Preheat oven to 350 degrees Fahrenheit (175 degrees Celsius). Spray a Pyrex dish very well with cooking spray or line a 9 x 13-inch (23 x 33-centimeter) pan with parchment paper.

Place meat, parsley, and spices in a medium-sized bowl and mix until well-combined.

Place onions in the food processor and blend until it reaches a creamy consistency. Add to the meat mixture.

Wash and dry all artichokes well. Fill the artichoke bottoms with the meat mixture. Fill generously because the meat shrinks while cooking. Place all the filled artichokes in the pan.

Combine the sauce ingredients in a glass cup and mix well.

Pour one to two spoonsful of the sauce over each artichoke. Whatever is left, pour into the pan. Try to make sure that there’s liquid on the entire surface of each artichoke. Drizzle olive oil over everything.

Cover with a layer of parchment paper and then double cover tightly with aluminum foil.

Bake for one hour, then lower the temperature to 250 degrees Fahrenheit (120 degrees Celsius) for two hours.
