Sweet and Sour Tofu Veggie Stir Fry is as simple and easy as it gets! The tofu is baked to crisp perfection with a perfect meaty texture and the sweet and sour Asian stir-fry sauce is so delicious! A quick vegan dinner that comes together in a cinch whenever that craving for takeout hits.

Be prepared to convert tofu haters into lovers with this sweet and sour tofu stir fry! Crispy tofu coated in a sweet and sticky sauce along with crisp colorful veggies!
Oh yes, I love me a good tofu dish! Have you tried my Tofu Katsu Curry? A reader favorite! Tofu can be so delicious when prepared right. And in this quick sweet and sour stir-fry we really give it the treatment it deserves!
As with many tofu recipes, the trick for this dish is to rid the tofu of excess moisture. Because no one likes soggy tofu! Then we fry it up real nice or bake it in the oven.

Once fried or baked crispy, we toss the tofu cubes in a super irresistible sweet and sour sauce and some sauteed veggies. DONE! Serve it up on a fresh bed of rice like I did, on quinoa or mashed potatoes, or on top of some cooked veggies or cauliflower rice!

Delicious! Such a great recipe. I caramelized some fresh pineapple pieces to add, because I had some to use up, and with the tofu I froze and defrosted it before pressing for extra crispiness. So good.
Very good. Next time I might make it a tad less spicy and also cut the veggies smaller
Awesome
