Make the casserole
- Preheat oven to 350°F (180°C).
- Oil a 9 x 13–in. (23 x 33–cm) baking dish.
- Cover bottom of dish with artichokes halves. Top with tomatoes, then with onion. Sprinkle garlic and herbs to cover, then drizzle with olive oil. Season to taste.
- In a large bowl, combine topping ingredients and spread evenly over the vegetables.
- Bake the casserole for 40 to 45 min.
Tip: To chop almonds, put them in a small, sturdy plastic bag, and crush with a rolling pin or a meat mallet.
Trim fresh artichokes
- Using a serrated knife, cut off the prickly head of an artichoke and its fibrous bottom, then discard.
- Using a paring knife, peel base and stem of artichoke, and remove larger outer leaves.
- Using a dessert spoon, remove core from artichoke (the fuzzy centre part of the vegetable).
- Transfer trimmed artichoke to a bowl filled with cold water and juice of 1 lemon (to prevent oxidation).
- Repeat operation with the other artichokes.
- In a large saucepan, bring water with a pinch of salt to a boil. Drain artichokes and add to saucepan. Cover with a lid that’s smaller than the actual saucepan lid, to prevent artichokes from floating, so they will cook evenly. Cook for 5 min.
