Ingredients

Scale

Herb Mixture

25g bunch parsley
12g (half a bunch) chives
1 lemon (zested and cut into wedges)

Bean Mixture

2 large tins (700g) butter beans, rinsed and drained
125ml chicken, fish, or vegetable stock
15g (3 tbsp) grated parmesan cheese
2 tbsp creme fraiche
1 garlic clove, minced

Asparagus and Cod

1 pack asparagus (trimmed and cut into 3–4 cm pieces)
4 cod fillets
1 garlic clove

Herby Mayo

2 tbsp mayonnaise
1 tbsp lemon juice (from lemon wedges)
Salt and pepper to taste

Instructions

Preheat or Prepare Air Fryer: If using an oven, preheat to 190°C (375°F) fan. If air frying, no need to preheat; proceed to next step.
Prepare Herb Mixture: Rinse parsley and chives, finely chop, and discard stalks from parsley. Zest the lemon. Combine chopped parsley, chives, and lemon zest in a bowl. Reserve ¼ of this mixture for coating the cod later.
Make Bean Mixture: In a roasting dish suitable for an air fryer or oven, mix butter beans, stock, grated parmesan, the remaining herb and lemon zest mixture, creme fraiche, and minced garlic. Season with salt and pepper to taste.
Cook Beans: Air fry the bean mixture at 180°C (355°F) for 10 minutes without preheating, or bake in the oven at 190°C (375°F) for 13 minutes. Check thickness and softness; cook an additional 3 minutes if needed until the beans are soft and the liquid is thickened.
Prepare Asparagus: While beans are cooking, wash asparagus, trim 2cm from the base, and cut into 3-4 cm pieces.
Make Herby Mayo: Combine the reserved ¼ herb and lemon zest mixture with mayonnaise, 1 tablespoon lemon juice from wedges, and salt and pepper.
Season Cod: Pat cod fillets dry, season generously with salt and pepper. Spread the herby mayo evenly over each fillet.
Assemble for Final Cooking: Once beans are cooked, add chopped asparagus to the roasting dish, then arrange cod fillets on top.
Cook Cod and Asparagus: Air fry at 200°C (390°F) for 7-12 minutes or bake in the oven at 220°C (430°F) for 7-12 minutes, depending on cod thickness. The cod is done when it flakes easily with a fork.
Serve: Serve immediately with remaining lemon wedges on the side for extra zest.

Notes

Trim asparagus to remove woody ends for a better texture.
Check cod doneness by gently flaking with a fork to avoid overcooking.
Use one type of stock (chicken, fish, or vegetable) based on dietary preference or availability.
The air fryer method reduces cooking time and enhances the crisp texture on cod.
Adjust seasoning and lemon juice to taste for balancing acidity and flavor.
