What makes tofu steak work
Tofu steak is a simple home-cooking approach: cut a block of tofu into thick pieces, brown them in a pan, and add a savory sauce. It does not need to imitate meat. The appeal is the contrast between a golden surface and a soft center, with sauce that can be spooned over both tofu and rice.
Firm tofu is the easiest choice because it holds its shape when turned. One standard block can usually be cut into two to four portions, depending on its size and what else is on the table. Have a wide spatula ready, and choose a pan that leaves a little space around each piece. Crowding makes it harder for moisture to escape and for the tofu to brown.
Drain and prepare the tofu
Pour away the packing water and pat the tofu dry. For a firmer surface, place the pieces between clean towels or paper towels, set a plate on top, and let them drain while you prepare the other ingredients. A few minutes helps; longer draining can make the tofu easier to handle. Use gentle pressure rather than a heavy weight that might crack it.
For two generous servings, gather one block of firm tofu, a handful or two of sliced mushrooms, a little neutral cooking oil, and a sauce mixture of about two tablespoons soy sauce, two tablespoons mirin, and four tablespoons water. If you do not use mirin, a small pinch of sugar mixed into the water can soften the saltiness, though the flavor will be different. Thinly sliced scallion or grated ginger makes an optional finish.
Just before cooking, pat the tofu again. You can leave it plain or dust the broad sides lightly with cornstarch for a more defined crust. Shake off any excess: a thin coating browns more evenly and is less likely to leave loose starch in the pan.
Brown first, then build the sauce
Warm a thin layer of oil in a skillet over medium heat. Lay the tofu in the pan and leave it undisturbed until the underside looks golden and releases readily. Turn each piece with a wide spatula, supporting it as you lift, and brown the second side. If the pan seems too hot or the coating darkens quickly, lower the heat. Move the browned tofu to a plate.
Add the mushrooms to the same pan. Cook, stirring occasionally, until they soften and some of their released moisture evaporates. If the pan looks dry, add a small splash of oil. Stir the soy sauce, mirin, and water together before pouring them in, then let the mixture simmer briefly. Taste a little sauce and add water if it is stronger or saltier than you want; it will taste more balanced alongside plain tofu and rice.
Return the tofu to the pan for a short simmer, spooning sauce over the top. Keep the heat moderate and avoid repeated turning, which can break the pieces. For a thicker sauce, mix a small amount of cornstarch with cold water and stir it into the bubbling liquid a little at a time. Stop when the sauce lightly coats a spoon rather than becoming a heavy glaze.
Serve it as part of an everyday meal
Serve the tofu promptly, with mushrooms and sauce spooned over each piece. A bowl of rice catches the extra sauce, while simply cooked greens or sliced cucumber provide a fresh contrast. Scallion adds a mild bite; ginger brings a sharper note. Neither is essential, so the dish can suit what you already have.
Once the basic method feels familiar, vary one element at a time. Try a mixture of mushrooms for different textures, or replace some of the water with unsalted dashi for a different savory base. Keep the sauce relatively light so it complements the tofu rather than hiding it. If you are cooking ahead, store the tofu and sauce together in the refrigerator and reheat gently; the crust will soften, but the dish will still be good with freshly cooked rice.
