Air Fryer Sweet and Sour Tofu

Air Fryer Sweet and Sour Tofu. Crispy tofu smothered in a sweet tangy sauce accompanied with crunchy bell peppers, onions, and juicy pineapple. This vegan sweet & sour tofu recipe is simple to make at home and tastes just like Chinese takeaway but with tofu instead. It’s fantastic for dinner or lunch and great as leftovers.

If you don’t have an air fryer, DON’T WORRY! I got you covered, I’ve shared instructions on how to fry the tofu so it’s crispy and delicious.

My husband is back to eating more vegetarian foods which means that I am getting more creative in the kitchen again. I asked him, “What’s an exciting way to cook tofu?” and he said, “Sweet and Sour!” The next morning, I got to working on this air fryer tofu recipe. It was so good he had seconds and I think thirds too! He said 5/5 stars and I was okay this is going into the books! And now my crispy sweet and sour tofu dish is here for you to make at home.

Healthier!

These sweet and sour tofu balls are amazing! If you know what Chinese restaurant style Sweet and Sour Chicken tastes like, then this recipe is just like that! But it’s better because it’s healthier since it’s made in the air fryer and if you’re frying, the recipe only calls for ⅓ cup of oil (not 2 cups+ of oil to deep fry like at most restaurants).

Easy to make!

My sweet and sour tofu recipe is simple to make at home! You’re simply cutting your tofu and veggies into bite size pieces. (Ps. I also share a video tutorial below so check it out!). Then in a small bowl whisk together you sauce ingredients.

Next coat your tofu in cornstarch and place them into your air fryer with some space around each cube. Spray oil over top and season with salt. You may need to do this in two batches if you have a smaller air fryer. (If you don’t have an air fryer, simple set a pan over medium heat with ⅓ cup vegetable oil and fry them on each side until golden crispy brown). Air fry on one side for 10 minutes and then flip the tofu over and fry on the other same for 5 minutes.

Meanwhile as the tofu is frying or air frying, in a wok set over medium high heat add more vegetable oil followed by onions, bell pepper and fry until onions are slightly translucent but still firm. Then add pineapples into the mix. Stir in your sauce and raise the heat until the sauce bubbles and becomes thick. Once it’s thick toss in your fried tofu and gently mix. Once mixed, remove off the heat and serve!

FAQ

Below are frequently asked questions about this sweet and sour tofu recipe:

Is sweet and sour tofu vegan?

My sweet and sour tofu Chinese style recipe is! It all depends on if you add egg to coat the tofu prior to frying. My recipe is completely vegan and eggless.

What is sweet and sour tofu?

Its crispy fried tofu smothered in a sweet tangy ketchup sauce with bell peppers, onion, and pineapple.

Do I need to use cornstarch?

Yes, you need some starch to coat the tofu prior to frying or it won’t be as crispy, and the sauce requires it to thicken. If you’re allergic to cornstarch, please substitute with potato or tapioca starch for the tofu and the sauce.

Can I skip the pineapples?

Yes, but just be warned that it won’t taste as authentic as the Chinese takeaway as they use pineapples.

Can I use medium or soft tofu?

No, I wouldn’t recommend it, or I’ll be challenging to flip in the air fryer or in the pan. Please use firm or extra firm tofu.

Can I add other veggies to this sweet and sour fried tofu recipe?

Yes! I would suggest broccoli, snap peas, green beans, cauliflower, or carrots. Any hard veggies.
