The Secret to Ultra Crispy Sweet and Sour Chicken

The key to getting that signature Crispy Sweet and Sour Chicken texture is all in the coating. Here’s what makes this recipe shine:

1. Buttermilk for Maximum Tenderness 🥛

Soaking the chicken in buttermilk not only adds flavour but also keeps the meat extra juicy. The slight acidity tenderises the chicken, ensuring every bite is melt-in-your-mouth perfect.

2. A Gluten-Free, Spiced Flour Mix for Extra Crunch 🌾

Instead of traditional plain flour, I use gluten-free flour mixed with cornstarch (cornflour in Australia!) and a touch of garlic powder, onion powder, and paprika. The result? A light, crisp coating that puffs up beautifully in the air fryer.

3. Air Fryer Magic – Crispy Without the Grease! ✨

Deep-frying might be delicious, but it’s messy and heavy. Cooking the chicken in the air fryer gives you that golden crunch with just a light spray of oil. Healthier, easier, and just as crispy!

The Ultimate Sweet & Sour Sauce 🍍🍯

Now, let’s talk about that sauce – because Crispy Sweet and Sour Chicken is nothing without the perfect balance of flavours!

The Key Ingredients for an Authentic Taste:

  • Pineapple Juice & Chunks 🍍 – Natural sweetness that brings out the tangy elements of the sauce.
  • Rice Vinegar 🍶 – Essential for that signature sour kick.
  • Tomato Sauce & Tomato Paste 🍅 – For colour and depth.
  • Brown Sugar & Honey 🍯 – Sweet, caramelised goodness to balance the vinegar.
  • Soy Sauce 🥢 – Adds a savoury umami depth.
  • Cornflour Slurry – To thicken the sauce to that glossy, sticky consistency.

Made in minutes in the Sunbeam Electric Skillet, this sauce coats every crispy bite with pure deliciousness!

Tips for the Best Crispy Sweet and Sour Chicken 💡

  • Don’t skip the buttermilk soak – It makes the chicken ridiculously juicy.
  • Use cornstarch (cornflour) in the coating – This is the secret to extra crispiness!
  • Shake off excess flour before air frying – This prevents a floury aftertaste.
  • Preheat the air fryer – Helps the coating crisp up immediately.
  • Toss the chicken in the sauce just before serving – This keeps it crunchy!
Serving & Pairing Suggestions 🍽️

This Crispy Sweet and Sour Chicken dish is a showstopper on its own, but if you want to take it to the next level, serve it with:

  • Steamed Jasmine Rice – The perfect fluffy base to soak up that sauce.
  • Garlic Bok Choy or Stir-Fried Veggies – A fresh, crunchy contrast.
  • Fried Rice – Because why not go all out?
  • Chilli Flakes or Fresh Sliced Chilli – If you love a spicy kick!

And don’t forget the extra sweet and sour sauce on the side for dipping!

How to Store & Reheat Leftovers 🍱

If you manage to have any Crispy Sweet and Sour Chicken leftovers (unlikely, but just in case! 😉), here’s how to store and reheat them:

Fridge:

Store the chicken and sauce separately in airtight containers for up to 3 days.

Freezer:

Freeze the cooked chicken on a baking tray before transferring to a ziplock bag. It stays fresh for up to 2 months! The sauce can be frozen in a separate container.

Reheating:

For best results, pop the chicken back in the air fryer at 180°C for 5–7 minutes to crisp it up again. Heat the sauce separately on the stovetop or microwave.
