How To Make Air Fryer Sweet and Sour Cauliflower

Medium cauliflower head trimmed and cut into bite-sized florets, patted dry for crispiness.

Step 1: Trim a medium head of cauliflower and cut it into bite-sized florets. Pat dry with a paper towel to remove excess moisture for a crispier finish

Mixing bowl with flour, cornstarch, milk, and seasonings whisked into smooth batter.

Step 2: In a mixing bowl, combine 1/2 cup flour, 2 tablespoons cornstarch, 1/2 cup milk, 1 teaspoon garlic powder, 1 teaspoon onion powder, 1 teaspoon salt, and 1/2 teaspoon black pepper. Whisk until smooth.

Step 3: Dip each cauliflower floret into the batter, making sure it’s fully coated. Shake off excess batter.

Step 4: Preheat your air fryer temperature to 400 degrees F (200°C). Place the coated florets in a single layer in the basket, avoiding overcrowding. Lightly spray with cooking spray. Set cook time for 10-12 minutes, shaking the basket halfway through, until golden and crisp.

Step 5: Transfer the hot cauliflower to a large bowl. Pour 1/2 cup of sweet and sour sauce over the cauliflower and toss gently to coat. Serve immediately as a side dish, appetizer, or over rice for a full meal.

Easy Air Fryer Sweet and Sour Cauliflower Recipe Tips

  • Dry the florets well: Patting your cauliflower dry removes extra moisture, which helps the batter stick and ensures a crispier finish.
  • Don’t overcrowd the basket: Air circulation is key for even crisping, so cook in batches if needed.
  • Use a light spray of oil: A quick mist of cooking spray gives the cauliflower a golden, crunchy exterior without adding extra grease.
  • Adjust sauce to taste: Start with half the sauce and toss more gradually—you don’t want soggy cauliflower.
  • Serve immediately: This dish is best enjoyed hot for maximum crispiness; if reheating, a quick air fry restores crunch.

Storing, Freezing and Reheating Instructions

  • Storing: Place cooled cauliflower in an airtight container and store in the refrigerator for up to 3 days. Keep the sauce separate if possible to prevent the florets from getting soggy.
  • Freezing: Flash-freeze the cooked cauliflower on a baking sheet for 1–2 hours, then transfer to a freezer-safe bag or container. Store for up to 2 months and thaw in the refrigerator before reheating.
  • Reheating: Reheat in the air fryer at 375°F (190°C) for 5–7 minutes to restore crispiness. Avoid microwaving, as it can make the cauliflower soft and soggy.
