re getting a golden-brown crust. You’re just boiling it from the inside out.
Learning how to drain tofu isn't just a "nice to do" step. It’s the difference between a sad desk lunch and something you actually want to eat.
The Science of the Squeeze
Why does it even matter? Tofu is made by curdling soy milk and pressing the curds into blocks. Because it’s stored in water to keep it fresh, those little protein pockets are saturated. If you jump straight to frying, that water turns to steam. Steam is the enemy of the Maillard reaction—that chemical process where sugars and proteins flip out under heat to create flavor and crunch. If you don't drain it, you're basically steaming your dinner.
Honestly, even "extra-firm" varieties are deceptive. You open the package, think it feels solid, and move on. Big mistake. According to food scientists like J. Kenji López-Alt, who has spent an absurd amount of time testing bean curd physics, removing surface and internal moisture is the only way to ensure the fat in your pan actually browns the protein instead of just sputtering angrily at it.
Why the "Press" is a Lie for Soft Tofu
Before we get into the heavy lifting, let's be clear about one thing. Do not try to press silken or soft tofu. You will end up with a puddle of soy mush. Those varieties are held together by a delicate network of proteins that can’t handle pressure. If you're making a smoothie or a chocolate mousse, you just want to drain the excess liquid from the box. That’s it. For everything else—the stir-fries, the air-fryer nuggets, the grilled steaks—you need to get aggressive.
The Classic DIY Method (The "Tower of Terror")
Most of us start here. It’s the low-tech way to handle your how to drain tofu needs without buying more kitchen gadgets you don't have room for.
First, slice the block. People often try to press the whole brick at once. Don't do that. If you slice it into three or four slabs first, you increase the surface area. More surface area means more exit points for the water. Lay those slabs out on a clean lint-free tea towel or a thick layer of paper towels. Avoid the cheap paper towels that disintegrate; picking tiny white flecks off your dinner is a special kind of hell.

Then, you build the stack. Put another layer of towels on top. Find a flat surface, like a baking sheet or a large plate, and set it on top of the tofu. Now, find the weight. A heavy cast-iron skillet is the gold standard here. If you don't have one, use a couple of big cans of tomatoes or a heavy cookbook. Just make sure it’s balanced. I’ve seen many a "tofu tower" slide across the counter in a slow-motion disaster. Let it sit for at least 30 minutes. If you’re in a rush, 15 will do, but you’ll see the difference if you wait.
The Microwave Shortcut
Nobody talks about this, but it works. If you’re starving and can’t wait 30 minutes, wrap your sliced tofu in paper towels and microwave it for about 60 to 90 seconds. The heat causes the protein structures to contract, literally squeezing the water out. It's a bit of a hack, and it changes the texture slightly—making it a little chewier—but for a quick weeknight meal, it’s a lifesaver. Just be careful not to overdo it, or you’ll end up with soy jerky.
The Tofu Press: Is It Worth the Cabinet Space?
If you eat tofu more than once a week, just buy a press. I used to be a skeptic, thinking it was a "unitasker" that Alton Brown would hate. I was wrong. Dedicated presses like the EZ Tofu Press or the Tofuture box apply consistent, even pressure that you just can't get with a stack of cookbooks.
The Tofuture style is great because it’s a self-contained box. It catches the water so your counter doesn't become a swamp. You just pop the block in, hook the silicone bands, and put it in the fridge. You can even do this the night before. By the time you’re ready to cook, that block is dense, meaty, and ready to soak up every drop of soy sauce or ginger oil you throw at it.
The Freezer Trick for "Meaty" Texture
This is the "pro move" that transforms the texture entirely. If you want tofu that tastes like it came from a high-end vegan restaurant, you have to freeze it.
Here is the workflow:
- Drain the water out of the package.
- Put the whole block in a freezer bag and freeze it solid.
- Thaw it in the fridge the next day.
- Squeeze it out like a sponge.
When water freezes, it expands into ice crystals. These crystals poke holes in the tofu's cellular structure. When the ice melts, it leaves behind a porous, honeycombed interior. When you learn how to drain tofu using the freeze-thaw method, you aren't just removing water; you're creating a literal sponge that can hold way more sauce than fresh tofu ever could. It also becomes much firmer and heartier, almost like a chicken cutlet.
Salt Water Soaking: The Counter-Intuitive Secret
This sounds fake, but it's pure chemistry. Some chefs, including the team over at America's Test Kitchen, swear by pouring boiling salted water over your sliced tofu slabs before you press or cook them.
The hot water helps tighten the protein on the surface, while the salt draws out internal moisture through osmosis. Let them soak for about 15 minutes, then pat them dry. The result is a surface that crisps up almost instantly in a hot pan. It sounds like adding water to a problem of too much water, but the thermal shock actually works in your favor.
Common Mistakes to Avoid
Most people quit too early. If the paper towel isn't soaked, you haven't pressed hard enough or long enough. Another big one is the "unwashed towel" mistake. If you use a tea towel that was washed with heavily scented fabric softener, your tofu is going to taste like "Spring Meadow." Use paper towels or towels washed in fragrance-free detergent.
Also, don't press it so hard that the block cracks and crumbles—unless you're making a scramble. You want firm pressure, not total destruction.
Dealing with the Aftermath
Once you've mastered how to drain tofu, you have to handle it correctly. Don't let it sit out at room temperature for hours while it's pressing. If you're doing a long press (over 30 minutes), do it in the fridge. Tofu is high in protein and moisture, making it a playground for bacteria if it sits in the "danger zone" for too long.
Final Steps for Maximum Flavor
After the water is gone, you have a window of opportunity. This is when you marinate. Without the water blocking the way, your marinade will actually penetrate the core of the tofu.
Don't use oil-based marinades yet. Oil will coat the outside and prevent water-based flavors (like soy sauce, citrus, or vinegar) from getting in. Use a water-based marinade first for 20 minutes, then hit it with a bit of cornstarch or arrowroot powder right before frying. That starch combines with the remaining surface moisture to create a thin, crackling crust that stays crispy even after you toss it in sauce.
Your Actionable Checklist
- Check the type: Only press Firm or Extra-Firm. Leave Silken alone.
- Slice first: Create more surface area by cutting the block into slabs or cubes before you press.
- Pick your method: Use the "Tower of Terror" for 30 minutes, a dedicated press for 15, or the microwave for 90 seconds if you're in a rush.
- Try the freezer: For a "meaty" texture, freeze and thaw the block before squeezing.
- Salt it: Consider a quick soak in boiling salted water to prime the surface for browning.
- Starch it up: Dust the drained pieces in cornstarch before they hit the pan.
Stop settling for soggy tofu. Get the water out, get the flavor in, and give it enough heat to actually do its thing. It’s a simple change, but it’s the only one that really matters.
