The Preparation
Preheat oven broiler.
Place baguette slices on a baking sheet and drizzle lightly with olive oil. Toast under the broiler 1-2 minutes until lightly golden. Set aside.
In a bowl, combine the artichoke hearts, red onion, garlic, mayonnaise, cream cheese, and all cheeses. Season with Old Bay, salt, and pepper. Mix well.
Spoon a generous mound of the artichoke mixture onto each toasted baguette slice.
Return to the oven and broil for 3-5 minutes until the topping is bubbly, hot, and golden brown on top.
Serve immediately.
