Set your oven to 475˚F. Spread a tablespoon of olive oil across the bottom of a 9x13-inch pan to stop sticking. Keep it aside.

Cut the stem to leave about an inch, slice the top inch off the artichoke, and peel away the bottom 3 layers of harder leaves. Trim away any dark green bits and slice the artichokes in half lengthwise. Scoop out the fuzzy center.

In a big dish or container, pour 8 cups of water and squeeze the juice from a lemon into it.

Let the artichoke halves sit in the lemon water for 3 to 5 minutes. Shake off the extra moisture, then toss them in a big bowl with 2 tablespoons of olive oil, ¼ teaspoon black pepper, and ¾ teaspoon salt.

Put the artichokes, cut-side facing down, in the greased baking dish. Slice the other 2 lemons in half and place them cut-side up near the artichokes. Cover everything with foil and bake for 25 to 30 minutes until you can pierce the leaves easily and they’re golden. Shift them to a plate after baking.

Get the juice out of the roasted lemons into a bowl. Stir in the rest of the olive oil, Dijon mustard, parsley, and garlic. Add salt and pepper to taste.

Pour the lemony sauce over the hot artichokes, top with some more parsley, and enjoy while warm.
