Detailed Directions and Instructions
Step 1: Prepare the Potatoes
Scrub the potatoes thoroughly, then chop them into 1cm cubes. Place the cubed potatoes in the large air-fryer drawer. Add 1½ tablespoons of olive oil along with a pinch of sea salt and black pepper. Cook the potatoes at a temperature of 200ºC for 20 minutes or until they are golden brown, shaking the drawer halfway through the cooking time to ensure even cooking.
Step 2: Make the Sauce
In a blender, combine the Cheddar cheese, creamed horseradish, soured cream, half of the baby spinach, and most of the dill (including stalks). Add 50ml of water and squeeze in the juice of a quarter of the lemon. Blitz the mixture until it becomes smooth, then season to taste with salt and pepper. Remove the shelf from the small air-fryer drawer, pour the sauce into the drawer, and then replace the shelf.
Step 3: Prepare the Fish
Season the fish fillets with salt and pepper. Place them in the small air-fryer drawer on top of the sauce. Finely slice 4 rounds from the remaining lemon and place these slices on top of the fish. Lightly spritz the fish with olive oil. Cook the fish at 170ºC for 12 to 15 minutes, or until the fish is just cooked through and the sauce is heated.
Step 4: Wilt the Spinach and Serve
Once the potatoes are done, carefully tip them out of the large drawer. Pack the remaining baby spinach into the drawer with the potatoes. Cook for an additional 2 minutes at 200ºC, just until the spinach is wilted. While the spinach wilts, remove the fish from the small drawer. Divide the sauce between serving plates, then arrange the fish, cooked potatoes, and wilted spinach on top. Garnish the dishes with the reserved dill and finish with a drizzle of extra virgin olive oil, if desired.
Notes
Note 1: Fish Selection
Ensure that the fish you choose is skin off and pin-boned, and sourced from sustainable suppliers to support responsible fishing practices.
Note 2: Temperature Accuracy
Cooking times and temperatures may vary depending on the model of your air fryer. Adjust accordingly based on your specific appliance for the best results.
Note 3: Sauce Consistency
If the sauce is too thick, you can thin it out by adding a bit more water until you reach your desired consistency.
Note 4: Serving Suggestions
This dish pairs well with a light salad or crusty bread to balance the rich flavors of the fish and sauce. Adjust garnishes with additional herbs to enhance flavors.
