For crisp-edged baked tofu, use firm or extra-firm tofu, remove surface moisture, coat lightly with oil and cornstarch, and bake with space between the pieces. A 14–16 ounce block usually takes 25–35 minutes at 425°F (220°C). Add wet sauce after baking so it does not soften the coating before it has browned. Silken tofu is too delicate for this method.
Ingredients and equipment
This is an original practical recipe guide, not a claim of kitchen testing. Use the ingredient quantities as a starting batch and the doneness checks to account for your equipment.
- 1 block firm or extra-firm tofu, 14–16 ounces (400–450 g)
- 1 tablespoon soy sauce or tamari
- 1 tablespoon neutral oil
- 1 tablespoon cornstarch
- 1/2 teaspoon garlic powder
- 1/2 teaspoon smoked paprika, optional
- Optional finishing sauce: 1 tablespoon soy sauce, 1 teaspoon rice vinegar and 1 teaspoon maple syrup
Step-by-step method
1. Drain and press
Drain the tofu and wrap it in a clean towel. Place it on a plate, set a board or second plate on top, and add a moderate, stable weight. Press for 15–30 minutes while preparing the other ingredients. Do not balance a dangerously heavy pan on a small stack. Very dense vacuum-packed tofu may need only blotting; follow its package guidance.
2. Cut evenly
Heat the oven to 425°F (220°C). Cut the tofu into roughly 3/4-inch cubes, or tear it into similarly sized chunks. Torn surfaces give more irregular edges, while cubes turn neatly. Aim for comparable sizes so small fragments do not burn before the largest pieces brown. Blot again if moisture beads on the cut surfaces.
3. Season before starch
Put the pieces in a broad bowl. Add the soy sauce and oil, then fold gently with a spatula until coated. Sprinkle over the garlic powder and optional paprika. Add the cornstarch last, scattering it rather than dumping it in one spot. Toss just until there are no thick white pockets. A heavy starch layer tastes dusty instead of crisp.
4. Arrange on the tray
Spread the tofu on a lightly oiled rimmed baking sheet or oven-rated parchment. Leave visible gaps between pieces. Use two trays if necessary rather than piling the tofu. Check the parchment manufacturer’s temperature limit. A dark tray can brown the underside faster than a light metal tray, so inspect earlier if using one.
5. Bake and turn
Bake for 15 minutes, then turn the pieces with a thin spatula. If they resist lifting, give them another few minutes so a crust can form. Continue for about 10–20 minutes, checking until the edges are browned and the surface is dry. Timing varies with water content, cube size and the oven. Remove small pieces early if needed.
6. Sauce and serve
Serve immediately for the crispest edges. Drizzle with a little finishing sauce or offer sauce alongside. If tossing with sauce, use only enough to coat and eat promptly. Add tofu to a cooked stir-fry after its vegetables and sauce are finished, rather than simmering the baked cubes in liquid for several minutes.

Pick a tofu that suits the goal
Extra-firm tofu is the easiest starting point because it holds its shape during coating and turning. Firm tofu can work but may need a longer press and gentler handling. Silken tofu has a different structure and is better suited to soft dishes, sauces or desserts. Freezing and thawing firm tofu changes it into a spongier texture that absorbs marinades readily, but it is optional and produces a different bite. Do not expect every brand to release the same amount of water.
Why moisture and pan space matter
The oven first evaporates surface water before strong browning develops. When pieces touch closely, steam collects between them and slows drying. Pressing helps, but spacing is just as important. If you double the recipe, double the tray space. Rotate trays between upper and lower racks if your oven heats unevenly. A convection setting may speed browning, so follow the oven’s guidance and check earlier rather than applying the same time without looking.
Fix pale, sticking or chalky tofu
If the tofu is pale and damp, continue baking briefly with more space around the pieces. If it is dry but pale, a little more oil next time may improve browning. Sticking often improves after the first crust has set; forcing pieces too early can tear them. A chalky surface usually means excess cornstarch or uneven mixing. Do not keep adding starch until the pieces look breaded. This is a thin coating, not a thick batter.
Build a complete meal and save leftovers
Serve with cooked rice, quick-pickled cucumber and steamed greens, or add to a grain bowl with a separate dressing. Soy sauce and many finishing sauces contain substantial salt, so taste the meal before adding more. Refrigerate leftovers within two hours, or one hour above 90°F (32°C), in a shallow covered container at 40°F (4°C) or colder. Use within 3–4 days. Reheat to 165°F (74°C), preferably in an oven for a drier surface; the original crispness may not fully return.
Frequently asked questions
Can I skip the cornstarch?
Yes. The edges can still brown, but the thin crust will be less pronounced. Do not replace it with a large amount of flour, which behaves differently.
Is this gluten-free?
Only if every ingredient is suitable. Many soy sauces contain wheat. Choose labeled gluten-free tamari and check seasonings and sauces if gluten avoidance is necessary.
Can I marinate it overnight?
You can marinate tofu under refrigeration, but drain and blot it before coating. A very wet marinade slows browning, and sugary marinades can burn at this oven temperature.
