Place the panko, herbs and pepper flakes in a shallow dish and mix well. Set aside.
Cut the artichokes in half, and gently toss with oil and a sprinkle of salt and pepper.
Roll each artichoke in the crumb mixture and place on a parchment lined baked sheet. Bake at 400°F for 15 minutes, flipping them halfway through cooking.
For the sauce, combine all ingredients into a dish and blend until smooth. Season to taste with salt and pepper.
