Ingredients

• 4 cups Artichoke hearts (canned or frozen, drained if canned)
• 2 large Yellow onions
• 3 tablespoons Olive oil
• 3 cloves Garlic cloves
• 2 teaspoons Lemon zest
• 2 tablespoons Fresh lemon juice
• 1 cup Heavy cream
• 1 cup Parmesan cheese, finely grated
• 1 cup Breadcrumbs (preferably panko)
• 2 tablespoons Fresh parsley, finely chopped
• 1 teaspoon Salt
• 0.5 teaspoon Ground black pepper
• 2 tablespoons Butter, melted

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Thinly slice the onions and finely mince the garlic.

Step 3

Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the onions and a pinch of salt, cooking until soft and caramelized, about 15 minutes. Stir occasionally to prevent burning.

Step 4

Add the minced garlic to the onions and cook for another 2 minutes until fragrant.

Step 5

In a large mixing bowl, combine the caramelized onions, artichoke hearts, lemon zest, lemon juice, heavy cream, 1/2 cup of Parmesan cheese, salt, and pepper. Mix until evenly coated.

Step 6

Transfer the mixture to a greased 9x9-inch (or similar-sized) baking dish, spreading it out evenly.

Step 7

In a small bowl, combine the breadcrumbs, the remaining 1/2 cup of Parmesan cheese, parsley, melted butter, and 1 tablespoon of olive oil. Mix until the breadcrumbs are evenly moistened.

Step 8

Sprinkle the breadcrumb mixture evenly over the artichoke and onion mixture in the baking dish.

Step 9

Bake in the preheated oven for 25–30 minutes, or until the top is golden brown and the gratin is bubbling around the edges.

Step 10

Let the gratin cool for 5 minutes before serving. Garnish with additional parsley, if desired.
