  • 420 grams firm tofu sliced into cubes
  • 1 red bell pepper diced
  • 1 onion diced
  • 1 cup pineapple diced or canned pineapple works too
  • cup Cornstarch to coat tofu (you may substitute with potato or tapioca starch)
  • ½ tsp salt
  • 2 tbsp vegetable oil to coat tofu
  • 1 tsp vegetable oil for cooking

Sweet and sour sauce:

  • 1 tbsp Soy sauce
  • ¼ cup Rice vinegar
  • 3 tbsp Ketchup
  • 3 tbsp Sugar
  • 1 tbsp Cornstarch
  • cup Water
  • Optional: green onion finely sliced for garnish


  • In a small bowl, whisk together your ingredients for the sweet and sour sauce.
  • Strain your tofu of the liquid and slice into bite size cubes. Pat dry with paper towel. On a clean dry plate, add cornstarch and generously coat each tofu cube. Add more cornstarch if needed.
  • Transfer coated tofu into your air fryer giving each piece enough room (you may need to do this in two batches depending on the size of your air fryer). If you don’t have an air fryer: please refer to Notes section for instructions on how to fry.
  • If you’re able to fit all the tofu in one batch, spray or drizzle 1 tbsp of vegetable oil over the tofu and then season with ¼ tsp of salt. If you must divide the tofu into two batches, use ½ tbsp oil and ⅛ tsp salt. Air fry at 400 degrees for 10 minutes on one side.
  • Flip the tofu over, add oil and season with salt. Air fry at the same temperature for 5 minutes. The tofu should come out crispy, if it’s not crispy enough air fry for 1-2 more minutes.
  • Meanwhile in a hot wok set over medium heat, add 1 tsp vegetable oil. Add onions and bell pepper and mix. Cook until onions are translucent. Then add pineapple and mix again. Pour your sweet and sour sauce into the hot pan and stir. Raise the heat to high and allow the sauce to simmer and thicken. Once thickened, lower the heat to VERY LOW until your tofu has completely fried.
  • Once the tofu has air fried, pour the crispy tofu into the sauce and veggies. Gently mix until the tofu is covered in sauce. Serve onto a plate and enjoy! Optional: Garnish with green onions.

How to fry tofu without air fryer?
In a hot pan set over medium heat, add ⅓ cup vegetable oil. Once oil is hot, gently lower your coated tofu into the pan. Fry on each side until golden crispy brown, about 4-5 minutes per side depending on heat level. As it’s frying, sprinkle enough salt to cover your tofu. Once fried then toss the crispy tofu into sauce and veggies to gently mix.
