Cooking Tips
- Cut Fries Evenly: Cut the sweet potatoes into similarly sized thin fries so they cook at the same rate. Avoid overcrowding the baking sheet, which can cause them to steam rather than brown.
- Crush Oats Finely: Process or crush the oats until they resemble coarse crumbs. This helps the coating adhere to the fish and creates a more even crispy exterior.
- Dry Fish Well: Pat the cod or haddock thoroughly dry before dipping it in egg. Removing excess surface moisture helps the almond-oat coating stick and crisp in the air fryer.
- Boost The Fibre: Serve each plate with the optional cabbage slaw or another non-starchy vegetable. Choose a slaw without a sugar-heavy dressing to keep added sugars low.
- Cook In Batches: Leave space around each fish portion in the air fryer. Overcrowding reduces air circulation and can prevent the coating from becoming crisp.
