Heat the oven to 180C/160C fan/ gas 4. Lightly oil a small baking dish. Tip the defrosted spinach into a sieve set over the sink and press down with the back of a large spoon to remove as much liquid as possible. Set aside.

Whisk the soft cheese, soured cream and mayonnaise together in a medium bowl until well-combined. Add the garlic, most of the cheeses, all the spinach and the artichokes. Season with black pepper and fold everything together to combine.

Spoon the mixture into the baking dish and sprinkle over the remaining cheese. Will keep, covered in the fridge, for up to a day. Bake for 25-30 mins until bubbling and golden. If you like an extra-crisp top, flash under a hot grill for the final few minutes of cooking time. Leave to stand for 5 mins, then serve with tortilla chips and crudités.
