Sweet and sour tofu, made in just 30 minutes. A plant-based version of this classic Chinese food that is much healthier than take-out!

Tofu is a staple in my kitchen. I use it a lot and, lately, I've been obsessed with this delicious sweet and sour tofu. It’s a great meat alternative, especially when you’re trying to recreate meat-based dishes because, if you cook it properly, you can get a similar texture.
This sweet and sour tofu recipe is super flavorful and ready in just 30 minutes. Besides, it is way better and healthier than take-out. It makes the perfect dinner!
How to make sweet and sour tofu
- Mix the soy sauce and apple cider vinegar in a bowl until well combined.
- Incorporate the tofu cubes and let marinate for at least 5 minutes.
- Drain the tofu and transfer โ of the tofu cubes to a freezer bag with 2 tablespoon of cornstarch and toss to coat. Repeat this step with all the remaining tofu and cornstarch.
- Heat half of the oil in a skillet and when it’s hot, incorporate the tofu cubes. Cook over medium-high heat until all sides are golden brown. Remove the tofu from the skillet and set aside.
- Heat the other half of the oil in the skillet and add the veggies. Cook over medium-high heat until golden brown. Set aside.
- To make the sauce just mix all the ingredients until well combined.
- Pour the sauce into the skillet or pan and cook until it thickens.
- Mix the tofu, veggies, and sauce in the skillet, stir, and cook for about 5 minutes over medium heat.
- Serve your sweet and sour tofu immediately.
Sweet and sour tofu ingredients and tips
- Soy sauce or tamari: I used soy sauce, but tamari is a good gluten-free alternative. If you don't consume soy, coconut aminos is a great substitute. You could also add the same amount of water or vegetable stock and add more salt.
- Apple cider vinegar: you could also use white vinegar or lemon juice instead.
- Firm tofu: firm or extra firm tofu work best for this sweet and sour tofu recipe. Soft or silken tofu is not a good choice as it will fall apart easily.
- Cornstarch: I’ve only made this recipe using cornstarch, but any type of starch should work.
- Extra virgin olive oil: I’m Spanish, so I use extra virgin olive oil to cook most of my dishes. However, any type of oil will work. I always use extra virgin oils when possible because they’re healthier.
- Carrot.
- Green bell pepper.
- Red bell pepper.
- Onion.
- Sugar: I used brown sugar, but feel free to use the type of sugar you want, or even other sweeteners like maple or agave syrup.
- Tomato paste: it can be replaced by tomato puree, ketchup, or tomato sauce.
- Water.

- Heat the other half of the oil in the skillet and when it’s hot, incorporate the veggies (carrot, green bell pepper, red bell pepper, and onion). Cook over medium-high heat until golden brown. Set aside.

Notes
- Some people add pineapple to this sweet and sour tofu recipe, but I don’t. If you want to enjoy this dish with pineapple, just sautée it with the veggies.
- Feel free to use any type of vinegar, starch, oil, veggies, or sweetener you have on hand.
- Tomato paste can be replaced by tomato puree, ketchup, or tomato sauce.
- The amount of sodium is not a real measurement because you’d need to marinate the tofu for hours for it to absorb all the soy sauce.

Jay says
Not sure where I went wrong, but this recipe did not work out for me at all! The tofu tasted entirely like cornstarch and my sauce was severely lacking in flavor. The only change I made was ketchup instead of tomato paste. Oh well :/

Thank you for this tofu recipe! This was so delicious and I really liked the texture of the tofu. My carnivore boyfriend thought this was better than sweet and sour chicken at our local Chinese restaurant. ๐
Iosune Robles says
Hi Meri! So glad you and your boyfriend liked our tofu recipe ๐ Have a nice day!
Jenny says
Very easy and tasty! Added some broccoli. Ran out of cornstarch and used tapioca starch instead. The coating still stuck but got a bit gooey when everything was combined. Maybe cause of my substitution? Iโd make this again though!
Iosune Robles says
Hi Jenny! Probably cause tapioca tends to be thicker than cornstarch. Next time if you need to use tapioca again you can try with less. Thank you for writing!! Have a great day!
