Sweet And Sour Air Fryer Cauliflower Ingredients
For the Cauliflower
Cauliflower The star ingredient that provides the perfect crunch; make sure it s firm for the best texture.
Olive Oil Enhances the flavor and helps achieve that crispy finish, or swap it with avocado oil for a high smoke point.
Cornflour (Cornstarch) Essential for that coveted crispy coating; if you re out, potato starch can work just as well.
For the Sauce
Onion Adds a touch of sweetness; for a milder flavor, try using red onion.
Red Capsicum (Bell Pepper) Brings color and a nice crunch; you can use yellow or orange varieties for a twist.
Pineapple (Canned, with juice) Imparts natural sweetness and acidity; fresh pineapple is a fine substitute but may need added sugar.
Tomato Sauce Acts as the base for the sweet and sour sauce; ketchup can be a quick alternative if needed.
Soy Sauce Provides that umami richness; low-sodium soy sauce is a healthier choice.
White Vinegar Adds tanginess to the mix; if you prefer a fruity note, apple cider vinegar can be used instead.
Water Helps to adjust the sauce consistency, ensuring it s just right for coating.
This Sweet And Sour Air Fryer Cauliflower is not just a dish; it s an experience waiting to happen!
How to Make Sweet And Sour Air Fryer Cauliflower
Prep Cauliflower: Begin by steaming, boiling, or microwaving the cauliflower for about 5 minutes until it s just firm. Drain well to prevent excess moisture in the dish.
Coat Cauliflower: In a large bowl, toss the cauliflower pieces with olive oil and cornflour until each piece is evenly coated. This will ensure that they have that perfect crispy texture when cooked.
Air Fry: Preheat your air fryer to 200 °C (392 °F). Place the coated cauliflower in the fryer basket and cook for 10 minutes. Remember to shake the basket halfway through to ensure even crispiness.
Cook Sauce: While the cauliflower is air frying, heat a small amount of oil in a pan over medium-high heat. Sauté the onion and red capsicum for 2-3 minutes until they soften and begin to caramelize.
Simmer Sauce: Next, add the pineapple, tomato sauce, soy sauce, white vinegar, and water to the pan. Let it simmer uncovered for about 10 minutes, stirring occasionally until the sauce thickens and becomes glossy.
Combine: Once the cauliflower is done, carefully toss it in the sweet and sour sauce, ensuring each piece is well-coated. Serve immediately for the best texture and flavor.
Garnish: Just before serving, top with a sprinkling of sesame seeds and sliced green onions for an extra pop of flavor and color.
Optional: Add some crushed red pepper flakes for a spicy kick!
