A simple version of sweet and sour tofu brings authentic Asian flavors to your kitchen using five essential ingredients. This vegetarian dish transforms plain tofu into crispy, sauce-coated bites that satisfy sweet and tangy cravings.
The key to success is appropriately preparing the tofu before cooking and creating the perfect sauce consistency. This dish delivers a satisfying combination of textures – a crispy exterior, a tender interior, and a glossy sauce that clings to each piece.
Ingredients:
- 1 block firm tofu (14 oz)
- 1/2 cup ketchup
- 1/4 cup brown sugar
- 2 tablespoons soy sauce
- Vegetable oil for frying
Press tofu between paper towels and heavy plates for 30 minutes to remove excess moisture. Cut into 1-inch cubes and pat dry again—heat oil in a large pan over medium-high heat. Fry tofu cubes until golden brown on all sides, about 3-4 minutes per side. Meanwhile, mix ketchup, brown sugar, and soy sauce in a bowl. Once the tofu is crispy, reduce heat to low, pour the sauce mixture over the tofu, and stir gently until the sauce thickens and coats all pieces evenly.
For best results, ensure tofu is thoroughly pressed and dried before frying – this is crucial for achieving crispiness. The sauce will thicken naturally as it heats, but add a tablespoon of water if it becomes too thick. Store leftovers in an airtight container in the refrigerator for up to three days, though the tofu will lose its crispiness over time.
History of Sweet and Sour Tofu
While the exact origins of sweet and sour tofu are unclear, the dish emerged as a vegetarian adaptation of traditional Chinese sweet and sour dishes that typically featured meat or fish. The transformation began during China’s Tang Dynasty (618-907 CE), when Buddhist vegetarianism gained prominence and creative chefs sought meat alternatives.
Sweet and sour flavoring dates back over 2,000 years in Chinese cuisine, appearing in ancient texts describing the perfect balance of five tastes. The combination of sugar and vinegar created that signature tangy sauce that would later define this beloved dish.
During the 20th century, as vegetarianism spread globally and tofu gained international recognition, sweet and sour tofu became a popular menu item in Chinese restaurants worldwide. The dish exemplifies how traditional recipes can evolve to embrace changing dietary preferences while maintaining cultural authenticity.

For best results, verify that the tofu is well-pressed and thoroughly dried before coating it with cornstarch. The oil temperature is essential for achieving crispy tofu – too hot will burn the outside while leaving the inside soggy, and too cool will make the tofu greasy. The sauce can be prepared and stored in the refrigerator for up to 3 days. The leftover dish can be stored in an airtight container for up to 2 days, though the tofu will lose its crispiness upon reheating.
Cooking Steps
The cooking process for sweet and sour tofu begins by pressing it until it releases excess moisture, then cutting it into uniform cubes for even cooking.
Once prepared, each cube gets a light coating of cornstarch, which creates a crispy exterior when fried to a golden brown in hot oil.
The final step combines everything as the homemade sweet and sour sauce is poured over the crispy tofu, transforming this humble protein into a restaurant-worthy dish.
Step 1. Press Tofu Until Dry
Pressing excess moisture from tofu is a critical first step that creates the ideal texture for sweet and sour dishes. The drier the tofu, the better it will absorb flavors and achieve that perfect crispy exterior when cooked.
Start by wrapping your block of firm tofu in paper towels or a clean kitchen cloth. Place it between two flat surfaces – a cutting board works well for the bottom, while a baking sheet makes an ideal top layer.
Add weight gradually using heavy cans or cookbooks. Let the tofu press for at least 30 minutes, though an hour gives the best results. You’ll be amazed at how much liquid emerges!
Change the wrapping halfway through if it becomes overly saturated. When done, your tofu should feel noticeably firmer and ready for the next step.
Step 2. Cut Tofu Into Cubes
Carefully slice the pressed tofu block into uniform 1-inch cubes, guaranteeing each piece has clean edges and similar dimensions. A sharp knife and a steady hand are essential for perfect little squares that will become deliciously crispy when cooked.
Place your tofu block on a clean cutting board and cut it lengthwise into three even slabs. Turn these slabs horizontally and slice them into three strips. Finally, cut across these strips to create your cubes. Think of it like making a tiny tofu city of perfectly aligned blocks!
Keep your knife blade clean between cuts by wiping it with a damp cloth for best results. This prevents the tofu from sticking and guarantees each cube has that professional, restaurant-quality appearance your dish deserves.
Step 3. Coat Tofu With Cornstarch
Now that your tofu cubes are perfectly shaped preparing them for a crispy exterior begins with a proper cornstarch coating.
Place about 1/2 cup of cornstarch in a large bowl or zip-top bag, ensuring you have enough to evenly coat all your tofu pieces.
Working in small batches, gently toss the tofu cubes in the cornstarch.
Ensure each piece gets a thin, even coating – think of it as giving your tofu a light winter jacket rather than a heavy parka.
Shake off excess cornstarch by gently tapping the pieces against the bowl’s side.
For extra insurance against sogginess, let the coated pieces rest on a wire rack for 5 minutes before cooking.
This helps the cornstarch adhere better and creates that irresistibly crispy exterior we all hope for.
Step 4. Fry Tofu Until Golden
Add enough vegetable oil to create a 1/4-inch layer on the bottom when your wok or large skillet reaches medium-high heat.
Once the oil begins to shimmer and a small piece of tofu sizzles when added, you’re ready to start frying.
Carefully place the cornstarch-coated tofu pieces into the hot oil, making sure not to crowd the pan.
Work in batches if necessary – overcrowding will lower the oil temperature and result in soggy tofu. Trust me, I learned this lesson the hard way!
Let each piece fry for 2-3 minutes until golden brown on the bottom, then gently flip using tongs or a spatula.
Continue frying until all sides are crispy and evenly golden.
Remove the tofu with a slotted spoon and place it on paper towels to drain the excess oil.
Step 4. Pour Sweet-Sour Sauce
The golden-brown tofu pieces are ready for their flavorful coating. Pour the prepared sweet and sour sauce slowly over the tofu while it’s still in the hot pan, ensuring each piece gets evenly coated. The sauce will begin to bubble and thicken almost immediately.
Gently toss the tofu pieces using a wooden spoon or silicone spatula, being careful not to break them. The sauce should cling to each piece, creating an absolutely irresistible glossy sheen.
Let it simmer for about 2-3 minutes until the sauce reaches your desired consistency. If the sauce becomes too thick, add a splash of water or pineapple juice to thin it out.
Watch as the tofu transforms from simply crispy to gloriously glazed – it’s like giving your tofu a sweet and tangy winter coat!
