Steps

Before you start

Pat calamari completely dry with paper towels (moisture prevents crispness)
Preheat air fryer to 400°F (200°C) for 3 minutes
Zest lemon before juicing if you'll need the juice for serving
Have a bowl of ice water ready to soak calamari tubes for a few minutes before slicing (makes them firmer and easier to cut)

1
Mix dry coating
- In a small bowl, whisk together all-purpose flour (½ cup / 60 g), cornstarch (3 tbsp / 27 g), lemon zest (1 tbsp / 6 g), freshly cracked black pepper (¾ tsp / 1.5 g), garlic powder (¼ tsp / 0.5 g), and fine sea salt (½ tsp / 3 g).
- Set aside.

Ready when: Ingredients fully combined with no lumps
Tip: Whisking the dry ingredients first ensures even distribution of lemon zest and pepper throughout the coating
2
Create batter
- Pour active sourdough discard (¾ cup / 180 ml) into a medium shallow bowl.
- Add the dry mixture to the discard and stir with a fork until a thick, smooth batter forms.
- The batter should coat the back of a spoon and be slightly thicker than pancake batter.

Ready when: Batter is thick and uniform with no dry flour streaks
Tip: Do not overmix—lumps are fine and may even produce a slightly crispier coating
3
Coat calamari
- Working in batches, drop calamari rings into the batter, stirring gently with a fork to coat all sides.
- Use tongs or a small skewer to lift each ring, let excess batter drip back into the bowl for 2–3 seconds, and place on a plate.
- Repeat until all calamari is coated (approximately 28–32 rings and tentacle pieces).

Ready when: Each piece is evenly coated with a thin layer of batter
Tip: Do not let coated pieces sit longer than 1 minute before air frying, or they may absorb moisture and lose crispness
4
Spray and arrange
- Lightly mist the air fryer basket with olive oil spray.
- Arrange coated calamari in a single layer in the basket, spacing pieces about ½ inch apart (they should not touch or overlap).
- Work in batches if needed.
- Spray the top of the calamari lightly with olive oil spray (about 1.5 tbsp / 22 ml per batch).

Ready when: Basket is coated and calamari is arranged in a single, not-touching layer
Tip: The oil spray is critical for crispness; don't skip it or use too little, as the sourdough batter needs fat to brown
5
Air fry first batchOven 400°F / 205°C
- Place the basket in a preheated 400°F (200°C) air fryer.
- Fry for 10–12 minutes, shaking the basket gently at the 6-minute mark to ensure even browning.
- The calamari is done when the coating is deep golden-brown and crispy, and the rings are tender inside (a quick bite should reveal soft calamari with no translucence).
+ Show details− Hide details
Ready when: Coating is deep golden-brown; calamari is opaque white and tender when tested with a fork
Tip: If your air fryer runs hot, check at 8 minutes; some models brown faster than others. Calamari cooks very quickly, so don't overcook or it will become rubbery
6
Rest and serve
- Transfer the first batch to a paper towel-lined plate to rest for 1–2 minutes (this sets the crispy coating).
- Repeat steps 4 and 5 with the remaining calamari if cooking in batches.
- Serve immediately while hot and crispy, with lemon wedges, marinara sauce, or garlic aioli.

Ready when: Paper towels absorb excess surface oil; pieces remain crispy
Tip: Serve within minutes of cooking for maximum crispness; reheating in the air fryer for 2 minutes at 350°F will restore some crispness if needed

Good to know

Tips

Sourdough discard should be bubbly and active (fed 4–8 hours before use) for best lift and crispness in the coating. Inactive discard will result in a heavier, denser coating.
Patting calamari completely dry is non-negotiable—even small amounts of moisture will steam the coating instead of crisping it. Use multiple paper towels if needed.
Don't crowd the air fryer basket; calamari needs air circulation. If you have a large batch, cook in two rounds rather than overpacking.
The sourdough batter has a subtle tang that pairs beautifully with acidic dipping sauces; try a quick marinara with extra lemon juice, or a garlicky mayo mixed with lemon zest for maximum flavor harmony.

Make ahead

You can prepare the dry coating mix up to 3 days ahead and store it in an airtight container at room temperature. Clean and prep calamari up to 4 hours ahead, store covered in the refrigerator, and pat dry just before coating. The batter should be made fresh no more than 30 minutes before frying.

Storage & reheating

Store cooled leftovers in an airtight container in the refrigerator for up to 1 day. To reheat: place on the air fryer basket and heat at 350°F (175°C) for 2–3 minutes to restore crispness. Do not microwave, as this will make the coating soggy. Freezing is not recommended due to the texture degradation of both calamari and the sourdough coating.

Substitutions

fresh calamari tubes and tentacles → cleaned shrimp (peeled and deveined, tail-on or off) or white fish cut into bite-sized pieces. Use similar weight; shrimp will cook in 8–10 minutes, fish in 9–11 minutes at the same temperature
active sourdough discard (fed 4–8 hours prior, bubbly) → ¾ cup (180 ml) active sourdough starter or ¾ cup (90 g) all-purpose flour mixed with ¼ cup (60 ml) milk and 1 tbsp (15 ml) sour cream. The substitution will lack the tangy depth; the sourdough discard is integral to the flavor profile
lemon zest → 1 tbsp (6 g) finely grated Parmesan cheese or ½ tsp (1 g) dried oregano plus ¼ tsp (0.5 g) paprika. Parmesan adds umami and crispness; herbs shift the flavor toward Italian rather than Mediterranean-bright
cornstarch → 3 tbsp (30 g) potato starch or tapioca starch. Both will yield similarly crispy results, though tapioca may brown slightly faster; watch closely
