This elegant vegetarian side dish brings a refined touch to any Sunday roast or festive spread. The natural sweetness of the pearl onions and the subtle aniseed notes of the fennel are perfectly balanced by a luxurious double cream reduction. It is a comforting yet sophisticated bake that offers a wonderful contrast between the silky vegetables and a crisp, aromatic topping.
Infused with bright orange zest and a hint of chilli heat, the golden Parmesan breadcrumbs provide an irresistible crunch. This recipe is an excellent choice for those looking to elevate a standard vegetable accompaniment into something truly special. Serve it alongside roasted roots or as a standalone star for a vegetarian main, making sure to let it rest briefly so the creamy sauce thickens beautifully before serving.

How to make Creamed Pearl Onions and Fennel with Crispy Spiced Breadcrumbs
Back to contentsPosition rack in middle of oven and preheat to 400ºF. Brush a 2-qt. gratin or baking dish, preferably oval or rectangular, with 1/2 tablespoons butter.
Cut fennel bulb and stems into 1/4" pieces. Finely chop 2 tablespoons fennel fronds; set aside.
Combine onions, fennel bulb and stems, 1/4 teaspoons salt, and 180ml water in a large saucepan. Bring to a boil over high heat, stirring occasionally. Reduce heat to medium, cover, and simmer 5 minutes. Drain onion mixture, pat dry, and transfer to prepared dish.
Bring cream and 1/2 teaspoons salt to a boil in a small saucepan over medium-high heat, then pour over onion mixture. Bake 15 minutes.
Meanwhile, combine orange zest, breadcrumbs, cheese, parsley, black pepper, red pepper flakes, reserved fennel fronds, 1/2 teaspoons salt, and remaining 3 1/2 tablespoons melted butter in a medium bowl.
Remove onion mixture from oven and top with breadcrumb mixture. Return to oven and continue baking until breadcrumbs are deep golden brown and cream is bubbling around the edges, 25–30 minutes. Let rest 10 minutes before serving.
