sweet and sour tofu with broccoli, pineapple,and rice in a white bowl.

About the Recipe

Though this is not an authentic Chinese recipe, I think you'll agree it has its perks. The sweet and sour flavors come from a few key ingredients you probably already have on hand, like soy sauce, rice vinegar, and maple syrup.

In fact, this dish is surprisingly pantry-friendly. You can even substitute frozen vegetables for the fresh produce!

I love how versatile sweet and sour tofu is. Almost any vegetable you have in the fridge that needs to be put to use will be right at home in this flavorful sauce - think broccoli, cauliflower, spinach, or snow peas. See the Variations section below for ideas.

And the tofu crisps up nicely with a bit of oil and soy sauce. It's firm, chewy, savory, and oh so satisfying.

Ingredient Notes

tofu - I like super firm tofu for this dish since it doesn't need to be pressed. Extra-firm is also great, but you'll want to press it for about 30 minutes before cooking.
Time-saving tip! Use baked tofu, which doesn't need to be pressed AND is already seasoned. This means you can skip Step 1 in the recipe instructions.
onion & bell pepper - I used a sweet onion and green and red bell peppers; feel free to use other varieties.
pineapple - canned pineapple adds wonderful sweetness and flavor to the dish and helps keep it pantry-friendly.
soy sauce - or use certified gluten-free tamari
maple syrup - this combines with the pineapple juice to create a sticky, thick glossy sweet sauce!
rice vinegar - critical to the overall flavor of the dish, rice vinegar adds acidity to the sweet & sour sauce.
corn starch - a small amount of added starch helps thicken the sauce; feel free to substitute arrowroot, if needed.

How to Make Sweet and Sour Tofu

Sweet and sour tofu is a classic dish everyone knows and loves, but you might not realize how EASY it is to make at home.

The basic process looks like this:

Press and cube the tofu (no need to press if using super firm tofu), and chop the vegetables.

Season and cook the tofu in a large pan until golden brown, then transfer it to a plate.

In the same pan, sauté the onion, peppers, and canned pineapple. Return the crispy tofu to the pan.

Whisk together the vegan sweet and sour sauce in a small bowl, and pour into the pan. Cook until thickened, and serve.

Serving Suggestions

Serve sweet and sour tofu with your favorite rice. It's also delicious over quinoa or noodles.

Garnish with fresh green onion and sesame seeds, if desired.

Variations

I had a small amount of broccoli that needed to be used, so I tossed that near the end of cooking. Sweet and sour tofu is one of those great dishes that can take on pretty much any vegetable you have on hand.

Other vegetables you can include in sweet and sour tofu:

green beans
snow peas
baby corn
kale
spinach
Swiss chard
carrot
mushrooms
cauliflower
spicy peppers

Oil-free - If you follow an oil-free diet, sweet and sour tofu can easily be made without oil. Simply sauté the tofu and veggies in your favorite non-stick pan, and use a bit of broth or water as needed to prevent sticking.

Refined sugar-free - opt for tomato paste over ketchup, or use my favorite healthy barbecue sauce.

Other proteins - if you don't have tofu on hand or just feel like switching things up, this dish is also great with chickpeas, tempeh, Butler soy curls, or seitan!

Storing

Store leftovers in an airtight container in the refrigerator for up to 5 days. Reheat in the microwave or on the stovetop.

Tip: since sweet and sour tofu reheats so well, it's a great recipe to add to your weekly meal prep rotation.

Equipment

large saute pan

Ingredients

2 teaspoons vegetable oil, divided - See Notes section for oil-free tips.
3 Tablespoons low-sodium tamari or soy sauce, divided
3 Tablespoons rice vinegar or white wine vinegar, divided
1 (14 ounce) package extra firm tofu, drained, pressed, and cubed - or super-firm tofu (no need to press)
1 small sweet onion, chopped
1 red bell pepper, seeded and chopped
1 green bell pepper, seeded and chopped
1 cup canned diced pineapple, juice reserved
1 Tablespoon tomato paste or ketchup - I had an open bottle of BBQ sauce in the fridge so I used that instead.
2 Tablespoons maple syrup
1 Tablespoon corn starch
4 cups cooked rice of choice

Instructions

Heat 1 teaspoon of oil in a large pan over medium-high heat, along with 1 tablespoon tamari and 1 tablespoon vinegar. Add the tofu to the pan and cook, stirring occasionally, until golden brown on all sides, about 10 minutes. Transfer the tofu to a plate.
Add the remaining 1 teaspoon of oil to the pan along with the onion. Cook, stirring frequently, until it begins to brown, about 5 minutes. Add the bell peppers and the pineapple to the pan. Cook, stirring occasionally, until the vegetables have softened, about 10 more minutes. Add the tofu back into the pan.
Whisk together the tomato paste, maple syrup, cornstarch, remaining 2 tablespoons tamari, 2 tablespoons vinegar, and ½ cup of the reserved pineapple juice in a small bowl. Pour the mixture into the pan and gently stir to coat everything well. Cook for a few more minutes, until the sauce thickens and is heated through.
Serve over the cooked rice.

Notes

First-Timer tip: If you’re short on time, you can used store-bought baked tofu and a bag of frozen stir-fry vegetables in this recipe. Baked tofu is already seasoned, so you can skip step 1. Just add it to the pan with the frozen veggies in step 2 and add the sauce after they’re both heated through.

Need to make it oil-free? Instead of cooking the tofu in oil in the first step, dry-broil it as described in this post. Another option is to season the tofu with tamari and rice vinegar, then bake. Or simply sauté it as described above and add a bit of broth or water, as needed. Thoroughly pre-heating the pan is also very important to prevent sticking.

Storage: Store leftover sweet and sour tofu in an airtight container in the refrigerator for up to 5 days. Reheat in the microwave or on the stovetop.
